Android Studio添加应用作为依赖时报错Error:Dependency MonthText:xlistview:unspecified on project app resolves to an APK archive which is not supported as a compilation dependency. File: 及其解决方案

Error:Dependency MonthText:xlistview:unspecified on project app resolves to an APK archive which is not supported as a compilation dependency. File: E:\Androidcode\androidstudioproject\MonthText\xlistview\build\outputs\apk\xlistview-release-unsigned.apk

解决方案：把依赖库的build.gradle文件中最上边的

　错误：　apply plugin: 'com.android.application'
  改为：  apply plugin: 'com.android.library'
还有：要删除defaultConfig中的applicationId "com.limxing.xlistview"
这个报错主要原因是因为依赖库之前是一个独立的应用，需要把它的设置为库，而不是应用

删除applicationId "com.limxing.xlistview"的原因是：applicationId 这是应用才有的id，库则没有，所以要删除
