* The recommended sequence is:
*
* Check for feature "android.hardware.audio.low_latency" using code such as this:
* import android.content.pm.PackageManager;
* ...
* PackageManager pm = getContext().getPackageManager();
* boolean claimsFeature = pm.hasSystemFeature(PackageManager.FEATURE_AUDIO_LOW_LATENCY);
* Check for API level 17 or higher, to confirm use of android.media.AudioManager.getProperty().
* Get the native or optimal output sample rate and buffer size for this device's primary output stream, using code such as this:
* import android.media.AudioManager;
* ...
* AudioManager am = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
* String sampleRate = am.getProperty(AudioManager.PROPERTY_OUTPUT_SAMPLE_RATE));
* String framesPerBuffer = am.getProperty(AudioManager.PROPERTY_OUTPUT_FRAMES_PER_BUFFER));
* Note that sampleRate and framesPerBuffer are Strings. First check for null and then convert to int using Integer.parseInt().
* Now use OpenSL ES to create an AudioPlayer with PCM buffer queue data locator.
*
