conf.gradle

在项目根目录下新建conf.gradle文件，在其中写项目的通用配置

project build.gradle

在项目的build.gradle中引用配置文件

apply from: "conf.gradle"
buildscript 
    ext.kotlin_version = "1.3.72"
	……
    dependencies 
    	classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"    
    

module build.gradle

在模块的build.gradle中使用配置文件

def conf = rootProject.ext //指向conf.gradle的根标签ext

AndroidManifest.xml

在AndroidManifest.xml中配置build.gradle中的参数

<application
    android:icon="$icon"
    android:label="@string/app_name"
    android:roundIcon="$roundIcon"
    tools:replace="name,icon,roundIcon">
     <!--渠道名称-->
     <meta-data
         android:name="channel_name"
         android:value="$channel_name" />
    <!--配置的key-->
     <meta-data
         android:name="xxx_key"
         android:value="$xxx_key" />
</application>

Java.class

在java类中使用build.gradle中的配置参数

//调用在AndroidManifest.xml中的meta-data标签
PackageManager packageManager = application.getPackageManager();
ApplicationInfo applicationInfo = packageManager.getApplicationInfo(application.getPackageName(), PackageManager.GET_META_DATA);
Bundle bundle = applicationInfo.metaData;
String xxx_key = bundle.getString("xxx_key");

//java预编译
public final class BuildConfig 
  public static final boolean DEBUG = Boolean.parseBoolean("true");
  public static final String LIBRARY_PACKAGE_NAME = "yoobingo.yiji.main";
  public static final String BUILD_TYPE = "debug";
  public static final int VERSION_CODE = 120;
  public static final String VERSION_NAME = "qyqx_V1.2.0";

//调用
String versionName = BuildConfig.VERSION_NAME;
