android 通过反射来使用隐藏的@hide方法

     try {
              Class clazz = CallSmsSafeService.class.getClassLoader().loadClass("android.os.ServiceManager");
         Method method = clazz.getDeclaredMethod("getService", String.class);
         IBinder ibinder = (IBinder) method.invoke(null, TELEPHONY_SERVICE);
         ITelephony.Stub.asInterface(ibinder).endCall();"color:#362e2b;">
     } catch (Exception e) {
         e.printStackTrace();
     }
