Android OpenSLES: use common DetectDevices function

and so, this should also immediate for OpenSLES, @v3rm0n ?

[v3rm0n]

Not sure if it would break anything but currently it wouldn't do much because openSLES driver does not have AllowsArbitraryDeviceNames set to true.

[1bsyl]

Just adding it

    impl->OnlyHasDefaultOutputDevice = SDL_FALSE;
    impl->OnlyHasDefaultCaptureDevice = SDL_FALSE;
    impl->AllowsArbitraryDeviceNames = SDL_TRUE;

[v3rm0n]

Looks better, but I haven't found a way to pass the device information to openSLES so it would actually try to use the chosen device...

Also a separate issue maybe: event handlers (adding/removing audio devices) can run before audio system is inited and since the driver is null they will error out.

[1bsyl]

devname is sent to opensles.

for capture, it seems there is openslES_CreatePCMRecorder that should be modified to fill:

255     loc_dev.locatorType = SL_DATALOCATOR_IODEVICE;
256     loc_dev.deviceType = SL_IODEVICE_AUDIOINPUT;
257     loc_dev.deviceID = SL_DEFAULTDEVICEID_AUDIOINPUT;
258     loc_dev.device = NULL;

but for output, not so obvious to select the device

This hasn't been updated in a while and we're cleaning house for SDL 3.0. Please feel free to reopen this if you'd like to clean it up and get it in!
