New warning when building android app with gradle

Question

Yesterday it was fine, today it shows this warning when I clean or build the project:

WARNING: Ignoring Android API artifact com.google.android:andr

Answer 1

I solved the problem by updating my version of gradle.

build.gradle (Project)

classpath 'com.android.tools.build:gradle:+'

Answer 2

Usually, java libraries depends on com.google.android:android if this library will be used in Android project.

Then you can exclude this module from dependencies of target Android project. Like this:

compile ('some.library.that.depends.on.android') {
    exclude group: 'com.google.android'
}
