Opening email with file attachment causes app crash on Android 8

[Dave Alden]

File access has been changed on Android 8, so using the current plugin implementation to attach a file to an email causing a crash on Android 8:

To reproduce, just create a Cordova test project and run the example code on deviceready in Android 8 emulator/device:

cordova.plugins.email.open({
    attachments: [
        'file://img/logo.png', //=> assets/www/img/logo.png (Android)
        'file://css/index.css' //=> www/css/index.css (iOS)
    ]
});

The same code runs fine on Android 7.1.1 and below.

Seems there is a potential solution in this SO post.

When will this be fixed?

I‘m not planning to release a new version as I‘m going to discontinue the development of this plugin

@dpa99c @seanda Don't worry brother. Use the following plugin instead of this
https://github.com/katzer/cordova-plugin-email-composer

[Pliable Pixels]

https://github.com/katzer/cordova-plugin-email-composer requires the GET_ACCOUNTS permission which is too permissive. dpa99c since you seem to be a plugin genius, have you managed to fork it and fix it ?

Edit: Problem solved with https://github.com/EddyVerbruggen/SocialSharing-PhoneGap-Plugin#email
