I just implemented the Android Architecture Library in my Android project, everything works fine when i build the app gradle module, but i can't test it on a physical/emulator device this shows up on the message gradle build

Error:Could not resolve all files for configuration ':app:debugAnnotationProcessorClasspath'.

Could not resolve android.arch.lifecycle:compiler:1.0.0. Required by: project :app No cached version of android.arch.lifecycle:compiler:1.0.0 available for offline mode.
