JRebel preserves your Fragment state and back stack or even ViewPager current page. It updates apps resource files and restarts Activities/Fragments so you could see changes. Warm swap is useful for updating app resources.

This is done by adding stub methods that will be executed the next time the method is called. But this swap is limited only to changing method bodies. This means that all objects could refer to an updated class and execute new code when their methods were called. It allows updating class bytecode in place, using the same class identity. Hot-swap updates your app without new APK. There are three types of code swaps: hot, warm and cold swaps.

So you save time by not rebuilding and packaging code parts that have not changed, fewer data pushed to the device over ADB and the dex2oat has a lot less work to do, compared to a full APK install. If APK is already installed on the device you just send small incremental patches that will be applied.

JRebel For Android and Instant Run are all about code or resources swapping. You will ask, why would I need such tool if I already use Android Studio’s “ Instant Run”, well, as their official page states - JRebel offers much more plus Instant Run has his issues. So here is some basic info about it straight from their official page - “JRebel for Android is an Android Studio and IntelliJ IDE plug-in that accelerates the development of Android applications by eliminating the time consuming full build, install and run cycle, saving hours of developer time annually.”
