我有幾個待處理的意圖，我想在廣播接收器引導操作運行時創建。每個意圖在給定的時間發出警報。我能夠在一項活動中做到這一點，但它並不適用於某項服務。待處理意圖報警不能在後臺服務中工作
這很奇怪，因爲logcat顯示數據正在處理到for循環和函數中，但是當滿足時間時鬧鐘不會關閉。
你可以看看我的代碼，讓我知道我失蹤了嗎？

我改變了這一行：sender = PendingIntent.getService（AlarmsService.this.getApplicationContext（），id，osa，0）;並沒有奏效。你有什麼其他的建議？ – Leoa
您是否嘗試使用意向開始服務？ startService（osa），檢查意圖是否正確？ – nandeesh
也檢查編輯。 – nandeesh
