[SOLUTION]
请按照如下方法进行修改：
php?mod=tag&id=6090" target="_blank" class="relatedlink">Frameworks\base\media\java\android\media\MediaFocusControl.java：
1、importpackages：
importcom.android.internal.telephony.ITelephony;
importandroid.os.ServiceManager;

2、增加获取当前PhoneCallState的方法getPhoneCallState()：
privateintgetPhoneCallState(){
intphoneCallState=TelephonyManager.CALL_STATE_IDLE;
TelephonyManagertelephonyManager=(TelephonyManager)mContext.getSystEMService(Context.TELEPHONY_SERVICE);
ITelephonytelephonyService=ITelephony.Stub.asInterface(ServiceManager.getService(Context.TELEPHONY_SERVI
CE));
if(telephonyService！=null){
Log.w(TAG,"getPhoneCallState:mTelephonyService！=null");
try{
phoneCallState=telephonyService.getPreciseCallState();
Log.w(TAG,"getPhoneCallState:telephonyService.getPreciseCallState()="+phoneCallState);
}catch(RemoteExceptionex){
if(telephonyManager！=null){
phoneCallState=telephonyManager.getCallState();
Log.w(TAG,"getPhoneCallState:telephonyManager.getCallState()="+phoneCallState);
}
Log.w(TAG,"CatchexceptionwhengetPreciseCallState:ex="
+ex.getMessage());
}
}else{
Log.w(TAG,"getPhoneCallState:telephonyService==null");
if(telephonyManager！=null){
phoneCallState=telephonyManager.getCallState();
Log.w(TAG,"getPhoneCallState:telephonyManager.getCallState()="+phoneCallState);
}
}
Log.w(TAG,"getPhoneCallState:phoneCallState="+phoneCallState);
returnphoneCallState;
}

3、修改
privatebooleancanReassignAudioFocus(){
//focusrequestsarerejectedduringaphonecallorwhenthephoneisringing
//thisisequivalenttoIN_VOICE_COMM_FOCUS_IDhavingthefocus
if(！mFocusStack.isEmpty()&&mFocusStack.peek().hasSameCLIent(IN_VOICE_COMM_FOCUS_ID)){
returnfalse;
}
returntrue;
}
为
privatebooleancanReassignAudioFocus(){
//focusrequestsarerejectedduringaphonecallorwhenthephoneisringing
//thisisequivalenttoIN_VOICE_COMM_FOCUS_IDhavingthefocus
if(！mFocusStack.isEmpty()&&mFocusStack.peek().hasSameClient(IN_VOICE_COMM_FOCUS_ID)&&(getPhoneCallState(
)！=TelephonyManager.CALL_STATE_IDLE)){
Log.w(TAG,"canReassignAudioFocus:returnfalse");
returnfalse;
}
Log.w(TAG,"canReassignAudioFocus:returntrue");
returntrue;
}

附：开启音效，把音量调到最大，背景播放音乐， 前景拨拔号按键音， 拨号音会破音

音乐播放器开启音效，然后把音量侧键调到最大，背景播放一个音乐， 然后去拨拔号按键音， 拨
号音会破音请修改替换\audioflinger\Effects.cpp中AudioFlinger::EffectModule::process()这
个函数中如下一行Code： tempValue = out + in;替换为： int64_t out_tmp = out;
int64_t in_tmp = in; tempValue = out_tmp + in_tmp;如果ok，请打patch：ALPS01852339
