Android Studio 1.0 and error “Library projects cannot set applicationId”

Question

After updating Android Studio to 1.0, I see this error:

Error: Library projects cannot set applicationId. applicationId is set to \'com

Answer 1

You cannot define applicationId for your lib. But incase you want to use an identifier in your build file, which will give you, your library package name, you can define a variable for the module and then use the value as required.

eg : Library's build.gradle

apply plugin: 'com.android.library'

def libraryGroupId = 'com.google.example'
def libraryArtifactId = project.getName()
def libraryVersion = '1.1'

Also, you can use the value below as needed in your build file itself in lib.

android {
compileSdkVersion 28

defaultConfig {
    minSdkVersion 21
    targetSdkVersion 28
    versionCode 1
    versionName "$libraryVersion"
    resValue "string", "Library", libraryGroupId"
 }
}
