很抱歉长代码，但我认为这是描述问题的最佳方式。所以最后任何人都可以帮我解决这个问题。感谢
3 个答案:
答案 0 :(得分：4)
看起来你有依赖问题。您的错误中有几行代表它无法找到类：
Could not find class 'org.json.simple.JSONArray', referenced from method com.dropbox.client2.DropboxAPI.revisions
Could not find class 'org.json.simple.JSONArray', referenced from method com.dropbox.client2.DropboxAPI.search
Could not find class 'org.json.simple.parser.JSONParser', referenced from method com.dropbox.client2.RESTUtility.parseAsJSON
您是否将包含这些类的JAR作为项目的一部分？如果是这样，它们是否在你的构建路径上？这可以解释你所看到的。
答案 1 :(得分：2)
可能你只是包含了＆＃34; dropbox-android-sdk-1.6.3.jar＆＃34;在你的libs目录
包含显示此图表的所有.jar文件
不要包含commons-logging-1.1.1.jar，因为你会遇到问题。
希望得到这个帮助。
答案 2 :(得分：0)
最终的解决方案应该是： 1.打开两个jar文件; dropbox-sync-sdk-android.jar和dropbox-android-sdk-1.6.1.jar 2.删除前sdk中的client2文件夹，并将其替换为后者的client2 3.然后下载json_simple-1.1.jar的副本。 4.将json_simple-1.1.jar和dropbox-sync-sdk-android.jar复制到libs文件夹中，并将这两个包含在项目属性中;这有助于避免将来出现错误
注意：你不需要在任何地方都包含dropbox-android-sdk-1.6.1.jar。
