Overriding GCM permission package prefix with Gradle

Question

I have a Gradle Android project that has 4 product flavors (each has it's own unique package name). The build.gradle file is prity much straightforward:

buildscript {     repositories {         mavenCentral()     }      dependencies {         classpath 'com.android.tools.build:gradle:0.6.+'     } }  apply plugin: 'android'  repositories {     mavenCentral() }  dependencies {     // All dependencies here     // ... }  android {     // Usual stuff goes here      productFlavors {         flav1 {             packageName 'com.company.flav1'             versionName calcVersion()         }          flav2 {             packageName 'com.company.flav2'             versionName calcVersion()         }          flav3 {             packageName 'com.company.flav3'             versionName calcVersion()         }          flav4 {             packageName 'com.company.flav4'             versionName calcVersion()         }     }      // Other configurations     // ... } 

Everything goes fine, and the required resources are merged, e.t.c. Now I am trying to implement a Push Notification feature using GCM. And according to the documentation, I must declare a permission for my app, like this:

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

But I'm using a single manifest file, for all 4 applications (they differ only in application resources and some settings, that are put in the assets folder).

So my question is: How can I override these permissions for every product flavor?

Answer 1

I've used:

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

in the Android manifest - this appears to be resolved correctly.

Answer 2

You can use some sort of inheritance AndroidManifest.

The following rules are used when dealing with all the sourcesets used to build a single APK:   - All source code (src/*/java) are used together as multiple folders generating a single output.  - *Manifests are all merged together into a single manifest. This allows Product Flavors to have different components and/or permissions, similarly to Build Types.*  - All resources (Android res and assets) are used using overlay priority where the Build Type overrides the Product Flavor, which overrides the main sourceSet.  - Each Build Variant generates its own R class (or other generated source code) from the resources. Nothing is shared between variants. 

code:

  productFlavors {         flav1 {             packageName 'com.company.flav1'             versionName calcVersion()         }          flav2 {             packageName 'com.company.flav2'             versionName calcVersion()         }          flav3 {             packageName 'com.company.flav3'             versionName calcVersion()         }          flav4 {             packageName 'com.company.flav4'             versionName calcVersion()         }     }    sourceSets {         main {             manifest.srcFile 'AndroidManifest.xml'             java.srcDirs = ['src']             resources.srcDirs = ['src']             aild.srcDirs = ['src']             renderscript.srcDirs = ['src']             res.srcDirs = ['res']             assets.srcDirs = ['assets']         }          flav1 {             manifest.srcFile 'flavor1/AndroidManifest.xml'         }          flav2 {             manifest.srcFile 'flavor2/AndroidManifest.xml'         }          ...     } 

Where flavor1 and flavor2 are folders in root project folder.

In flavor1/AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"       package="com.sample.someapp"       android:versionCode="1"       android:versionName="1.0">  <permission android:name="com.company.flav1.permission.C2D_MESSAGE"         android:protectionLevel="signature" /> <uses-permission android:name="com.company.flav1.permission.C2D_MESSAGE" />    </manifest> 

In flavor2/AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"       package="com.sample.someapp"       android:versionCode="1"       android:versionName="1.0">  <permission android:name="com.company.flav2.permission.C2D_MESSAGE"         android:protectionLevel="signature" /> <uses-permission android:name="com.company.flav2.permission.C2D_MESSAGE" />    </manifest> 

And in root AndroidManifest everything else.
