buildConfigField可以定义我们需要的变量，并在代码中引用。
gradle配置如下：
applicationId "com.flyscale.gradleflavor.b" //applicationId是Gradle定义好的变量 versionName "version-b-1.0" //versionName是Gradle定义好的变量 buildConfigField("String", "PRODUCT_NAME", "\"b\""); //新定义String类型变量PRODUCT_NAME，值为"b" buildConfigField("boolean", "LOG_DEBUG", "false"); //新定义boolean类型变量LOG_DEBUG,值为false
执行sync后会生成如下代码：
public final class BuildConfig { public static final boolean DEBUG = Boolean.parseBoolean("true"); public static final String APPLICATION_ID = "com.flyscale.gradleflavor.b"; public static final String BUILD_TYPE = "debug"; public static final String FLAVOR = "productB"; public static final int VERSION_CODE = 1; public static final String VERSION_NAME = "version-b-1.0"; // Fields from product flavor: productB public static final boolean LOG_DEBUG = false; public static final String PRODUCT_NAME = "b"; }
这时我们就可以在代码中调用了：
Log.d(TAG, "APPLICATION_ID=" + BuildConfig.APPLICATION_ID); Log.d(TAG, "LOG_DEBUG=" + BuildConfig.LOG_DEBUG); Log.d(TAG, "PRODUCT_NAME=" + BuildConfig.PRODUCT_NAME);
