Can't start activity from BroadcastReceiver on android 10

Question

I updated my OS version to android 10 last night, and since then the startActivity function inside the broadcast receiver is doing nothing. This is how I try to start the ac

You can use SYSTEM_ALERT_WINDOW to force launch activity window in android 10, refer to this settingsuperposition setting:

in launched app check permissions:

private void RequestPermission() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        if (!Settings.canDrawOverlays(this)) {
            Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
                    Uri.parse("package:" + this.getPackageName()));
            startActivityForResult(intent, ACTION_MANAGE_OVERLAY_PERMISSION_REQUEST_CODE);
        } else {
            //Permission Granted-System will work
        }
    }
}

you will can user intent as android older versions

public class OnBootReceiver extends BroadcastReceiver {
    private static final String TAG = OnBootReceiver.class.getSimpleName();

    @Override
    public void onReceive(Context context, Intent intent) {
        try {
            Intent activity = new Intent(context, MainActivity.class);
            activity.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(activity);
        } catch (Exception e){
            Log.d(TAG,e.getMessage()+"");
        }
    }
}
