Installing Repository For Com.android.support.recyclerview-v7 For Android Studio Error

I'm a beginner in android studio and I try to use a recyclerView. When I try to add compile 'com.android.support.recyclerview-v7:21.0.+' to my gradle file, I get the error: failed

Solution 1:

First of all, run the SDK Manager and check if your support libraries repository is updated.

Then open your build.gradle (not the top level file) and add:

dependencies{

    //....
    compile 'com.android.support:recyclerview-v7:23.0.0'
}

Pay attention. You report in your question a typo in your library (compile 'com.android.support.recyclerview-v7:21.0.+')

Using the v23 you have to compile with API23.

Of course you can use a "old" version using:

compile'com.android.support:recyclerview-v7:22.2.1'compile'com.android.support:recyclerview-v7:21.1.3'
