How does setMicrophoneMute() work? http://stackoverflow.com/questions/6874881/how-does-setmicrophonemute-work to dig deeper into the source code. IAudioflinger is the interface to the AudioFlinger service and the call to virtual status_t setMicMute bool state Parcel data reply data.writeInterfaceToken IAudioFlinger getInterfaceDescriptor data.writeInt32 state.. is actually the Binder transaction to mute the microphone. The receiving side of the Binder call looks like status_t BnAudioFlinger onTransact uint32_t code const Parcel data Parcel reply uint32_t flags switch code ... case SET_MIC_MUTE.. ... and calls to the actual implementation of setMicMute in the AudioFlinger . Next step is to look at this function status_t AudioFlinger setMicMute bool state check calling permissions if settingsAllowed return PERMISSION_DENIED AutoMutex lock..
