 # Using Explicit Want to Start an Ability
 
+When a user touches a button in an application, the application often needs to start a UIAbility component to complete a specific task. If the **abilityName** and **bundleName** parameters are specified when starting a UIAbility, then the explicit Want is used. Using Explicit Want
 
-When a user touches a button in an application, the application often needs to start a UIAbility component to complete a specific task. The following describes how to use explicit Want to start a UIAbility component in an application.
-
-
-## How to Develop
-
-1. In a project of the stage model, create an ability and a page, named **callerAbility** and **Index.ets**, respectively. Use the **windowStage.loadContent()** method in the **onWindowStageCreate** function in the **callerAbility.ts** file to bind the two.
-   
-   ```ts
-   // ...
-       // callerAbility.ts
-       onWindowStageCreate(windowStage) {
-           // Main window is created, set main page for this ability
-           console.info('[Demo] EntryAbility onWindowStageCreate')
-           // Bind callerAbility with a paged named Index
-           windowStage.loadContent('pages/Index')
-       }
-   // ...
-   ```
-
-2. Repeat the preceding operation to create another ability named **calleeAbility**.
-
-3. Add a button to the **Index.ets** page of **callerAbility**.
-   
-   ```ts
-   // ...
-     build() {
-       Row() {
-         Column() {
-           Text('hello')
-           .fontSize(50)
-           .fontWeight(FontWeight.Bold)
-           // A new button with will call explicitStartAbility() when clicked.
-           Button("CLICKME")
-           .onClick(this.explicitStartAbility) // For details about explicitStartAbility, see the sample code below.
-           // ...
-         }
-         .width('100%')
-       }
-       .height('100%')
-     }
-   // ...
-   ```
-
-4. Override the **onClick** method and use explicit Want to start **calleeAbility** in the method. The **bundleName** field can be obtained from the **AppScope > app.json5** file of the project. The **abilityName** field can be obtained from the **yourModuleName > src > main > module.json5** file of the corresponding module.
-   
-   ```ts
-   import common from '@ohos.app.ability.common';
-   
-   // ...
-     async explicitStartAbility() {
-       try {
-         // Explicit want with abilityName specified.
-         let want = {
-           deviceId: "",
-           bundleName: "com.example.myapplication",
-           abilityName: "calleeAbility"
-         };
-         let context = getContext(this) as common.UIAbilityContext;
-         await context.startAbility(want);
-         console.info(`explicit start ability succeed`);
-       } catch (error) {
-         console.info(`explicit start ability failed with ${error.code}`);
-       }
-     }
-   // ...
-   ```
-
-5. When you touch **CLICKME**, the corresponding page is displayed.
-
-   <img src="figures/startAbilityWtExplicitWant.PNG" alt="startAbilityWtExplicitWant" style="zoom: 80%;" />
+The user touches a button in the application to start the UIAbility component to complete a specific task. To start the UIAbility component in explicit Want mode, the **abilityName** and **bundleName** parameters must be specified. For details, see [Starting UIAbility in the Same Application](uiability-intra-device-interaction.md#starting-uiability-in-the-same-application).

 # Using Want to Share Data Between Applications
 
-
 Users often need to share data (such as a text or an image) from one application to another. The following uses PDF file sharing as an example to describe how to use Want to share data between applications.
 
+Data sharing requires two UIAbility components (one for the sharing party and the other for the shared party) and one system component (used as the application sharing box). When the sharing party initiates data sharing by calling **startAbility()**, the system implicitly matches and displays all applications that support the type of data to share. After the user selects an application, the system starts the application to complete data sharing.
 
-## Prerequisites
-
-1. There are two UIAbility components (one for the sharing party and the other for the shared party) and one system component (used as the application selector). When the sharing party initiates data sharing through **startAbility()**, the application selector is started. The system implicitly matches and displays all applications that support the type of data to share. After the user selects an application, the system starts that application to complete data sharing.
-
-2. In this section, data sharing is triggered by touching a button. You can use other ways to trigger data sharing during application development. This section focuses on the Want configuration used for data sharing.
-
-3. The following actions are involved in this section:
-   - **ACTION_SELECT (ohos.want.action.select)**: action of displaying the application selector.  
-   - **ACTION_SEND_DATA (ohos.want.action.sendData)**: action of launching the UI for sending a single data record. It is used to transfer data to the shared party.
-
-
-## How to Develop
-
-- Sharing party
-  1. In the stage mode, the [File Descriptor (FD)](../reference/apis/js-apis-fileio.md#fileioopensync) is used for file transfer. This example assumes that the path of the file to share is obtained.
-     
-      ```ts
-      import fileIO from '@ohos.fileio';
-      
-      // let path = ...
-      // Open the file whose path is a variable.
-      let fileFd = fileIO.openSync(path, 0o102, 0o666);
-      ```
-      
-  2. As described in the prerequisites, the sharing party starts an application selector and shares the data to the selector, and the selector transfers the data to the shared party. Want of the sharing party must be nested at two layers. At the first layer, implicit Want is used together with the **ohos.want.action.select** action to display the application selector. At the second layer, complete Want is declared in the custom field **parameters** to transfer the data to share.
-     
-      ```ts
-      import wantConstant from '@ohos.app.ability.wantConstant';
-      
-      // let path = ...
-      // let fileFd = ...
-      // let fileSize = ...
-      let want = {
-          / This action is used to implicitly match the application selector.
-          action: wantConstant.Action.ACTION_SELECT,
-          // This is the custom parameter in the first layer of Want,
-          / which is intended to add information to the application selector.
-          parameters: {
-              // MIME type of PDF.
-              "ability.picker.type": "application/pdf",
-              "ability.picker.fileNames": [path],
-              "ability.picker.fileSizes": [fileSize],
-              // This nested Want ,which will be directly sent to the selected application.        
-              "ability.want.params.INTENT": {
-                  "action": "ohos.want.action.sendData",
-                  "type": "application/pdf",
-                  "parameters": {
-                     "keyFd": {"type": "FD", "value": fileFd}
-                  }
-              }
-          }
+In this section, data sharing is triggered by touching a button. You can use other ways to trigger data sharing during application development. This section focuses on how to configure Want to implement data sharing.
+
+The following actions are involved for data sharing:
+
+- **ohos.want.action.select**: action of starting the application sharing box.
+- **ohos.want.action.sendData**: action of sending a single data record, that is, transferring data to the shared party.
+
+## Sharing Party
+
+The sharing party starts an application sharing box and transfers the data to the shared party. Therefore, Want of the sharing party must be nested at two layers. In the first layer, implicit Want is used together with the **ohos.want.action.select** action to display the application sharing box. In the second layer, the data to share is declared
+
+in the custom field **parameters**, and then the Want that includes the **ohos.want.action.sendData** action and the **parameters** field is transferred to the application sharing box. The shared party obtains the shared data from **parameters**.
+
+```ts
+import common from '@ohos.app.ability.common';
+
+let fileType = 'application/pdf';
+let fileName = 'TestFile.pdf';
+let fileFd = -1; // Obtain the file descriptor (FD) of the file to share.
+let fileSize; // Obtain the size of the file to share.
+
+function implicitStartAbility() {
+  let context = getContext(this) as common.UIAbilityContext;
+  let wantInfo = {
+    / This action is used to implicitly match the application sharing box.
+    action: 'ohos.want.action.select',
+    // This is the custom parameter in the first layer of Want,
+    / which is intended to add information to the application sharing box.
+    parameters: {
+      // MIME type of PDF.
+      'ability.picker.type': fileType,
+      'ability.picker.fileNames': [fileName],
+      'ability.picker.fileSizes': [fileSize],
+      // This is nested Want ,which will be directly sent to the selected application.
+      'ability.want.params.INTENT': {
+        'action': 'ohos.want.action.sendData',
+        'type': 'application/pdf',
+        'parameters': {
+          'keyFd': { 'type': 'FD', 'value': fileFd }
+        }
       }
-      ```
-
-      In the preceding code, the custom field **parameters** is used. The **ability.picker.\*** fields in the first-layer **parameters** are used to pass the information to be displayed on the application selector. The following fields are involved:
-
-      - **"ability.picker.type"**: The application selector renders the file type icon based on this field.
-      - **"ability.picker.fileNames"**: The application selector displays the file name based on this field.
-      - **"ability.picker.fileSizes"**: The application selector displays the file size based on this field. The unit is byte.
-      - **"ability.picker.fileNames"** and **"ability.picker.fileSizes"** are arrays and have a one-to-one mapping.
-
-      For example, when **"ability.picker.type"** is **"application/pdf"**, **"ability.picker.fileNames"** is **"["APIs.pdf"]"**, and **"ability.picker.fileSizes"** is **"[350 \* 1024]"**, the application selector is displayed as follows:
-
-      ![stage-want2](figures/stage-want2.png)
-      
-      In the preceding code, the **ability.want.params.INTENT** field is nested Want. In this field, **action** and **type** are used for implicit matching by the application selector. For details about implicit matching, see [Matching Rules of Implicit Want](explicit-implicit-want-mappings.md#matching-rules-of-implicit-want). After the user selects an application, the nested Want of the **ability.want.params.INTENT** field is passed to that application.
-  
-- Shared party
-  1. As mentioned above, the application selector performs implicit matching based on the **ability.want.params.INTENT** field. Therefore, you must set **skills** in the ability configuration file (**module.json5** file in the stage model) of the shared party as follows:
-     
-      ```ts
-      "skills": [
-        {
-          "entities": [
+    }
+  }
+  context.startAbility(wantInfo).then(() => {
+    // ...
+  }).catch((err) => {
+    // ...
+  })
+}
+```
+
+> **NOTE**
+>
+> Data sharing can be implemented only in FD format. For details about how to obtain the FD and file name, see [File Management](../reference/apis/js-apis-file-fs.md).
+
+In the preceding code, under the custom field **parameters**, the following **ability.picker.*** fields are used to pass the information to be displayed on the application sharing box:
+
+- **ability.picker.type**: file type icon.
+- **ability.picker.fileNames**: file name.
+- **ability.picker.fileSizes**: file size, in bytes.
+- **ability.picker.fileNames** and **ability.picker.fileSizes** are arrays and have a one-to-one mapping.
+
+The following figure shows an example. 
+
+![stage-want2](figures/stage-want2.png)
+
+## Shared Party
+
+To enable the shared party to identify the shared content, configure **skills** in the [module.json5 file](../quick-start/module-configuration-file.md) of the UIAbility of the shared party. The **actions** and **type** fields in **uris** match the **action** and **type** fields in **ability.want.params.INTENT** of the sharing party, respectively.
+
+```json

+  "module": {
+    // ...

+              "action.system.home",
               "ohos.want.action.sendData"

-
-      The **actions** and **type** fields in **uris** match the **action** and **type** fields in **ability.want.params.INTENT**, respectively.
-
-      Files can be transferred in FD mode, but not URI mode. In implicit matching, the **type** field in Want must match the **type** field in **uris** under **skills** of the shared party. Therefore, specify only the **type** field in **uris**. If **host** and **port** are specified, the matching fails. The application selector initiates implicit matching based on **ability.want.params.INTENT**. Therefore, when the **uri** field added to **ability.want.params.INTENT** matches the **uris** field under **skills**, the matching is successful and additional data can be transferred.
-  2. After the application selector starts the shared party, the system calls **onCreate** and passes **ability.want.params.INTENT** to the **want** parameter.
-     
-      ```ts
-      onCreate(want, launchParam) {
-        // When keyFd is undefined, the application crashes.
-        if (want["parameters"]["keyFd"] !== undefined) {
-          // Receive the file descriptor.
-          let fd = want["parameters"]["keyFd"].value;
-          // ...
-        }
+            ],

+              {

+          }
+        ]
       }
-      ```
+    ]
+  }
+}
+```
+
+After the user selects an application, the Want nested in the **ability.want.params.INTENT** field is passed to that application. The UIAbility of the shared party, after being started, can call [onCreate()](../reference/apis/js-apis-app-ability-uiAbility.md#uiabilityoncreate) or [onNewWant()](../reference/apis/js-apis-app-ability-uiAbility.md#uiabilityonnewwant) to obtain the passed Want.
+

+

Each time [startAbility()](../reference/apis/js-apis-inner-application-uiAbilityContext.md#uiabilitycontextstartability) is called, the application is asked which UIAbility instance is used to respond to the [startAbility()](../reference/apis/js-apis-inner-application-uiAbilityContext.md#uiabilitycontextstartability) request.
-   In EntryAbility, add a custom parameter, for example, **instanceKey**, to the [want](want-overview.md) parameter in [startAbility()](../reference/apis/js-apis-inner-application-uiAbilityContext.md#uiabilitycontextstartability) to distinguish the UIAbility instances.

-   For example, in the document application, different key values are bound to different document instances. Each time a document is created, a new key value (for example, file path) is passed, and a new UIAbility instance is created when UIAbility is started in AbilityStage. However, when you open an existing document, the same UIAbility instance is started again in AbilityStage.
