QUESTION
This code receives information from an acquaintance you want to register in editText, and then clicks finButton to save the information you receive as a file called friendlist.txt. However, the Toast message is outputted from the try-catch statement that is currently performed when finButton is pressed. Also, the checkpermission does not work, which is wrapped in a try~catch statement, but does not have output on the logcat.
And manifest.
uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"
uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
is written.
Please let me know the solution. And this content is written with a translator, so the sentence can be strange.
when you press finButton, the logcat is shown below.
The code corresponding to the 116th line is this.
...FileOutputStream outstream = openFileOutput("friendList.txt", Activity.MODE_WORLD_WRITEABLE);

In CameraX Analysis, setTargetResolution(new Size(2560, 800), but in Analyzer imageProxy.getImage.getWidth=1280 and getHeight=400, and YUVToByte(imageProxy.getImage).length()=768000。In Camera, parameter.setPreviewSize(2560, 800) then byte[].length in onPreviewFrame is 3072000(equales 768000*(2560/1280)*(800/400))。How can I make CameraX Analyzer imageProxy.getImage.getWidth and getHeight = 2560 and 800, and YUVToByte(ImageProxy.getImage).length()=3072000? In CameraX onPreviewFrame(), res always = null, in Camera onPreviewFrame(), res can get currect value, what's the different between CameraX and Camera? And what should I do in CameraX?

Answered 2021-Jun-13 at 01:15With regards to the image analysis resolution, the documentation of ImageAnalysis.Builder.setTargetResolution()
states that:
The maximum available resolution that could be selected for an ImageAnalysis is limited to be under 1080p.
So setting a size of 2560x800 won't work as you expect. In return CameraX seems to be selecting the maximum ImageAnalysis
resolution that has the same aspect ratio you requested (2560/800 = 1280/400).

getApplicationInfo Throws PackageManager.NameNotFoundException if a package with the given name cannot be found on the system.
In your case you are looking for com.mi.android.globalfileexplorer

QUESTION
I have looked for this everywhere but cannot understand what to do.
I understand that UWP apps need their dependencies installed, but do they also need .Net/.Net Core installed on the client machine?
What I am doing:
Using another UWP app and the PackageManager
class, I am making my own installer. (UWP installs UWP)
So I know I will have to install the dependencies (appx
files) too, but do I also have to make sure that .Net/.Net Core is installed? Thanks!
ANSWER
Answered 2021-Jun-03 at 14:45but do they also need .Net/.Net Core installed on the client machine?
No. A UWP app targets a natively implemented SDK version that doesn't have any dependency on .NET Core.
The C# language projection is indeed based on .NET but the CoreCLR (.NET Core runtime) is not used at runtime so you don't have to install any addtional .NET stuff on the client machines where your UWP app is run.

PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
