Android M shortcut install/uninstall duplication

Question

I am trying to create a shortcut for my application through a service. The following code is working on SDK <= 21, but its not working correctly on SDK = 23

The creation of the shortcut is done this way:

        Intent shortcutIntent = new Intent(this, MainActivity.class);
        shortcutIntent.putExtra(EXTRA_SHORTCUT_CLICKED, true); //This is only to check when the user clicked on the created shortcut
        shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);

        Intent addIntent = new Intent();
        addIntent.putExtra("duplicate", false);
        addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
        addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "TEST");
        addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, Intent.ShortcutIconResource.fromContext(context, R.drawable.application_icon));
        addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);

        sendBroadcast(addIntent);

In SDK <= 21 the shortcut is created and if already exists it will not create other instance.

In SDK = 23 the shortcut will only be duplicated if I press the created shorcut and try to create the shortcut again, or If I reboot the device and then try to create the shortcut again.

I tried to uninstall the shortcut first but without success on SDK 23, as follows:

        Intent shortcutIntent = new Intent(this, MainActivity.class);
        shortcutIntent.putExtra(EXTRA_SHORTCUT_CLICKED, true); //This is only to check when the user clicked on the created shortcut
        shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);

        Intent addIntent = new Intent();
        addIntent.putExtra("duplicate", false);
        addIntent.setAction("com.android.launcher.action.UNINSTALL_SHORTCUT");
        addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "TEST");
        addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, Intent.ShortcutIconResource.fromContext(context, R.drawable.application_icon));
        addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);

        sendBroadcast(addIntent);

This is the service implementation:

public class MyService extends Service {

 @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        createShortcut(); //This is where I create the shortcut
        return super.onStartCommand(intent,flags,startId);
    }
}

Did Android 6 changed the shortcut creation politics? I cannot find anything on the documentation.

[UPDATE] I tried to make this shortcut creation by clicking on a button on a sample application and this still happens. The shorcut will duplicate once I click on the created shortcut and then try to create it again. Same thing happens rebooting the device.

[UPDATE2] I was looking on the grep code for the Launcher3 google application and I found that the shortcut installation calls the registerSessionCallback which depends on the calling thread. Might be an issue regarding these new changes?

Answer 1

For people who got stuck with the same issue:

Google removed support of Uninstall shortcut on Launcher3 and Google now Launcher on Android M.

Additionally, the duplication of shortcuts is an issue on the lastest Android M build (MRA58K) and its now on the development team hands.

You guys can follow the issue here, https://code.google.com/p/android/issues/detail?id=179697

[UPDATE] Google has just fixed the issue and it will be released on the next version.
