Change the compileSdkVersion
in your build.gradle
file to refer directly to the GDK add-on:
android {
compileSdkVersion "Google Inc.:Glass Development Kit Preview:19"
buildToolsVersion "19.0.2"
// other stuff...
}
(The buildToolsVersion
can be newer than 19.0.2 if you have a higher version of the SDK installed, as long as it's at least 19.0.2.)
