The reason for this step is quite simple: this project is not sponsored neither by Google nor by Oracle and donations do not work. Also the attempt to create a paid version failed to cover the costs. In addition to this my current job is now very unrelated to NetBeans/IDEs/Android and I meant to freeze all my activity related to NBAndroid. The only way how to change my mind is to convince me through these bounties that this is worth the effort.
Also I am ready to pass project ownership to someone new who would be able to keep it alive.
