Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      So what barrier to entry is there to downloading https://dl.google.com/android/repository/sdk-tools-linux-3859397.zip … from https://developer.android.com/studio/index.html … and using sdkmanager to update / install whatever you need?

      That's a start and probably ok for lots of users (but buried and hard to find and not documented). They don't even have a link to the source anywhere I can find though.

      Looks like big distros (e.g. Debian) might have it packaged tho, in which case you get most of the benefits of source (trusted reproducible build, compat with whatever arch you're running not just x86_64, ...).

      Debian has packages but it's a bad idea to use those. It's important to use the up-to-date tools and it really doesn't need to be installed system-wide. Can also decide to install the IDE later and it knows how to use an existing minimal SDK directory for the tools.

      Well where do you get the sources to build the SDK? This is all so awful and undocumented.

      Not sure why you're talking about building it now. A hello world tutorial doesn't really start with building glibc, binutils and GCC.

      If you really want to use Debian packages, you can use them, but then you're deciding to do things in a weird way where you're using frozen Debian versions of the packages installed system-wide. If you were writing Python code, would you use their versions of libraries?

      I'd get the versions of the libraries I wanted but install all the *tools* from packages.

      A basic project with an activity saying hello world is 20 lines of configuration and 5 lines of code. Don't need to install an IDE and libraries are separate from tools. Was trying to help but not seeing the point when you just want to be hostile and spread uninformed FUD.

      Is there any "hello world" like that I can look at that's not using some awful IDE tree layout, just the minimal number of lines/files needed to actually make something that can be built and run?

          https://github.com/copperhead/Hello/tree/flat … shows how to flatten it into a more traditional gradle project, like Signal. The gradle wrapper commit is optional. It makes it easier for people to build. It uses the support library so it's not minimal, but nearly everything should use the support lib.

          Could delete colors.xml and remove the references to it for the standard theme, and it could use a baseline layout like LinearLayout to avoid that extra support library dependency. Probably do want to use appcompat for support legacy Android sanely via static linking + shims.

          A minimal app would use Activity instead of AppCompatActivity but then it doesn't have the support library providing newer APIs for older targets and automatically working around bugs in the older OS. If target is API 23+ or so, can do w/o it and have a tiny apk but prob want it.

          They're starting to deprecate as much as possible in the base OS with Android P (9.0) to only have it implemented in the support libraries. AppCompat is still totally optional but even if an app starts as API 23+ today and doesn't need it, it probably will want it later on.

          Could also delete the repositories for downloading dependencies with gradle.

          https://developer.android.com/studio/write/java8-support.html … and https://developer.android.com/studio/publish/app-signing.html#gradle-sign … are other baseline things that are usually wanted. Also, project structure with Bazel or an alternative would probably look exactly the same as this flat approach to gradle. The nesting is super over-engineered.

          Find it bad enough that Java projects nest directories based on namespaces and reverse of the domain is the standard baseline namespace. Can avoid that by adding a prefix via gradle but it'd be kinda weird.
