java.lang.NoClassDefFoundError: java.nio.charset.StandardCharsets in Android API < 19

Hi,

we have problems with the latest version of your library in devices running Android 4.3 (API 18) or lower. StandardCharsets was added in Android API 19 so any call to methods using that (for example, StringUtils.getBytesUtf8 or StringUtils.newStringUtf8) causes a crash in our app.

Environment details

• OS: Android API < 19
• google-http-java-client version: 1.28

FWIW, it's a bug as it was working fine in release 1.33.0.

Now in 1.34.x release we should at least get a warning that this library requires API 19 or above.
