客户报告了一个奇怪的错误.在AsyncTask中执行正常的AndroidHttpClient.execute()时,应用程序崩溃并获得以下堆栈跟踪

为什么调用checkMMSSendPermission和isSmsRequest？我们根本没有使用彩信和短信,而且应用程序没有这些权限,我想这就是它崩溃的原因.这适用于所有其他99.9%的用户.

代码看起来像这样

AndroidHttpClient client = AndroidHttpClient.newInstance(null);
        InputStream inputStream = null;
        try
        {
            HttpPost request = new HttpPost(urlString);
            prepareURLRequest(request);
            HttpResponse response = client.execute(request);
            mResultStatus = response.getStatusLine().getStatusCode();
            inputStream = response.getEntity().getContent();
...

欢迎任何帮助

更新

这似乎只影响索尼Xperia Z,Z1和ZR手机.显然,在收到Android 4.3更新后问题就开始出现了.没有人使用这些手机可以使用我们的应用程序,但除此之外,它的工作原理.
