Android example not working

[systemcode]

I have tried the example v 0.3.7 on iOS and MACOS and it works fine.

It fails to show any devices on Android. The app screen is empty with no devices listed. Using SDK 28 and 29 on android 10 on a real device and emulator.

Are you testing a clean app install or did you update an older version of the example app?

Targeting SDK 29 and higher requires fine location permissions, which is a change from previously only needing coarse location.

The error you show mentions showRationaleForPermission, so my guess is it’s related to the change in location permissions from earlier.

Clean clone into a new folder.

I’ve tried both SDK 28 and 29.

TBH Although I’ve released iOS apps with your plugin, I’m new to Android. My main apps seem to work fine on Android except for this.

What SDK would you recommend?

Just to confirm. Is it also a fresh install on the device? Meaning, the old (if any) example app has been deleted before the new one gets installed.

I haven’t seen this issue myself, but will look into it.

Fresh clone from GitHub into fresh folder.

Tried SDK 28 and 29

iOS emulator and real device and MacOS ok.

Run without any changes using IntelliJ as well as flutter run.

Fails on both: Pixel device emulator. No app previously installed. New Android tablet. V10

I deleted and reinstalled allowing location perms. Still no list of devices displayed.

Ok - The reason there is no list of devices is that Network Session is not displayed as it is with ios and macos. I connected a cable to a USB Midi device and all is good. I tend to use Network Session with iOS emulators and macos routed through to a MIDI port when in development on MAC.

slightly related issue - on emulator, there is no BT so an exception occurs which is is handled internally but I've got a tidyup fix which I'll PR.

So is Network Session a deliberate omission?

To my knowledge Network Sessions is an Apple term for MIDI over TCP or RTP-MIDI and only Apple implements it as standard.
