Update to Keep Calm

I updated Keep Calm on Google Play today to version 2.2.5. This new update fixes a couple of bugs and makes poster generation a lot more efficient which should, in theory, mean that the app is a lot less likely to crash – an error reported due to a memory error.

The reason that the app had been crashing for some users (especially those with older phones with less RAM and older versions of Android) was because the background of the poster was being regenerated every time something was changed on the poster. This was a necessary because Keep Calm Pro allows for a greater variety in the backgrounds (solid color, linear gradient, radial gradient and an image) however was completely unnecessary for Keep Calm and therefore lead to an unnecessary Bitmap object hogging up memory.

The two apps share the same class to generate the poster (its called Dunkirk and the majority of variables, functions and classes in the app get their namesake from various WWII battles to keep me entertained whilst coding) so an extra function has been added to this that generates higher quality posters. I also adjusted the resolution the preview as rendered at – by default it is 600 by 900 (this is the export resolution) however if the screen resolution is lower than that it will be rendered at the lower resolution.

Hopefully this update has fixed any bugs that were in Keep Calm which is now within in three/four days of 50,000 downloads :).

Updates to Keep Calm and Keep Calm Pro

I have made a few improvements to Keep Calm and Keep Calm Pro for Android. The key improvement that has been made is that the app is now fully multi-threaded which means it is a lot less likely to crash (I am ashamed to say that, yes, everything had been running in the UI thread before – oops).

Both apps now include PT Sans as the default font and Keep Calm Pro now allows you to choose between Open Sans, Open Sans Light (which used to be the default), PT Sans and the standard system font. I chose PT Sans because it matches the original font quite well. A less major modification that has been made to both apps is the change of the background color :).

In response to comments I have also added a new option to Keep Calm that allows you to use the old designer. This feature has not been added to Keep Calm Pro as it would have made it far too complex and I believe the menu/sub-menu system that it currently uses is far more efficient.

User guide for Keep Calm 1.x

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!

Your Country Needs You v1.1


I’ve done an update for Your Country Needs You which brings it to version 1.1 on the Android Market. It now allows you to modify the background color which seemed to be a logical progression and the only reason that it wasn’t in the original version was because I completely forgot to add it in. In a future version I do intend that it will be possible for you to modify Lord Kitchener’s face however he is sticking around for the time being.

Keep Calm v1.2.2

This isn’t really a major update to Keep Calm for Android however it finally fixes the issue of posters not saving properly. It turns out that they were saving all along, however the Gallery app doesn’t refresh the picture list straight away. I’ve written up an explanation here.

Free Android app: Your Country Needs You

As a natural follow up to my Keep Calm and Carry On app it made sense to develop another similar app based on another famous British wartime poster. This new app allows you to modify the text of the poster however you will soon be able to change Lord Kitchener’s face to your own face and also change the background color (this update will probably ship in the next week).

The app also fixes the saving error in the Keep Calm app* – it turns out that your posters were saving but not always appearing in the gallery. This was a technical error in that the gallery app doesn’t check for new images when it loads and so adding one extra line of code in my app automatically refreshes the gallery. As well as saving you are also able t0 share, set as wallpaper and choose from three fonts – Alfa Slab One, Enriqueta, PT Sans.

*Don’t worry, I’ll be updating Keep Calm so you can save your pictures properly in that too.
