Android的文件上传不工作 [英] Android fileupload not working

问题描述

我与Android合作。我已经创建了一个Android应用程序这将文件上载到服务器。我用下面的code

<一个href=\"http://androidexample.com/Upload_File_To_Server_-_Android_Example/index.php?view=article_discription&aid=83&aaid=106\" rel=\"nofollow\">http://androidexample.com/Upload_File_To_Server_-_Android_Example/index.php?view=article_discription&aid=83&aaid=106

但我不能上传我的文件。这个应用程序显示上传开始，但没有文件被上传到我的服务器位置。

解决方案

Hi I am working with android. I have created an android app which uploads a file to the server. I have used the following code

http://androidexample.com/Upload_File_To_Server_-_Android_Example/index.php?view=article_discription&aid=83&aaid=106

But I am not able to upload my file. The App shows uploading started but no file gets uploaded to my server location.

解决方案

     private class SendHttpRequestTask extends AsyncTask<String, Void, String> {

        protected String doInBackground(String... params) {

           String url = params[0];

          String param1 = params[1];

          String param2 = params[2];

         Bitmap b = BitmapFactory.decodeResource(UploadActivity.this.getResources(), R.drawable.logo);



        ByteArrayOutputStream baos = new ByteArrayOutputStream();

        b.compress(CompressFormat.PNG, 0, baos);



        try {

             HttpClient client = new HttpClient(url);

             client.connectForMultipart();

             client.addFormPart("param1", param1);

             client.addFormPart("param2", param2);

             client.addFilePart("file", "logo.png", baos.toByteArray());

             client.finishMultipart();

              String data = client.getResponse();

         }

          catch(Throwable t) {

           t.printStackTrace();

       }



        return null;

     }



    @Override

      protected void onPostExecute(String data) {           

       item.setActionView(null);



       }



     }
