To reload changes on the fly the agent will call Activity.recreate for the top-most activity in the stack. Upon modification, the relevant DEX files are rebuilt and sent to the agent, together with modified resources, without having to recreate or reinstall a new APK. Then the actual application (DEX files and resources) are sent to the agent via ADB, and the agent loads them as the running app.

Android, on the other hand, doesn't even use a Java Virtual Machine: until Android 4.0, Java code was compiled into DEX files, which were then interpreted by the Dalvik virtual machine (after the necessary packaging and installation) from Android 5.0 onwards, the DEX files are then recompiled to native machine code by the device itself therefore a different approach was needed.Īs ZeroTurnaround explains, JRebel for Android modifies the project's Gradle build to create a shell APK which only contains the JRebel for Android agent this is the only APK that needs to be installed in the Android device being used for development. In the case of JRebel, code changes in Java would be compiled, and the resulted bytecode inserted into the running web application through class reloading. Technical detailsĭespite providing analogous functionality, the different underlying technologies mean that traditional JRebel and JRebel for Android work in rather different ways. JRebel for Android in Action from Official ZeroTurnaround Account on Vimeo. A demonstration of how this works can be seen in the following video. The JRebel for Android plugin will add new items to the Run menu in Android Studio and modify the Gradle build file to include the tools that allow the code to be hot swapped into the running application. With the feedback from the beta program, an early access release was made available in September 2015. To fill this need, ZeroTurnaround started work on JRebel for Android in 2014, producing a beta version in April 2015.

For this reason, a hot swap functionality has been requested by the development community for at least two years. On top of the delay that this process entails, if the feature being modified is a few steps down a particular workflow, the developer will have to walk through such workflow every time a change is deployed. Every time a developer wants to see the effect of a code change, the Android application needs to be recompiled, repackaged, reinstalled into the Android device and restarted.

ZeroTurnaround offers a 21-day free trial, with prices beginning at $49/year.Ī common complaint from Android developers is how the underlying technology imposes a rather slow feedback loop.

JRebel for Android is available for Android Studio from the JetBrains plugin repository, and supports all phones and tablets running Android 4.0 or later. Use these dependencies for the project build.ZeroTurnaround has announced the first stable release of JRebel for Android, the Android version of their popular plugin to modify running applications without having to redeploy or restart.
