+# 资源管理changeLog
+
+## cl.resourceManager.1  资源API9部分多工程接口命名变更
+
+资源管理从API9开始提供接口的错误码和错误信息返回，涉及API9提供的部分多工程接口需要适配。从API9开始作以下变更：
+
+资源API部分多工程接口需要用新的接口替换，参数不变。
+
+**变更影响**
+
+基于此前版本开发的应用，涉及下面多工程接口的JS接口需要替换为新的接口。
+
+**关键接口/组件变更**
+
+| **涉及接口**                            | **对应替换接口** |
+| ----------------                         | ------------ |
+| getString(resource: Resource, </br>callback: AsyncCallback\<string>): void;   | getStringValue(resource: Resource, </br>callback: AsyncCallback\<string>): void;       |
+| getString(resource: Resource): Promise\<string>;   | getStringValue(resource: Resource): Promise\<string>;       |
+| getStringArray(resource: Resource, </br>callback: AsyncCallback\<Array\<string>>): void;    | getStringArrayValue(resource: Resource, </br>callback: AsyncCallback\<Array\<string>>): void;       |
+| getStringArray(resource: Resource): Promise\<Array\<string>>;    | getStringArrayValue(resource: Resource): Promise\<Array\<string>>;       |
+| getMedia(resource: Resource, </br>callback: AsyncCallback\<Uint8Array>): void;    | getMediaContent(resource: Resource, </br>callback: AsyncCallback\<Uint8Array>): void;       |

+| getPluralString(resource: Resource, num: number, </br>callback: AsyncCallback<string>): void;   | getPluralStringValue(resource: Resource, num: number, </br>callback: AsyncCallback\<string>): void;       |
+| getPluralString(resource: Resource, num: number): Promise\<string>;   | getPluralStringValue(resource: Resource, num: number): Promise\<string>;       |
+
+**适配指导**
+
+以getMedia修改为getMediaContent的callback调用为例，其promise方式类似，只需修改函数名，且增加错误码和错误信息返回，其它不变。示例代码如下：
+
+- 变更前：getMedia(resource: Resource, callback: AsyncCallback<Uint8Array>): void;
+```ts
+let resource = {
+    bundleName: "com.example.myapplication",
+    moduleName: "entry",
+    id: $r('app.media.test').id
+};
+this.context.resourceManager.getMedia(resource, (error, value) => {
+    if (error != null) {
+      console.log("error is " + error);
+    } else {
+      let media = value;
+    }
+});
+```
+
+- 变更后：getMediaContent(resource: Resource, callback: AsyncCallback<Uint8Array>): void;
+```ts
+let resource = {
+    bundleName: "com.example.myapplication",
+    moduleName: "entry",
+    id: $r('app.media.test').id
+};
+try {
+  this.context.resourceManager.getMediaContent(resource, (error, value) => {
+      if (error != null) {
+        console.log("error is " + error);
+      } else {
+        let media = value;
+      }
+  });
+} catch (error) {
+  console.error(`callback getMediaContent failed, error code: ${error.code}, message: ${error.message}.`)
+}
+```
