最近我尝试使用Dropbox android应用程序集成
此应用程序获取用户当前位置并自动将其上传到dropbox
问题在于，我无法上传文件。 吐司节目＆＃34;似乎有错误＆＃34;
这是主要活动

// that Dropbox authentication completes properly.

try {
// Mandatory call to complete the auth
session.finishAuthentication();
// Store it locally in our app for later use
storeAuth(session);
setLoggedIn(true);
