Im developing a C2DM Messaging application. In that i order to receive the registration id im using the C2DMBroadcastReceiver, C2DMBaseReceiver and C2DMMessaging class. I will be C2DMReceiver in my package which extends the C2DMBaseReceiver.
Here is my code snippet
C2DMMessaging.java
package com.google.android.c2dm;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.util.Log;
public class C2DMessaging {
public static final String EXTRA_SENDER = "sender";
public static final String EXTRA_APPLICATION_PENDING_INTENT = "app";
public static final String REQUEST_UNREGISTRATION_INTENT = "com.google.android.c2dm.intent.UNREGISTER";
public static final String REQUEST_REGISTRATION_INTENT = "com.google.android.c2dm.intent.REGISTER";
public static final String LAST_REGISTRATION_CHANGE = "last_registration_change";
public static final String BACKOFF = "backoff";
public static final String GSF_PACKAGE = "com.google.android.gsf";
// package
static final String PREFERENCE = "com.google.android.c2dm";
private static final long DEFAULT_BACKOFF = 30000;
/**
* Initiate c2d messaging registration for the current application
*/
public static void register(Context context,
String senderId) {
Intent registrationIntent = new Intent(REQUEST_REGISTRATION_INTENT);
registrationIntent.setPackage(GSF_PACKAGE);
registrationIntent.putExtra(EXTRA_APPLICATION_PENDING_INTENT,
PendingIntent.getBroadcast(context, 0, new Intent(), 0));
registrationIntent.putExtra(EXTRA_SENDER, senderId);
context.startService(registrationIntent);
Log.e("C2DM Services","Service Started");
}
/**
* Unregister the application. New messages will be blocked by server.
*/
public static void unregister(Context context) {
Intent regIntent = new Intent(REQUEST_UNREGISTRATION_INTENT);
regIntent.setPackage(GSF_PACKAGE);
regIntent.putExtra(EXTRA_APPLICATION_PENDING_INTENT, PendingIntent.getBroadcast(context,
0, new Intent(), 0));
context.startService(regIntent);
Log.e("C2DM Services","unregister");
}
/**
* Return the current registration id.
*
* If result is empty, the registration has failed.
*
* @return registration id, or empty string if the registration is not complete.
*/
public static String getRegistrationId(Context context) {
final SharedPreferences prefs = context.getSharedPreferences(
PREFERENCE,
Context.MODE_PRIVATE);
String registrationId = prefs.getString("dm_registration", "");
Log.e("C2DM Services","get registration id");
return registrationId;
}
public static long getLastRegistrationChange(Context context) {
final SharedPreferences prefs = context.getSharedPreferences(
PREFERENCE,
Context.MODE_PRIVATE);
Log.e("C2DM Services","getlastregchange");
return prefs.getLong(LAST_REGISTRATION_CHANGE, 0);
}
static long getBackoff(Context context) {
final SharedPreferences prefs = context.getSharedPreferences(
PREFERENCE,
Context.MODE_PRIVATE);
Log.e("C2DM Services","getbackoff");
return prefs.getLong(BACKOFF, DEFAULT_BACKOFF);
}
static void setBackoff(Context context, long backoff) {
final SharedPreferences prefs = context.getSharedPreferences(
PREFERENCE,
Context.MODE_PRIVATE);
Editor editor = prefs.edit();
editor.putLong(BACKOFF, backoff);
editor.commit();
Log.e("C2DM Services","setbackoff");
}
// package
static void clearRegistrationId(Context context) {
final SharedPreferences prefs = context.getSharedPreferences(
PREFERENCE,
Context.MODE_PRIVATE);
Editor editor = prefs.edit();
editor.putString("dm_registration", "");
editor.putLong(LAST_REGISTRATION_CHANGE, System.currentTimeMillis());
editor.commit();
Log.e("C2DM Services","clearregid");
}
// package

PREFERENCE,
Context.MODE_PRIVATE);
Editor editor = prefs.edit();
editor.putString("dm_registration", registrationId);
editor.commit();
Log.e("C2DM Services","setregid");
}
}

Now my problem is,
I calling the Register of the C2DMMessaging from my activity by passing the context, The service is created in the C2DMMessaging, After that im not receiving anything in the C2DMBroadcastReceiver’s onReceive().
This is the code i got from vogille.de. This is working fine if i use this as such but when im using this in my application this problem is coming.
I have gone thro’ some post n googled something in which i found that the problem may be in manifest file.
i don know where im wrong. Can anyone help on this?
For an obscure reason, your receiver class, C2DMReceiver, has to be in the root of your package, which is declared as your package name in your manifest.
This is the only way i managed to get this working… so instead of :
try
here is my manifest excerpt (except the permissions)
