Question

I need help how to send push notifications on successful payment with transaction I'd to user

Answer 1

Use one of the background workers if you want to check the status of your transaction in background. I will use WorkManager.
implementation "android.arch.work:work-runtime:1.0.1"
public class SynchronizeWorker extends Worker {
static final String TAG = "MYWORKER";
public SynchronizeWorker(#NonNull Context context, #NonNull WorkerParameters workerParams) {
super(context, workerParams);
}
private Notification getNotification() {
NotificationManager mNotificationManager =
(NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel("default",
"WTF_CHANNEL",
NotificationManager.IMPORTANCE_DEFAULT);
channel.setDescription("WTF_CHANNEL_DESCRIPTION");
mNotificationManager.createNotificationChannel(channel);
}
// specify the class of the activity you want to open after click on notification
Intent intent = new Intent(getApplicationContext(), MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(
getApplicationContext(),
0,
intent,
0);
return new NotificationCompat.Builder(getApplicationContext(), "default")
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(getApplicationContext().getResources().getString(R.string.notification_header))
.setContentText(getApplicationContext().getResources().getString(R.string.notification_text))
.setAutoCancel(true)
.setWhen(System.currentTimeMillis())
.setContentIntent(pendingIntent)
.build();
}
#NonNull
#Override
public Result doWork() {
Log.d(TAG, "status checking started");
// check your transaction status here and show notification
try {
TimeUnit.SECONDS.sleep(10);
} catch (InterruptedException e) {
Log.d(TAG, "status checking finished");
}
Log.d(TAG, "status checking finished");
NotificationManagerCompat
.from(getApplicationContext())
.notify((int)(Math.random() * 10), getNotification());
return Result.success();
}
}
And then enqueue worker where you want to check status
OneTimeWorkRequest myWorkRequest = new OneTimeWorkRequest.Builder(SynchronizeWorker.class).build();
WorkManager.getInstance().enqueue(myWorkRequest);
I understand that it is probably not exactly what you want, but hope it will help somehow:)
