Android：意圖服務

我試圖通過在intentservice類中實現它來使用Fused位置提供程序API來獲取位置，同時我正在同一服務中啓動一個newtimertask。Android：意圖服務

因此，當intentservice被調用時，timertask開始並且googleapiclent被連接到獲取位置。

我希望如果位置不可用，我的時間任務將在60秒內斷開googleapiclient。

但是這不起作用...如果它沒有得到位置...意圖服務繼續運行或fusedlocatinprovider保持尋找location.so我必須停止這些？

} }時onHandleIntent（）結束，如果沒有更多的命令已被髮送給它而onHandleIntent

您可以將Intent-Service轉移或更改爲Service，並使用stopSelf（）方法停止服務。此方法會停止服務。

我不必使用服務 – Rumour

@Rumour不，你**有**使用服務 – pskink

但那會阻止我的用戶界面...因爲服務在UI線程上運行 – Rumour

IntentService自動停止本身（）是在運行。因此，您不要自己手動停止IntentService。

但是，這會使我的用戶界面無響應 – Rumour

進一步我必須基本註銷googelapiclient ........... – Rumour
