For a while now, Kotlin has automatically converted single-method Java interfaces into lambdas, for better readability. One of the main features of 1.4 is SAM conversion for Kotlin interfaces. Android Studio now supports Kotlin 1.4, which comes with a whole bunch of new stuff. Because of all these advantages, Google officially recommends Kotlin as the language to use for Android development.įirst, there are some new features in Kotlin itself. It's more concise than Java, has various helper methods, supports extension functions, and has a whole lot more that makes it more pleasant to use than Java. Kotlin has become probably the most popular language for Android development. Now let's talk about Kotlin and AndroidX. Lastly (for this sub-list), app builds should be even faster for devices running Android 11 or later. At the time of writing this, it isn't exactly clear what this means, but Google says it will enable faster and more integrated automated testing.

The Android Emulator is now part of Android Studio. Well, with Android Studio 4.2, all you need is a device running Android 11 or later, and you'll be able to get Wireless ADB running in no time. You either need to fiddle around in normal ADB or have a rooted device. Unfortunately, it can be difficult to get it enabled. This feature of ADB lets you connect to your device using its IP address instead of a cable. If you've done a lot of developing (or tinkering), you probably know about Wireless ADB. There are a ton of new features in these releases, so we're only going to go over some of the more interesting ones. Google has released two new versions: 4.1 in Beta, and 4.2 in Canary.
