Look at the generated BuildConfigclass.
查看生成的BuildConfig类。
public final class BuildConfig {
public static final boolean DEBUG = Boolean.parseBoolean("true");
public static final String APPLICATION_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 = "";
}

Another option would be to create a separate build config variable for each build variant and use it in your code like this:
另一种选择是为每个构建变体创建一个单独的构建配置变量，并在您的代码中使用它，如下所示：
In your build.gradle file:
在您的 build.gradle 文件中：
productFlavors {
production {
buildConfigField "String", "BUILD_VARIANT", "\"prod\""
}
dev {
buildConfigField "String", "BUILD_VARIANT", "\"dev\""
}
}
To use it in your code:
要在您的代码中使用它：
if (BuildConfig.BUILD_VARIANT.equals("prod")){ // do something cool }

You can try with
你可以试试
getPackageName();
it will return what you've defined in build.gradle
它将返回您在 build.gradle 中定义的内容
productFlavours{
flavour1{
applicationId 'com.example.package.flavour1'
}
flavour2{
applicationId 'com.example.package.flavour2'
}
}

Here is an example to define and get BuildConfigfor different flavor
这是定义和获取BuildConfig不同风味的示例
android {
defaultConfig {
...
buildTypes {
...
}
flavorDimensions "default"
productFlavors {
develop {
applicationIdSuffix ".dev"
versionNameSuffix "-dev"
}
staging {
applicationIdSuffix ".stg"
versionNameSuffix "-stg"
}
production {
applicationIdSuffix ""
versionNameSuffix ""
}
}
applicationVariants.all { variant ->
def BASE_URL = ""
if (variant.getName().contains("develop")) {
BASE_URL = "https://localhost:8080.com/"
} else if (variant.getName().contains("staging")) {
BASE_URL = "https://stagingdomain.com/"
} else if (variant.getName().contains("production")) {
BASE_URL = "https://productdomain.com/"
}
variant.buildConfigField "String", "BASE_URL", "\"${BASE_URL}\""
}
}
Using
使用
BuildConfig.BASE_URL
BuildConfig.BASE_URL

If you are already flavoring then no need to provide extra string field in your gradle. Just follow simple steps to get the build details:
如果您已经在调味，那么无需在您的 gradle 中提供额外的字符串字段。只需按照简单的步骤即可获取构建详细信息：
For build variant : BuildConfig.FLAVOR
For build version code : BuildConfig.VERSION_CODE
For build version name : BuildConfig.VERSION_NAME
对于构建变体：BuildConfig.FLAVOR
对于构建版本代码：BuildConfig.VERSION_CODE
对于构建版本名称：BuildConfig.VERSION_NAME
