I followed the same steps that are mentioned in the "Android Cloud to Device Messaging (C2DM) - Tutorial", downloading the source code for the project and customizing it for my purpose (changing the package name and role e-mail sender).
Unfortunately I get an error message stating:
"Unable to start service Intent
{act=com.google.android.c2dm.intent.REGISTER ... }: not found" in logcat.
Knowing that I have added a Google account to the emulator which is different than the one I used when signing up on the service in the first place.
Can anyone provide help or direction in how can I get the registeration key correctly setup and solve this problem?
I think I figure the solution for my above question which is, you have to create new AVD using android AVD manager that its target Google APIs either level 8 or 15 or whatever, not using android API. and also you have to have google account that added to your emulator which is the role e-mail that you used in development process of your application.
I hope that solve all problems faced other developers regarding this issue.
