Android通过AIDL和反射调用系统拨打电话和挂断电话

首先在项目中添加ITelephony.aidl文件，我的如下：

注意：call（）方法的参数因版本不同，版本<=4.2.2的一个参数void call(String number);版本>=4.3的两个参数void call(String callingPackage,String number)

添加完ITelephony.aidl文件后，Rebuild Project一下（AS中的）。

接下来关键部分在启动窗体中，看代码：

   @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);
        Class<TelephonyManager> managerClass = TelephonyManager.class;//得到TelephonyManager的Class对象
        try {//得到挂断电话的方法
            Method getITelephony = managerClass.getDeclaredMethod("getITelephony", (Class[]) null);
            //打开权限
            getITelephony.setAccessible(true);
            //得到TelephonyManager对象
            TelephonyManager manager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
            //得到ITelephony对象,进行所需要的操作
            ITelephony iTelephony = (ITelephony) getITelephony.invoke(manager, (Object[]) null);
            try {
                //打电话
                iTelephony.call(getPackageName(),"xxxxxxxxxxx");
                Thread.sleep(5000);
                //挂电话
                iTelephony.endCall();
            } catch (RemoteException e) {
                e.printStackTrace();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

还有权限添加，over,好了！
