When I click to run a project I just created in Android Studio 0.2.10 and select my Android (connected by USB with debug by USB on) I get this error:
Waiting
I tried most above offered solutions (the simple ones, not those offering chmod and altering internal libraries) and none of them work
Eventually what worked for me was: "Clean Project" -> "Rebuild Project" -> changed the app versionName in the build.gradle app module -> Sync Gradle -> Run the app on the device
