Android Gradle配置Debug和release参数的方法

方法一:使用BuildConfig类修改参数值

Gradle Android自带BuildConfig配置类,在build工程的时候,可以在build/generated/source/buildConfig下的debug和release路径下找到。

BuildConfig.java类可以在工程中引用;

BuildConfig.java自带DEBUG参数,在打包debug版本的时候,DEBUG = true,在打包release版本的时候,DEBUG=false;

如何自定义BuildConfig参数呢?使用buildConfigField进行配置:
    

buildTypes {
    debug {
        buildConfigField "String", "CustomValue",'"buildType"'
        buildConfigField "boolean","LOG_DEBUG","true"
    }
    release {
        buildConfigField "String", "CustomValue",'"releaseType"'
        buildConfigField "boolean","LOG_DEBUG","false"
    }
}


   注:buildConfigField 配置格式为: "type","name","value" 形式,如果参数是String类型,"value"外部需加单引号申明内部是String类型的,或者使用转移符 \ ,如:

"\"buildType\""

这样在build 工程的时候,    生成的BuildConfig.java中就包含了这些参数:

public final class BuildConfig {
public static final boolean DEBUG = false;
  public static final String APPLICATION_ID = "com.xxx.xxxx";
  public static final String BUILD_TYPE = "release";
  public static final String FLAVOR = "";
  public static final int VERSION_CODE = 1002;
  public static final String VERSION_NAME = "1002";
  // Fields from build type: release
  public static final String CustomValue = "releaseType";
}

 

最后,在代码中赋值:


/** 是否开发模式 */
private static final boolean isDebug = BuildConfig.DEBUG;

 

方法二:使用AndroidManifest.xml中的meta-data

    在AndroidManifest.xml中申明meta-data参数,注意value的语法

    android:name="Logs.enable"
    android:value="${LogEnable}"/>

然后在gradle中配置buildTypes;

buildTypes {
    debug {
manifestPlaceholders = [LogEnable : true]
    }
    release {
manifestPlaceholders = [LogEnable : false]
    }
}

最后在工程代码中加载meta-data的数据

ApplicationInfo appInfo = null;
try {
   appInfo = this.getPackageManager()
                  .getApplicationInfo(getPackageName(),
                          PackageManager.GET_META_DATA);
   boolean enable=appInfo.metaData.getBoolean("Logs.enable");
   Log.d("MyApplication","Logs.enable = "+enable);
} catch (PackageManager.NameNotFoundException e) {
   e.printStackTrace();
}
