我試圖在鎖屏上顯示Activity。顯示Activity片刻，然後崩潰。這隻發生在特定設備上（索尼Xperia Z2），該應用在各種其他設備上運行得非常好。Android onPause（）在onStop（）後調用
根據記錄，onPause()被onStop()後稱爲：

我絕望，沒有人知道爲什麼會出現這種情況？
在調用第二個函數時終止未處理的線程執行。 – jasim 2014-10-28 15:59:18
我試過了，它不是唯一導致這個問題的東西。我會發布答案。 – Smuggler 2014-10-28 16:54:59
在onStop（）和onPause（）中記錄Activity的上下文 - 可能它不是同一個實例。 – 2014-10-28 18:38:06
