1. UIAbility 的添加和设置启动(相当于微信里的微信小程序，从最近任务打开，可以切换是聊天还是操作小程序)

14.4设置主启动Ability

    "exported": true,
        "skills": [
          {
            "entities": [
              "entity.system.home"
            ],
            "actions": [
              "action.system.home"
            ]
          }
        ]

14.4 UIAbility 组件的生命周期

import { AbilityConstant, UIAbility, Want } from '@kit.AbilityKit';
import { hilog } from '@kit.PerformanceAnalysisKit';
import { window } from '@kit.ArkUI';

export default class ApplicationAbility extends UIAbility {
  onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void {
    hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onCreate');
  }

  onDestroy(): void {
    hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onDestroy');
  }

  onWindowStageCreate(windowStage: window.WindowStage): void {
    // Main window is created, set main page for this ability
    hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onWindowStageCreate');

    windowStage.loadContent('pages/Index', (err) => {
      if (err.code) {
        hilog.error(0x0000, 'testTag', 'Failed to load the content. Cause: %{public}s', JSON.stringify(err) ?? '');
        return;
      }
      hilog.info(0x0000, 'testTag', 'Succeeded in loading the content.');
    });
  }

  onWindowStageDestroy(): void {
    // Main window is destroyed, release UI related resources
    hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onWindowStageDestroy');
  }

  onForeground(): void {
    // Ability has brought to foreground
    hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onForeground');
  }

  onBackground(): void {
    // Ability has back to background
    hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onBackground');
  }
}

14.3配置-启动页配置

14.4 同模块唤醒Ability

 context = getContext(this) as common.UIAbilityContext        

 // 1. 准备 want (参数信息)
            let wantInfo: Want = {
              deviceId: '', // 空表示本设备
              bundleName: 'com.example.part4demo', // AppScope/app.json 确认
              moduleName: 'entry', // 模块名
              abilityName: 'TwoAbility', // src/main/module.json5
              parameters: {
                info: '来自entryAbility'
              }
            }
            // 2. 利用context startAbility 调起 UIAbility
            //    返回一个promise对象
            this.context.startAbility(wantInfo)
              .then(() => {
                console.log('startAbility 成功')
              })
              .catch((error: BusinessError) => {
                console.log('启动Ability 失败', error)
              })

14.5 不同模块唤醒Ability

 context = getContext(this) as common.UIAbilityContext
      
    // 1. 准备 want (参数信息)
            let wantInfo: Want = {
              deviceId: '', // 空表示本设备
              bundleName: 'com.example.part4demo', // AppScope/app.json 确认
              moduleName: 'TestModule', // 模块名
              abilityName: 'TestModuleAbility', // src/main/module.json5
              parameters: {
                info: '来自entryAbility'
              }
            }
            // 2. 利用context startAbility 调起 UIAbility
            //    返回一个promise对象
            this.context.startAbility(wantInfo)
              .then(() => {
                console.log('startAbility 成功')
              })
              .catch((error: BusinessError) => {
                console.log('启动Ability 失败', error)
              })
