  This app was a fun one to design because I wanted to make something that would look different and stand out. Fun to see it get downloaded by so many people all over the world!  Random Number Generator Free, No ads

No, that's not 20k, just 20, but I'm still excited! I released this app last fall as an upgrade version to my Days Until app. It takes a lot longer for paid apps to get downloads than for free apps (obviously), so given that this is one of my paid apps, I'm pretty excited it's reached this milestone!  Days Until Free, No ads Days Until with Widget $0.99, No ads App preview video: 

Another milestone was reached this month! I'll try to do these milestone posts monthly. Volume Button Counter Free, No ads App preview video:

I've been working with Kotlin for a while now, but I haven't started learning to use Jetpack Compose yet. Time to get started learning a new way to make the UI for Andriod apps! I'm excited! The Android team at Google put out a new FREE course as of April 2022: Android Basics with Compose:  https://developer.android.com/courses/android-basics-compose/course

I've decided to start making monthly-ish posts for my app download milestones. I was thinking of making the milestones be whenever the numbers double, but that's too complicated, so I'll post when the downloads hit orders of magnitude of 1, 2 and 5.  Latitude and Longitude Free, No ads App preview video:

Time for some app stats! Time Progress Bars app was released on the Google Play Store in October 2020. Total downloads - 3007 Active downloads - 905 2022 revenue - $31.64 My share of 2022 revenue - $25.31 Total revenue - $54.71 My share of total revenue - $34.23 Revenue is from an in-app purchase that lets users change the color scheme and an in-app donation purchase.

I'm working on an app that shows time progress bars. I wanted the minute progress bar in this app to tick up 1% at a time. I knew that with 60000 milliseconds in a minute, this meant that updating the progress bar every 600 milliseconds should do the trick. My calculations weren't originally precise enough, however, and you can see that before the progress bar would skip 1-3% instead of 1% at a time. This was because I was doing calculations with seconds as an Int. After I switched to doing my division with Longs instead of Integers it worked great!

I receive a lot of reviews of scorekeeper asking for the ability to edit the names of players, which is a feature already available through long-pressing on the player name. Apparently, long-pressing is not something intuitive to try for some people, so they are left without the ability to change the player name. I hope this video preview helps make it easier for users to understand how the app works and how to get to additional features already available to them.

This is my first published app built with Kotlin! :) Features: Use volume buttons to keep score for two teams Can reset to any scores you choose Available in 100 languages Code on GitHub .

1. The first part is setting up your Android phone to get developer options. You can use the Android Studio emulator, but it's much faster to use a physical device. Go to Settings > About phone > tap Build number 7 times. Once you have developer options make sure that USB Debugging is turned on: 2. Next, download Android Studio:  https://developer.android.com/studio/ 3. Start a new project. There are template projects available or you can start with an empty project: 4. Switch to Project view: 5. Java files go in "java" folder, XML files (layout, styles, strings, etc.) go in the "res" file, and sometimes you edit the manifest and the Gradle files: After this, be prepared for downloading time as you might need to update Android Studio.

Thanks to Google and Udacity for the scholarship, and thanks to everyone else I got help from along the way. I've been lucky to have so many people willing to take time to answer my programming/Android questions.

This video shows how I put the finishing touches on my Change Calculator Android app (which will be on Google Play for download soon!). Example of using string.xml, style.xml and color.xml files in an Android app.   Websites from the video: https://www.materialpalette.com/ https://stackoverflow.com/ Link to Change Calculator code: https://github.com/bluepandadev/ChangeCalculator Edit: link to the app on Google Play -  https://play.google.com/store/apps/details?id=com.amandfarrell.www.changecalculator&hl=en

This is a quick tour of how the SQLite database in my simple scorekeeper app is set up. Here's a link to my scorekeeper app code on GitHub if you want to follow along: https://github.com/bluepandadev/Scorekeeper If you want more information on Data Storage and Android, check out this class at Udacity: https://www.udacity.com/course/android-basics-data-storage--ud845 The scorekeeper app is on the play store (in beta still right now): https://play.google.com/store/apps/details?id=com.amandafarrell.www.scorekeeper&hl=en A link to the screen recording software I used:  https://obsproject.com/

This is a 3-minutes video about how to make a simple counter app in Android Studio. I recommend using your own Android phone if you want to try it out, though you can also use the emulators that come with Android Studio if you don't mind waiting patiently while they load.
