我正试图在Alfresco的文件夹中上传一个文件，但我遇到了这个异常，我在过去两天试图解决这个问题，但没有任何机会。
我使用的是安卓版Alfresco Mobile SDK和AlfrescoCommunity 4.2。
以下是我如何上传文件，如果我做错了什么，请告诉我：
File fileToUpload = new File(selectedFilePath);
if((fileToUpload != null) && fileToUpload.isFile()) {
Log.d(MainActivity.DEBUGING, "File to upload's name: " + fileToUpload.getName());
String fileName = fileToUpload.getName();
String mimeType = getMimeType(selectedFilePath);
ContentFile contentFile = new ContentFileImpl(fileToUpload, fileName, mimeType);
try {
Log.w(MainActivity.DEBUGING, "create file: " + fileName + " of type: " + mimeType + " in: " + selectedFilePath);
session.getServiceRegistry().getDocumentFolderService().createDocument(currentFolder, fileName, properties, contentFile);
Toast.makeText(this, "file: " + fileName + " of type: " + mimeType + "in: " + selectedFilePath + " was created", Toast.LENGTH_LONG).show();
}
catch(org.alfresco.mobile.android.api.exceptions.AlfrescoServiceException e) {
Toast.makeText(this, "Upload failed ! ", Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
//
这是我在日志中得到的例外：

//我也尝试过在后台创建文件，但这一次，当loadInBackGround启动时，我的应用程序出现黑屏，过了一段时间，应用程序停止响应：（
DocumentCreateLoader contentCreator = new DocumentCreateLoader(this, session, currentFolder, fileName, properties, contentFile);
contentCreator.loadInBackground();
Aloah，
只是其他开发人员的一个快速提示：
如果你在崩溃后在日志中看到这一行
04-22 11:29:09.334:W/System.err（616）：由以下原因引起：android.os.NetworkOnMainThreadException
这意味着您需要在后台线程中运行代码，如AsyncTask、Loader、Thread。。。而不是应用程序的Main/UI线程。任何与网络相关的操作都必须在Android的主线程之外进行。
