I copied the code from the answer here and I still am getting a RuntimeException: setParameters failed error on my nexus one. My manifest file has camera and wake_lock permissions. This works on the emulator, and on the droid I don't get the error but it does have a rotation problem.

推荐答案

您很可能请求的预览尺寸无效.如果您检查 adb logcat 的结果，您可能会看到如下内容:

You're most likely requsting an invalid preview size. If you check the results of adb logcat you'll probably see something like this:

E/QualcommCameraHardware(22732): Invalid preview size requested: 480x724

解决方案是请求与您想要的最接近的可用预览尺寸；您可以通过在 getSupportedPreviewSizes 来获取可用预览尺寸的列表Camera 返回的 "noreferrer">Camera.Parameters 对象.getParameters.

The solution is to request the closest available preview size to the one you'd like; you can get a list of available preview sizes by calling getSupportedPreviewSizes in the Camera.Parameters object returned by Camera.getParameters.
