以下代码是将视频上传到服务器的后台任务示例。没有什么特定于 Android Studio - 无论您的 IDE 是 Eclipse 还是 Studio（或其他任何东西......），它都应该可以工作。

    /* This Class is an AsynchTask to upload a video to a server on a background thread
     * 
     */

    private VideoUploadTaskListener thisTaskListener;
    private String serverURL;
    private String videoPath;

        //Constructor
        Log.d("VideoUploadTask","constructor");

        //Set the listener
        thisTaskListener = ourListener;
    }

    @Override
    protected Integer doInBackground(String... params) {
        //Upload the video in the background
        Log.d("VideoUploadTask","doInBackground");

        //Get the Server URL and the local video path from the parameters
        if (params.length == 2) {

        httpclient.getConnectionManager( ).shutdown( );
