I believe this has already been discussed in Discord and can't merge it without authorization. https://discord.com/channels/629952586895851530/817392867995680768/1144027007756292186

Hello,
Understood. Please wait a little longer — MilosKozak is likely still evaluating it. If it turns out to be unsuitable in the end, I will close this PR.

[psonnera]

Excellent, I keep it open. Thanks.

[MilosKozak]

can you include html file to this PR? @Angus-repo

[MilosKozak]

the link is wrong now

[Angus-repo]

Hello,
I have added aaps-ci-preparation.html to the PR. It can be downloaded from the wiki. Please review.
BuildingAaps.html

[psonnera]

@Angus-repo great doc and videos. Couple of gaps: most users don't have a fork of the main repo, I'll add instructions on how to fork and update. Links will have to be updated as it's not clear which URL you need to download the html (for now your repo). I will also try to get the jks java generator into readthedocs (did you try?).

[Angus-repo]

Thank you, psonnera, for the reminder.
The method for obtaining the GitHub repository has changed, and indeed it should be explained.

I will first add the prerequisites, and then you can check if anything else needs to be supplemented.
BuildingAaps.html

Once it is officially merged into the main repository (master branch), it will only be necessary to fork from the main repo.

Currently, the preview aaps-ci (readthedocs) already includes the download link for aaps-ci-preparation.html, which contains the JKS generation. This JKS is compatible with the information required for building the APK, so there’s no need to include a separate Java JKS anymore.

@Angus-repo please have a look at the test page https://androidaps.readthedocs.io/en/latest/SettingUpAaps/BrowserBuild.html (not linked to the menu) and continue PRs on it. I copied the files and contents from your PR and added some steps for non-techs. Free to chat on Discord, Facebook or here. Thank you.

[psonnera]

@Angus-repo and now I see you did more in the meantime. Sorry for the interference...

[Angus-repo]

@psonnera , thank you. I will close this PR, and for future modifications to BrowserBuild, I will submit a separate PR. Thanks.
