在开发OpenHarmony的时候，经常遇到需要把所有测试功能的hap做成一个hap的需求。显然如果一个hap内集成所有测试hap的方案需要花费较大时间成本且各个测试hap之间api并不统一。这里采用应用间跳转的方式。

实现思路

1.这里采用指定Ability方式（即显式Want）拉起其他应用方式。

import Want from '@ohos.app.ability.Want';
import common from '@ohos.app.ability.common';
import { hilog } from '@kit.PerformanceAnalysisKit';
import { BusinessError } from '@ohos.base';

@Entry
@Component
struct Index {
  context = getContext(this) as common.UIAbilityContext;
  navPathStack: NavPathStack = new NavPathStack();

  @Styles
  commonButton() {
    .width(250)
    .margin(5)
  }

  build() {
    Navigation(this.navPathStack) {
      Column() {
        Text('通过startAbility拉起：')

        Button('跳转系统相机')
          .onClick(() => {
            let want: Want = {
              bundleName: 'com.ohos.camera',
              abilityName: 'com.ohos.camera.MainAbility',
            };
            this.context.startAbilityForResult(want).then((data) => {
              hilog.info(0x0000, 'Success', JSON.stringify(data))
            }).catch(() => {
              hilog.info(0x0000, 'error', '')
            })
          })
          .commonButton()

        Button('跳转系统设置wifi页面')
          .onClick(() => {
            let want: Want = {
              bundleName: 'com.ohos.settings',
              abilityName: 'com.ohos.settings.MainAbility',
              uri: 'wifi', // 对应wifi设置页，不传就跳转系统设置首页/当前所在页
            };
            this.context.startAbility(want).then(() => {
            }).catch((err: BusinessError) => {
              hilog.error(0x0000, 'Failed to startAbility. Code:', `${err.code}${err.message}`);
            });
          })
          .commonButton()

        Button('跳转系统设置蓝牙页面')
          .onClick(() => {
            let want: Want = {
              bundleName: 'com.ohos.settings',
              abilityName: 'com.ohos.settings.MainAbility',
              uri: 'bluetooth', // 对应wifi设置页，不传就跳转系统设置首页/当前所在页
            };
            this.context.startAbility(want).then(() => {
            }).catch((err: BusinessError) => {
              hilog.error(0x0000, 'Failed to startAbility. Code:', `${err.code}${err.message}`);
            });
          })
          .commonButton()

        Button('跳转系统音乐应用')
          .onClick(() => {
            let want: Want = {
              bundleName: 'ohos.samples.distributedmusicplayer',
              abilityName: 'ohos.samples.distributedmusicplayer.MainAbility',
              uri: 'bluetooth', // 对应wifi设置页，不传就跳转系统设置首页/当前所在页
            };
            this.context.startAbility(want).then(() => {
            }).catch((err: BusinessError) => {
              hilog.error(0x0000, 'Failed to startAbility. Code:', `${err.code}${err.message}`);
            });
          })
          .commonButton()

      }
      .width('100%')
      .height('100%')
    }
    .title('拉起系统及三方应用')
  }
