TIP: Use Android Gradle Dependencies in Native Code

Integrating a native OS library isn't hard but it sometimes requires some juggling. Most instructions target developers working with xcode or Android Studio & you need to twist your head around them. In Android the steps for integration in most modern libraries include a gradle dependency.

Questions of the Week 41

We are releasing a small Eclipse update today, it's small because it isn't a full release that includes the latest features/libraries but rather a minor bug fix to the previous release which was missing the UWP build target. One of the biggest changes this week is the fix for the build performance issue mentioned below. It might also speed up general app performance for some use cases!

Intercom Support

We use intercom.io for our website support system you can see it as the chat button on the bottom right of the page. The true value of this tool is in it's ability to deliver a unified interface everywhere, normally this stretches into native mobile apps as well. As a result we decided to port the native intercom device API to Codename One so it will be easy to deploy everywhere.

I recently had to debug some code on Android Studio and was reminded how awful that IDE really is. IntelliJ is a pretty good IDE but Android Studio is remarkably slow even for trivial projects... One of the things that make it slow (besides RAM usage) is the approach of downloading everything it needs dynamically.

Can Execute Hint

Display.canExecute(url) provides us with a generic tool to test the availability of a feature before executing a command. This is very useful for inter-app communications and allows us to achieve various things such as launching Google Map instead of Apple Maps on iOS.

Jailbreak/Rooting Detection

iOS & Android are walled gardens which is both a blessing and a curse. Looking at the bright side the walled garden aspect of locked down devices means the devices are more secure by nature. E.g. on a PC that was compromised I can detect the banking details of a user logging into a bank. But on a phone it would be much harder due to the deep process isolation.
