Launch "Instant Run" from the command line

I am launching my Android application from Android Studio, and Instant Run is starting up, which is great. I want to run the same thing from the command line.

In the Android Studio event log, I see

22:00:28 Executing tasks: [:app:incrementalDevDebugSupportDex] 22:00:48 Gradle build finished in 20s 286ms 22:00:51 Instant Run applied code changes and restarted the current Activity.

So, I expected that I could run this task from the command line: ./gradlew :app:incrementalDevDebugSupportDex . However, it was not found:

 FAILURE: Build failed with an exception. * What went wrong: Task 'incrementalDevDebugSupportDex' not found in project ':app'.

Is there a way to start using Instant Run from the command line?

It is currently not possible to use instant start outside of Android Studio. This was mentioned on the Android Dev Summit, but I can’t remember exactly what conversation it was in.

You can start instant start from the command line as follows:

 ./gradlew clean :sample-app:assembleDebug -Pandroid.optional.compilation=INSTANT_DEV -Pandroid.injected.build.api=24

This is currently possible. You can run the command below to execute an instant start:

 ./gradlew :app:incremental"buildvarientname"DebugJavaCompilationSafeguard

You can add the same to the gradle task by adding the incremental"buildvarientname"DebugJavaCompilationSafeguard inside the task in the launch configuration window,
