解决Android Studio中Gradle错误“属性“ xxx”已定义”的有效方法？

Question

In my project, i have a module abc :

//abc module (lib) dependency
dependencies {
     compile 'com.android.support:support-v4:21.0.3'
}

And my app's dependency:

dependencies {
      compile project(':abc')
}

And the errors are:

“Attribute ”mnp“ has already been defined”
“Attribute ”xyz“ has already been defined”
...

And i found that all these attributes are defined in declare-styleable of module abc and they are quite a lot . I dont know where they produce the duplicate since i can run normally from Eclipse, not Android Studio. Some suggests that to manually rename the attributes of those but I think it is time consuming.

Any better solution? Thank you!

This happens to me as well when I import project from Eclipse. Android Studio seems to binds library project even thou there was an error adding library modules.

I can usually fix this by firstly delete library modules, then opening Project's settings.gradle file and delete imports from there. After this, import of library modules works well.

And when I have issues with styleable file, I can usually fix this by setting SDK version to at least 20 (Android 5.0)
