With greenDAO 3.2.x we are improving Android studio compatibility. Actually, greenDAO 3.2.0 was already released a couple of weeks ago, without a notification post. The first 3.2 release aligned an internal dependency (JDT ) to work nicely with Android Studio 2.2. Also, it added Protocol Buffers support to annotations. Today we are releasing 3.2.1 for the greenDAO plugin. Note that the core greenDAO lib and the generator did not have to be updated and thus remain at V3.2.0. This plugin update further improves Android Studio and Jack compiler integration and fixes some bugs. Check the changelog for details.

Surprisingly, the core Java API just still offers Adler32 and CRC32, which were designed as checksums many years ago. Of course, there are many hash implementations available outside of the core Java API. However, Continue reading
