  100 days until Christmas! Wow, 2022 is going quick.  Days Until is my latest Android app, available on the Google Play Store. www.AmandaRoos.com/apps

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: 

I've only posted about app milestones for three months now, but this app has already come up twice! My Latitude and Longitude app has the fastest download rate of any app I've made yet. It hit its 5k milestone just two months ago, and now it's at 10k downloads!  Latitude and Longitude Free, 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:

Thanks to the person from Milwaukee, WI who recently bought my donation app! To everyone who has supported my Android apps, whether through donations or other app purchases, thank you! It means a lot to know that the work I'm doing is appreciated! https://play.google.com/store/apps/details?id=com.amandafarrell.www.donationfordeveloper_blue

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

Time for some app stats! Time Progress Bars app was released on the Google Play Store in October 2020.

My Scorekeeper download stats show a consistent spike every Saturday, and big spikes around Christmas and New Year's. I wouldn't have predicted it, but it totally makes sense that people would play more games on weekends and holidays.

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.

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.
