问题
I have a problem when I try to add GCM in my application, when the package name starts with capital letter.
The problem is in the code:
<permission android:name="Myapplication.com.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
When you try to install it in the emulator the output is:
install_parse_failed_manifest_malformed
If you are starting a new application you can solve it changing the package name from "Myapplication.com" to "myapplication.com" (little letters), but if you're updating an already existing application you cannot do that, because Google Play does not admit the change of the package name when updating.
