Struct oboe_sys::oboe_DefaultStreamValues

#[repr(C)]pub struct oboe_DefaultStreamValues {
    pub _address: u8,
}

On API 16 to 26 OpenSL ES will be used. When using OpenSL ES the optimal values for sampleRate and framesPerBurst are not known by the native code. On API 17+ these values should be obtained from the AudioManager using this code:

// Note that this technique only works for built-in speakers and headphones.
AudioManager myAudioMgr = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
String sampleRateStr = myAudioMgr.getProperty(AudioManager.PROPERTY_OUTPUT_SAMPLE_RATE);
int defaultSampleRate = Integer.parseInt(sampleRateStr);
String framesPerBurstStr = myAudioMgr.getProperty(AudioManager.PROPERTY_OUTPUT_FRAMES_PER_BUFFER);
int defaultFramesPerBurst = Integer.parseInt(framesPerBurstStr);

It can then be passed down to Oboe through JNI.

AAudio will get the optimal framesPerBurst from the HAL and will ignore this value.
