如何使用foursquare从Android上传图片？

我知道如何处理与Foursquare的API https://developer.foursquare.com/docs/photos/add 如何使用foursquare从Android上传图片？

这里是我的代码：

protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if (requestCode == CAMERA_PIC_REQUEST) { 
     if (resultCode == RESULT_OK) { 
      Uri imageUri = data.getData(); 
      List<NameValuePair> params = new ArrayList<NameValuePair>(4); 
      Intent intent = getIntent(); 
      String message = intent.getStringExtra(SignIn.EXTRA_MESSAGE); 
      params.add(new BasicNameValuePair("venueId", message)); 
      params.add(new BasicNameValuePair("image", imageUri.getPath())); 
      Log.d("myresponse", imageUri.getPath()); 
      params.add(new BasicNameValuePair("oauth_token", 
        [myoauthtoken])); 
      params.add(new BasicNameValuePair("v", "20121210")); 
      post("https://api.foursquare.com/v2/photos/add", params); 
     } 
    } 
}

，但我得到这个堆栈跟踪异常：

mime.content表示文本可能不为空，因此请尝试将图像的MIME类型添加到Bundle中。 – DeeV

@DeeV我该怎么做？ – Aboelseoud

无论如何，错误已经改变。 – Aboelseoud

您正试图在您的UI线程上发出HTTP请求。 NetworkOnMainThreadException是个例外，这意味着您应该在后台线程中完成您的工作。

为了保证您的上传，我建议您使用类似IntentService的内容来做您的HTTP发布。除了documentation之外，您还可以查看我的example app，其中突出显示了在UI线程之外完成工作的不同方法。
