在module.json5文件中配置HarmonyOS轻量地图SDK所需的相关权限，确保SDK可以正常使用。配置如下：

"requestPermissions": [
        {
          "name": "ohos.permission.WRITE_USER_STORAGE"
        },
        {
          "name": "ohos.permission.READ_USER_STORAGE"
        },
        {
          "name": "ohos.permission.INTERNET"
        },
        {
          "name": "ohos.permission.GET_BUNDLE_INFO"
        }

]

在工程的oh-package.json5文件中添加依赖。配置如下：

{
    "license": "Apache License 2.0",
    "devDependencies": {},
    "name": "entry",
    "description": "example description",
    "version": "1.0.1",
    "dependencies": {
    //添加依赖如下
      "@bdmap/base": "1.0.0",
      "@bdmap/search": "1.0.0",
      "@bdmap/map": "1.0.0"
    }
}

在Ability中调用如下代码来获取appIdentifier：

/**
    * 获取appIdentifier
    */
    public getBundleAppIdentifier() {
      // 根据给定的bundle名称获取BundleInfo。 
      // 使用此方法需要申请 ohos.permission.GET_BUNDLE_INFO权限。 
      let bundleFlags = bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_SIGNATURE_INFO;
      try {
        return bundleManager.getBundleInfoForSelf(bundleFlags).then((data) => {
        //获取appIdentifier 
          appIdentifier = data.signatureInfo.appIdentifier;
          console.info('getBundleAppIdentifier successfully. Data: ' + appIdentifier );
        }).catch(error => {
          console.error('getBundleAppIdentifier failed. Cause: ' + error.message);
        });
      } catch (error) {
        console.error('getBundleAppIdentifier failed:' + error.message);
      }
    }
