AudioDeviceModule (Video Android 7.5.1)

All Known Implementing Classes:

JavaAudioDeviceModule, LegacyAudioDeviceModule
```
public interface AudioDeviceModule
```
This interface is a thin wrapper on top of a native C++ webrtc::AudioDeviceModule (ADM). The reason for basing it on a native ADM instead of a pure Java interface is that we have two native Android implementations (OpenSLES and AAudio) that does not make sense to wrap through JNI.
Note: This class is still under development and may change without notice.

- Method Detail
  - getNativeAudioDeviceModulePointer
```
long getNativeAudioDeviceModulePointer()
```
    Returns a C++ pointer to a webrtc::AudioDeviceModule. Caller does _not_ take ownership and lifetime is handled through the release() call.
  - release
```
void release()
```
    Release resources for this AudioDeviceModule, including native resources. The object should not be used after this call.
  - setSpeakerMute
```
void setSpeakerMute(boolean mute)
```
    Control muting/unmuting the speaker.
  - setMicrophoneMute
```
void setMicrophoneMute(boolean mute)
```
    Control muting/unmuting the microphone.
