-// Each platform must implement an AudioPolicyManager class derived from AudioPolicyManagerBase
-// and override methods for which the platform specific behavior differs from the implementation
-// in AudioPolicyManagerBase. Even if no specific behavior is required, the AudioPolicyManager
-// class must be implemented as well as the class factory function createAudioPolicyManager()
-// and provided in a shared library libaudiopolicy.so.
