Usb-Midi when Target API level is 31

[Jonathan10]

When switching to Target API level 31 it stops working.

It seems that there are no events at all.

With Api level 29 it works well.

any ideas how to fix it ?

Thanks.

Could you give me more details please ?

• Are you using the plugin with Unity or only with Java ?
• Are you receving the events for device attached / detached ?
• Are you receving the pending intent popup for using the usb port ?

Hi,

Setting FLAG_MUTABLE or rebuild the aar library resolved a compatibility issue with newest Android versions in my case, but there still issue that after NoteOff event also coming NoteOn in the next packet.

PendingIntent permissionIntent = PendingIntent.getBroadcast(_context, 0, new Intent(USB_PERMISSION_ACTION), FLAG_MUTABLE);

Tested on Unity and Java

About above issue with NoteOn/NoteOff, adding break fix this problem: switch (CIN) { case 0x8: _midiCallback.NoteOff(byte2); break; case 0x9: if(byte3 == 0x00) { _midiCallback.NoteOff(byte2); } else{ _midiCallback.NoteOn(byte2, byte3); } }

Hello,

I have fix the issue with your code in the last commit. But I didn't test it because I don't have my piano, can you test it for me ?

[Radomiej]

yes, this issue is already resolved, thanks! but I still need to update PendingIntent.FLAG_MUTABLE to make it working on API 33. and there also issue with gradle, which I've resolved by replace task clean with following code:

clean.doFirst { delete rootProject.buildDir }
