新的Android Gradle Build System构建配置包名称与Provider Authority的冲突

Question

I've updated my project to use the new Gradle based build system, largely because I've been kind of annoyed that I can't have my app installed on my device to use it since I use the device for development. I saw a lot of promise in the packageNameSuffix offering of the new build system.

The problem that I'm running into involves things other than the package name in the manifest. There are other parts that have to be unique, including permissions (specifically for GCM) and ContentProvider Authorities. When trying to install with a .debug suffix I get errors that the GCM permission for that package hasn't been defined and that I'm trying to install a duplicate provider.

Is there a variable that I can put in my manifest instead of these strings so that the build system will replace those appropriately as well?

Answer 1

Here is my solution for GCM problems with packageNameSuffix.

Primary problem is permission names that should have ".debug" suffix. I put that permission to debug and release manifests that are merged to final manifest.

Answer 2

This is a current known limitation of changing the package name for a variant. I'm planning on fixing this as soon as possible.

Answer 3

I've replaced all my app's package name in AndroidManifest.xml with placeholder ${packageName}, so Manifest Merger does all work

For example:

<uses-permission android:name="${packageName}.permission.C2D_MESSAGE" />

Answer 4

You can use:

<permission android:name=".permission.C2D_MESSAGE"
            android:protectionLevel="signature" />
<uses-permission android:name=".permission.C2D_MESSAGE" />

Android will add the current package name automatically, as you started with a . .
