Android devices

• Moto G Power 2021 phone (2 of them)
• Moto E4+ phone (2 of them)
• Google Nexus phone (I use it as an alarm clock)
• Lenovo 8" Tab M8 TB-8505F (Hinge Health) Android 9 "Pie" Cortex-A53-2Ghz 2/32GB
• Samsung Galaxy Tab A 8" SM-T387T s/n R52M50MZR8V Android 10 Cortex-A53 4core 1.4GHZ 2/32GB

10" tablet from Patrice, maybe an ASUS? She was going to recycle it. Works perfectly. Something is very wrong with Western Civilization.

G Power phones are too big (I think) and run Android. I'd rather not support Google. I think our next phones will be feature phones. It should be interesting trying to survive without some of the apps I rely on today, such as Authy.

The E4+ phones were fine, but the provider started requiring VoLTE (VOIP over LTE) and is shutting down CDMA to move to 5G. We got E4+ phones because they supported CDMA and that worked better in Astoria.

The Google Nexus phone was fine but supports only GSM and HSPA+ so it did not work well in Astoria. I had CyanogenMod on it for several years.

Android development

Android Studio

Go

Go language or golang if you prefer

Writing services for Android in Go https://dennisforbes.ca/index.php/2014/03/19/go-golang-and-android/ I think the idea here is that you can replace C native code with GO. See also https://www.reddit.com/r/golang/comments/2kv0s1/go_14_on_android/

So it would be useful currently for example to talk to hardware.

Or maybe it could implement a tile downloader, that is, the network/concurrent part.

Settings

That ellipsis thing (three vertical dots) is called "Settings".

I want my app to show a menu when the user clicks on it, so I have to add a PreferencesActivity. I also need to associate the resources with it to define what shows up.
