在开发过程中,需捕获和处理启动框架的异常问题,尤其是在调用StartupManager.run时。通过捕获异常,方便调试与解决问题,以下示例提供了异常处理的基础结构: 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 { let startParams = ['StartupTask_005', 'StartupTask_006']; try { startupManager.run(startParams).then(() => { console.log('StartupManager run completed successfully'); }).catch((error: BusinessError) => { console.log('Error during startup: ' + JSON.stringify(error)); }); } catch (error) { let errorMessage = JSON.stringify(error); let errorCode: number = error.code; console.log('Startup caught an error, code: ' + errorCode); console.log('Error message: ' + errorMessage); } } }
