Question

好吧所以我在创建我的动态壁纸时遇到了问题，但我发现这个问题发生在使用股票启动器运行2.3.3的股票连接上。这在我测试过的其他设备上运行得很好：Moto Droid 2.3.3，Nexus S 2.3.4，HTC MyTouch 4G 2.3.3，我只有关于nexus崩溃的报告。

动态壁纸会在壁纸上显示相机的预览。点击设置壁纸后，您将打印下面的堆栈跟踪。您可以看到它设置相机并开始预览，但随后立即调用onDestroy，然后强制关闭，因为之后的错误。整个屏幕都是黑色的。（这是他们选择设置壁纸后，我在小壁纸预览屏幕上没有做任何事情。）

有什么线索发生了什么？没有一个堆栈跟踪进入我的代码。所以我不确定在哪里看。我试图调试它，但它不会触发我的断点中的任何一个，即使是代码中的那些断点似乎正在打击并打印我的日志？

我之前制作了一个用于踢的相机动态壁纸，它适用于API 8到11.注意到N1没有附带库存2.3.3，你使用的是什么ROM？我遇到了自定义ROM的问题，其中Camera硬件XML配置简单并且神秘失败，并且在硬件被强制创建它时被修复。此外：

您没有捕获抛出的RuntimeException，并且您还没有实现Camera.ErrorCallback。您使用的是API 1 Camera.open（）吗？如果是这样，当检测到Gingerbread +时，您应该尝试调用API 9+提供的Camera.open（int）。
