newRPL for Android - early release for testers

[Eric Rechlin]

The hardest thing about Android development when dealing with a bitmapped UI is making sure things scale properly with all the different aspect ratios, resolutions, and DPI settings that various devices can have. Even a single phone model can have a bunch of variations (for example, my S7 has three different screen resolutions you can run at, and within each resolution you can three different DPI/scaling factors too, and I am running at the highest resolution and the smallest scaling factor). That's why vector/scalable UIs are preferred instead, but that obviously would require a lot of extra development effort. The Droid48 emulator does a pretty good job of handling this, so maybe looking at its code could be useful.

With the emulator in Android Studio you can set different OS versions and different screen sizes and resolutions to see how it responds, which helps, but of course it's best to find people with different physical devices too.
