The initially built APK has to be modified to support these swaps. There are 3 types of swaps in total - hot swap, warm swap and cold swap. Once on the device, the dex2oat has a lot less work to do, compared to a full APK install.Less data needs to be pushed to the device over ADB.The build process no longer needs to package and build the code parts that have not changed - just rebuild the deltas.This is a huge timesaver in a multitude of ways: When the APK is present on the target device, you can start sending over small, incremental patches that will be applied. This means that you install the APK just once. Swapping codeīoth Instant Run and JRebel for Android are all about “swapping” code or resources, live, inside a runtime environment. Today, I will provide an overview of how Google’s Instant Run and JRebel for Android handle code and resource changes. A tool that is approximately 1.5 years old, bringing the same technology to Android developers.
JRebel, the Java code reloading tool for Java SE/EE, has been enhancing developers’ lives for the past 8 years. The idea itself is nothing that new - it has been present in Java for over a decade.
Delivering faster build times to Android developers by supporting hot swapping code and resources in an already running application. Complete with a totally new feature titled “Instant Run”. Since Android Studio 2.0 has finally been released, this is a good time to compare the two.īack in November of 2015, Google announced Android Studio 2.0. People keep asking us about the differences between JRebel for Android and Google’s own Instant Run.
