部分客户要求如下：
1.FM播放时拔出耳机后,FM APP出现“拔出耳机，Fm停止"的提示框，然后自动close ;
2.FM播放时进入飞行模式后,FM APP出现“进入飞行模式，Fm停止"的提示框，然后自动close.
 
修改FMRadioService.java
1.添加如下import,以便能显示toast

////AAAAA add start

import android.widget.Toast;

////AAAAA add end
public class FMRadioService extends Service implements FMRecorder.OnRecorderStateChangedListener {
 
2.在下面函数onBind()前添加 

//AAAAA add start

 public static final int MSG_EXIT_FM = 1234;

 private Handler sHandler11 = new Handler() {

   @Override

   public void handleMessage(Message msg) {

    LogUtils.d(TAG, "sHandler11 =  " + msg.what);

    switch (msg.what) {

     case MSG_EXIT_FM:

      android.os.Process.killProcess(android.os.Process.myPid());

      break;

    }

   }

 };
 private Toast mToast = null;
 private void showToast(CharSequence text) {

 if (null == mToast) {

     mToast = Toast.makeText(mContext, text, Toast.LENGTH_SHORT);

     }

        mToast.setText(text);

        mToast.show();

        LogUtils.v(TAG, "FMRadioActivity.showToast: toast = " + text);

    };

//AAAAA add end

@Override

    public IBinder onBind(Intent intent) {

        return mBinder;

    }
 
3.修改onReceive 方法,这样子就可以显示toast以及关闭Fm app了

在  switchAntennaAsync(mValueHeadSetPlug);

之后添加：

 if(mValueHeadSetPlug == 1 && mIsPowerUp )

{

   showToast(getString(R.string.toast_plugin_headphone_before_FM));

   sHandler11.sendMessageDelayed(sHandler11.obtainMessage(MSG_EXIT_FM, FMRadioService.this),(long)
1000);
mFmServiceHandler.removeCallbacksAndMessages(null);

stopFMFocusLoss(AudioManager.AUDIOFOCUS_LOSS);

}

 else

 sHandler11.removeMessages(MSG_EXIT_FM);
 
4.修改onReceive 方法,这样子就可以在进入飞行模式时显示toast以及在关闭Fm app了

        public void onReceive(Context context, Intent intent)
在

else {

                LogUtils.w(TAG, "Error: undefined action.");

  }

之前添加：

else if(Intent.ACTION_AIRPLANE_MODE_CHANGED.equals(action)){

       boolean isAirPlaneMode = intent.getBooleanExtra("state",false);

       if(isAirPlaneMode){

           LogUtils.d(TAG, ">>>ACTION_AIRPLANE_MODE_CHANGED");

           if (mIsPowerUp) {

                  showToast(getString(R.string.toast_fm_enter_airplane_mode)); 

                  sHandler11.sendMessageDelayed(sHandler.obtainMessage(MSG_EXIT_FM, FMRadioService.this),(long)1000); 

                  mFmServiceHandler.removeCallbacksAndMessages(null); 

                  stopFMFocusLoss(AudioManager.AUDIOFOCUS_LOSS);
                   }

             }  

}
 
4.修改    public void onCreate() 

在        filter.addAction(Intent.ACTION_SCREEN_OFF);

之后添加        filter.addAction(Intent.ACTION_AIRPLANE_MODE_CHANGED);
 
5.在alps\mediatek\packages\apps\FMRadio\res\values\strings.xml中添加

<string name="toast_plugin_headphone_before_FM">The FM will close because you have been plug out
the headphone</string>
<string name="toast_fm_enter_airplane_mode">The FM will close because you have been entered the
airplane mode</string>
