android-studio-3.0

I know that similar questions have been asked before, but my problem is new only after installing Android Studio 2.3, the latest version in March 2017. I have several years experience developing Android applications, and I have never encountered this problem before. After upgrading to version 2.3 of Android Studio, my emulator is no longer able to access the internet. I even uninstalled/reinstalled Android Studio 2.3 from scratch and created a new emulator, and I am still getting the same error. This is not an app problem. I can't even access the internet from Chrome, and I wasn't having this

I know about this questions: Failed to resolve: com.android.support:cardview-v7:26.0.0 android Could not resolve com.android.support:appcompat-v7:26.1.0 [duplicate] And I've read this documentations: Migrate to Android Plugin for Gradle 3.0.0 Migrating to Android 8.0 So I'm posting this question believing its not a duplicate. I've installed Android Studio 3.0.1. I didn't have any previous version before and I started a new project. Every setting in Gradle file have been set by Android Studio itself and I've checked them all. These are the file contents: build.gradle (Module:app) apply plugin:

When I updated my Android Studio to 3.0 in the stable channel and ran the project, I started getting the below error. Error:Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'. com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex I tried cleaning and rebuilding the project, but it didn't work. Any help will be appreciated.
