Android notification dont open activity? - java

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.

PendingIntent intent = PendingIntent.getActivity(context, 0,
notificationIntent, 0);
notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, notification);

New Activity not opening on push notification click

I have a class Home.java which runs first on opening the app when I open it to check if the user is logged in or not.
public class Home extends Application {
#Override
public void onCreate() {
super.onCreate();
FirebaseAuth firebaseAuth = FirebaseAuth.getInstance();
FirebaseUser firebaseUser = firebaseAuth.getCurrentUser();
if (firebaseUser != null) {
Intent intent = new Intent(getApplicationContext(), HomeActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
}
}
}
The issue I'm facing is when I'm getting a notification for this app, it is starting from LogIn activity instead of going to HomeActivity.
I'm aware that if I want to open a specific activity from a notification, I need to specify getIntent() in the launcher activity, but I don't have any launcher activity.
When I try to implement getIntent() in Home.java class the method is not getting imported since it doesn't extends the Activity class.
Any help!
NotificationService.java
public class NotificationService extends FirebaseMessagingService {
Uri uri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
String title = remoteMessage.getNotification().getTitle();
String body = remoteMessage.getNotification().getBody();
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this, "Restaurants")
.setContentTitle(title)
.setContentText(body)
.setSmallIcon(R.drawable.ic_launcher_background)
.setSound(uri); //applying default notification sound to the notification
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
int id = (int) System.currentTimeMillis();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel notificationChannel = new NotificationChannel("Restaurants", "demo", NotificationManager.IMPORTANCE_HIGH);
notificationManager.createNotificationChannel(notificationChannel);
}
notificationManager.notify(id, notificationBuilder.build());
}
}
When you want open an activity when click to Notification then use a code like this:
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
String title = remoteMessage.getNotification().getTitle();
String body = remoteMessage.getNotification().getBody();
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this, "Restaurants")
.setContentTitle(title)
.setContentText(body)
.setSmallIcon(R.drawable.ic_launcher_background)
.setSound(uri); //applying default notification sound to the notification
//Create an intent to gom HomeActivity
Intent intent = new Intent(this, HomeActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
notificationBuilder.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
int id = (int) System.currentTimeMillis();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel notificationChannel = new NotificationChannel("Restaurants", "demo", NotificationManager.IMPORTANCE_HIGH);
notificationManager.createNotificationChannel(notificationChannel);
}
notificationManager.notify(id, notificationBuilder.build());
}

How to repeat android notifications after some Interval of hours

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.

Wrong activity when click a notification (PendingIntent)

I implemented a notification service in my android app (FirebaseMessagingService). When I click a notification, and the app is closed, the wrong activity is opened. If the notification arrives while the app is open (foreground, background), the activity that is opened is correct.
In the following code, the splash activity (first activity of the project) is opened instead of IntroNoti.class.
This is the code of my FireBaseMessagingService class
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "FCM Service";
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// TODO: Handle FCM messages here.
// If the application is in the foreground handle both data and notification messages here.
// Also if you intend on generating your own notifications as a result of a received FCM
// message, here is where that should be initiated.
//Log.d(TAG, "From: " + remoteMessage.getFrom());
//Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
Globals.messageIn = true;
sendNotification(remoteMessage);
}
private void sendNotification(RemoteMessage remoteMessage) {
//Intent intent = new Intent(this, Login.class);
Intent intent = new Intent(this, IntroNoti.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_CANCEL_CURRENT);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
int icon = Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP ? R.drawable.ic_launcher: R.mipmap.ic_launcher;
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(icon)
.setContentTitle(remoteMessage.getNotification().getTitle())
.setContentText(remoteMessage.getNotification().getBody())
.setContentText("CIAO CIAO")
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
Thanks to the advice of #Eugen Pechanec I added this instruction in my MainActivity. The "messageid" property is only valued when the app is opened by the notification.
Thank you all!
if (getIntent() != null && getIntent().getExtras() != null && getIntent().getExtras().size() > 0) {
Log.d(TAG, "Received extras in onCreate()");
Bundle extras = getIntent().getExtras();
if (!extras.getString("messageid","").isEmpty()) {
Globals.fromNotification = true;
}
}
Use PendingIntent.FLAG_UPDATE_CURRENT flag with pending intent . It's work for me.
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(getApplication(), CHANNEL_ID)
.setSmallIcon(R.drawable.logo)
.setContentTitle(title)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setCategory(NotificationCompat.CATEGORY_CALL)
.setContentIntent(getPendingIntent())
.setAutoCancel(true);
private PendingIntent getPendingIntent() {
Intent intent = new Intent(getApplication(), ConversationActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
return PendingIntent.getActivity(getApplication(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
}

Non activity class notification not working

I'm trying to make a notification appear in the notification manager from a non activity class, but I can't make it happen
public void showNotification(Context context) {
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(context)
//.setSmallIcon(R.drawable.notif1)
.setContentTitle("Car crash occure!")
.setContentText("Tap to view location.");
PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
new Intent(context, MapsActivity.class), 0);
mBuilder.setContentIntent(contentIntent);
mBuilder.setDefaults(Notification.DEFAULT_SOUND);
mBuilder.setAutoCancel(true);
NotificationManager mNotificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(0, mBuilder.build());
}
Use Intent Service instead of Activity
public static class NotificationActionService extends IntentService {
public NotificationActionService() {
super(NotificationActionService.class.getSimpleName());
}
#Override
protected void onHandleIntent(Intent intent) {
String action = intent.getAction();
if (ACTION_1.equals(action)) {
Log.d("ACTION_NOTIFICATION", "Notification Clicked");
}
// TODO: handle action 1.
// If you want to cancel the notification: NotificationManagerCompat.from(this).cancel(NOTIFICATION_ID);
}
}

Repeating notification sound

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.
