android studio无法解析导入org.json.JSONObject [英] android studio cannot resolve import org.json.JSONObject
问题描述
我使用libgdx构建我的项目,并且遇到了使用 JSONObject 类的问题。当我添加 import org.json.JSONObject
时,它说它无法解析。如何将该库添加到我的项目中?
I used libgdx to build my project and I am having issues using the JSONObject class. When I add import org.json.JSONObject
, it says it cannot resolve. How do I add that library to my project?
以下是我未尝试成功的原因:
Here is what I have tried without success:
- 我下载了
json-simple-1.1.jar
并将其放入core / build / libs文件夹中。无法使用import.org.json.simple.JSONObject
。 - 当在Android Studio中浏览树作为Packages下拉列表时,我可以在
>Core - > Libraries - > org - > ; json
但我不能将它们添加到我的项目中。我得到一个不能折射,类在一个jar文件错误。
- I downloaded the
json-simple-1.1.jar
and put it in core/build/libs folder. Could not useimport.org.json.simple.JSONObject
either. - When browsing the tree in Android Studio as "Packages" dropdown, I can see the classes I want under
"Core -> Libraries -> org -> json"
but I cannot add them to my project. I get a "cannot refractor, class is in a jar file" error.
有没有我还没有尝试过解决这个问题问题?当我试图使用其他外部库时,我觉得我会再次遇到这个问题。
Is there something I have not tried yet to solve this issue? I feel I will run into this again as I try to use other external libraries.
谢谢。
推荐答案
如果您使用的是LibGdx,不带有Gradle设置,使得multy项目的构建更加简化。
If you are using LibGdx, it not comes with a Gradle setup making multy project builds streamlined.
请看这里: http://mvnrepository.com/artifact/org.json/json/ 。
您需要添加 compile'org.json:json:20160212'
到您的顶部 build.gradle
,例如:
You need to add compile 'org.json:json:20160212'
to your top build.gradle
, like:
dependencies {
compile 'org.json:json:20160212'
}
