java - 在android项目中添加外部依赖jar

Question

我正在尝试将外部 jar 添加到我的 android 项目中。这些外部 jar 相互依赖，其中一些依赖于另一个 jar，因此当引用位于另一个 jar 文件中的类时，android studio 会为该类抛出 java.lang.NoClassDefFoundError。

在 android 项目中使用这些类型的 jar 的正确解决方案是什么？？

  compile files('libs/gt-shapefile-2.7.5.jar')
compile files('libs/gt-metadata-2.7.5.jar')
compile files('libs/gt-data-2.7.5.jar')
compile files('libs/gt-main-2.7.5.jar')
compile files('libs/gt-api-2.7.5.jar')
compile files('libs/gt-referencing-2.7.5.jar')
compile files('libs/vecmath-1.3.2.jar')
compile files('libs/commons-pool-1.5.4.jar')
compile files('libs/gt-opengis-2.7.5.jar')
compile files('libs/jsr-275-1.0-beta-2.jar')
compile files('libs/jts-1.11.jar')
compile files('libs/jdom-1.0.jar')
compile files('libs/jai_core-1.1.3.jar')
compile files('libs/hsqldb-1.8.0.7.jar')
compile files('libs/gt-epsg-hsql-2.7.5.jar')

可以引用this回答以获得添加 jar 库的正确方法。

1. First switch your folder structure from Android to Project. enter image description here

2. Now search for the libs folder inside app - build folder.

3. Once you have pasted the .jar file inside libs folder. Right click on the jar file and at end click on Add as library. This will take care of adding compile files('libs/library_name.jar') in build.gradle [You don't have to manually enter this in your build file]. enter image description here

   

   Now you can start using the library in your project.
