Nexus One設備上的相機和動態壁紙出現問題

Question

好吧，我遇到了我創建的動態壁紙存在問題，但我只發現此問題發生在股票相連一個運行中2.3.3使用股票發射器。這對我測試過的其他設備非常有用：Moto Droid 2.3.3，Nexus S 2.3.4，HTC MyTouch 4G 2.3.3，並且我只有關於nexus的崩潰報告。

動態壁紙在您的壁紙上顯示您的相機預覽。點擊設置牆紙後，您將打印下面的堆棧軌跡。你可以看到它設置了相機並開始預覽，但是之後立即調用onDestroy，然後由於之後的錯誤強制關閉。整個屏幕都是黑色的。 （這是他們選擇設置壁紙之後，我沒有在小壁紙預覽屏幕上做任何事情）。

任何線索發生了什麼？沒有一個堆棧跟蹤會嵌入我的代碼中。所以我不確定去哪裏看。我試圖調試它，但它不會觸發我的斷點中的一個，即使是代碼中它似乎正在打印和打印我的日誌？

我，你使用的是什麼ROM製作的，它通過11注意到N1不與股票2.3.3船舶工程對API 8之前踢相機動態壁紙？我遇到過自定義ROM的問題，其中相機硬件XML配置簡單且神祕失敗，並在硬件被迫重新創建時被修復。此外：

你沒有捕獲拋出的RuntimeException，並且你還沒有實現Camera.ErrorCallback。你使用API​​ 1 Camera.open（）嗎？如果是這樣，當檢測到Gingerbread +時，應該嘗試調用API 9+提供的Camera.open（int）。
