I want to create a simple notification in my app, but I can't. I searched for that, I read questions here and the google doc, but I don't know why it is not working. I watched that code from a video, but it doesnt work too.
private final String CHANNEL_ID = "personal_notifications";
private final int NOTIFICATION_ID = 001;
public void displayNotification(View view) {
NotificationCompat.Builder builder = new NotificationCompat.Builder(this,CHANNEL_ID);
builder.setSmallIcon(R.drawable.power);
builder.setContentTitle("Noti");
builder.setContentText("mukodj mar");
builder.setPriority(NotificationCompat.PRIORITY_DEFAULT);
NotificationManagerCompat notificationManagerCompat = NotificationManagerCompat.from(this);
I use this code in a BroadcastReceiver:
public class NotificationReceiver extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Intent repeating_intent = new Intent(context, MainActivity.class);
repeating_intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 100, repeating_intent, PendingIntent.FLAG_UPDATE_CURRENT);
StringBuilder sb = new StringBuilder();
NotificationCompat.BigTextStyle contentStyle = new NotificationCompat.BigTextStyle();
contentStyle.bigText((CharSequence) sb.toString());
NotificationCompat.Builder builder = new NotificationCompat.Builder(context) // channel ID missing
.setContentIntent(pendingIntent)
.setSmallIcon(R.drawable.icon)
.setStyle(contentStyle)
.setContentTitle("Title")
.setContentText(sb.toString())
.setAutoCancel(true);
notificationManager.notify(100, builder.build());
}
I think you forgot the last line:
notificationManager.notify(100, builder.build());
I got it. I made notification channel and its working now, anyway thanks guys!

I have an app that sends/receives notification using Firebase. Im sending the notification with no problem, but if the app is open the notification display an square instead of the smallicon also if i click the notification nothing happens, but if i'm using a different app i receive the notification and the notification show the correct icon and also opens the app.
public class MyMessagingService extends FirebaseMessagingService {
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
showNotification(remoteMessage.getNotification().getTitle(), remoteMessage.getNotification().getBody());
}
public void showNotification(String title, String message) {
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "MyNotifitcation")
.setContentTitle(title)
.setSmallIcon(R.drawable.ic_launcher_background)
.setAutoCancel(true)
.setContentText(message);
NotificationManagerCompat manager = NotificationManagerCompat.from(this);
manager.notify(999, builder.build());
}
}
public class MainActivity extends AppCompatActivity {
private String TAG = MainActivity.class.getSimpleName();
String title;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel =
new NotificationChannel("MyNotifitcation", "MyNotifitcation", NotificationManager.IMPORTANCE_DEFAULT);
NotificationManager manager = getSystemService(NotificationManager.class);
manager.createNotificationChannel(channel);
}
FirebaseMessaging.getInstance().subscribeToTopic("general").addOnCompleteListener(new OnCompleteListener<Void>() {
#Override
public void onComplete(#NonNull Task<Void> task) {
String msg = "Successfull";
if (!task.isSuccessful()) {
msg = "Failed";
}
// Toast.makeText(MainActivity.this, msg, Toast.LENGTH_SHORT).show();
}
});
}
}
For Notification click add Pending intent to notification builder. and for adding image/icon to notification use setSmallIcon() in notification builder. below is my notification code.
private void sendNotification(String body, String title) {
Intent intent = new Intent(this, NotificationActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("action_type", "notify");
PendingIntent pendingIntent = PendingIntent.getService(getApplicationContext(), 0, intent,
PendingIntent.FLAG_ONE_SHOT);
NotificationCompat.Builder notificationBuilder = new
NotificationCompat.Builder(this,"channel")
.setSmallIcon(R.drawable.logo)
// .setContent(contentView)
.setContentTitle("title")
.setContentText("body")
.setAutoCancel(true)
.setContentIntent(pendingIntent);
Notification notification = notificationBuilder.build();
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(0, notification);
}
See below code. Opening Activity.

NotificationManager notificationManager = (NotificationManager) context

notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, notification);
I am stuck with my app which needs to repeat one notification after one hour (Medical purpose). As my field is totally opposite and I am noob in coding any help will be appreciated. I know I have to add something in notification receiver to repeat notifications. But every time I try to repeat the app crashes.
(This is a little but unique idea to solve a real world problem I will credit everyone from whom I've received even a little help )
Here is my MainActivity
private NotificationManagerCompat manager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
manager = NotificationManagerCompat.from(this);
}
public void Shownotification(View v) {
String title = "You Did it!";
String message = "Some Text";
Notification notification = new NotificationCompat.Builder(this, CHANNEL_1_ID)
.setSmallIcon(R.drawable.ic_launcher_foreground)
.setContentTitle(title)
.setContentText(message)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setCategory(NotificationCompat.CATEGORY_MESSAGE)
.build();
manager.notify(0,notification);
}
Notification Channel
public class App extends Application {
public static final String CHANNEL_1_ID = "channel1";
public static final String CHANNEL_2_ID = "channel2";
#Override
public void onCreate() {
super.onCreate();
createNotificationChannels();
}
private void createNotificationChannels() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel1 = new NotificationChannel(
CHANNEL_1_ID,
"Channel 1",
NotificationManager.IMPORTANCE_HIGH
);
channel1.setDescription("This is Channel 1");
NotificationChannel channel2 = new NotificationChannel(
CHANNEL_2_ID,
"Channel 2",
NotificationManager.IMPORTANCE_LOW
);
channel2.setDescription("This is Channel 2");
NotificationManager manager = getSystemService(NotificationManager.class);
manager.createNotificationChannel(channel1);
manager.createNotificationChannel(channel2);
}
}
Notification Reciever
public class NotificationReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
String title = "You Did it!";
String message = "Some Text";
Notification notification = new NotificationCompat.Builder(context, CHANNEL_1_ID)
.setSmallIcon(R.drawable.ic_launcher_foreground)
.setContentTitle(title)
.setContentText(message)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setCategory(NotificationCompat.CATEGORY_MESSAGE)
.build();
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notification);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.add(Calendar.MINUTE, 1);
Intent i = new Intent("android.action.DISPLAY_NOTIFICATION");
i.addFlags(Intent.FLAG_INCLUDE_STOPPED_PACKAGES);
PendingIntent broadcast = PendingIntent.getBroadcast(context, 100, intent, PendingIntent.FLAG_CANCEL_CURRENT);
alarmManager.setExact(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), broadcast);
}
you can set new notification when previous one triggers.in onReceive Method of BroadcastReceiver.
So, I'm developing an Android App and I need to send a notification of a certain event at a certain time.
However, for some reason the notification itself isn't showing up, despite the app not returning any errors or anything of the sort.
What could I possibly be doing wrong? This is my Receiver class.
The test print works properly so I don't think the connection to the receiver is the problem.
public class NotReceiver extends BroadcastReceiver{
#RequiresApi(api = Build.VERSION_CODES.O)
#Override
public void onReceive(Context context, Intent intent) {
System.out.println("test");
NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
builder.setAutoCancel(true)
.setDefaults(Notification.DEFAULT_ALL)
.setContentTitle("doge")
.setContentText("456")
.setSmallIcon(R.mipmap.ic_launcher)
.build();
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(1, builder.build());
}
}
This is my Alarm function
#RequiresApi(api = Build.VERSION_CODES.O)
public void sendNotif(View view) {
AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent myIntent;
PendingIntent pendingIntent;
myIntent = new Intent(EventsActivity.this, NotReceiver.class);
pendingIntent = PendingIntent.getBroadcast(this, 0, myIntent, 0);
am.set(AlarmManager.RTC_WAKEUP, SystemClock.elapsedRealtime()+100, pendingIntent);
}
Is it possible (and if yes how) to make push notification sound repeat until it's read? I am creating app that notifies user about new event in app, but user needs to read notification as soon as possible. When user "reads" notification it should stop ringing. Here's code:
public class GCMIntentService extends IntentService {
String mes;
HelperGlobals glob;
public GCMIntentService() {
super("GcmIntentService");
}
#SuppressLint("SimpleDateFormat")
protected void onHandleIntent(Intent intent) {
Bundle extras = intent.getExtras();
glob = (HelperGlobals) getApplicationContext();
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
String messageType = gcm.getMessageType(intent);
// .... Doing work here
GcmBroadcastReceiver.completeWakefulIntent(intent);
}
public void createPush(String title, String msg, Intent intent) {
Uri soundUri = Uri.parse("android.resource://example.project.com/" + R.raw.notification);
Context context = getApplicationContext();
Intent notificationIntent = new Intent(context, DoNothing.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP
| Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent pIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
Notification n = new Notification.Builder(this)
.setContentTitle(title)
.setContentText(msg)
.setSmallIcon(R.drawable.ic_launcher)
.setContentIntent(pIntent)
.setAutoCancel(true).build();
n.defaults |= Notification.DEFAULT_VIBRATE;
//n.defaults |= Notification.DEFAULT_SOUND;
n.sound = soundUri;
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(0, n);
}
}
And BroadcastReceiver:
public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.d("BukuLog", "Receiver");
// Explicitly specify that GcmMessageHandler will handle the intent.
ComponentName comp = new ComponentName(context.getPackageName(),
GCMIntentService.class.getName());
// Start the service, keeping the device awake while it is launching.
startWakefulService(context, (intent.setComponent(comp)));
setResultCode(Activity.RESULT_OK);
}
}
like this:
Notification note = mBuilder.build();
//here
note.flags = Notification.FLAG_INSISTENT;
mNotificationManager.notify(1, note);
int FLAG_INSISTENT : Bit to be bitwise-ored into the flags field that if set, the audio will be repeated until the notification is cancelled or the notification window is opened.

I build a notification:
Notification.Builder builder = new Notification.Builder(
getApplicationContext())
.setTicker(
getApplicationContext().getString(
R.string.my_string))
.setSmallIcon(android.R.drawable.sym)
.setContentTitle(
getApplicationContext().getString(
R.string.my_string_two))
.setContentText(a.getB())
.setSound(
RingtoneManager
.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
.setVibrate(new long[] { 10001000 })
.setAutoCancel(true)
.setContentIntent(PendingIntent.getActivity(getApplicationContext(),0,
new Intent()
.setAction(Intent.ACTION_VIEW)
.setType(CallLog.Calls.CONTENT_TYPE)
.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK),
0));
NotificationManager nm = (NotificationManager) getApplicationContext()
.getSystemService(Context.NOTIFICATION_SERVICE);
nm.notify("interstitial_tag", 1, builder.build());
With android 4.0 i've found an error: NoSuchMethodError.
How can i solve it? Do i use Notification.Compact?
Thank you.
Can you try:
public static void sendNotification(Context context, String info){
NotificationCompat.Builder notifyBuilder = new NotificationCompat.Builder(context);
//title notifications
notifyBuilder.setContentTitle(context.getString(R.string.app_name));
//small icon
notifyBuilder.setSmallIcon(R.drawable.ic_launcher);
//set contentText
notifyBuilder.setContentText(info);
notifyBuilder.setVibrate(new long[]{100, 200, 100, 500}); notifyBuilder.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));
//setAutoCancel
notifyBuilder.setAutoCancel(true);
getNotificationManager(context).notify(0, notifyBuilder.build());
}
public final static NotificationManager getNotificationManager(Context context) {
return (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
}
And when you used a new Intent(), please insert a destination class
Intent wrapperIntent = new Intent(context, SenderBroadcast.class);
wrapperIntent.putExtra("KEY_UID", uid);
wrapperIntent.setData(Uri.parse("senderbroadcast://"+uid));
wrapperIntent.setAction("REQUESTCODE_SENDERBROADCAST");
PendingIntent.getActivity(context, RequestCode.REQUESTCODE_SENDERBROADCAST, wrapperIntent, PendingIntent.FLAG_UPDATE_CURRENT);
