Programming and general geekiness.

I first released Keep Calm for Android over a month ago and it remains the best Keep Calm and Carry On app available on Google Play with over 30,000 downloads and over 200 ratings. Recently I’ve had a number of comments suggesting that the ‘app freezes on the loading screen’ and other basic problems so I thought that I would write up a quick guide for basic usage. Please note that I am launching an awesome update to the app within the next week which gives it a completely new UI with loads of new options.

1) The home screen

This home screen (its not a loading screen!) is pretty simple and you can just press ‘Design’ to get going. There isn’t much interesting stuff on the ‘About’ screen.

2) The design screen

This screen is also pretty easy to use. When typing the text you do not have to have it on separate lines and if you do have it all on one line it gets split by word. Capitalization isn’t important because this happens automatically, staying true with the original poster. If you don’t type in anything the default text of  ‘KEEP CALM AND CARRY ON’ is used. The icon button probably doesn’t need any explaining – just tap it to be presented with a choice of 50 icons and then tap the one that you want to use. Tap the color button to pick a new color.

The color system used by version 1.x isn’t great, sadly (although it uses a color wheel in version 2). The sliders use the RGB color system where each color is represented by its red content from 0 to 255, green content from 0 to 255 and blue content from 0 to 255. To put it in perspective the color black is R0, G0 and B0 (because it doesn’t have any red, green or blue) and white is 255, 255, 255. The sliders therefore give you a choice of 16.7 million colors. You can the tap ‘Use Color’ once you are happy. Unfortunately version 1.x doesn’t allow you to change the text color so I have to recommend that you use darker colors.

3) The final poster

Once you’ve tapped ‘Design’ you’ll be able to see a preview of your final poster. The poster is rendered at 600 pixels wide by 900 pixels high. You can either tap the poster itself or press the Menu button on your phone to display the menu. As of version 1.2.2 tapping Save will save the image to the SD card and then display it in the Gallery app. In earlier versions it seemed that a user had to reboot their phone or wait a significant amount of time for the image to appear in the Gallery however a bug with Android stops the Gallery app refreshing by itself so I added one line of code to force it to refresh. Sharing will display a menu of different options for saving, dependent on which social networks’ apps you already have installed (so you’ll need the Twitter app to share on Twitter, the Facebook app to post on Facebook, etc).

Setting as wallpaper works exactly like saving except that a new image has to be generated because Android handles wallpapers in peculiar ways and requires a landscape image so it occasionally takes a while to set the wallpaper on older devices, but on new devices it is pretty much instant.

Hopefully this guide will have helped some of the users that are having issues with version 1.x. If you have an older version than the most recent 1.2.2 update I highly recommend that you update although in a week there will be an awesome new update that will give loads of new features, such watch this space!
