For a little bit of background, "Android" unfortunately covers a vast range of different device models and OS versions, which often fail to follow any single standard when it comes to features like this. Nevertheless, if it's proven that MIDI in general works on some device, we should be able to do that as well. Covering everything is just more complicated than on other platforms.
That said, the latest batch of extensions to Android MIDI support should be out with version 2.19.1
, just being released. Whenever you receive it, please give it a new try and report the results, preferably with device and OS information. We have encountered some devices which play along very nicely, others which don't at all, and some which look fine on the surface but actually lose MIDI data every now and then, making recognition unreliable. Synth performance is yet another story.
Anyway, we're trying to get there, step by step, hardware permitting. As we're receiving wider test reports, we'll also get a better picture of the latest overall situation. Probably not completed yet but not forgotten either. Hopefully we managed to make at least someone happy this time.
