Thanks ~~@josearias210~~ @J0nathan550 (sorry for mistag).

Were you able to get it working on an actual Android device?

Thanks @josearias210.

Were you able to get it working on an actual Android device?

you can run it on device, but there is no ffmpeg implemented to get path to it from resources and using it to convert files

when you are searching for items we need to make a UI thread to update the UI otherwise Java exception

the WebView is broken, when you auth (desktop) it opens the youtube page like you would normally login in browser youtube, it doesn't "auth" you completely.

there is no button for auth in Android version of app for some reason for now

there are a few minor visual bugs for dialogs, that you just add margin to them and they work fine.

There are no permissions added to "export" audio/video of file converted.

This PR is still ongoing, you can push it now and help me with development, or I can try to do everything myself and when I will finish with everything you can merge the pull

@Tyrrrz Progress:

Fixed ffmpeg path fetch
Now you can insert link and find the content you need to download
You can select path and "install" video (installing is not working because of desktop dependency for now)
Created permissions system that will allow us request any permission we like (already asked for needed one to install media)

Where do these directories/files come from?

I removed "unused" arch and forgot to remove them from gitignore

Also, when you are compiling the android project the powershell script at the time of compiling will install all of the binaries for android (like you did with ffmpeg) and will ignore them (not include them to git proj)

Might as well use CliWrap here

Never used your CliWrap. Sorry. If you wish to do it yourself you can later.

Why does this require a new Task?

Will remove it

Looks like this method can just be inlined into a single switch expression

Good enough Android MVP.

Would be good in future:

Add Notifications (to show in background what is downloading)
Add Foreground Service (when you download content it wouldn't exit app if you don't interact with it for long time). (Right now without it, I recommend installing content without going on background with app)
Add ability to open directory where file is located on phone
Add ability to play file on phone
Add Auth System

There are maybe things other things good to be added, but I am not aware of them right now.

Instructions on how to compile Release:

Install MAUI essentials in Visual Studio 2022
Run command: dotnet workload install android (powershell)
Run another command: (powershell)

dotnet tool install -g Redth.Net.Maui.Check
maui-check

Set YoutubeDownloader.Android as Startup Project
Install Android Device Emulator in Visual Studio 2022
Make sure that it is detectable. If for some reason it's not and you are sure that it's installed do this:
- Close Visual Studio 2022
- Go to project structure
- In each different .csproj folder remove bin/obj
- Open Again Visual Studio 2022
- Select Android Project as Startup you should see API level device you need.
Select Release in Build mode
Build without running to debug
Navigate to YoutubeDownloader.Android .csproj folder go to YoutubeDownloader.Android/bin/Release/net9.0-android/
You will see com.tyrrrz.youtubedownloader-Signed.apk <- this is final APK to release.

Some notes on the merge conflicts:

Download-FFmpeg.ps1: use the new file in both Desktop/Android. It should be compatible with both since FFmpegBin provides Android builds.
ProcessEx was moved to ProcessExtensions. If topLevel.Launcher works on all operating systems and not just Android, we should just use that instead of shell execute.
DashboardViewModel needs a closer look.
DownloadSingleSetupViewModel needs a closer look.
MainViewModel should be an easy merge.
YoutubeDownloader.csproj: copy-paste the new csproj over.
