android - 如何在 kotlin 中获取当前构建变体

Question

我的 Android 项目中有几个构建变体。

如何检查 Kotlin 代码中正在编译的变体？我想提出这样的条件:如果它是本地变体，那么如果它是远程变体，则执行此操作...

例如这样的事情:

// kotlin code:
if (build.variant=="local") {
...
}
else
{
...
}

At build time, Gradle generates the BuildConfig class so your app code can inspect information about the current build.

查看该类提供的选项:taken from

public final class BuildConfig {
  public static final boolean DEBUG = Boolean.parseBoolean("true");
  public static final String APPLCATION_ID = "com.example.app";
  public static final String BUILD_TYPE = "debug";
  public static final String FLAVOR = "";
  public static final int VERSION_CODE = 1;
  public static final String VERSION_NAME = "";
}

您还可以根据需要定义自定义变量:

android {
  ...
  buildTypes {
    release {
      // These values are defined only for the release build, which
      // is typically used for full builds and continuous builds.
      buildConfigField("String", "BUILD_TIME", "\"${minutesSinceEpoch}\"")
      resValue("string", "build_time", "${minutesSinceEpoch}")
      ...
    }
    debug {
      // Use static values for incremental builds to ensure that
      // resource files and BuildConfig aren't rebuilt with each run.
      // If they were dynamic, they would prevent certain benefits of
      // Instant Run as well as Gradle UP-TO-DATE checks.
      buildConfigField("String", "BUILD_TIME", "\"0\"")
      resValue("string", "build_time", "0")
    }
  }
}

并使用它:

Log.i(TAG, BuildConfig.BUILD_TIME)
Log.i(TAG, getString(R.string.build_time))
