Proguard is one of the most disliked aspects of Android programming. Developers attack it left and right because there are so many nuances to it. That’s a huge mistake, proguard is one of the most important tools in our development toolchain. It makes our apps slightly more secure, much smaller and even slightly faster. Codename … TIP: Obfuscation Mapping File

Some of our older components were developed years ago. As Android and iOS slowly converged their UI paradigms we got stuck supporting odd/outdated functionality as designs shifted. Three great examples are pull to refresh, OnOffSwitch and the InfiniteProgress features. OnOffSwitch contained labels both in iOS & Android. On Android it was literally a button that … Switch, Progress and Pull to Refresh

One of the big “behind the scenes” motivations for our big build cloud migration was new server API’s. We now have a completely new backend and this made it easier to build a completely new Codename One App christened as “Codename One Build”. This app is currently in public beta on Android which you can … Build App Beta

A while back we announced the migration to the new build cloud. The migration worked very smoothly and mostly seamlessly but there was one caveat: client libraries must be up to date. This is a confusing point so hopefully this long overdue post will clarify it. The core of the problem is CodeNameOneBuildClient.jar. It’s a … TIP: Fix Issue with Missing Builds

We are thrilled to announce the release of Codename One 5.0 – Social. Codename One is an open source “Write Once Run Anywhere” mobile platform for Java and Kotlin developers!

WebSockets changed the way I do networking code. I combine them with WebServices to get the best of both worlds. But they still suffer in terms of reliability. With WebServices we have retries and a mostly transactional model. There is no permanent connection that should be re-established. With WebSockets a disconnect can be painful, up … TIP: Auto Reconnect Web Socket

Codename One 5.0 AKA Social will launch on September 19th. We pushed this release back to include support for crucial features such as JDK 11/OpenJDK support. With these features in place and a slew of other features we are gearing towards 5.0 GA. Tomorrow (Friday) we will push out plugin version 4.5 for all IDE’. … Preparing for Codename One 5.0 – Social

A while back we introduced Codename One Settings which superceded the old approach built in the IDE itself. This allowed us to consolidate code and move faster. That’s how we were able to implement more wizards for things like CSS support etc. Up until now we just left the old UI in place. People are … Removing the Old Preferences

The most secure password in the world is the one that doesn’t exist. You remove the user from the equation with a completely random key. To be fair this has some drawbacks and a password still exists somewhere (in your phone/email) but generally this works rather well…​ The trick is simple, if we want to … TIP: Activate via URL and Send Arguments

I wrote before about Crisp and how pleased we are over the migration to their service. Recently they started offering a new service of status page. This service runs on their servers and essentially monitors whether our service is down. Due to the complexity of our service not all of the pieces are monitored but … Status Monitor

In February I wrote about a new/improved way to build for iOS without the screenshot process. That was a bit ahead of its time as the xib build didn’t disable the screenshot process yet. This is now fixed and it’s turned on by default now. That means that if you send an iOS build it … No More iOS Screenshots
