String types not allowed (at ‘slideEdge’ with value ‘end’)

I got following error when I try to build android TV sample application.

TVDemoApp\app\build\intermediates\exploded-aar\com.android.support\leanback-v17\22.1.1\res\transition-v22\lb_browse_entrance_transition.xml

How to fix

You need to update configuration of compile SDK version.

update build.gradle (Module: app) as follows.

1. specify compileSdkVersion as 22, not 21.

    compileSdkVersion 22

2. specify dependencies library version as

compile ‘com.android.support:recyclerview-v7:22.1.1‘
compile ‘com.android.support:leanback-v17:22.1.1‘
compile ‘com.android.support:appcompat-v7:22.1.1‘

and build again.
