Redirect to Notification Access Settings

Question

I\'m currently developing an app for Android that uses the NotificationListenerService, which requires that the user will enable notification access for my app

Answer 1

Many Thanks to @adneal and @Waboodoo. I am posting this for an complete answer

Check permission granted or not using this method

private boolean isNotificationServiceRunning() {
    ContentResolver contentResolver = getContentResolver();
    String enabledNotificationListeners =
            Settings.Secure.getString(contentResolver, "enabled_notification_listeners");
    String packageName = getPackageName();
    return enabledNotificationListeners != null && enabledNotificationListeners.contains(packageName);
}

Then show settings activity, if necessary

boolean isNotificationServiceRunning = isNotificationServiceRunning();
if(!isNotificationServiceRunning){
    startActivity(new Intent(Settings.ACTION_NOTIFICATION_LISTENER_SETTINGS));
}

Answer 2

You can always use the notification manager to check if notifications are enabled at the OS level:

NotificationManagerCompat.from(context).areNotificationsEnabled()

Answer 3

You can open the NotificationAccessSettingsActivity by using the following Intent, but I'm not sure about checking to see if they've already enabled your app.

startActivity(new Intent("android.settings.ACTION_NOTIFICATION_LISTENER_SETTINGS"));

Alternatively, for API 22+:

startActivity(new Intent(Settings.ACTION_NOTIFICATION_LISTENER_SETTINGS));
