Starting a UIAbility from the FA Model
This topic describes how the three application components of the FA model start the UIAbility component of the stage model.
PageAbility Starting a UIAbility
A PageAbility starts a UIAbility in the same way as it starts another PageAbility.
import featureAbility from '@ohos.ability.featureAbility';
import { BusinessError } from '@ohos.base';
featureAbility.startAbility(
{
want: {
bundleName: "com.ohos.stage",
abilityName: "EntryAbility"
}
}
).then((code) => {
console.info('Ability verify code: ' + JSON.stringify(code));
}).catch((error: BusinessError) => {
console.error("Ability failed: " + JSON.stringify(error));
});
PageAbility Accessing a UIAbility (startAbilityForResult)
Different from startAbility(), startAbilityForResult() obtains the execution result when the UIAbility is destroyed.
A PageAbility starts a UIAbility through startAbilityForResult() in the same way as it starts another PageAbility through startAbilityForResult().
import featureAbility from '@ohos.ability.featureAbility';
import { BusinessError } from '@ohos.base';
featureAbility.startAbilityForResult(
{
want: {
bundleName: "com.ohos.stage",
abilityName: "com.ohos.stage.EntryAbility"
}
}).then((result) => {
console.info('Ability verify result: ' + JSON.stringify(result));
}).catch((error: BusinessError) => {
console.error("Ability failed: " + JSON.stringify(error));
});
ServiceAbility or DataAbility Starting a UIAbility
A ServiceAbility or DataAbility starts a UIAbility in the same way as it starts a PageAbility.
import particleAbility from '@ohos.ability.particleAbility';
import { BusinessError } from '@ohos.base';
particleAbility.startAbility(
{
want: {
bundleName: "com.ohos.stage",
abilityName: "com.ohos.stage.EntryAbility"
}
}
).then(() => {
console.info('Start Ability successfully.');
}).catch((error: BusinessError) => {
console.error("Ability failed: " + JSON.stringify(error));
});
