Overview

This Cordova/Phonegap plugin for iOS, Android and Windows 10 Mobile is used to manage device settings such as Location, Bluetooth and WiFi. It enables management of run-time permissions, device hardware and core OS features.

The plugin is registered in on npm as cordova.plugins.diagnostic

Important notes

Native environment required

Note that this plugin is intended for use in a native mobile environment. It will NOT work in a browser-emulated Cordova environment, for example by running cordova serve or using the Ripple emulator.

Version 3.1 backward-incompatibility

This version contains backwardly-incompatible renaming of some functions in order to logically separate those which check if a device OS setting is enabled (isSomethingEnabled()) vs those which check if hardware/sensor is available for use by the app (device OS setting is enabled AND app has authorisation AND hardware is present - isSomethingAvailable()).

To avoid breaking existing code which uses the prior function names, either fix the version of the plugin in your config.xml to cordova.plugins.diagnostic@3.0 or update your code to use the revised names detailed in the release notes.

Version 3 backward-incompatibility

In order to make cross-platform use of the shared plugin functions easier, some backwardly-incompatible changes have been made to existing API functions in v3 of the plugin.

To avoid breaking existing code which uses the old API syntax, you can continue to use the v2 API by specifying the plugin version when adding it: cordova.plugins.diagnostic@2

See the release notes page for details of the backward-incompatible changes.

Building for Android

In order to support Android 6 (API 23) runtime permissions, this plugin must depend on libraries only present in API 23+, so you must build using Android SDK Platform v23 or above. To do this you must have Cordova Android platform@5.0.0 or above installed in your project. You can check the currently installed platform versions with the following command:

cordova platform ls

Note: Attempting to build with API 22 or below will result in a build error.

You must also make sure your build environment has the following Android libraries installed. In a local build environment, you'd install these via the Android SDK Manager:

• Android Support Library - Rev. 23 or above
• Android Support Repository - Rev. 23 or above

Building for API 22 or lower

For users who wish to build against API 22 or below, there is a branch of the plugin repo which contains all the functionality except Android 6 runtime permissions. This removes the dependency on API 23 and will allow you to build against legacy API versions (22 and below).

The legacy branch is published to npm as cordova.plugins.diagnostic.api-22, so you'll need to use this plugin ID when adding it:

cordova plugin add cordova.plugins.diagnostic.api-22

NOTE: Phonegap Build now supports API 23, so its users may use the main plugin branch (cordova.plugins.diagnostic).

Installation

Using the Cordova/Phonegap CLI

$ cordova plugin add cordova.plugins.diagnostic
$ phonegap plugin add cordova.plugins.diagnostic

NOTE: Make sure your Cordova CLI version is 5.0.0+ (check with cordova -v). Cordova 4.x and below uses the now deprecated Cordova Plugin Registry as its plugin repository, so using a version of Cordova 4.x or below will result in installing an old version of this plugin.

Using Cordova Plugman

$ plugman install --plugin=cordova.plugins.diagnostic --platform=<platform> --project=<project_path> --plugins_dir=plugins

For example, to install for the Android platform

$ plugman install --plugin=cordova.plugins.diagnostic --platform=android --project=platforms/android --plugins_dir=plugins

PhoneGap Build

Add the following xml to your config.xml to use the latest version of this plugin from npm:

<plugin name="cordova.plugins.diagnostic" source="npm" />

Usage

The plugin is exposed via the cordova.plugins.diagnostic object and provides the following functions:

Android, iOS and Windows 10 Mobile

isLocationAvailable()

Checks if app is able to access device location.

cordova.plugins.diagnostic.isLocationAvailable(successCallback, errorCallback);

On iOS and Windows 10 Mobile this returns true if both the device setting is enabled AND the application is authorized to use location. When location is enabled, the locations returned are by a mixture GPS hardware, network triangulation and Wifi network IDs.

On Android, this returns true if Location mode is enabled and any mode is selected (e.g. Battery saving, Device only, High accuracy) AND if the app is authorised to use location. When location is enabled, the locations returned are dependent on the location mode:

• Battery saving = network triangulation and Wifi network IDs (low accuracy)
• Device only = GPS hardware only (high accuracy)
• High accuracy = GPS hardware, network triangulation and Wifi network IDs (high and low accuracy)

Parameters

• {Function} successCallback - The callback which will be called when operation is successful. This callback function is passed a single boolean parameter which is TRUE if location is available for use.
• {Function} errorCallback - The callback which will be called when operation encounters an error. This callback function is passed a single string parameter containing the error message.

Example usage

cordova.plugins.diagnostic.isLocationAvailable(function(available){
    console.log("Location is " + (available ? "available" : "not available"));
}, function(error){
    console.error("The following error occurred: "+error);
});

isWifiAvailable()

Checks if Wifi is available. On iOS this returns true if the device is connected to a network by WiFi. On Android and Windows 10 Mobile this returns true if the WiFi setting is set to enabled, and is the same as (isWifiEnabled())[#iswifienabled]

On Android this requires permission <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

cordova.plugins.diagnostic.isWifiAvailable(successCallback, errorCallback);

Parameters

• {Function} successCallback - The callback which will be called when operation is successful. This callback function is passed a single boolean parameter which is TRUE if WiFi is available.
• {Function} errorCallback - The callback which will be called when operation encounters an error. This callback function is passed a single string parameter containing the error message.

Example usage

cordova.plugins.diagnostic.isWifiAvailable(function(available){
    console.log("WiFi is " + (available ? "available" : "not available"));
}, function(error){
    console.error("The following error occurred: "+error);
});

isCameraAvailable()

Checks if camera is available. On Android & iOS this returns true if the device has a camera AND the application is authorized to use it. On Windows 10 Mobile this returns true if the device has a rear-facing camera.

cordova.plugins.diagnostic.isCameraAvailable(successCallback, errorCallback);

Parameters

• {Function} successCallback - The callback which will be called when operation is successful. This callback function is passed a single boolean parameter which is TRUE if camera is present and authorized for use.
• {Function} errorCallback - The callback which will be called when operation encounters an error. This callback function is passed a single string parameter containing the error message.

Example usage

cordova.plugins.diagnostic.isCameraAvailable(function(available){
    console.log("Camera is " + (available ? "available" : "not available"));
}, function(error){
    console.error("The following error occurred: "+error);
});

isBluetoothAvailable()

Checks if Bluetooth is available to the app. Returns true if the device has Bluetooth capabilities AND if Bluetooth setting is switched on (same on Android, iOS and Windows 10 Mobile)

On Android this requires permission <uses-permission android:name="android.permission.BLUETOOTH" />

cordova.plugins.diagnostic.isBluetoothAvailable(successCallback, errorCallback);

Parameters

• {Function} successCallback - The callback which will be called when operation is successful. This callback function is passed a single boolean parameter which is TRUE if Bluetooth is available.
• {Function} errorCallback - The callback which will be called when operation encounters an error. This callback function is passed a single string parameter containing the error message.

Example usage

cordova.plugins.diagnostic.isBluetoothAvailable(function(available){
    console.log("Bluetooth is " + (available ? "available" : "not available"));
}, function(error){
    console.error("The following error occurred: "+error);
});

Android and Windows 10 Mobile only

switchToLocationSettings()

Displays the device location settings to allow user to enable location services/change location mode.

cordova.plugins.diagnostic.switchToLocationSettings();

Note: On Android, you may want to consider using the Request Location Accuracy Plugin for Android to request the desired location accuracy without needing the user to manually do this on the Location Settings page.

switchToMobileDataSettings()

Displays mobile settings to allow user to enable mobile data.

cordova.plugins.diagnostic.switchToMobileDataSettings();

switchToBluetoothSettings()

Android and iOS

permissionStatus constants

Both Android and iOS define constants for requesting and reporting the various permission states.

cordova.plugins.diagnostic.permissionStatus

Android

The following permission states are defined for Android:

• NOT_REQUESTED - App has not yet requested access to this permission. App can request permission and user will be prompted to allow/deny.
• GRANTED - User granted access to this permission, the device is running Android 5.x or below, or the app is built with API 22 or below.
• DENIED - User denied access to this permission (without checking "Never Ask Again" box). App can request permission again and user will be prompted again to allow/deny again.
• DENIED_ALWAYS - User denied access to this permission and checked "Never Ask Again" box. App can never ask for permission again. The only way around this is to instruct the user to manually change the permission on the app permissions settings page.

iOS

The following permission states are defined for iOS:

• NOT_REQUESTED - App has not yet requested access to this permission. App can request permission and user will be prompted to allow/deny.
• DENIED - User denied access to this permission. App can never ask for permission again. The only way around this is to instruct the user to manually change the permission in the Settings app.
• RESTRICTED - Permission is unavailable and user cannot enable it. For example, when parental controls are in effect for the current user.
• GRANTED - User granted access to this permission. For location permission, this indicates the user has granted access to the permission "always" (when app is both in foreground and background).
• GRANTED_WHEN_IN_USE - Used only for location permission. Indicates the user has granted access to the permission "when in use" (only when the app is in the foreground).

Example

if(somePermissionStatus === cordova.plugins.diagnostic.permissionStatus.GRANTED){
    // Do something
}

bluetoothState constants

Defines constants for the various Bluetooth hardware states

    cordova.plugins.diagnostic.bluetoothState

Android

• UNKNOWN - Bluetooth hardware state is unknown or unavailable
• POWERED_OFF - Bluetooth hardware is switched off
• POWERED_ON - Bluetooth hardware is switched on and available for use
• POWERING_OFF- Bluetooth hardware is currently switching off
• POWERING_ON- Bluetooth hardware is currently switching on

iOS

• UNKNOWN - Bluetooth hardware state is unknown
• RESETTING - Bluetooth hardware state is currently resetting
• POWERED_OFF - Bluetooth hardware is switched off
• POWERED_ON - Bluetooth hardware is switched on and available for use
• UNAUTHORIZED- Bluetooth hardware use is not authorized for the current application

Example

cordova.plugins.diagnostic.getBluetoothState(function(state){
    if(state === cordova.plugins.diagnostic.bluetoothState.POWERED_ON){
        // Do something with Bluetooth
    }
}, function(error){
    console.error(error);
});

isLocationEnabled()

Returns true if the device setting for location is on. On Android this returns true if Location Mode is switched on. On iOS this returns true if Location Services is switched on.

cordova.plugins.diagnostic.isLocationEnabled(successCallback, errorCallback);

Parameters

• {Function} successCallback - The callback which will be called when operation is successful. This callback function is passed a single boolean parameter which is TRUE if location setting is enabled.
• {Function} errorCallback - The callback which will be called when operation encounters an error. This callback function is passed a single string parameter containing the error message.

Example usage

cordova.plugins.diagnostic.isLocationEnabled(function(enabled){
    console.log("Location setting is " + (enabled ? "enabled" : "disabled"));
}, function(error){
    console.error("The following error occurred: "+error);
});

isLocationAuthorized()

Checks if the application is authorized to use location.

Notes for Android:

• This is intended for Android 6 / API 23 and above. Calling on Android 5 / API 22 and below will always return GRANTED status as permissions are already granted at installation time.

  cordova.plugins.diagnostic.isLocationAuthorized(successCallback, errorCallback);

Parameters

• {Function} successCallback - The callback which will be called when operation is successful. This callback function is passed a single boolean parameter. On iOS this will return TRUE if application is authorized to use location either "when in use" (only in foreground) OR "always" (foreground and background). On Android this will return TRUE if the app currently has runtime authorisation to use location.
• {Function} errorCallback - The callback which will be called when operation encounters an error. This callback function is passed a single string parameter containing the error message.

Example usage

cordova.plugins.diagnostic.isLocationAuthorized(function(enabled){
    console.log("Location authorization is " + (enabled ? "enabled" : "disabled"));
}, function(error){
    console.error("The following error occurred: "+error);
});

getLocationAuthorizationStatus()

Returns the location authorization status for the application.

Note for Android: this is intended for Android 6 / API 23 and above. Calling on Android 5 / API 22 and below will always return GRANTED status as permissions are already granted at installation time.

cordova.plugins.diagnostic.getLocationAuthorizationStatus(successCallback, errorCallback);

Parameters

• {Function} successCallback - The callback which will be called when operation is successful. This callback function is passed a single string parameter which indicates the location authorization status as a permissionStatus constant.
• {Function} errorCallback - The callback which will be called when operation encounters an error. This callback function is passed a single string parameter containing the error message.

Example iOS usage

cordova.plugins.diagnostic.getLocationAuthorizationStatus(function(status){
   switch(status){
       case cordova.plugins.diagnostic.permissionStatus.NOT_REQUESTED:
           console.log("Permission not requested");
           break;
       case cordova.plugins.diagnostic.permissionStatus.DENIED:
           console.log("Permission denied");
           break;

            console.log("Permission permanently denied");
            break;
    }
}, function(error){
    console.error(error);
});

requestLocationAuthorization()

Requests location authorization for the application.

Notes for iOS:

• Calling this on iOS 7 or below will have no effect, as location permissions are are implicitly granted.
• On iOS 8+, authorization can be requested to use location either "when in use" (only in foreground) or "always" (foreground and background).
• This should only be called if authorization status is NOT_DETERMINED - calling it when in any other state will have no effect.
• This plugin adds default messages which are displayed to the user upon requesting location authorization - see the iOS location permission messages section for how to customise them.

Notes for Android:

• This is intended for Android 6 / API 23 and above. Calling on Android 5 / API 22 and below will have no effect as the permissions are already granted at installation time.

• The successCallback is invoked in response to the user's choice in the permission dialog and is passed the resulting authorization status.

  cordova.plugins.diagnostic.requestLocationAuthorization(successCallback, errorCallback, mode);

Parameters

• {Function} successCallback - Invoked in response to the user's choice in the permission dialog. It is passed a single string parameter which defines the resulting authorisation status.
• {Function} errorCallback - The callback which will be called when operation encounters an error. This callback function is passed a single string parameter containing the error message.
• {String} mode - (iOS-only / optional) location authorization mode specified as a locationAuthorizationMode constant. If not specified, defaults to WHEN_IN_USE.

Example iOS usage

cordova.plugins.diagnostic.requestLocationAuthorization(function(status){
    switch(status){

Note that only one request can be made concurrently because the native API cannot handle concurrent requests, so the plugin will invoke the error callback if attempting to make more than one simultaneous request. Multiple permission requests should be grouped into a single call since the native API is setup to handle batch requests of multiple permission groups.

var isRequesting = cordova.plugins.diagnostic.isRequestingPermission();

Example usage

var isRequesting = cordova.plugins.diagnostic.isRequestingPermission();
if(!isRequesting){
    requestSomePermissions();
}else{
    cordova.plugins.diagnostic.registerPermissionRequestCompleteHandler(function(statuses){
        cordova.plugins.diagnostic.registerPermissionRequestCompleteHandler(null); // de-register handler after single call
        requestSomePermissions();
    });
}

Platform Notes

Android

Android permissions

Some of functions offered by this plugin require specific permissions to be set in the AndroidManifest.xml. Where additional permissions are needed, they are listed alongside the function that requires them.

These permissions will not be set by this plugin, to avoid asking for unnecessary permissions in your app, in the case that you do not use a particular part of the plugin. Instead, you can add these permissions as necessary, depending what functions in the plugin you decide to use.

You can add these permissions either by manually editing the AndroidManifest.xml in /platforms/android/, or define them in the config.xml and apply them using the cordova-custom-config plugin, for example:

<platform name="android">
    <plugin name="cordova-custom-config" version="*"/>
    <config-file target="AndroidManifest.xml" parent="/*">
        <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
        <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    </config-file>
</platform>

Android runtime permissions

Android 6 / API 23 introduces the concept of runtime permissions. Similar to iOS, certain "dangerous" permissions must be requested at runtime in addition to being listed in the Android manifest.

Runtime permissions only apply if the device/emulator the app is running on has Android 6.0 or above. If the app is running on Android 5.x or below, runtime permissions do not apply - all permissions are granted at installation time.

This plugin supports checking and requesting of Android runtime permissions.

"Dangerous" runtime permissions

The plugin defines the full list of dangersous permissions available in API 23 as a list of constants available via the cordova.plugins.diagnostic.runtimePermission object. The following permissions are available:

• cordova.plugins.diagnostic.runtimePermission.READ_CALENDAR
• cordova.plugins.diagnostic.runtimePermission.WRITE_CALENDAR
• cordova.plugins.diagnostic.runtimePermission.CAMERA
• cordova.plugins.diagnostic.runtimePermission.READ_CONTACTS
• cordova.plugins.diagnostic.runtimePermission.WRITE_CONTACTS
• cordova.plugins.diagnostic.runtimePermission.GET_ACCOUNTS
• cordova.plugins.diagnostic.runtimePermission.ACCESS_FINE_LOCATION
• cordova.plugins.diagnostic.runtimePermission.ACCESS_COARSE_LOCATION
• cordova.plugins.diagnostic.runtimePermission.RECORD_AUDIO
• cordova.plugins.diagnostic.runtimePermission.READ_PHONE_STATE
• cordova.plugins.diagnostic.runtimePermission.CALL_PHONE
• cordova.plugins.diagnostic.runtimePermission.ADD_VOICEMAIL
• cordova.plugins.diagnostic.runtimePermission.USE_SIP
• cordova.plugins.diagnostic.runtimePermission.PROCESS_OUTGOING_CALLS
• cordova.plugins.diagnostic.runtimePermission.READ_CALL_LOG
• cordova.plugins.diagnostic.runtimePermission.WRITE_CALL_LOG
• cordova.plugins.diagnostic.runtimePermission.SEND_SMS
• cordova.plugins.diagnostic.runtimePermission.RECEIVE_SMS
• cordova.plugins.diagnostic.runtimePermission.READ_SMS
• cordova.plugins.diagnostic.runtimePermission.RECEIVE_WAP_PUSH
• cordova.plugins.diagnostic.runtimePermission.RECEIVE_MMS
• cordova.plugins.diagnostic.runtimePermission.WRITE_EXTERNAL_STORAGE
• cordova.plugins.diagnostic.runtimePermission.READ_EXTERNAL_STORAGE
• cordova.plugins.diagnostic.runtimePermission.BODY_SENSORS

Runtime permission groups

Each runtime permission belongs to a permission group. Requesting a permission also requests authorisation for all other permissions in that group. If other permissions in the group are not defined in the manifest, they will default to DENIED_ALWAYS status. Otherwise, if user grants permission, all other permissions in the group will be granted; if user denies permission, all other permissions in the group will be denied.

Permissions are grouped as follows:

CALENDAR: [READ_CALENDAR, WRITE_CALENDAR],
CAMERA: [CAMERA],
CONTACTS: [READ_CONTACTS, WRITE_CONTACTS, GET_ACCOUNTS],
LOCATION: [ACCESS_FINE_LOCATION, ACCESS_COARSE_LOCATION],
MICROPHONE: [RECORD_AUDIO],
PHONE: [READ_PHONE_STATE, CALL_PHONE, ADD_VOICEMAIL, USE_SIP, PROCESS_OUTGOING_CALLS, READ_CALL_LOG, WRITE_CALL_LOG],
SENSORS: [BODY_SENSORS],
SMS: [SEND_SMS, RECEIVE_SMS, READ_SMS, RECEIVE_WAP_PUSH, RECEIVE_MMS],
STORAGE: [READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE]

Runtime permissions example project

While the cordova-diagnostic-plugin-example illustrates use of runtime permissions in the context of requesting location and camera access, the cordova-diagnostic-plugin-android-runtime-example project explicitly illustrates use of Android runtime permissions with this plugin:

https://github.com/dpa99c/cordova-diagnostic-plugin-android-runtime-example

Android Camera permissions

Note that the Android variant of requestCameraAuthorization() requests the READ_EXTERNAL_STORAGE permission, in addition to the CAMERA permission. This is because the cordova-plugin-camera@2.2+ requires both of these permissions.

So to use this method in conjunction with the Cordova camera plugin, make sure you are using the most recent cordova-plugin-camera release: v2.2.0 or above.

Windows

Supported Windows versions

Currently the plugin only supports Windows 10 and Windows 10 Mobile, not Windows Phone 8.0 or 8.1.

The reason being that the native functionality required by the plugin's current Windows implementation is only available since Windows 10.

For example, isLocationAvailable() invokes Windows.Devices.Geolocation.Geolocator.requestAccessAsync(). And this was only introduced in Windows 10.

Windows Phone 8.x would require a different implementation (even if possible), and I don't plan to add that since the Windows 8.x global marketshare is below 5% and falling, and is also rendered obsolete by Windows 10 Mobile.

Windows 10 Mobile permissions

Some of functions offered by this plugin require specific permissions to be set in the package.windows10.appxmanifest. Where additional permissions are needed, they are listed alongside the function that requires them.

These permissions will not be set by this plugin, to avoid asking for unnecessary permissions in your app, in the case that you do not use a particular part of the plugin. Instead, you can add these permissions as necessary, depending what functions in the plugin you decide to use.

You can add these permissions by manually editing the package.windows10.appxmanifest in /platforms/windows/.

iOS

iOS location permission messages

When location permission is requested on iOS 8+, a message is displayed to the user indicating the reason for the request. These messages are stored in the {project}-Info.plist file under the keys NSLocationAlwaysUsageDescription and NSLocationWhenInUseUsageDescription, which are displayed when requesting to use location always or when in use, respectively.

Upon installing this plugin into your project, it will add the following default messages to your plist:

• NSLocationAlwaysUsageDescription: "This app requires constant access to your location in order to track your position, even when the screen is off."
• NSLocationWhenInUseUsageDescription: "This app will now only track your location when the screen is on and the app is displayed."

To override these defaults, you can either edit the messages directly in the plist file, or to persist the changes between platform updates, use my cordova-custom-config plugin to add overrides directly from the config xml:

config.xml

<platform name="ios">
    <plugin name="cordova-custom-config" version="*"/>
    <config-file platform="ios" target="*-Info.plist" parent="NSLocationAlwaysUsageDescription">
        <string>My custom message for always using location.</string>
    </config-file>
    <config-file platform="ios" target="*-Info.plist" parent="NSLocationWhenInUseUsageDescription">
        <string>My custom message for using location when in use.</string>
    </config-file>
</platform>
