Upgrading Old Flutter Apps
Posted Saturday, December 28, 2024 at 11:31 AM in Flutter, Mobile DevelopmentI recently purchased a Google Pixel 9 phone and migrated all of my stuff to it. The transfer process is very thorough and gets all of my app store apps plus existing data. Unfortunately, Google's migration process doesn't migrate applications I deployed to the device via side-loading (installing them directly on the device using Android Studio). These are Flutter apps I wrote for myself and I only update them when I get a new device. This post explains my process for upgrading the apps for new phones.
Google Identity Confirmation Failure
Posted Monday, November 25, 2024 at 07:54 AM in Miscellaneous, Mobile DevelopmentGoogle recently started asking for ID verification for Play Store developers. The time came for me to submit mine and I dutifully submitted both a scan of my passport as well as a scan of my driver's license (both sides). Google, of course, repeatedly failed the verification process without telling me anything about what was wrong with my submission.
Repeating Countdown Timer in Flutter
Posted Thursday, June 20, 2024 at 05:07 PM in Flutter, Mobile DevelopmentA while back, while anticipating a particular event (my retirement), I decided to create an app that allowed me track the number of days until the event.

Platform-Specific Links in Ionic
Posted May 14, 2020 in Mobile DevelopmentWhen I submitted my mobile app to Apple for inclusion in the App Store, they rejected my app since it used Android screen shots in the app's tutorial (using Ionic Slides).

Introducing the Time Slicer App
Posted November 27, 2019 in Mobile DevelopmentI was watching the evening news one day and started thinking about how much of the show was allocated to different topic categories (local news, national news, sports, etc.); I was especially curious about what the ratio was of news vs. commercials (there seemed to be a lot of car commercials). I decided to build an app that enabled me to capture (measure) the amount of time allocated across multiple categories. I thought perhaps that others would like a similar app, so I decided to publish it as my first app store app.
