问题描述

您好，我使用MIT应用发明2使该在一个旧（备用）上运行的应用程序的Andr​​oid手机，以显示当前正在播放的电影folder.jpg（后来我也想这样做与音乐）。

我无法过滤使用的路径，例如这是JSON的结果是：

<$p$p><$c$c>{\"id\":\"VideoGetItem\",\"jsonrpc\":\"2.0\",\"result\":{\"item\":{\"id\":1,\"label\":\"2012\",\"thumbnail\":\"image://F%3a%5cMovies%5c2012%5cfolder.jpg/\",\"type\":\"movie\"}}}

在成对的查询阻止使用 JSON德code 块在一起。正如你所看到的，它有助于用做...

Hello i am using MIT App Inventor 2 to make an app that runs on an old (spare) android phone to display the folder.jpg of currently playing movie (later on I also want to do that with music).

I can't filter the path to use, for example this is the result of the json:

{"id":"VideoGetItem","jsonrpc":"2.0","result":{"item":{"id":1,"label":"2012","thumbnail":"image://F%3a%5cMovies%5c2012%5cfolder.jpg/","type":"movie"}}}

I want to keep: image://F%3a%5cMovies%5c2012%5cfolder.jpg which is the dvd cover (and maybe the label: 2012 which is the title of the movie).

I tried various options like making a list but then I still get text with lot of params between '()'
Can someone help me with this?
Thanks
