import Want from '@ohos.app.ability.Want';
import hilog from '@ohos.hilog';

const TAG: string = 'PagePageAbilityFirst';
const domain: number = 0xFF00;

(async (): Promise<void> => {
  try {
    hilog.info(domain, TAG, 'Begin to start ability');
    let want: Want = {
      bundleName: 'com.samples.famodelabilitydevelop',
      moduleName: 'entry',
      abilityName: 'com.samples.famodelabilitydevelop.PageAbilitySingleton'
    };
    await featureAbility.startAbility({ want: want });
    hilog.info(domain, TAG, `Start ability succeed`);
  }
  catch (error) {
    hilog.error(domain, TAG, 'Start ability failed with ' + error);
  }
})()
