问题 In Android Q the MediaStore.Files.FileColumns.DATA field has been deprecated, and may be null or apps may not have the rights to read it, therefore is there a way to rename the filename section (not the path) of a file using only its media content Uri? Until now the DATA field could be used to find the real path of a file from a known Uri, but since it has been deprecated then the idea is not to even try to find or resolve the real file path, and use only its content Uri. Consider that the

问题 I'm using Retrofit to manage my requests and want to make some tests to check de request size using or not using gzip. By default does OkHttp performs gzip compression to requests or it must be implemented with an interceptor? I've added @Headers({ "Accept-Encoding: gzip, deflate", "Content-Encoding: gzip" }) or: @Headers({ "Content-Type: application/json;charset=utf-8", "Accept: application/json" }) to my requests and did not see any change on the request length. 回答1: OkHttp will do

问题 I want to add icon to left of DropDownButton but can't find a way to do so. What I want to achieve is like this: I have tried following code but it places icon to right where I don't want it and it also overrides arrow icon: `@override Widget build(BuildContext context) { return Scaffold( body: Container( margin: EdgeInsets.only(top: 64.0, left: 16.0, right: 16.0), color: Colors.white, child: DropdownButton( icon: Icon( Icons.person, color: Colors.redAccent, size: 20.09, ), isExpanded: true,

问题 I've worked on this for days now. I have an OpenCV/JavaCameraView-based project I am trying to integrate with an Android android.hardware.camera2.CaptureRequest object I use to control the camera's sensitivity to light. The CameraBridgeViewBase.CvCameraViewListener2/JavaCameraView project works (I can see an image on the screen), and the CaptureRequest project works (see this, too), but combining the two technologies in a single project has proved a big problem. Has anyone gotten these two
