在Android棉花糖中挂断电话

问题描述

我正在尝试创建一个呼叫号码的应用程序，一旦接收者接听电话，它就会执行某些操作（说），然后它应自动挂断。

所以，我所做的是，在broadcastreceiver的onReceive方法中，一旦调用开始，我等待一段时间后延迟usign处理程序，然后调用cutTheCall（）方法挂断。

但是，呼叫在呼叫开始时就挂断了，而没有调用cutTheCall（）方法

CallReceiver [broadCastReceiver的子类]

package com.example.multicall;


import android.content.broadcastReceiver;
import android.content.Context;
import android.content.Intent;

import static android.content.Context.TELEPHONY_SERVICE;

public class CallReceiver extends broadcastReceiver {

    private Handler handler1 = new Handler();
    private static int wait = 0 ;

    private Runnable WaitToCutCall  = new Runnable() {
        @Override
        public void run() {
            if(wait < 1) {
                wait = wait + 1;
                handler1.postDelayed(this,20000);
            }
            else
            {
                wait =0 ;
            }
        }
    };


    @Override
    public void onReceive(Context context,Intent intent)
    {

        if(intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_OFFHOOK) )
        {
            showToast(context,"Call Started..");
            MainActivity.changeAllowNewCall(false);

            WaitToCutCall.run();

            cutTheCall( context );

        }

        TelephonyManager tm = (TelephonyManager)context.getSystemService(TELEPHONY_SERVICE);

        Method m1 = null;
        try {
            m1 = tm.getClass().getDeclaredMethod("getITelephony");
        } catch (NoSuchMethodException e) {
            e.printstacktrace();
        }
        m1.setAccessible(true);
        Object iTelephony = null;
        try {
            iTelephony = m1.invoke(tm);

            e.printstacktrace();
        } catch (InvocationTargetException e) {

        }

        Method m3 = null;

        } catch (NoSuchMethodException e) {

        } catch (InvocationTargetException e) {
            e.printstacktrace();
        }
    }
