googleCredential fails on Android

See original GitHub issue

Thanks for stopping by to let us know something could be better!

GoogleCredential tries to use the Android/Apache version of Base64, not the one in the dependency. As this version is old, it doesn’t have the method decodeBase64.

This fails on the emulators and on a real Android device.

The code in client.util.base64 explicitly refers to the apache commons version of Base64, but this is not found at run-time.

Environment details

OS: Android 6 & 7
Java version: 1.8.0
google-api-java-client version: 27

Steps to reproduce

private static String getAccessToken(InputStream gc) throws IOException { GoogleCredential googleCredential = GoogleCredential .fromStream(gc) .createScoped(Arrays.asList(SCOPES));
