Problem solved by the feature

The README only specifies that Java 7 is the minimum version for the latest Gson versions. However, for Android developers this information is not that helpful because Java 7 API was added in multiple different Android API levels. For example java.lang.ReflectiveOperationException added in Java 7 was only added for Android API level 19 (Android 4.4), see also #2310 (comment).

Feature description

• The README should explicitly state which Android API level is the minimum
• The build setup should verify that no newer Android APIs are used (respectively that desugaring is supported).
  This can be verified using Animal Sniffer, see:
  • Experiment with checking against *Android* Animal Sniffer signatures guava#4005
  • Android Scents for Maven
    (to be verified that these artifacts are safe; but appears they are also used by other projects, e.g. OkHttp (code))
    • https://sourceforge.net/projects/androidscents/
    • https://search.maven.org/search?q=g:net.sf.androidscents.signature
  • Animal Sniffer signatures, considering desugaring: https://github.com/open-toast/gummy-bears
    In that case would have to explicitly mention desugaring (using the latest Android build tools?) in the README
