Possible solution:

  • I toggled gradle offline mode to fix this but it didn't work. Also cleared gradle caches yet the it failed to sync – aikd101 Feb 26 '21 at 05:54

Android Studio Arctic Fox | 2020.3.1 Canary 8 doesn't work internally.

I suggest migrating to Android Studio Arctic Fox (2020.3.1) Canary 7 with the following definitions:

build.gradle (project)

buildscript {
    dependencies {
        classpath "com.android.tools.build:gradle:7.0.0-alpha07"
    }
}

gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-6.8.1-bin.zip

Note: Do not use distributionUrl=.../gradle-6.8.2-bin.zip or classpath "...:7.0.0-alpha08" since they are associated with the Canary 8 compilation.

You also have to install Java 11 and configure it in the project

$ sudo apt-get install openjdk-11-jdk

JDK Location: /usr/lib/jvm/java-1.11.0-openjdk-amd64

build.gradle (:app)

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_11
        targetCompatibility JavaVersion.VERSION_11
    }
    kotlinOptions {
        jvmTarget = JavaVersion.VERSION_11.toString()
        useIR = true
    }
}

Good Luck

Install Java 11

I got this same error resolved by disabling controlled folder access in the Windows 10 defender firewall. Navigate to ***settings>update &security>windows security>virus & Threat protection>Ransomware protection>manage ransomware protection>***toggle the controlled folder access to be in grey so that the Gradle daemon can be allowed to make changes to the \usename.graddle\daemon\graddleversion folder
