Disable Prompting of Sale Amount Screen on Clover Mini after Android 10 Upgrade

While our app is in the CustomerMode, we have added a service to run in the background and suppress the Sale prompt that appears when you dip or swipe a card. This worked fine previously but after the Android 10 upgrade, it seems like the issue has reappeared.

Our service is written as below.

public class IntentSuppressionService extends Service {
    private static final String ACTION_BROADCAST_CARD_INSERTED = "com.clover.intent.action.broadcast.CARD_INSERTED";
    private static final String ACTION_BROADCAST_CARD_SWIPED = "com.clover.intent.action.broadcast.CARD_SWIPED";
    private static final int PRIORITY_INTERCEPT = 200;
    private static String TAG = IntentSuppressionService.class.getName();

    private BroadcastReceiver suppressCardInsertedIntentReceiver = null;

    public static void start(Context context) {
        context.startService(new Intent(context, IntentSuppressionService.class));

    public static void stop(Context context) {
        context.stopService(new Intent(context, IntentSuppressionService.class));

    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.d(TAG, "Intent suppression background service is starting");
        return START_STICKY;

    public void onCreate() {

        IntentFilter filter = new IntentFilter();

        if (suppressCardInsertedIntentReceiver == null) {
            suppressCardInsertedIntentReceiver = new BroadcastReceiver() {
                public void onReceive(Context context, Intent intent) {
                    String action = intent != null ? intent.getAction() : null;
                    if (ACTION_BROADCAST_CARD_INSERTED.equals(action) || ACTION_BROADCAST_CARD_SWIPED.equals(action)) {
                        Log.i(TAG, "Intent suppression background service is suppressing intent: " + action);
                        if (isOrderedBroadcast()) {

            registerReceiver(suppressCardInsertedIntentReceiver, filter);

            Log.d(TAG, "Intent suppression background service broadcast receiver created");

    public void onDestroy() {
        if (suppressCardInsertedIntentReceiver != null) {
            suppressCardInsertedIntentReceiver = null;

            Log.d(TAG, "Intent suppression background service broadcast receiver destroyed");

    public IBinder onBind(Intent intent) {
        return null;

The sale screen appears intermittently. Are we missing any new intent?

There's no guarantee your service will remain running. As it's not a foreground service your process is a likely target for the OS to reclaim memory. Behaviors around memory management can change between Android versions. Most probably your process is being reaped under some conditions which would explain the sporadic nature of the failures. I'd suggest you use a foreground service.

I don't know the history of where you learned of these actions, but FYI, those two intent actions you are listening to are not public. If it's not in our public SDK it's subject to behavior change or removal.
