77      {
78        "name": "TargetAbility",
79        ......
80        "exported": true,
81        "skills": [
82          {

1002. Implicitly start the ability.
101
102    - Run the **-U** command to start an application page.

112        ```
113
114      The following is an example for the UIAbility to obtain input parameters:
115  
116        ```ts
117        import UIAbility from '@ohos.app.ability.UIAbility';
118        import hilog from '@ohos.hilog';
119        import Want from '@ohos.app.ability.Want';
120
121        export default class TargetAbility extends UIAbility {
122          onCreate(want:Want, launchParam) {
123            hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onCreate');
124            let paramNumber = want.parameters.paramNumber
125            let paramBoolean = want.parameters.paramBoolean
126            let paramString = want.parameters.paramString
127            let paramNullString = want.parameters.paramNullString
128          }
129        }
130        ```
131
132    - Run the **-A -U** command to start the browser and redirect to a specified page.
133
134      The following uses **https://www.example.com** as an example. Replace it with the actual URL.
135
136        ```bash
137        aa start -A ohos.want.action.viewData -U https://www.example.com

293## appdebug
294  Sets or cancels the waiting-for-debugging state of an application, and obtains the bundle name and persistence flag of an application in the waiting-for-debugging state. The waiting-for-debugging state takes effect only for debugging applications. The setting command of **appdebug** takes effect only for a single application. Once the command is executed repeatedly, the bundle name and persistence flag are replaced with the latest settings.

308  **Method**
309
310  ```bash
311  # Display the help information.
