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.
greenDAO 3.1.1 Bugfix Release
Today, we released a new version of greenDAO addressing some issues with @Entity annotations. If haven’t tried them yet, please give them a try. We think this is the most convenient way to work with greenDAO, or SQLite in general. For details on the 3.1.1 improvements, please check the changelog.
Performant Java hash functions – today’s Java hash problems and our solution
Today, core Java APIs lack high quality hash functions, and 3rd party implementations provide sub-optimal performance. As non-cryptographic hash function are important building blocks of software, this is a major bummer for developers.
Generally, the selection of available hash functions is plenty, and in the last decade, many new hash functions emerged with very good hashing properties. 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
greenDAO 3.1 released
4 weeks ago we released greenDAO 3.0 introducing @Entity annotations as an alternative to the generator project. We noticed some issues with this rather big update, and fixed most of those in greenDAO 3.1 (thanks to everyone who reported bugs!). The update also brings two new features:
Android ORM Performance 2016
With greenDAO 3 released, it’s time again to look at the Android ORM performance landscape and do some benchmarks. This time, we also tested newer ORMs for SQLite like DbFlow, requery, SQLDelight, and SquiDB. Also, we had an extensive look at benchmarks done by others. Let’s get started with our results:
Benchmarking on Android
I don’t believe in any statistics I didn’t fake myself (German saying)
Doing good performance benchmarks is hard and benchmarking on Android is no exception. Here is a checklist on how to do fair and robust benchmarks:
greenDAO 3 released
We are happy to announce greenDAO Version 3 today. Since its initial release 5 years ago, greenDAO has always been the fastest ORM for Android. It was also the first ORM to apply code generation for maximum performance. With greenDAO 3, we made code generation much more convenient: by adopting entity annotations you can drop the generator project. In its place comes the all new Gradle plugin, which automatically triggers code generation at build time. Like that, you can simply use greenDAO 3 annotations on your entities:

greenDAO 3 Beta released
We just released greenDAO 3 beta: it makes the generator project optional and moves to Java annotations. Before the final release however, we want to get your feedback. In particular, we experimented with alternative annotation processing that gives greenDAO more power while it avoids byte code manipulation.Our goal with greenDAO3 is to put the developer in control over entity classes while augmenting the entity code with a little bit of generated code.
