HarmonyOS鸿蒙Next中Ability互相拉起，执行this.context.startAbility一直报错TypeError: is not callable

在HarmonyOS鸿蒙Next中，Ability互相拉起时，如果执行this.context.startAbility报错TypeError: is not callable，通常是因为this.context未正确获取或未正确初始化。确保在Ability的onCreate生命周期中正确获取了context对象。例如：

import Ability from '@ohos.application.Ability';

export default class MainAbility extends Ability {
    onCreate(want, launchParam) {
        console.log("MainAbility onCreate");
        // 确保context对象正确获取
        this.context = this.context;
    }
}

如果this.context未正确初始化，调用startAbility时会出现TypeError。另外，检查startAbility的参数是否符合要求，如want对象是否正确配置。例如：

let want = {
    bundleName: "com.example.myapplication",
    abilityName: "com.example.myapplication.MainAbility"
};

this.context.startAbility(want).then(() => {
    console.log("Start ability success");
}).catch((err) => {
    console.error("Start ability failed: " + err);
});

确保want对象中的bundleName和abilityName正确无误。如果问题依旧，检查Ability的声明和配置是否正确。
