【问题描述】：
我不知道为什么会出错。
相机错误 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 = new File(Environment.getExternalStorageDirectory() + File.separator + "MyDir" + File.separator);
root.mkdirs();
final String fname = getUniqueImageFilename();
final File sdImageMainDirectory = new File(root, fname);
outputFileUri = Uri.fromFile(sdImageMainDirectory);
// Camera.
final List<Intent> cameraIntents = new ArrayList<Intent>();
final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
final PackageManager packageManager = getActivity().getPackageManager();
final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
for (ResolveInfo res : listCam) {
final String packageName = res.activityInfo.packageName;
final Intent intent = new Intent(captureIntent);
intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
intent.setPackage(packageName);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
cameraIntents.add(intent);
}
final Intent chooserCameraIntent = Intent.createChooser(captureIntent, "Use Camera");
startActivityForResult(chooserCameraIntent, YOUR_SELECT_PICTURE_REQUEST_CODE);
这里是 logcat 错误：

尝试重启您的设备。无论您遇到什么都与相机应用程序有关，可能与您的代码无关。

谢谢你这样做了......但这是怎么发生的？
