我添加了使用CameraInfo选择相机的代码，因为仅添加Camera.open()无效HTC devices而我将holder中的mCamera.setPreviewDisplay(holder)更改为{{ 1}}这是一个实例变量。
我尝试在一个Activity的mHolder中打开自定义Camera，在logcat输出中我注意到代码在onResume之后进入surfaceChanged因为那是我设置的地方使用surfaceCreated的相机预览尺寸，然后它似乎无法分配内存：Parameters（我的设备上的内存很少 ~2.47GB 可用空间）错了，因为那个。
我收到以下巨大的未知错误，您可以查看我的CameraActivity和我的CameraPreview：

这是我的纵向XML：

现在看起来似乎没有任何东西可以连接到相机，甚至没有连接到默认的相机应用程序。为什么会发生错误，我该如何解决？
这似乎是一个怪异的事情，我关掉手机并重新打开它，它似乎工作正常。另一个原因可能是在 <?xml version="1.0" encoding="utf-8"?>
