android - unable to receive broadcast from a background service

I was working with broadcast receiver and background services. So, When one my activity goes onPause(), I start my service and service sends a broadcast. Now, my broadcast receiver is in the same class as my service. I am receiving my service call, but I am unable to receive the broadcast info. Here is the code I have been working on..
[EDITED]
private String notifier = "ninja.ibtehaz.thenewproject.Activities.activityNew";
#Override
protected void onHandleIntent(Intent intent) {
boolean flag = ProjectApp.getInstance().isActivityVisible();
Log.e("rainbow", "onHandleIntent");
if (!flag) {
//start emergency activity
Log.e("rainbow", "starting activity");
Intent broadcastIntent = new Intent(notifier);
sendBroadcast(broadcastIntent);
}
}
[EDITED] on activityNew class >
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.e("rainbow", "In Method: Service started");
IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
filter.addAction(Intent.ACTION_SCREEN_OFF);
registerReceiver(receiver, filter);
}
private BroadcastReceiver receiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
Log.e("rainbow", "In Method: onReceive");
if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
Log.e("rainbow","Screen went OFF");
}
if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
Log.e("rainbow","Screen went ON");
}
}
};
and the manifest file : [EDITED]
<service android:name=".Activities.ServiceBackground">
</service>
<receiver
android:name=".Activities.ActivityEmergency"
android:theme="#android:style/Theme.NoDisplay">
</receiver>
here is my logcat info :
E/rainbow: onHandleIntent
E/rainbow: starting activity
I am not getting anything after that..
I know this might not be the best practice, I just started working with these things.
Thank you for your help. Cheers!

You are registering a BroadcastReceiver with an IntentFilter which only contains Intent.ACTION_SCREEN_OFF and Intent.ACTION_SCREEN_ON, but no ninja.ibtehaz.thenewproject.Activities.activityNew. It means this BroadcastReceiver can only be invoked when Intent.ACTION_SCREEN_OFF or Intent.ACTION_SCREEN_OFF is broadcast.
Now pay attention to your sendBroadcast code:
Intent broadcastIntent = new Intent(notifier);
sendBroadcast(broadcastIntent);
You are broadcasting an action "ninja.ibtehaz.thenewproject.Activities.activityNew", which can't match the IntentFilter bound with the BroadcastReceiver you have registered.
Try to use these codes:
IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
filter.addAction(Intent.ACTION_SCREEN_OFF);
filter.addAction(notifier);
registerReceiver(receiver, filter);

Broadcast Limitations : With limited exceptions, apps cannot use their manifest to register for implicit broadcasts. They can still register for these broadcasts at runtime, and they can use the manifest to register for explicit broadcasts targeted specifically at their app.
Android documentation: https://developer.android.com/about/versions/oreo/background
Try registering like below dynamically in Application Activity/Service instead of Manifest.
BroadcastReceiver receiver = new NotificationReceiver();
IntentFilter filter = new IntentFilter();
filter.addAction(ACTION_UPDATE_NOW);
context.registerReceiver(receiver, filter);

You are registering your receiver inside the processing an intent method ;-) This would not work, definitely.
You must register your receiver earlier, ex. in onCreate() method.

My Broadcast Receiver class not gets called

I am trying to start an intent service from one activity which gets data from server and try to get that data in another activity using broadcast receiver but the broadcast receiver class is not getting called, I have registered my service class in manifest also
Here is my code to start a service
Intent intent = new Intent(LoginActivity.this, MyWebRequestService.class);
startService(intent);
Class MyWebRequestService
//inside on handle intent
new AsynchCall().execute();
Intent broadcastIntent = new Intent();
broadcastIntent.setAction(MyWebRequestReceiver.PROCESS_RESPONSE);
broadcastIntent.addCategory(Intent.CATEGORY_DEFAULT);
//here I am getting the data in my arraylist
broadcastIntent.putStringArrayListExtra("namelist", servicelist);
sendBroadcast(broadcastIntent);
Activity where I want to receive my data
IntentFilter filter =IntentFilter(MyWebRequestReceiver.PROCESS_RESPONSE);
filter.addCategory(Intent.CATEGORY_DEFAULT);
receiver = new MyWebRequestReceiver();
registerReceiver(receiver, filter);
In the same activity I have written my broadcast receiver class
public class MyWebRequestReceiver extends BroadcastReceiver
{
public static final String PROCESS_RESPONS = "com.rentpro.PROCESS_RESPONSE";
#Override
public void onReceive(Context context, Intent intent)
{
listofnames = intent.getStringArrayListExtra("namelist");
}
}

Make sure that the receiver
registerReceiver(receiver, filter);
is called before sending the broadcast
sendBroadcast(broadcastIntent);

Broadcast reciever not working from service

I am trying to use BroadcastReceiver inside my service but it is not working properly.
I am starting my service in an onCreate in my activity. Then in the services onCreate I am calling the following to register the Broadcast reciever:
IntentFilter filter = new IntentFilter();
registerReceiver(DataUpdateReceiver, filter);
Here's the broadcast receiver i am trying to register:
private BroadcastReceiver DataUpdateReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Test", Toast.LENGTH_LONG).show();
}
};
Then else where in the Activity I am trying to call this so therefor the Toast message will be displayed.
Intent i = new Intent();
sendBroadcast(i);
But the Toast is not being displayed, I have also tried logging but nothing shows up. If anyone could help me out on this it would be appreciated, ty.

In my opinion, you have to specify action (or actions), which fire onReceive() method. Something like this might help you:
IntentFilter filter = new IntentFilter("some_action");
registerReceiver(DataUpdateReceiver, filter);
...
Intent i = new Intent("some_action");
sendBroadcast(i);

Declare on top of the class
public final static String MY_RECEIVER_START = "com.yourcompanyname.appname.MY_RECEIVER_START";
private Radio radio;
In the service constructor
//Initiate our receiver
radio = new Radio();
//Activate our recevier
context.registerReceiver(radio, new IntentFilter(MY_RECEIVER_START));
Also in the service, create the receiver class and the method which shows toast
/**
* Receiver Class
* This setup checks for the incoming intent action to be able to
* attach more messages to one receiver.
*/
private class Radio extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(MY_RECEIVER_START)){
//show toast
}
}
}
After from anywhere in the application send message to our radio
context.sendBroadcast(new Intent("com.yourcompanyname.appname.MY_RECEIVER_START"));

addAction() & Service calling Dilemma

I'm stuck here at my previous struggle >> Prev. Struggle!
Raanan there helped! me a lot but then he I think went away as timing zone is different , now I'm stuck with my service code that I'm using to call my BroadcastReceiver() that is in the activity! and also I'm not getting with what parameter I should load the filter.addAction(action); in place of action??
Kinldy guide me!
CODE in the Server:
Toast.makeText(Server.this, hr +" , " +min, Toast.LENGTH_LONG).show();
Intent intent = new Intent(this, andRHOME.class);
//intent.putExtra("sendMessage","1");
sendBroadcast(intent);
and CODE IN THE ACITIVITY(Broadcast Receiver)
private BroadcastReceiver ReceivefrmSERVICE = new BroadcastReceiver(){
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "IN DA BroadCASTER",
Toast.LENGTH_LONG).show();
sendMessage("1");
}
};
IntentFilter filter = new IntentFilter();

You need to add these line to regiester your receiver for some action for example define a Global variable like this:
public static String NOTIFCATION_BROADCAST_ACTION = "com.your_packagename.UPDATE_NOTIFICATION_INTENT";
then register the action like this in your activity onCreate() Method.
IntentFilter filter = new IntentFilter();
filter.addAction(Global.NOTIFCATION_BROADCAST_ACTION);
registerReceiver(ReceivefrmSERVICE, filter);
Then send the broadcast from your service like this
Intent broadcast = new Intent();
broadcast.setAction(Global.NOTIFCATION_BROADCAST_ACTION);
sendBroadcast(broadcast);
Then in your broadcast Receiver filter this action like this
private BroadcastReceiver ReceivefrmSERVICE = new BroadcastReceiver(){
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Global.NOTIFCATION_BROADCAST_ACTION)) {
//Do your stuff here :)
}
}
};

Android - Registering a broadcast receiver for two intents?

I was wondering is it possible to register a broadcast receiver to receive two intents?
My code is as follows:
sipRegistrationListener = new BroadcastReceiver(){
#Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (SIPEngine.SIP_REGISTERED_INTENT.equals(action)){
Log.d("SETTINGS ", "Got REGISTERED action");
}
if (SIPEngine.SIP_UNREGISTERED_INTENT.equals(action)){
Log.d("SETTINGS ", "Got UNREGISTERED action");
}
}
};
context.registerReceiver(sipRegistrationListener, new IntentFilter(SIPEngine.SIP_REGISTERED_INTENT));
context.registerReceiver(sipRegistrationListener, new IntentFilter(SIPEngine.SIP_UNREGISTERED_INTENT));
I get the REGISTERED Intent everytime I send it but I never get the UNREGISTERED Intent when I send it.
Should I set up another Broadcast receiver for the UNREGISTERED Intent?

Don't create your IntentFilter inline, then use the addAction method to add the UNREGISTERED action, i.e.:
IntentFilter filter = new IntentFilter(SIPEngine.SIP_REGISTERED_INTENT);
filter.addAction(SIPEngine.SIP_UNREGISTERED_INTENT);
context.registerReceiver(sipRegistrationListener, filter);
