#鸿蒙通关秘籍#如何在鸿蒙中实现组件的手动启动模式？

如果某些组件不需要在应用启动前初始化，可以使用手动启动模式。在应用启动后，通过在StartupManager中调用run方法启动。这可以在生命周期如onCreate中进行如下设置： bash import { AbilityConstant, UIAbility, Want, startupManager } from '@kit.AbilityKit'; import { hilog } from '@kit.PerformanceAnalysisKit'; import { BusinessError } from '@kit.BasicServicesKit';

export default class EntryAbility extends UIAbility { onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void { hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onCreate'); let startParams = ['StartupTask_005', 'StartupTask_006']; try { startupManager.run(startParams).then(() => { console.log('StartupTest startupManager run then, startParams = '); }).catch((error: BusinessError) => { console.info("StartupTest promise catch error, error = " + JSON.stringify(error)); console.info("StartupTest promise catch error, startParams = " + JSON.stringify(startParams)); }) } catch (error) { let errMsg = JSON.stringify(error); let errCode: number = error.code; console.log('Startup catch error , errCode= ' + errCode); console.log('Startup catch error ,error= ' + errMsg); } }

// ... }
