android - 下载apk文件。在 AVD 上工作正常，但在真手机上却不行

Question

您好，我正在尝试将 apk 文件从 Web 服务器下载到我的 android 应用程序 (/download) 目录。问题是：在 AVD 上工作正常，但在我的真手机 S2 上不要下载这个 apk 文件。请见鬼 :)

代码：`

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_update_apk);

    BroadcastReceiver receiver = new BroadcastReceiver() {
        @SuppressLint("NewApi")
        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) {

                //  openFile();

            }
        }
    };

    registerReceiver(receiver, new IntentFilter(
            DownloadManager.ACTION_DOWNLOAD_COMPLETE));


    /*
    //del old file
    File fileUpdate = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)+"/"+fileName);
    if(fileUpdate != null){
        fileUpdate.delete();
    }*/

    startDownload();
}

@SuppressLint("NewApi")
public void startDownload() {
    try{
        dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
        Request request = new Request(
                Uri.parse("http://10.10.10.10/andr_test/download_new_version/appUpdate.apk"));
        enqueue = dm.enqueue(request);
    } catch (Exception e) {
        Log.e("Can't download file", "Can't download file-" + e.getMessage());
    }
}`

host:10.10.10.10是你的真手机网络可以访问的真实主机吗？或者只是一个测试主机只能由您的桌面访问。
