What is the equivalent of BuildConfig in Java module? - Android

Question

I'm using AndroidStudio and I have the following:

• Main Android project: app
• Java Library: communication

I want to set up my "communication" module's gradle file to achieve the following:

• As app module's gradle, I can setup variables for BuildConfig.java file, e.g.:

  buildTypes {
      release {
          ...
          buildConfigField "String", "SERVER_URL", '"my_url"'
      }
  
      debug {
          buildConfigField "String", "SERVER_URL", '"my_url"'
      }
  }
  

and then I can use them using BuildConfig.SERVER_URL

The question is: How do I achieve this using a Java Library module?

Answer 1

I think that you are looking for this Gradle plugin. It brings BuildConfig to pure Java module.

Answer 2

If by Java library you mean Android module then :

Set buildTypes variables inside the build.gradle file into library module like app module.

Get it by using the correct BuildConfig Class.

• my.package.app.BuildConfig.APP_VARIABLE
• my.package.library.BuildConfig.LIBRARY_VARIABLE

In other way, maybe you can take a look to gradle task and System Environment this answer can help you https://stackoverflow.com/a/25714617/4681367

There is no other way to get build configuration outside an Android module.

Just set/add an environment variable based on your android BuildConfig variables.
