I originally built this app to help myself in development, but figured I'd make it available on the Play Store in the hopes it's useful to someone else!
To learn more about the app and what the tools do, check it out on my website: MiromaTech.com/developer-tools
- DateUtils format flags
- Edittext InputType format flags
- color contrast
The DateUtils class provides an easier and better way to format dates and time, but there are a good number of available flags to use, and it's not always clear how they're going to format your chosen datetime. Using this app, you can see in real-time exactly how each flag (and combination of flags) affect a specified datetime.
The EditText has 32 (yup, 32) different InputTypes available to use. While each will essentially have the same functionality across all keyboards, each keyboard may react differently to the InputType. Some display extra keys, some don't. Now you can see how each InputType (and combination of InputTypes) affect your active keyboard.
Everything isn't always #000000 and #FFFFFF.
And when it's not, you need to make sure your text will be readable on your background color. Plug in your foreground (text) and background colors and your contrast ratio will be calculated with those colors. Typically, you're looking for a ratio of at least 4.5:1.
You can enter your color in hex, RGB, CMYK, HSL, HSV, or choose one of Android's material colors.
