Can't run app with Instant Run on Android Studio 3.0

问题

I've updated to Android Studio 3.0 and now I cannot run the app with Instant Run enabled.

I get 'Execution failed for task' due to a java.io.FileNotFoundException because it can't find the apk under

../build/intermediates/instant-run-resources/resources-production/

Any idea how to overcome this so that I can run the project with Instant Run?

I'm not sure where to find the missing apk file or how to change the path to look for it in.

回答1:

Have your settings as below,

Otherwise try to clean and re-install (after uninstalling exsisting apk) application.

I found the problem and the solution.

In my case the cause was dexcount-gradle-plugin. The plugin is expecting that the package task produces an APK, but that is not true anymore on Instant Run. So they released a new version that disables the process when running with Instant Run.

So I just had to update dexcount to the latest version.

Configure your project for Instant Run

Android Studio enables Instant Run by default for projects built using Android plugin for Gradle 2.3.0 and higher. Please checkout this LINK to configure your project for instant run.
