Java 调用意图时出现摄像头错误。安卓

我不知道为什么我会出错

摄像机误差 无法连接到相机

这是我的意图代码（是的，我在清单文件中有权限）

final File root=新文件（Environment.getExternalStorageDirectory（）+File.separator+“MyDir”+File.separator）；
root.mkdirs（）；
最后一个字符串fname=getUniqueImageFilename（）；
最终文件sdImageMainDirectory=新文件（根，fname）；
outputFileUri=Uri.fromFile（sdImageMainDirectory）；
//照相机。
最终列表cameraIntents=newarraylist（）；
最终意图捕获意图=新意图（android.provider.MediaStore.ACTION\u IMAGE\u CAPTURE）；
最终PackageManager PackageManager=getActivity（）.getPackageManager（）；
最终列表listCam=packageManager.QueryInputActivities（captureIntent，0）；
用于（ResolveInfo res:listCam）{
最后一个字符串packageName=res.activityInfo.packageName；
最终意图=新意图（captureIntent）；
setComponent（新组件名（res.activityInfo.packageName，res.activityInfo.name））；
intent.setPackage（packageName）；
intent.putExtra（MediaStore.EXTRA\u输出，outputFileUri）；
添加（意图）；
}
最终意图选择器CameraIntent=Intent.createChooser（captureIntent，“使用照相机”）；
startActivityForResult（选择Camerainent，您的\u选择\u图片\u请求\u代码）；

以下是logcat错误：

如果摄像头应用程序崩溃，它会锁定摄像头硬件，防止在设备重新启动之前再次使用。因此，如果您遇到“无法打开摄像头”和类似的消息，请尝试重新启动设备，看看问题是否解决。

尝试重新启动设备。无论你遇到什么，都是使用摄像头应用程序，可能与你的代码无关。谢谢你这么做了。。。那是怎么发生的呢？
