如何将com.android.internal.telephony.ITelephony导入Android应用程序

Question

我想挂断来电我检测到它然后我想把它挂起来.

问题是这个:com.android.internal.telephony.ITelephony没有解决.

我尝试将包添加com.android.internal.telephony到我的应用程序并创建界面:

package com.android.internal.telephony;

public interface ITelephony {      

    boolean endCall();     

    void answerRingingCall();      

    void silenceRinger(); 

}

但电话没有结束.

在这里,我检测到呼叫,显示吐司(显示)然后尝试挂断,但正如我先说的那样,com.android.internal.telephony.ITelephony在我创建该包之前没有:

private class CallStateListener extends PhoneStateListener {
        @Override
        public void onCallStateChanged(int state, String incomingNumber) {
            switch (state) {
            case TelephonyManager.CALL_STATE_RINGING:
                // called when someone is ringing to this phone
                Toast.makeText(ctx, "Incoming: " + incomingNumber, Toast.LENGTH_LONG).show();
                 try{
                        TelephonyManager tm = (TelephonyManager) ctx.getSystemService(Context.TELEPHONY_SERVICE);
                        Class c = Class.forName(tm.getClass().getName());
                        Method m = c.getDeclaredMethod("getITelephony");
                        com.android.internal.telephony.ITelephony telephonyService = (com.android.internal.telephony.ITelephony) m.invoke(tm);  

                        telephonyService = (com.android.internal.telephony.ITelephony) m.invoke(tm);
                        telephonyService.silenceRinger();
                        telephonyService.endCall();
                    }catch (Exception e) {
                        e.printStackTrace();

                    }
                break;
            }
        }
    }

我的清单和权限:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.a"
    android:versionCode="1"

该ITelephony接口是内部的,所以你不能得到一个标准的参考吧.你可以一直使用反射,即

TelephonyManager tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);

Method m1 = tm.getClass().getDeclaredMethod("getITelephony");
m1.setAccessible(true);
Object iTelephony = m1.invoke(tm);

Method m2 = iTelephony.getClass().getDeclaredMethod("silenceRinger"); 
Method m3 = iTelephony.getClass().getDeclaredMethod("endCall"); 

m2.invoke(iTelephony);
m3.invoke(iTelephony);

但无论哪种方式,这些方法都需要MODIFY_PHONE_STATE权限,只能授予系统应用程序.所以我担心它无论如何都行不通.
