can someone help me fix this thanks.

Answer 1

This is because 21.0.1 for support libraries does not exist .

You can use one of the following in build.gradle :

 dependencies{ //it requires compileSdkVersion 23 compile 'com.android.support:appcompat-v7:23.2.0' compile 'com.android.support:appcompat-v7:23.1.1' compile 'com.android.support:appcompat-v7:23.1.0' compile 'com.android.support:appcompat-v7:23.0.1' compile 'com.android.support:appcompat-v7:23.0.0' //it requires compileSdkVersion 22 compile 'com.android.support:appcompat-v7:22.2.1' compile 'com.android.support:appcompat-v7:22.2.0' compile 'com.android.support:appcompat-v7:22.1.1' compile 'com.android.support:appcompat-v7:22.1.0' compile 'com.android.support:appcompat-v7:22.0.0' //it requires compileSdkVersion 21 compile 'com.android.support:appcompat-v7:21.0.3' compile 'com.android.support:appcompat-v7:21.0.2' compile 'com.android.support:appcompat-v7:21.0.0' } 

The same goes for com.android.support:recyclerview-v7

Answer 2

I ran into a similar problem and installed the SDK build tools for Android -v23.0.1 and sent the Android setup guide https://facebook.imtqy.com/react-native/docs/android-setup.html#content

but could not find the "Android support repository", for the latest version of the SDK manager - the parameter is changed to "Local maven repository for support libraries".

Answer 3

I think the line buildToolsVersion "23.0.0 rc2" is causing the problem.

change it to buildToolsVersion "21.0.1"

or try

 compileSdkVersion 21 buildToolsVersion "22.0.1" 

and

 compile 'com.android.support:appcompat-v7:22.2.0' 

and yes, what Sharj said is correct too, maybe you are missing build tools
