它以前曾经工作过，但是问题似乎出在我使用Android 7(API 24)上.

It was working before but it seem the problem is since I use Android 7 (API 24).

这是我的代码:

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                imageUri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(), "fname_" +
                        String.valueOf(System.currentTimeMillis()) + ".jpg"));
                intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
                startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);

推荐答案

如果您的targetSdkVersion为24或更高，我们必须使用FileProvider授予对特定文件或文件夹进行访问的类可用于其他应用.我们创建自己的类继承FileProvider，以确保我们的FileProvider不冲突使用在导入的依赖项中声明的FileProviders进行描述在这里.

If your targetSdkVersion is 24 or higher, we have to use FileProvider class to give access to the particular file or folder to make them accessible for other apps. We create our own class inheriting FileProvider in order to make sure our FileProvider doesn't conflict with FileProviders declared in imported dependencies as described here.

从Android 7开始，我们不使用file:scheme作为uri来表示意图，因此您必须使用FileProvider.

Since Android 7, we don't use file: scheme as uri for intent, you have to use FileProvider.
