通话录音：

从界面开始找代码，最后转了几个函数名，并转到多媒体录音模块
start_ record
voiceRecordClicked --- CallButtonFragment.java
|-------

com/android/incallui/CallButtonPresenter.java
public void voiceRecordClicked() {
TelecomAdapter.getInstance().startVoiceRecording();
}

|----
packages/apps/Dialer/InCallUI/src/com/android/incallui/TelecomAdapter.java
void startVoiceRecording() {
if (mInCallService != null) {
mInCallService.startVoiceRecording();
} else {

Log.e(this, "error startVoiceRecording, mInCallService is null");
}
}

|---- packages/services/Telecomm/src/com/android/server/telecom/InCallAdapter.java
public void startVoiceRecording()
PhoneRecorderHandler.getInstance().startVoiceRecord(activeCall,
|----import com.mediatek.telecom.recording.PhoneRecorderHandler
|------./Telecomm/src/com/mediatek/telecom/recording/PhoneRecorderHandler.java

public void startVoiceRecord(Call activeCall, final int customValue) {
mPhoneRecorder.startRecord();
private IPhoneRecorder mPhoneRecorder;

mRecordHandler = new RecordHandler(mWorkerThread.getLooper());

|----
./Telecomm/src/com/mediatek/telecom/recording/PhoneRecorder.java
public void startRecord() {

startRecording(MediaRecorder.O
|---./Telecomm/src/com/mediatek/telecom/recording/Recorder.java

private MediaRecorder mRecorder; 转化为多媒体里的录音模块

startRecording(int outputfileformat

mRecorder = new MediaRecorder();

mRecorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL);
mRecorder.start();

|-----AudioFlinger::RecordThread::RecordTrack::RecordTrack(

|------AudioFlinger::RecordThread::RecordTrack::start

|-----frameworks/av/media/libmedia/AudioRecord.cpp

|---- status_t AudioRecord::start(AudioSystem::sync_event_t

|----sp<IAudioRecord> AudioFlinger::openRecord(

|-----audio_module_handle_t AudioFlinger::loadHwModule_l(const char *name)
