Android 来电翻转静音实现源码

1.添加实现文件：

alps\packages\apps\InCallUI\src\com\android\incallui\SensorFunctionServiceIncall.java

2.添加来电响应位置：

alps\packages\apps\InCallUI\src\com\android\incallui\InCallActivity.java

    @Override    protected void onStart() {        Log.d(this, "onStart()...");        super.onStart();        // setting activity should be last thing in setup process        InCallPresenter.getInstance().setActivity(this);//cbk.flip.func.add      if (FeatureOption.FLIP_FUNC_SUPPORT) {        final boolean gFlipMuteEnabled = Settings.System.getInt(getContentResolver(),                Settings.System.FLIP_MUTE_INCOMMING_CALL, 0) != 0;      if (gFlipMuteEnabled) {final Intent i = new Intent(this, SensorFunctionServiceIncall.class);        i.setAction("com.android.services.telephony.common.ISensorFunctionServiceIncall");this.startService(i);//startService(getApplicationContext(), SensorFunctionServiceIncall.class);      }      }//cbk.flip.func.add    }
