mt6735 如何在TP上Home、 back添加按键音

[DESCRIPTION]
进入情景模式->一般模式->勾选中触屏提示音，但是只有TP上menu键有按键音，home键&back键没有提示音，如何让
home&back键也有触屏提示音。
[SOLUTION]

phonewindowmanager.java
interceptKeyBeforeDispatching(){
...
//添加如下code
if(keyCode==KeyEvent.KEYCODE_BACK&&event.getAction()==KeyEvent.ACTION_DOWN){
Log.d(TAG,"interceptKeyBeforeDispatchingKEYCODE_BACK,keyeventactiondown");
AudioManageraudioManager=(AudioManager)mContext.getSystEMService(Context.AUDIO_SERVICE);
if(audioManager！=null){
audioManager.playSoundEffect(AudioManager.FX_KEY_CLICK);
}else{
Log.w(TAG,"Couldn'tgetaudiomanager");
}
}
if(keyCode==KeyEvent.KEYCODE_HOME&&event.getAction()==KeyEvent.ACTION_DOWN){
Log.d(TAG,"interceptKeyBeforeDispatchingKEYCODE_home,keyeventactiondown");
AudioManageraudioManager=(AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE);
if(audioManager！=null){
