Current behavior:

Cold restart closes the app but does not reopen the app in Android 10, leaving the viewer on the home screen. Testing on Android 9 and lower cold restart behaves as desired. Warm restart behaves as desired on Android 10.

Expected behavior:

Cold restart is desired to close then reopen app.

Steps to reproduce:

Programatically hit this function cordova.plugins.diagnostic.restart(onError, true);

**** UPDATE Updating this block in doColdRestart resolves the issue for me, works on 7 - 10 (the versions available for me to test on)

protected void doColdRestart() {
        String baseError = “Unable to cold restart application: “;
        try {
           ...
                    if (mStartActivity != null) {
                        mStartActivity.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
                        c.getApplicationContext().startActivity(mStartActivity);  <--------- Replaced PendingIntent and AlarmManager
                        Log.i(TAG,“Killing application for cold restart”);
                        //kill the application
                        System.exit(0);
