Bugfix for copying assets using v0.3 of the Android Gradle build system. This allows assets to be recursively copied into the APK.

build.gradle

task copyAssetsRec {
  description 'Temporary fix to recursively add folders and files from assets. Remove in v0.4.'

  ext.assetsSrcDir = file( "${projectDir}/src/main/assets" )
  ext.assetsBuildDir = file( "${buildDir}/assets" )

  inputs.dir assetsSrcDir
  outputs.dir assetsBuildDir

  doLast {
    android.buildVariants.each { target ->
      copy {
        from assetsSrcDir
        into "${assetsBuildDir}/${target.dirName}"
      }
    }
  }
}

copyAssetsRec.dependsOn {
  tasks.matching { task -> task.name.startsWith( 'merge' ) && task.name.endsWith( 'Assets' ) }
}

tasks.withType( Compile ) {
  compileTask -> compileTask.dependsOn copyAssetsRec
}
