1.startAbility 打开新的UIAbility

 private context = getContext(this) as common.UIAbilityContext;
this.context.startAbility({
bundleName: ‘包名’,
abilityName: ‘Ability名’
}).then(() => {
Logger.info( ‘start LoginAbility success’)
}).catch((error:BusinessError) => {
Logger.error( ‘start LoginAbility failed, error: ’ + error.code)
})<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>

问题：同一个应用会存在两个任务

2.命名路由文档

import(’@ohos/library/src/main/ets/pages/Index’);  // 引入共享包中的命名路由页面

try {
router.pushNamedRoute({
name: ‘myPage’,
params: {
data1: ‘message’,
data2: {
data3: [123, 456, 789]
}
}
})
} catch (err) {
let message = (err as BusinessError).message
let code = (err as BusinessError).code
console.error(pushNamedRoute failed, code is ${code}, message is ${message});
}<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>

目标包需要在@Entry后添加命名

@Entry({ routeName: ‘myPage’ })<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>

问题：跳转hap包后路由失效。

3.跨模块路由跳转文档

'@bundle:包名（bundleName）/模块名（moduleName）/路径/页面所在的文件名(不加.ets后缀)'<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>

问题：跳转hap包后闪退 返回errcode 1
