The firebase is working fine , pushing the notification on the status bar but my challange is when the notification is clicked , I want it to take me to my Custom Activity not the default launcher , How do I go about it?
public class CustomActivity extends AppCompatActivity {
private static final String TAG = "CustomActivity";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView mymessage = (TextView) findViewById(R.id.mymessage);
// If a notification message is tapped, any data accompanying the notification
// message is available in the intent extras. In this sample the launcher
// intent is fired when the notification is tapped, so any accompanying data would
// be handled here. If you want a different intent fired, set the click_action
// field of the notification message to the desired intent. The launcher intent
// is used when no click_action is specified.
//
// Handle possible data accompanying notification message.
// [START handle_data_extras]
if (getIntent().getExtras() != null) {
for (String key : getIntent().getExtras().keySet()) {
String value = String.valueOf(getIntent().getExtras().get(key));
Log.d(TAG, "Key: " + key + " Value: " + value);
//
Toast.makeText(getApplicationContext() , value , Toast.LENGTH_SHORT).show();
}
//Toast.makeText(getApplicationContext() , String.valueOf(getIntent().getExtras().get("message")) , Toast.LENGTH_SHORT).show();
}
// [END handle_data_extras]
Button subscribeButton = (Button) findViewById(R.id.subscribeButton);
subscribeButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// [START subscribe_topics]
FirebaseMessaging.getInstance().subscribeToTopic("news");
// [END subscribe_topics]
// Log and toast
String msg = getString(R.string.msg_subscribed);
Log.d(TAG, msg);
Toast.makeText(CustomActivity.this, msg, Toast.LENGTH_SHORT).show();
}
});
Button logTokenButton = (Button) findViewById(R.id.logTokenButton);
logTokenButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Get token
String token = FirebaseInstanceId.getInstance().getToken();
// Log and toast
String msg = getString(R.string.msg_token_fmt, token);
Log.d(TAG, msg);
Toast.makeText(CustomActivity.this, msg, Toast.LENGTH_SHORT).show();
}
});
}
This is my Custom activity that I want to open when the notification is clocked . The Notification is from Firebase cloud messaging.
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "MyFirebaseMsgService";
/**
* Called when message is received.
*
* @param remoteMessage Object representing the message received from Firebase Cloud Messaging.
*/
// [START receive_message]
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// [START_EXCLUDE]
// There are two types of messages data messages and notification messages. Data messages are handled
// here in onMessageReceived whether the app is in the foreground or background. Data messages are the type
// traditionally used with GCM. Notification messages are only received here in onMessageReceived when the app
// is in the foreground. When the app is in the background an automatically generated notification is displayed.
// When the user taps on the notification they are returned to the app. Messages containing both notification
// and data payloads are treated as notification messages. The Firebase console always sends notification
// [END_EXCLUDE]
// TODO(developer): Handle FCM messages here.
Log.d(TAG, "From: " + remoteMessage.getFrom());
// Check if message contains a data payload.
if (remoteMessage.getData().size() > 0) {
Log.d(TAG, "Message data payload: " + remoteMessage.getData());
System.out.print("Message data payload :" + remoteMessage.getData());
}
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
System.out.print("Message Notification Body :" + remoteMessage.getNotification().getBody());
}
// Also if you intend on generating your own notifications as a result of a received FCM
// message, here is where that should be initiated. See sendNotification method below.
}
// [END receive_message]
/**
* Create and show a simple notification containing the received FCM message.
*
* @param messageBody FCM message body received.
*/
private void sendNotification(String messageBody) {
Intent intent = new Intent(this, CustomActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_stat_ic_notification)
.setContentTitle("FCM Message")
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
}
This is the service listening to the Notifications from the firebase.

private void showNotification(String msg) {
//Creating a notification
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setSmallIcon(R.drawable.ic_launcher);
Intent intent = new Intent().setClassName("packagename", "packagename.YourActivityname"); // give any activity name which you want to open
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
builder.setContentIntent(pendingIntent);
builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher));
builder.setContentTitle("FireBase");
builder.setContentText(msg);
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(1, builder.build());
}
I hope it might help you!

Try this
Intent notificationIntent =new Intent(context,ActionActivity.class);
// set intent so it does not start a new activity
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
PendingIntent intent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
this.notification.setLatestEventInfo(context, title, message, intent);
this.notification.flags |= Notification.FLAG_AUTO_CANCEL;
// you can also add other property like vibrate or sound
notificationManager.notify(0, notification);

Inside your FirebaseMessagingService...
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d(TAG, "From: " + remoteMessage.getFrom());
NotificationPublisher.getInstance().showNotification(this, remoteMessage);
}
Then in your NotificationPublisher...
public static final String EXTRA_CHAT_NOTIFICATION = "com.myProject.chat_notification";
public void showNotification(Context context, RemoteMessage remoteMessage) {
Intent intent = new Intent();
if (remoteMessage.getData().get("notification_type") != null) {
Intent i = new Intent("broadCastName");
i.putExtra("type", remoteMessage.getData().get("notification_type"));
i.putExtra("trip_id", remoteMessage.getData().get("trip_id"));
i.putExtra("status", remoteMessage.getData().get("status"));
context.sendBroadcast(i);
return;
}
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent = new Intent(context, MainActivity.class);
HashMap<String, String> dataHash = new HashMap<>(remoteMessage.getData());
intent.putExtra(EXTRA_CHAT_NOTIFICATION, dataHash);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_noti)
.setLargeIcon(R.drawable.ic_noti)
.setColor(ContextCompat.getColor(context, R.color.white))
.setContentTitle(remoteMessage.getData().get("title"))
.setContentText(remoteMessage.getData().get("content"))
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setDefaults(Notification.DEFAULT_VIBRATE)
.setPriority(NotificationCompat.PRIORITY_MAX)
.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
}
}
And finally in your MainActivity onCreate() handle the incoming data...
// Handle possible data accompanying notification message.
// [START handle_data_extras]
if (getIntent().getExtras() != null) {
for (String key : getIntent().getExtras().keySet()) {
Object value = getIntent().getExtras().get(key);
Log.d(TAG, "Key: " + key + " Value: " + value);
if(key.equals(NotificationPublisher.EXTRA_CHAT_NOTIFICATION)) {
// TODO: Start myCustomActivity
}
}
}

I found the answer . Its simple only adding this code on my launcher screen and saving the data as I close the launcher screen and go to the intended activity.
//When Notification is tapped
if (getIntent().getExtras() != null) {
//init message
String message = String.valueOf(getIntent().getExtras().get("message"));
String title = String.valueOf(getIntent().getExtras().get("title"));
//save the message
MySharedPreference.save(getApplicationContext() , "message" , message);
MySharedPreference.save(getApplicationContext() , "title" , title);
startActivity(new Intent(getApplicationContext() , MainActivity.class));
finish();
}
