notification arrives in bluestack apk emulator, but does not generate notification on smartphone
I have the following code, the notification works normally on the bluestack emulator, but on the samsung smartphone there is no notification, I don't know if it's the device or if I have to declare something in the manifest. I don't think so, because in the emulate it generates notification normally and in the cell it does not generate notification: IS IT MY CELL PHONE CONFIGURATION?
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mRootRef = FirebaseDatabase.getInstance().getReference();
builder = new NotificationCompat.Builder(this);
mRootRef.addChildEventListener(new ChildEventListener() {
@Override
public void onChildAdded(DataSnapshot dataSnapshot, String s) {
builder.setSmallIcon(R.mipmap.ic_launcher);
builder.setContentTitle("Firebase Push Notification");
builder.setContentText("Hello this is a test Firebase notification, a new database child has been added");
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(1, builder.build());
}
@Override
public void onChildChanged(DataSnapshot dataSnapshot, String s) {
}
@Override
public void onChildRemoved(DataSnapshot dataSnapshot) {
}
@Override
public void onChildMoved(DataSnapshot dataSnapshot, String s) {
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
HOW DO I PUT A SOUND IN THE NOTIFICATION IN THIS CODE?
