Android文件上传到某些设备上的php脚本问题

Question

In my android app I upload some files to a php script. The code works fine on my tablet, but on some other devices, the upload failes. The size of the files are the some on the devices.

My upload code:

 HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("myurl"
                + "/Mysql_Filesave.php");
        JSONObject json = new JSONObject();

        json.put("Type", type);
        json.put("FileName", files[i].getName());
        json.put("LocalPath", path);
        JSONArray postjson = new JSONArray();
        postjson.put(json);


        // Post the data:
        httppost.setHeader("json", json.toString());
        httppost.getParams().setParameter("jsonpost", postjson);

        MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
        FileBody fileBody = new FileBody(files[i]);
        reqEntity.addPart("file", fileBody);
        httppost.setEntity(reqEntity);      

        HttpResponse response = httpclient.execute(httppost);

My PHP Code for checking if there is a file:

if (!isset($_FILES['file']['tmp_name'])) {      
    die("No file available");
}

So some devices die on this check. The files are about 10 megabytes big. On the php server I allow files up to 50M.

What can the problem be? I don't have a clue, because on some devices it works, on other not.

Best regards, Peter

Found the problem myself: Fixed some php.ini parameters (max memory, max_post_size), now the upload is working
