Last week I talked about using SMS to activate your application which is a pretty powerful way to verify a user account. I left a couple of things out though. One of those things is the ability to grab the incoming SMS automatically. This is only possible on Android but it's pretty cool for the users as it saves on the pain of typing the activation text.Read More
Continuing the trend I revisited the old crash protection video in the "how do I" section and updated it with current information and details. The old video still featured an old flag that should be avoided...
The new video is relatively short and simple as the feature isn't very complex, I hope to produce several more of these and bolster the video section further.
I already have half a post on text components but I've put that on hold for now as I've been working on the on-top side menu to supersede the existing side menu bar implementation. I've made some fixes for it over the week, I wanted to make it the default for Codename One apps but it still isn't "perfect". We will make it the default within the next couple of weeks so please test it after this weeks update and let us know ASAP if you spot any issues!Read More
A very common question we get from developers is "how do I get the devices phone number". The answer is "you can't really and you shouldn't". To clarify, this is possible on Android but would require a scary set of permissions. It's blocked on iOS completely though so you'd need a different solution anyway...
If you look at apps like Uber, whatsapp etc. they all use SMS activation. They just ask you to type your number and activate your phone via SMS. Usually this SMS is sent from the server side but for simplicity lets discuss how this can be done entirely from your app.
I redid the include source tutorial which was really old by now and included some outdated "facts" while missing key information. Include source allows us to get the native OS project source code on build, this allows us to debug and profile on the devices.Read More
I haven't blogged as much in the past month and as a result I have a big pile of updates from all over. This is going to be a big list so I'll start with a few pull requests that were submitted by Diamond and Durank. If you see something broken or something that could be better in Codename One just fix it like they did!Read More
I have blogged, in the past, about UI design in Codename One. In one tutorial, I walk through the process of converting a PSD file into a mobile app. Unfortunately, upon re-reading that tutorial, I realize that I completely skipped one of the most important steps. I essentially began with "let's make our app look just like the design", but I didn't describe what it meant to look "just like the design". In this blog post, I'd like to unpack what "just like the design" means to me, in the context of mobile app development.Read More
The summer is finally coming to an end but we might not get to full speed before mid September. Thankfully this didn't impact Steve who did some pretty great things this August including a lot of GUI builder fixes/enhancements that we'll cover with the next plugin update. But what we will have this weekend is pretty spectacular. As a short PSA: we're pushing out the weekend release right now because I'll be traveling tomorrow. So all this should be available today.Read More
I've been working on the new pixel perfect post which I would like to focus around the text components, in order to do that I needed an underline border type. Historically this is something we shrugged off and pointed people at the 9-piece border. That was the wrong answer and it partially related to the way rendering used to work in Codename One and partially related to our reluctance in changing the resource file format.Read More
