App won't run under Android Studio 2.0, after upgrading from 1.5

Question

I recently upgraded my Android Studio from 1.5 to 2.0. My app would build and run nicely on Android 1.5. Now, when I try run the app on my smartphone, it gives me this error:

Error:Execution failed for task ':app:transformClassesWithInstantRunForDebug'.
> 24

When opening my project on Android Studio 2.0, a message box appeared, telling me to upgrade my gradle to version 2, which I did. I am not sure why I am getting this error.

Here is the output I get as I try to run the app on my phone:

Answer 1

Delete build dir

Don't disable Instant Run! It is useful. Instead, try deleting the contents of your build directory, and then rebuilding.

appName/build and/or appName/app/build

Alternatively, clean build

A less brute force option to try is to clean the build.

Build -> Clean Project or Build -> Rebuild Project

Answer 2

Try to disable the Instant Run option in Android Studio 2.0

This is helped me.

Answer 3

Have you ever seen a message box like below when you build your project with Android Studio 2.0 ?

If not , watch out for this window which will possibly appear when you build your project with studio 2.0 then update it. that will change your Gradle-plugin version to 'com.android.tools.build:gradle:2.0.0' and Gradle-wrapper to distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip or you can do it yourself .

Answer 4

try to uncheck the instant run on settings.. search instant on the settings and youll see it. or maybe you havemt changed the path of your gradle to the new one?
