Android support?

Title says it all :)

hello ! that would be nice - I would expect that it "just works" on android as Android uses ALSA behind the scene if I'm not mistaken but I do not knjow at all on iOS - is it not CoreMidi there too ?

[AlGrenadine]

Yes coremidi seems to work on iOS but alsa doesn't on Android afaik

[jcelerier]

damn I hope we don't have to call Java APIs to make it work

[AlGrenadine]

I fear you have to :(

[jcelerier]

just checked and apparently no ! android NDK comes with a C/C++ midi API:

In case it matters, Android Native MIDI API is available only in Android 10 or later.

argh :) communicating through JNI is an... exercice in patience to say the least (and I have very few experience with it).
I'd be ok with trying to do it with the more recent API, then if someone wants to contribute support for the java-based API it'll be 100 % welcome but I don't have the courage for it

[jcelerier]

50% done, I could make the library build for iOS, there were a couple minor things.

the code that seems required for android is .... yuck yuck yuck

Excellent :)

definitely not ahah, I'd rather like to avoid having some weird JNI calls and Java object discovery in the middle. Maybe it can be part of some example though - the end-user would be able to implement these calls however they see fit.

Anyway, now it's implemented in rtmidi it's still good news :)
