in d:\users(user)\androidstudioprojects(project)\build\intermediates\exploded-aar\com.android.support\appcompat-v7\21.0.0-rc1\res\values-v21\values.xml

i have latest sdk downloaded i'm not sure problem is...

check appcompat-v7 version. has problem backward compatibility newest 1 (21.0.0-rc1) tries link ui components android l's material ones. (but of course fails because upgraded androidstudio version , not introduce newest sdk!) possible fix specify appcompat-v7's version in build.gradle this:

dependencies {     compile 'com.android.support:appcompat-v7:19.+' }
