Android Studio 3.0 Canary 2: attribute 'android:versionCode' not found

Question

I've updated Android Studio to the latest canary build and now I can't run my app.

Every time when I try to build the project I get the following error:

Error:F:\...\**app_name**\app\build\intermediates\instant-run-support\debug\slice_0\AndroidManifest.xml:2 attribute 'android:versionCode' not found 

I tried to manually open the file and the attribute is clearly there:

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"       package="****"       android:versionCode="1"       android:versionName="1.0"       split="lib_slice_0_apk"> </manifest> 

I've tried to clean the project, invalidate cache, restart android studio but nothing helped.

This is my build.gradle (app) file:

apply plugin: 'com.android.application'  apply plugin: 'kotlin-android'  android {     compileSdkVersion 25     buildToolsVersion "25.0.3"     defaultConfig {         applicationId "****"         minSdkVersion 16         targetSdkVersion 25         versionCode 1         versionName "1.0"         testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"     }     buildTypes {         release {             minifyEnabled false             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'         }     } }  dependencies {     compile fileTree(include: ['*.jar'], dir: 'libs')     androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {         exclude group: 'com.android.support', module: 'support-annotations'     })     compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"     compile 'com.android.support:appcompat-v7:25.3.1'     testCompile 'junit:junit:4.12'     compile 'com.android.support.constraint:constraint-layout:1.0.2'     compile 'com.android.support:design:25.3.1'     compile 'com.android.support:cardview-v7:25.3.1'     compile 'com.squareup.picasso:picasso:2.5.2' }

This issue is strictly related to Instant Run. Workaround: disable it inside File -> Settings/Preferences. This will at least allow you to run your app in the Canary version of AS.
