导入模块中的任何内容都会导致Android Studio中出现“无法解析符号”错误

Question

I simply wanted to create a Jar archive (.jar file) out of my classes using Android Studio. To do so, I created a module using File > New > New Module > Java Library . Then I wrote two classes (LocationAndroidPlugin, MyLocationService) in the module:

But Android Studio complains that it cannot resolve the import statements in the classes:

I tried File > Invalidate Cache in vain.

My Android Studio version is: Android Studio 2.3.1 Build #AI-162.3871768, built on April 1, 2017 JRE: 1.8.0_112-release-b06 amd64 JVM: OpenJDK 64-Bit Server VM by JetBrains sro

Answer 1

You should not use Java Library option if you want to use serviceConnection, activity, or intent because it does not have Android classes. Instead, you must create the new module as an Android Library from File > New > New Module > Android Library .
