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
		
    }
