How to Determine if Android Device's Audio Pipeline is Low-Latency

public static final String FEATURE_AUDIO_LOW_LATENCY was added in API level 9
Feature for getSystemAvailableFeatures() and hasSystemFeature(String).

The device's audio pipeline is low-latency, more suitable for audio applications sensitive to delays or lag in sound input or output.
Constant Value: "android.hardware.audio.low_latency"

1. Get a PackageManager Instance named myPackageManager.

2. Create a Boolean Variable named bolLLSupported. 

3. Set the Minimum and Target SDK version  to 9 or greater. 

4. In the onCreate method, add the below code. This will return the low-latency ability to a boolean named bolLLSupported. It will then display a toast displaying the low-latency ability of the device to the user.

bolLLSupported = myPackageManager.hasSystemFeature(PackageManager.FEATURE_AUDIO_LOW_LATENCY);

if (bolLLSupported) {

Toast.makeText(this, "Device has low-latency capability", Toast.LENGTH_LONG).show();

} else {

Toast.makeText(this, "No low-latency capability!", Toast.LENGTH_LONG).show();

}

5. Compile and run!
