HarmonyOS 申请短时后台任务闪退？

Question

申请短时后台任务闪退，日志如下

or message:BussinessError 9900002: Transient task verification failed. The remaining time to run transient task is insufficient.
Error code:9900002
SourceCode:
  let delayInfo = backgroundTaskManager.requestSuspendDelay(myReason, () => {
    ^

怎么查询24小时内剩余配额时间

Answer 1

关于 9900002 的报错请参看文档检查： https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/errorcode-backgroundtaskmgr-V5\#section9900002-短时任务校验失败

获取短时任务剩余时间

let id: number; // 申请短时任务ID

async function getRemainingDelayTime() {
  backgroundTaskManager.getRemainingDelayTime(id).then((res: number) => {
    console.info('Succeeded in getting remaining delay time.');
  }).catch((err: BusinessError) => {
    console.error(`Failed to get remaining delay time. Code: ${err.code}, message: ${err.message}`);
  })
}

没有api可以查询24小时整体剩余配额时间，可以在backgroundTaskManager.requestSuspendDelay时加上try catch 捕捉错误提示，来判断是否超额
