I have one project as a library of another one because I need whitelabeling it (and more projects for other partners). In the library project, I have implemented push notifications system. I've executed the library project as a normal project and the pushs work like a charm. My problem happens when i am importing this project as a library in another project. The receiver is never called.
There is one post with the same issue but the solution is not working for me. I am getting crazy!!!
Android C2DM and lib project
The main problem is that I am not receiving the message from C2DM. My code is the next:
Manifests of the both project (I have the same piece of code in both projects) (I am using the tags lib_project and app_project to be clear):
<receiver
android:name="com.lib_project.C2DMBroadcastReceiver"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="com.app_project.android" />
</intent-filter>
<intent-filter>
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<category android:name="com.app_project.android" />
</intent-filter>
</receiver>
And the permissions:
<uses-permission android:name="com.app_project.android.permission.C2D_MESSAGE" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<permission
android:name="com.app_project.android.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
And also I have declared in the manifest the service that manage the push notifications but it is called properly.
<service android:name="com.lib_project.android.C2DMReceiver" />
Really, I don't know what is wrong. I think is ok but is not working. Thanks in advance.
