Android on Windows

2023-05-09T15:06:03Z

Slow Android emulators to test Android programs may be a thing of the past on my current Windows system. I downloaded and installed Windows Subsystem for Android. It's a convenient way to test out apps you've created without having to resort to installing VirtualBox and Android x86 or using other alternatives such as Qemu or some of the very slow Android app emulators.

QEMU Cheat Sheet

2021-06-29T14:58:13Z

I just got used to VirtualBox and ended up having to switch to QEMU. VirtualBox seems to run better than QEMU. I tried to load several operating systems in QEMU that ran fine under VirtualBox and they failed. Decided to try a Debian netinst because that works well with most machines. Then I had to figure out all over again how to get files between the host and guest systems. It's harder to find documentation on what you're looking for with QEMU as compared to VirtualBox.

Open Source Android Development

2019-09-05T19:57:24Z

Was recently commenting on a forum about how few Open Source alternatives there are for Android devices. The Free Software Foundation even had a wiki page about how development for mobile devices was a priority. However, when I wrote to them on the subject, they didn't bother to acknowledge or answer my e-mail (until just recently, two years later).

GUI library design

2019-02-20T15:00:28Z

Some of the C graphics libraries are great, but I've yet to find a simple GUI that makes it easy to port some older BASIC programs that I want to be able to keep working with. I've created several iterations of my own GUI library, but have never been satisfied with the results. That's the main reason I keep investigating cross-platform GUIs, to see if someone's found a better way to do it. Of the various designs, the ideas behind the immediate mode GUIs seem the most useful for the type of programs I'm targeting. However, I can't seem to find one GUI library that provides a simple way to do what I want. So, I've decided to revisit my old GUI library designs but eliminate some of the framework constraints and some of the object oriented elements. Instead, I'm looking at a more procedural approach that uses concepts from immediate mode GUIs.

C/C++ and Android

2018-02-04T16:35:23Z

I've been searching technical books and articles to find out more about writing programs for Android using the native development toolkit (NDK) and C/C++. Finding relevant information is extremely difficult. Most sources just say to use Android Studio (or for older articles, use Eclipse) and do not go into any details as to how things work beyond the IDE or wrapper script. It's extremely difficult to find documentation that explains what's going on underneath.
