installers

APK with V1 signature already at Google Play and installed on devices lover Android 11. Now we want to support Android 11 devices, but it requires V2 signature. Enabling the check-boxes of both V1 and V2 we get APK, but it refuses to be installed with INSTALL_FAILED_UPDATE_INCOMPATIBLE.

How possible to build APK which will be supported by all devices?

I checked signature certificates of built APKs. They are Release certificates.

Some probably useful logs snippet:

I wrote a WPF program using .NET 5, packed it into the MSIX bundle (Release, x86 and x64) as a framework-dependent package. Everything seems fine, but there is one very annoying thing: on the first run the app says ".NET runtime is missing, would you like to install it?”. If you click yes, the download page opens, where the user has to select the needed runtime, download, and install it. Not the best user experience, I'm thinking about how to improve it.

Is there an option to add .net 5 runtimes (x86 or x64 depending on the user system, or maybe both) as a dependency so it installed automatically?

I know I can define dependencies, but how can I find the right name for the needed dependency?

Also, I know it's possible to define custom install action but I haven't tried it yet, because I want to find a simpler solution. Looks like for that option I'll have to create a small app or script that will check if the needed runtime exists and if not - check the platform and ask the user to install the specific version of the runtime. Not the best user experience too.

Of course, I still have an option to go with self-contained, but I don't want to distribute so many megabytes of .net every time, especially given the fact that I expect frequent updates.

I require the use of F# 4.5 running on the .NET Framework (not .NET Core). I would like this environment running in a docker container as it'll run periodically on our Jenkins build server. I thought that I could use the existing .NET Framework SDK Image but it only has F# for .NET Core/.NET 5.

So I attempted to install F# into the running container (should that work, I would add it to the image itself) but I am not having any luck. Here was my attempt...

1. Create a project folder

2. Download vs_BuildTools.exe to project

3. Create a Dockerfile using the .NET Framework SDK 4.8 image

We are looking for an approach to extract our application JARs and resources from an EXE installer built with install4j. We are trying to automate installers testing though without actual installation - we want to run our application main JAR unpacked from an installer.

With help of PE file format parser https://github.com/kichik/pecoff4j I've found the major part of content is placed in some kind of preamble of an image. The same entry with the same size is shown when I opened the installer in 7-Zip: But the format of the entry is unknown to 7-Zip and I can't to go deeper. When I opened the entry in a hex editor I found some of the application resources content, classes names, etc.

The question is - what is a format of the entry and how can I parse it?

P.S.: It seems there should be no issues with DMG for Apple and SH for Linux - as they are regular archives and I hope I can read them in my Java code.

I'm trying to use tox to automate pytest testing of my project on Python 3.7 and 3.8 but am struggling with how to best set this up. What's the easiest way to get multiple Python versions installed on my Windows 10 machine in order to use them with tox?

If I just manually install them using the official installers how do I set up my environment variables? Because each installation contains python.exe, so if I install two versions and add both their paths C:\Program Files\Python37\ and C:\Program Files\Python38\ to my Path environment variable this won't differentiate them... python will just refer to the first one listed. So do I need to go and manually rename the python.exe files to names like python37.exe and python38.exe? This all seems very manual and clunky but I can't find any easier way or tutorial about this step.

The tox documentation just gives a solution using conda, but I'm not using conda and don't want to switch to it just to use tox.

If Python version paths and aliases are set up manually, then if someone clones my project to work on a PR and wants to run tests locally, tox would not work correctly if their Python install locations are different or they're on a different OS. Is there some standard way to define and set this all up so things are easy and consistent across machines?

If all this is unavoidable, what is an alternative to tox for consistently testing projects across multiple Python versions that can work on any machine or CI/CD pipeline?

I am trying to set up one of the installers from the NSIS tutorials. The installer simply writes a text file to the desktop that says "Hello world!". The installer script reads as follows:
