贴一段代码，关于自动接听的，请老司机帮帮忙

public synchronized void answerRingingCall(Context context) {
    try {
        Log.e("try to answer", "below 2.3");
        //ITelephony itelephony = getITelephony(mTelephonyManager);
        Method method = Class.forName("android.os.ServiceManager").getMethod("getService", String.class);
        IBinder binder = (IBinder) method.invoke(null, new Object[]{TELEPHONY_SERVICE});
        ITelephony itelephony = ITelephony.Stub.asInterface(binder);
        //itelephony.silenceRinger();
        itelephony.answerRingingCall();
    } catch (Exception e1) {
        Log.e("try to answer","2.3~4.1",e1);
        try {
            Intent localIntent1 = new Intent(Intent.ACTION_HEADSET_PLUG);
            localIntent1.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
            localIntent1.putExtra("state", 1);
            localIntent1.putExtra("microphone", 1);
            localIntent1.putExtra("name", "Headset");
            context.sendOrderedBroadcast(localIntent1,"android.permission.CALL_PRIVILEGED");

            Intent localIntent2 = new Intent(Intent.ACTION_MEDIA_BUTTON);
            KeyEvent localKeyEvent1 = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_HEADSETHOOK);

最近在做一个关于通话的app，网上收集了些资料，但都比较老，整理出了这段代码，跑在模拟器上，用终端模拟电话呼入，模拟器只有5.0（API 21）的版本
结果代码跑到了"for 4.1 and above way1"这段里，也没有报错，但却无法接起电话。不知道是模拟器的原因，还是代码的问题？手边没有android的手机所以只能在模拟器折腾，请老司机帮帮忙～
