Interaction with Camera Plugin
If you are installing this plugin along with cordova-plugin-camera you MUST install cordova-plugin-camera first.
Overview
This Cordova plugin provides a general purpose shim layer for the Android intent mechanism, exposing various ways to handle sending and receiving intents.
Credits
This project uses code released under the following MIT projects:
- https://github.com/napolitano/cordova-plugin-intent (marked as no longer maintained)
- https://github.com/Initsogar/cordova-webintent.git (no longer available on github but the project is forked here: https://github.com/darryncampbell/cordova-webintent) This project is also released under MIT. Credit is given in the code where appropriate
IntentShim
This plugin defines a window.plugins.intentShim
object which provides an API for interacting with the Android intent mechanism on any Android device.
Testing / Example
An example application is available at https://github.com/darryncampbell/plugin-intent-api-exerciser to demonstrate the API and can be used to test the functionality.
Installation
Cordova Version < 7
cordova plugin add https://github.com/darryncampbell/darryncampbell-cordova-plugin-intent.git
Cordova Version >= 7
cordova plugin add com-darryncampbell-cordova-plugin-intent
Supported Platforms
- Android
intentShim.registerBroadcastReceiver
Registers a broadcast receiver for the specified filters
window.plugins.intentShim.registerBroadcastReceiver(filters, callback);
Description
The intentShim.registerBroadcastReceiver
function registers a dynamic broadcast receiver for the specified list of filters and invokes the specified callback when any of those filters are received
Android Quirks
Any existing broadcast receiver is unregistered when this method is called. To register for multiple types of broadcast, specify multiple filters.
Example
Register a broadcast receiver for two filters:
window.plugins.intentShim.registerBroadcastReceiver({
filterActions: [
'com.darryncampbell.cordova.plugin.broadcastIntent.ACTION',
'com.darryncampbell.cordova.plugin.broadcastIntent.ACTION_2'
]
},
function(intent) {
console.log('Received broadcast intent: ' + JSON.stringify(intent.extras));
}
);
intentShim.unregisterBroadcastReceiver
Unregisters the broadcast receiver
window.plugins.intentShim.unregisterBroadcastReceiver();
Description
The intentShim.unregisterBroadcastReceiver
function unregisters the broadcast receiver registered with intentShim.registerBroadcastReceiver(filters, callback);
. No further broadcasts will be received for any registered filter after this call.
Android Quirks
The developer is responsible for calling unregister / register when their application goes into the background or comes back to the foreground, if desired.
Example
Unregister the broadcast receiver when the application receives an onPause event:
bindEvents: function() {
document.addEventListener('pause', this.onPause, false);
},
onPause: function()
{
window.plugins.intentShim.unregisterBroadcastReceiver();
}
intentShim.sendBroadcast
Sends a broadcast intent
window.plugins.intentShim.sendBroadcast(action, extras, successCallback, failureCallback);
Description
The intentShim.sendBroadcast
function sends an Android broadcast intent with a specified action
Example
Send a broadcast intent to a specified action that contains a random number in the extras
window.plugins.intentShim.startActivity(
{
action: "com.darryncampbell.cordova.plugin.intent.ACTION",
extras: {
'random.number': Math.floor((Math.random() * 1000) + 1)
}
},
function() {},
function() {alert('Failed to open URL via Android Intent')}
);
intentShim.onIntent
Returns the content of the intent used whenever the application activity is launched
window.plugins.intentShim.onIntent(callback);
Description
The intentShim.onIntent
function returns the intent which launched the Activity and maps to the Android Activity's onNewIntent() method, https://developer.android.com/reference/android/app/Activity.html#onNewIntent(android.content.Intent). The registered callback is invoked whenever the activity is launched
Android Quirks
By default the android application will be created with launch mode set to 'SingleTop'. If you wish to change this to 'SingleTask' you can do so by modifying config.xml
as follows:
<platform name="android">
...
<preference name="AndroidLaunchMode" value="singleTask"/>
</platform>
See https://www.mobomo.com/2011/06/android-understanding-activity-launchmode/ for more information on the differences between the two.
Example
Registers a callback to be invoked
window.plugins.intentShim.onIntent(function (intent) {
console.log('Received Intent: ' + JSON.stringify(intent.extras));
});
intentShim.startActivity
Starts a new activity using an intent built from action, url, type, extras or some subset of those parameters
window.plugins.intentShim.startActivity(params, successCallback, failureCallback);
Description
The intentShim.startActivity
function maps to Android's activity method startActivity, https://developer.android.com/reference/android/app/Activity.html#startActivity(android.content.Intent) to launch a new activity.
Android Quirks
Some common actions are defined as constants in the plugin, see below.
Examples
Launch the maps activity
window.plugins.intentShim.startActivity(
{
action: window.plugins.intentShim.ACTION_VIEW,
url: 'geo:0,0?q=London'
},
function() {},
function() {alert('Failed to open URL via Android Intent')}
);
Launch the web browser
window.plugins.intentShim.startActivity(
{
action: window.plugins.intentShim.ACTION_VIEW,
url: 'http://www.google.co.uk'
},
function() {},
function() {alert('Failed to open URL via Android Intent')}
);
intentShim.getIntent
Retrieves the intent that launched the activity
window.plugins.intentShim.getIntent(resultCallback, failureCallback);
Description
The intentShim.getIntent
function maps to Android's activity method getIntent, https://developer.android.com/reference/android/app/Activity.html#getIntent() to return the intent that started this activity.
Example
window.plugins.intentShim.getIntent(
function(intent)
{
console.log('Action' + JSON.stringify(intent.action));
var intentExtras = intent.extras;
if (intentExtras == null)
intentExtras = "No extras in intent";
console.log('Launch Intent Extras: ' + JSON.stringify(intentExtras));
},
function()
{
console.log('Error getting launch intent');
});
intentShim.startActivityForResult
Starts a new activity and return the result to the application
window.plugins.intentShim.startActivityForResult(params, resultCallback, failureCallback);
Description
The intentShim.startActivityForResult
function maps to Android's activity method startActivityForResult, https://developer.android.com/reference/android/app/Activity.html#startActivityForResult(android.content.Intent, int) to launch a new activity and the resulting data is returned via the resultCallback.
Android Quirks
Some common actions are defined as constants in the plugin, see below.
Example
Pick an Android contact
window.plugins.intentShim.startActivityForResult(
{
action: window.plugins.intentShim.ACTION_PICK,
url: "content://com.android.contacts/contacts",
requestCode: 1
},
function(intent)
{
if (intent.extras.requestCode == 1)
{
console.log('Picked contact: ' + intent.data);
}
},
function()
{
console.log("StartActivityForResult failure");
});
