HarmonyOS/OpenHarmony应用开发-stage使用显示Want启动Ability

import context from '@ohos.application.context';
@Entry
@Component
struct Index {
  @State message: string = '第一个Ability的page'


  build() {
    Row() {
      Column() {
        Text(this.message)
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
        Button("CLICKME")
          .onClick(this.explicitStartAbility)
      }
      .width('100%')
    }
    .height('100%')
  }
  async explicitStartAbility() {
    try {
      let want = {
        deviceId: "",
        bundleName: "com.example.want_demo",
        abilityName: "EntryAbility1"
      };
      let context = getContext(this) as context.AbilityContext;
      await context.startAbility(want);
      console.info(`explicit start ability succeed`);
    } catch (err) {
      console.info(`explicit start ability failed with ` + err.code);
    }
  }
}
