>Beginning with Android Studio 3.2 Canary 11, the source for AAPT2 (Android Asset Packaging Tool 2) is Google's Maven repository. > >To use AAPT2, make sure that you have a google() dependency in your build.gradle file, as shown here:

buildscript {
  repositories {
      google() // here
      jcenter()
  }
  dependencies {
      classpath 'com.android.tools.build:gradle:3.2.0-alpha12'
  }
} 
allprojects {
  repositories {
      google() // and here
      jcenter()
  }
}

>The new version of AAPT2 fixes many issues, including improved handling of non-ASCII characters on Windows.

Adding the repositories in the buildscript is not sufficient, you need to add it also in allprojects.

Solution 2 - Android

Are you opening a very old project? If so, make sure your app's build.gradle has:

apply plugin: 'com.android.application'

repositories {
    google()
    jcenter()
}

(That solved it for me anyways)

Solution 3 - Android

Just add google() on your buidscript and allprojects then rebuild the project.

buildscript {
    repositories {
        google() // `enter code here`
    }
 }

allprojects {
    repositories {
        google() // `<-- here`
    }
}

Solution 4 - Android

I am in Iran, and some of google's repositories are restricted in my location. When I changed my IP to another country, this problem was solved. It seems you may have an internet connection problem when this error happens.

Solution 5 - Android

Update your app's build.grade file dependency with the updated version of grade

dependencies {    
  classpath 'com.android.tools.build:gradle:3.5.3'   
}

Follow android studio suggestion of the version to update to. after your grade classpath update and re-sync your app.

After all this restart your android studio.

Solution 6 - Android

I had this error message:

> Could not download aapt2-osx.jar > (com.android.tools.build:aapt2:3.5.0-5435860): No cached version > available for offline mode

Even if I had defined all the necessary dependencies for my proyect, and the right configuration into my build.gradle:

apply plugin: 'com.android.application'

repositories {
    google()
    jcenter()
}

The error still happening, but this message gave me a clue of what was happening:

> No cached version available for offline mode

So I discovered that I was working offline, you need to uncheck the "offline mode" then Android Studio will be able to download the necessary resources to create the project.

When your project is working again, you can check again to work offlin.

Solution 7 - Android

I resolve this issue by changing the "distributionUrl" in android/gradle/gradle-wrapper.properties.

The default value was https\://services.gradle.org/distributions/gradle-4.10.2-all.zip and I changed it to https\://services.gradle.org/distributions/gradle-5.4.1-all.zip and the error is gone.

Solution 8 - Android

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
        google()  //导入旧版本项目时，一般来说该处依赖会在更改classpath中gradle版本是自动添加
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'
        classpath 'com.google.gms:google-services:3.0.0'
    }
}

allprojects {
    repositories {
       /*
        解决报错：Could not find com.android.tools.build:aapt2:3.3.0-5013011.
        Beginning with Android Studio 3.2 Canary 11, the source for AAPT2 (Android Asset Packaging Tool 2) is Google's Maven repository.
        To use AAPT2, make sure that you have a google() dependency in your build.gradle file, as shown here:
        */
        google() //但是此处不会，需要自主添加
        jcenter()
    }
}

Solution 12 - Android

In my case, I was able to resolve it by updating "Android SDK Build-Tools" to the latest version.

In Android studio, Goto Tools -> SDK Manager -> Select SDK tools tab -> check whether any update available for the Android SDK Build - Tools (updated to the latest v30.0.0).

enter image description here

Solution 13 - Android

Go to settings.gradle and remove projectRoot.name file

Solution 14 - Android

Problem happened to me when i opened my old project

Can be fixed by upgrading the tools gradle

classpath "com.android.tools.build:gradle:4.0.2"

Solution 15 - Android

Unfortunality non of the answers above was complete enough, however this work for me . Just make sure your build.gradel has all of the following

buildscript {
    repositories {
        google() // Check if this Google exists and is in the first
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.0'
    }
}

allprojects {
    repositories {
        google() // Check if this Google exists and is in the first
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Solution 16 - Android

you need to tape in the: build.gradle () and type google() and this option do it in buildscript & allproject section

Solution 17 - Android

if google() not fixied then File -> Setting -> Build, Execution, Deployment -> Gradle

Then Uncheck Ofline Work, Done.
