我在Archos 32 Android设备上收到此错误。我发现了这篇文章：Droid's mediaserver dies on camera.takePicture()
但是对于预览之外的“缺失部分”，它并不是非常具体。
我的代码在模拟器和至少一个其他机器人设备上运行。是否只是与archos不兼容或者我仍然会遗漏某些东西？
Archos有一个工作相机程序，所以我知道可以有一个拍照的应用程序，但我开始认为与sdk有一些不兼容。我在哪里可以下载完整的工作相机eclipse项目？我能找到的只是代码片段。
这是调试日志：

我还有一个Archos32展示了与您相同的问题。你有没有找到问题的答案？我已经检查了你的代码，我的Archos32的mediaserver也在试图拍照时死亡。
我已经更新了你的代码，并且让它在媒体服务器拍照时不会死亡。我基本上以下列方式更新了Preview.java：
public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) {
// Now that the size is known, set up the camera parameters and begin
// the preview.
Camera.Parameters parameters = camera.getParameters();
List<Size> previewSizes = parameters.getSupportedPreviewSizes();
Size optimalPreviewSize = previewSizes.get(0);
// parameters.setPreviewSize(w, h); // seems to crash if this code is enabled
parameters.setPreviewFormat(ImageFormat.JPEG);
parameters.setPreviewSize(optimalPreviewSize.width, optimalPreviewSize.height);
camera.setParameters(parameters);
camera.startPreview();
}
这很糟糕＆amp;脏，因为我没有做任何特别的事情来确定用于相机预览的预览尺寸 - 我只是抓住第一个找到的 - 但我所做的更改的结果是媒体服务器不再崩溃onShutter （），现在也调用了rawCallback（）和jpegCallback（）。
如果需要，您可以从Google's CameraPreview API Demo获取getOptimalPreview方法，以获得拍照时使用的“最佳”预览尺寸。
让我知道这是否适合你 - 我一直在与我的爱可视公司争夺数小时试图让相机实现而不会崩溃，并且最终开始取得一些进展。
