I followed this tutorial: http://www.androidhive.info/2012/10/android-push-notifications-using-google-cloud-messaging-gcm-php-and-mysql/#comment-2952759611
I am able to send Firebase notifications to an Android app.
My class which extends the Firebase messaging service is
public class MyFirebaseMessagingService extends FirebaseMessagingService {
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
if (remoteMessage.getNotification() != null) {
String notificationTitle = remoteMessage.getNotification().getTitle();
String notificationBody = remoteMessage.getNotification().getBody();
handleNotification(notificationTitle, notificationBody);
}
private void handleNotification(String title, String body) {
if (!NotificationUtils.isAppIsInBackground(getApplicationContext())) {
// app is in foreground, broadcast the push message
Intent pushNotification = new Intent(Config.PUSH_NOTIFICATION);
pushNotification.putExtra("title", title);
pushNotification.putExtra("message", body);
LocalBroadcastManager.getInstance(this).sendBroadcast(pushNotification);
} else {
// If the app is in background, firebase itself handles the notification
}
}
}
In one of my activities I have a listener defined and all other activities extend this class
public class DisplayNotificationActivity extends AppCompatActivity {
private BroadcastReceiver mRegistrationBroadcastReceiver;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_display_notification);
mRegistrationBroadcastReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
// process notification
}
}
}
}
An example of a class which extends DisplayNotificationActivity is:
public class ListNotificationsActivity extends DisplayNotificationActivity {
private BroadcastReceiver mRegistrationBroadcastReceiver;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list_notifications);
mRegistrationBroadcastReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
// process notification
}
};
}
}
If I am on the DisplayNotificationActivity activity when I receive a notification everything works as expected, but if I am on another activity such as ListNotificationsActivity then the DisplayNotificationActivity onCreate method is called, not the onCreate in the active activity.
How do I have the current activity handle the receiving of a notification on any activity without repeating the same code in all activities?
Edit: I do pause and resume the activity, this code is in DisplayNotificationActivity
#Override
protected void onResume() {
super.onResume();
LocalBroadcastManager.getInstance(this).registerReceiver(mRegistrationBroadcastReceiver,
new IntentFilter(Config.REGISTRATION_COMPLETE));
LocalBroadcastManager.getInstance(this).registerReceiver(mRegistrationBroadcastReceiver,
new IntentFilter(Config.PUSH_NOTIFICATION));
NotificationUtils.clearNotifications(getApplicationContext());
}
#Override
protected void onPause() {
LocalBroadcastManager.getInstance(this).unregisterReceiver(mRegistrationBroadcastReceiver);
super.onPause();
}
Your activity DisplayNotificationActivity is super class for activity ListNotificationsActivity and you have called super.onCreate() method in ListNotificationsActivity that definitely will call super method onCreate of your super class i.e. DisplayNotificationActivity.
Now for solution what you can do is use interface:
public abstract class DisplayNotificationActivity extends AppCompatActivity {
private BroadcastReceiver mRegistrationBroadcastReceiver;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_display_notification);
mRegistrationBroadcastReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
// process notification
onNotificationReceived(your notification message);
}
}
}
public void onNotificationRecieved(String notiMessage);
}
And on your ListNotificationsActivity :
public class ListNotificationsActivity extends DisplayNotificationActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list_notifications);
}
#Override
public void onNotificationRecieved(String notiMessage) {
//process your notification
}
}
I have not run the code see if this works.

I am using a LocalBroadcastManager to make broadcast to my activtiy and services using APPLICATION CONTEXT , like this:
public class CommonForApp extends Application{
public void broadcastUpdateUICommand(String[] updateFlags,
String[] flagValues) {
Intent intent = new Intent(UPDATE_UI_BROADCAST);
for (int i = 0; i < updateFlags.length; i++) {
intent.putExtra(updateFlags[i], flagValues[i]);
}
mLocalBroadcastManager = LocalBroadcastManager.getInstance(mContext);
mLocalBroadcastManager.sendBroadcast(intent);
}}
Now Using a Listener in my Service, I am calling broadcastUpdateUICommand() ,like this:
public class mService extends Service {
public BuildNowPLaylistListListener buildCursorListener = new BuildNowPLaylistListListener() {
#Override
public void onServiceListReady() {
mApp.broadcastUpdateUICommand(
new String[] { CommonForApp.INIT_DRAWER},
new String[] {""});
}}}
And i am receiving the broadcast in my Activity, like this:
public class mActivity extends Activity{
BroadcastReceiver mReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
mtoast.showtext("in onreceive"); //toast to check
if (intent.hasExtra(CommonForApp.INIT_DRAWER))
initialiseDrawer();
}};
}
mApp is instance of Application.
CommonForApp is my Application Class.
But in my activity i am not receving any broadcast(the broadcast manager is initialised using application context) .
Can Anyone suggest me why i am not receiving broadcast in my activity? ..
.Thanks in advance !
in activity:
protected BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, final Intent intent) {
runOnUiThread(new Runnable() {
#Override
public void run() {
if(intent.hasExtra("type")){
// Do some action
}
}
});
}
};
#Override
public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
super.onCreate(savedInstanceState, persistentState);
LocalBroadcastManager.getInstance(this).registerReceiver(mMessageReceiver,
new IntentFilter("data-loaded"));
}
protected void onDestroy() {
super.onDestroy();
LocalBroadcastManager.getInstance(this).unregisterReceiver(mMessageReceiver);
}
then you send broadcast:
public static void sendBroadcastMessageDataLoaded(Context context, String dataType){
Intent intent = new Intent("data-loaded");
intent.putExtra("type", dataType);
LocalBroadcastManager.getInstance(context).sendBroadcast(intent);
}
myButton is a button that when clicked is supposed to receive a broadcast from a background IntentService. But the broadcast is never received. However if I move the broadcastReceiver outside of myButton.setOnClickListener function, then I begin to receive broadcasts from my background service.
Is there a way to make the broadcastReceiver receive broadcasts within the setOnClickListener function?
public class MainActivity extends Activity {
private BroadcastReceiver broadcastReceiver;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
myButton = (Button)findViewById(R.id.button1);
myButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
broadcastReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context arg0, Intent intent) {
Toast.makeText(MainActivity.this, "BROADCAST RECEIVED", Toast.LENGTH_SHORT).show();
stopService(msgIntent);
}
};
}
});
public void onResume()
{
super.onResume();
IntentFilter filter = new IntentFilter(SimpleIntentService.ACTION_RESP);
filter.addCategory(Intent.CATEGORY_DEFAULT);
registerReceiver(broadcastReceiver,filter);
}
public void onPause()
{
unregisterReceiver(broadcastReceiver);
super.onPause();
}
}
I had to take out the broadcastReceiver from onClick method. This works and broadcast is received:
public class MainActivity extends Activity {
private BroadcastReceiver broadcastReceiver;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
myButton = (Button)findViewById(R.id.button1);
myButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
//do extra stuff
}
});
broadcastReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context arg0, Intent intent) {
Toast.makeText(MainActivity.this, "BROADCAST RECEIVED", Toast.LENGTH_SHORT).show();
stopService(msgIntent);
}
};
}
}
Do you forget to registerReceiver?
You might also need to assign a IntentFilter when you register a receiver.
The following is some sample codes from my project:
private class LocationInfoReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// do something
}
}
locationInfoReceiver = new LocationInfoReceiver();
// the key you use setAction() method in your Intent Service
IntentFilter locationInfoReceiverFilter = new IntentFilter("your key");
locationInfoReceiverFilter.addCategory(Intent.CATEGORY_DEFAULT);
registerReceiver(locationInfoReceiver, locationInfoReceiverFilter);
Store Activity:
public void unlockcup2(){
}
Main Activity:
public void unlock2(){
x = (x-100);
ImageView img5 = (ImageView) findViewById(R.id.bluecake);
img5.setVisibility(View.VISIBLE);
}
Soo, I want to make it so when my button in Store activity(Witch calls unlockcup2()) Call unlock2 in my MainActivity . How do I do this?
localbroadcastmanager can do this job. Send a broadcast in the StoreActivity and receive it in the MainActivity and call unlock2()
MainActivity (Receiver)
private BroadcastReceiver mReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
// in this case, there's only one type of action, so no need to check action
unlock2();
}
};
#Override
public void onCreate(Bundle savedInstanceState) {
...
LocalBroadcastManager.getInstance(this).registerReceiver(mReceiver,
new IntentFilter("custom-action-name"));
}
#Override
protected void onDestroy() {
...
LocalBroadcastManager.getInstance(this).unregisterReceiver(mReceiver);
}
StoreActivity (Sender)
public void unlockcup2() {
...
LocalBroadcastManager.getInstance(this)
.sendBroadcast(new Intent("custom-action-name"));
}
I Have three activities
On activity A i register the broadcast receiver ,then i go to activity B from there i go to activity C.
and finally onBackPressed of activity c ,i send the broadcast
but onReceive is not called
My first Activity
private MyBroadCastReceiver myRecevier = new MyBroadCastReceiver();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Submit.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent frag=new Intent(MainActivity.this,Activity2.class);
//frag.putExtra("Limit", foo);
startActivity(frag);
// }
}
});
}
#Override
protected void onResume() {
super.onResume();
//Register the activity to the broadcast receiver
registerReceiver(myRecevier, new IntentFilter(MyBroadCastReceiver.ACTION));
}
#Override
protected void onPause() {
super.onPause();
//Unregister the activity from the broadcast receiver. Good practice ;)
unregisterReceiver(myRecevier);
}
public class MyBroadCastReceiver extends BroadcastReceiver{
public static final String ACTION = "com.uberrueco.mybroadcastreceiver.receivers";
#Override
public void onReceive(Context context, Intent intent) {
Log.d("MyBroadCastReceiver", "received");
Toast.makeText(context,"Received "+intent.getStringExtra("editText"), Toast.LENGTH_LONG).show();
}
}
}
Second activity has nothing but an intent to activity 3
Third Activity
public class Activity3 extends Activity {
EditText etReceivedBroadcast;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity3);
etReceivedBroadcast = (EditText) findViewById(R.id.etReceivedBroadcast);
}
#Override
public void onBackPressed() {
// TODO Auto-generated method stub
super.onBackPressed();
Intent intent = new Intent(this, MyIntentService.class);
intent.putExtra("editText", etReceivedBroadcast.getText().toString());
startService(intent);
}
}
and finally my IntentService class
public class MyIntentService extends IntentService{
public MyIntentService(){
super("MyIntentService");
}
public MyIntentService(String name) {
super(name);
}
#Override
protected void onHandleIntent(Intent intent) {
Log.d("MyIntentService", "handling intent...");
//Intent created for broadcasting
Intent intentBroadCast = new Intent();
//Filter the broadcast to the action desired
intentBroadCast.setAction(MyBroadCastReceiver.ACTION);
intentBroadCast.putExtra("editText", intent.getStringExtra("editText"));
//Send the broadcast :D
sendBroadcast(intentBroadCast);
}
}
You are calling unregisterReceiver in onPause of MainActivity . So you are not recieving the broadcast.
Move register to onCreate and unregister to onDestroy of your MainActivity.
if your onHandleIntent() was called then you should try like.
Intent intentBroadCast = new Intent(MyBroadCastReceiver.ACTION);
intentBroadCast.putExtra("editText", intent.getStringExtra("editText"));
//Send the broadcast :D
sendBroadcast(intentBroadCast);
make changes like below code
private MyBroadCastReceiver myRecevier = new MyBroadCastReceiver();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Register the activity to the broadcast receiver
this.registerReceiver(myRecevier, new IntentFilter(MyBroadCastReceiver.ACTION));
Submit.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent frag=new Intent(MainActivity.this,Activity2.class);
//frag.putExtra("Limit", foo);
startActivity(frag);
// }
}
});
}
#Override
protected void onResume() {
super.onResume();
}
#Override
protected void onDestroy() {
super.onDestroy();
//Unregister the activity from the broadcast receiver. Good practice ;)
this.unregisterReceiver(myRecevier);
}
#Override
protected void onPause() {
super.onPause();
//Unregister the activity from the broadcast receiver. Good practice ;)
unregisterReceiver(myRecevier);
}
public class MyBroadCastReceiver extends BroadcastReceiver{
public static final String ACTION = "com.uberrueco.mybroadcastreceiver.receivers";
#Override
public void onReceive(Context context, Intent intent) {
Log.d("MyBroadCastReceiver", "received");
Toast.makeText(context,"Received "+intent.getStringExtra("editText"), Toast.LENGTH_LONG).show();
}
}
}
u need to use like this this.unregisterReceiver() and this.registerReceiver()
In my Application I have to notify my Activity from IntentService class .
For that purpose I am using LocalBroadcastManager. But I am not receiving anything in the onReceive of my Broadcast Receiver. Here is what I have written.
In my BaseActivity I have registered my receiver.
public class BaseActivity extends FragmentActivity implements App {
#Override
protected void onCreate(Bundle arg0) {
super.onCreate(arg0);
}
#Override
protected void onResume() {
super.onResume();
LocalBroadcastManager.getInstance(this).registerReceiver(
mMessageReceiver, new IntentFilter(custom-event-name));
}
#Override
protected void onPause() {
super.onPause();
LocalBroadcastManager.getInstance(this).unregisterReceiver(
mMessageReceiver);
}
// Our handler for received Intents. This will be called whenever an Intent
// with an action named "custom-event-name" is broadcasted.
BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
Bundle bundle = intent.getExtras();
System.out.println("Overlay Message" +bundle.getString("message"));
}
};
}
I am sending a local broadcast from my RegisterAlarmIntentService class.
public class RegisterAlramIntentService extends WakefulIntentService implements
APIConstants {
public RegisterAlramIntentService() {
super("AlarmService");
}
#Override
public String getTag() {
return "AlarmService";
}
#Override
protected void onHandleIntent(Intent intent) {
System.out.println("Working till here fine In RegisterAlarm");
Bundle bundle = intent.getExtras();
Intent localIntent = new Intent(custom-event-name);
localIntent.putExtras(bundle );
LocalBroadcastManager.getInstance(this).sendBroadcast(
localIntent);
}
}
onHandleIntent() method is called. But nothing is received in onReceive() of my receiver.
Please Help. Thanks in advance!!
Try
public class RegisterAlramIntentService extends WakefulIntentService implements
APIConstants {
Intent localIntent;
public RegisterAlramIntentService() {
super("AlarmService");
localIntent = new Intent(custom-event-name);
}
#Override
public String getTag() {
return "AlarmService";
}
#Override
protected void onHandleIntent(Intent intent) {
System.out.println("Working till here fine In RegisterAlarm");
Bundle bundle = intent.getExtras();
Thread.sleep(5000); // For Testing only because it is in whole new thread (which may not wait for your reciever to setup)
localIntent.putExtras(bundle );
LocalBroadcastManager.getInstance(this).sendBroadcast(
localIntent);
}
}
Also in manifest :
<service android:name="com.commonsware.android.localcast.RegisterAlramIntentService"/>
