问题 Uri sound = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + context.getPackageName() + "/" + R.raw.notification_mp3); mBuilder.setSound(sound); I had copied the mp3 (notification_mp3.mp3) file into the raw folder in the res folder. When the notification is triggered it produces given mp3 sound upto Android Nougat but default sound in Android Oreo . I had referred many sites but nothing worked on Android Oreo .

问题 I'm delivering a notification which has 2 action buttons namely "Accept" and "Reject". I'm following this Github repo. When user clicks "Accept", certain conditions are checked and the logic is performed accordingly. UPDATE 2.0 - The problem is that upon clicking "Accept" button, operation is happening successfully but the notification isn't disappearing from the status bar because the id generating here: m = (new Random()).nextInt(10000); is different from here: actionIntent.putExtra("id",

问题 My question is more about what is a good practice than what is possible: Is it a good thing to call NoticationManager.notify() from a worker thread?

So, you must not manipulate your UI from a

问题 I'm working on a notification based app, for which I need to listen to incoming notifications. I've been able to listen to incoming calls, SMS, mail etc. I have no clue how to listen for pings or messages from friends on Whatsapp via code. Can this actually be done? If so, how?

问题 I find myself curious why the setLargeIcon method on Notification.Builder only accepts a Bitmap, with no overload to provide a resource id. Perhaps it was done for performance reasons, but it seems odd as setSmallIcon does accept a res drawable id. Notification.Builder builder = new Notification.Builder(application); // .... builder.setLargeIcon(iconBitmap); // Requires a Bitmap builder.setSmallIcon(iconResId); // Requires a drawable resource ID Notification notification = builder
