仅仅说“SD卡”通常是个坏主意，因为它在多个设备上是不同的。您最好创建自己的目录来存储文件。

希望您现在已经解决了问题，但我认为您遇到的问题是您正在将相机预览设置为空，并且需要有效的
SurfaceView
作为预览来打开闪光灯（至少在Galaxy Nexus和一些其他三星设备上…）

在布局中添加一个
SurfaceView
，并将其大小指定为1px x x 1px。看起来它至少要有那么大（大小为0会产生不同的错误）。可能需要将
SurfaceView
关闭屏幕（滚动关闭或
RelativeLayout
或其他内容）

  • 若要解决未调用回调的问题，请释放相机并重试。通常可以正常工作
  • 要解决旋转0x80001005的问题，请重新启动应用程序/服务
  • RPC_OMX问题：这似乎与我第一次购买这款手机时的体验非常相似。它安装了4.0.2，偶尔相机会“丢失”——好像我不在那里。只有手机重启在这种情况下才有帮助
    • 您是否遇到异常？如果是，请发布日志。抱歉。我已更新了问题。您如何测试onpicturetaken是否从未被调用？我通过onpicturetaken（字节[]数据，摄像头）中的“System.out.println（“jpegCallback”）”将其打印出来。您正在使用JPEG回调的其余代码在哪里。我看不到您在哪里调用camera.takePicture（），我确实在最后一个块中，将“camera.takePicture（null，rawCallback，jpegCallback）”放在“System.out.println（“6”）和“System.out.println（“7”）之间.这是在点击按钮还是什么？如果我问一些简单的问题，请原谅，但你可能看起来太简单了……你永远不知道lol。这会导致

    这个答案现在已经很老了，但是在安卓系统中，任何硬件接口类型的东西都必须在你将要测试的硬件上进行测试正在使用（我知道…这是我能给出的最没有帮助的建议）并用新的硬件和固件版本进行测试…有一些规范，但制造商真的可以做任何他们想做的事情
