Control Text Size on Android Bottom Navigation View

It seems as though my obsession with the Android Bottom Navigation View aka Bottom Tabs will never end! This time I got a question about controlling the size of the text when the user taps on a tab. The default behavior is to zoom in on the text: Inside of your Android project's Resources/values folder create a new file called dimens.xml if it doesn't exist. Then add the following XML to override the size of the text when it is active and not active: <resources xmlns:tools="http://schem…

From there a bunch of companies attempted to fix the problem by using custom built solutions on top of Virtual Box or Hyper-V. Google has done a lot of work in the last few years to improve the Android emulators with Quick Boot, more customization…

PSA: Android Pie Reports "9" for Release Version instead of "9.0"

Let's break down a version number together, or as standard documentation says, it "represents the version number of an assembly, operating system, or the common language runtime" and that "the format of the version number is as follows (optional components are shown in square brackets ([ and ]): major.minor[.build[.revision]] In the world of .NET this has always been a staple of how we version anything. Major and Minor are required and the other bits are optional, which makes it…
