Huawei HarmonyOS designed the latest guide for developing ongoing back-end tasks to help developers gain a better understanding of the necessity and operational steps involved in applying for recent tasks. The guide presents clear concepts and a structured format, outlining specific usage scenarios and detailed development steps.
If an app stays active after it retreats to the back end, it may cause issues such as rapid battery consumption and lag in the HarmonyOS. To address these issues and guarantee a seamless user experience, the system actively handles applications that return to the back end, utilizing processes like suspension and termination. As a result, developers must take into account factors such as real-time requirements and time consumption when choosing an appropriate back-end running task type.
Based on the function introduction, developers can opt for short-term tasks to fulfill high real-time requirements and quick consumption, long-term tasks for applications running in the back end for an extended period and are user-perceivable, delayed tasks for non-real-time performance needs, and proxy reminders for scheduled reminder services. In terms of operation, developers must comprehend similar mechanisms technology, and features for efficient development. They should import relevant modules to apply for short-term tasks and implement callbacks. Simultaneously, developers can query the remaining time to decide whether to continue running other services.
Upon completing the operation, it is crucial to promptly cancel the short-term task and be mindful of the quota mechanism and calculation method to prevent any impact on the application’s remaining quota for short-term tasks on the day. This series of guides and operational steps empower developers to flexibly utilize back-end running tasks to meet diverse needs and guarantee the seamless operation of applications.
