GST 3.10 upgrade guide

Review when migrating to Genero Studio 3.10.

ANDROID_SDK_ROOT replaces ANDROID_HOME

The ANDROID_HOME environment variable is deprecated. To define the Android SDK installation directory, use ANDROID_SDK_ROOT instead.

Note: The gmabuildtool will first use ANDROID_SDK_ROOT, then ANDROID_HOME as fallback.

If you previously used ANDROID_HOME, you can continue to use it but consider changing your environment settings to follow Android SDK specifications.
