Any way to link to the Android notification settings for my app?

Question

Is there any way I can launch an intent to get to Android's notification settings screen for my app (pictured below)? Or an easy way I can make a PreferenceScreen item that just leads here on a click?

Answer 1

The following will work in Android 5.0 (Lollipop) and above:

Intent intent = new Intent();
intent.setAction("android.settings.APP_NOTIFICATION_SETTINGS");

//for Android 5-7
intent.putExtra("app_package", getPackageName());
intent.putExtra("app_uid", getApplicationInfo().uid);

// for Android 8 and above
intent.putExtra("android.provider.extra.APP_PACKAGE", getPackageName());

startActivity(intent);

Notes: This is not officially supported in Android 5-7, but it works just fine. It IS officially supported as of Android 8. This code is not backwards compatible with versions of Android before 5.0.
