You have to modify the Manifest file as well.

Here is the example that works:

These variables and methods are members of Service class:

public static final String MOVEMENT_UPDATE = "com.client.gaitlink.AccelerationService.action.MOVEMENT_UPDATE"; public static final String ACCELERATION_X = "com.client.gaitlink.AccelerationService.ACCELERATION_X"; public static final String ACCELERATION_Y = "com.client.gaitlink.AccelerationService.ACCELERATION_Y"; public static final String ACCELERATION_Z = "com.client.gaitlink.AccelerationService.ACCELERATION_Z"; private void announceAccelerationChanges()//this method sends broadcast messages { Intent intent = new Intent(MOVEMENT_UPDATE); intent.putExtra(ACCELERATION_X, accelerationX); intent.putExtra(ACCELERATION_Y, accelerationY); intent.putExtra(ACCELERATION_Z, accelerationZ); sendBroadcast(intent); }

And this are the methods from Main activity:

You have to register receiver in the onResume method:

 @Override public void onResume() { IntentFilter movementFilter; movementFilter = new IntentFilter(AccelerationService.MOVEMENT_UPDATE); accelerationReceiver = new AccelerationServiceReceiver(); registerReceiver(accelerationReceiver, movementFilter); startAccelerationService(); super.onResume(); } private void startAccelerationService() { startService(new Intent(this, AccelerationService.class)); } public class AccelerationServiceReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent)//this method receives broadcast messages. Be sure to modify AndroidManifest.xml file in order to enable message receiving { accelerationX = intent.getDoubleExtra(AccelerationService.ACCELERATION_X, 0); accelerationY = intent.getDoubleExtra(AccelerationService.ACCELERATION_Y, 0); accelerationZ = intent.getDoubleExtra(AccelerationService.ACCELERATION_Z, 0); announceSession(); updateGUI(); } }

This is the part of AndroidManifest.xml file that has to be set in order to receive broadcast messages:

<activity android:name=".GaitLink" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> <action android:name="com.client.gaitlink.CommunicationService.action.ACTIVITY_STATUS_UPDATE" /> </intent-filter> </activity>

I have tried this but it is not working as expected .. i have written Log statements but is is not displaying in onRecieve method .what wrong i may be doing i am doing the same as said!
Does the service broadcast the message? Has the BroadcastReceiver been started and running in the activity? Have you added intent filter in AndroidManifest.xml?
i have added BroadcastReceiver in AndroidManifest.xml file , yes the service does the broadcast how can i confirm that the BroadcastReceiver has been started.
Niko, your example is working very well. It was helped me a lot. Thank you very much.
Your code doesn't 100% work, but using broadcasts and BroadcastReceivers was exactly what I wanted to use
