Custom Fields For A Build Type In Gradle

I am trying to embed a few server addresses in my build.gradle file but I am unsure about how to do this. I know that in maven, you can write http://tes

Solution 1:

Gradle for Android offers buildConfigField, allowing you to add arbitrary data members to the code-generated BuildConfig class:

  buildTypes {
    debug {
      buildConfigField "String", "SERVER_URL", '"http://test.this-is-so-fake.com"'
    }

    release {
      buildConfigField "String", "SERVER_URL", '"http://prod.this-is-so-fake.com"'
    }

    mezzanine.initWith(buildTypes.release)

    mezzanine {
        buildConfigField "String", "SERVER_URL", '"http://stage.this-is-so-fake.com"'
    }
}

In your Java code, you can refer to BuildConfig.SERVER_URL, and it will be populated with the string based on the build type you choose at compile time.

Solution 2:

To just use a field independently from build types and product flavors, you could add it to your defaultConfig by:

defaultConfig {
    ...
    buildConfigField "String", "OS", '"android"'
}

Then the BuildConfig looks like this:

publicfinalclassBuildConfig{
    publicstaticfinalboolean DEBUG = Boolean.parseBoolean("true");
    publicstaticfinalString APPLICATION_ID = "com.example.app";
    publicstaticfinalString BUILD_TYPE = "debug";
    publicstaticfinalString FLAVOR = "";
    publicstaticfinalint VERSION_CODE = 1;
    publicstaticfinalString VERSION_NAME = "1.0";
    // Fields from default config.publicstaticfinalString OS = "android";

}
