AndroidStudio多渠道打包build.gradle设置

对应Manifest文件中的Umeng渠道

<meta-data android:name="UMENG_CHANNEL"android:value="${UMENG_CHANNEL_VALUE}" />

注意UMENG_CHANNEL_VALUE前后的是大括号{}

AndroidStudio3.0上进行多渠道打包必须指定一种 flavor dimensions

flavorDimensions "default"
  productFlavors {
    HuanStore {
      dimension "default"
    }
    huanhelper {
      dimension "default"
    }
    tvhuan {
      dimension "default"
    }
    dangbei {
      dimension "default"
    }
  }

  productFlavors.all {
    flavor -> flavor.manifestPlaceholders = [UMENG_CHANNEL_VALUE: name]
  }

获取meta-data的value

//通过ApplicationInfo获取meta-data标签中指定name对应的value
private String getMetaValue(String name) {
       String value = null;
        try {
            ApplicationInfo appInfo = this.getPackageManager()
                .getApplicationInfo(getPackageName(), PackageManager.GET_META_DATA);
        
            value = appInfo.metaData.getString(name);
            Log.d(TAG,name + "-->" + value);
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return value;
}

通过ActivityInfo获取
ActivityInfo info = this.getPackageManager()
                .getActivityInfo(getComponentName(),PackageManager.GET_META_DATA);
  info.metaData.getString("meta_name");

通过ServiceInfo获取
ComponentName cn = new ComponentName(this, MetaDataService.class);
 ServiceInfo info = this.getPackageManager().getServiceInfo(cn, PackageManager.GET_META_DATA);
 info.metaData.getString("meta_name");

通过ReceiverInfo获取
ComponentName cn = new ComponentName(context, MetaDataReceiver.class);
ReceiverInfo info = context.getPackageManager().getReceiverInfo(cn, PackageManager.GET_META_DATA);
info.metaData.getString("meta_name");
