Permission denied

Hi,

I've tried to use your service in my app (min SDK 19), but I get an exception:
Caused by: android.view.WindowManager$BadTokenException: Unable to add window android.view.ViewRootImpl$W@51664d3 -- permission denied for this window type

I'm using following permission:
android.permission.SYSTEM_ALERT_WINDOW
android.permission.ACTION_MANAGE_OVERLAY_PERMISSION

You need to request the permission from the user. I solved this issue using the following code in my MainActivity:

public final static int REQUEST_CODE = -1010101;

public void checkDrawOverlayPermission() {
	if (Build.VERSION.SDK_INT > 23 && !Settings.canDrawOverlays(this)) {
		Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
				Uri.parse("package:" + getPackageName()));
		startActivityForResult(intent, REQUEST_CODE);
	}else
		enableService();
}

@Override
protected void onActivityResult(int requestCode, int resultCode,  Intent data) {
	if (requestCode == REQUEST_CODE) {
       		if (Build.VERSION.SDK_INT > 23 && Settings.canDrawOverlays(this)) {
			enableService();
			Toast.makeText(this, "Access granted",Toast.LENGTH_SHORT).show();
		}
	}
}
