🚀 Android Studio Gradle Environment Variables Fix

Complete Solution for Windows 10/11

🚨 The Problem

Android Studio can't find Gradle because the environment variables aren't properly set up. This is a common issue that prevents projects from building.

🔧 Solution 1: Automatic Fix (Recommended)

Step 1: Download Gradle

  1. Go to Gradle Releases
  2. Download the latest stable version (currently 8.5)
  3. Extract to: C:\Gradle\gradle-8.5

Step 2: Set Environment Variables

  1. Press Win + R, type sysdm.cpl, press Enter
  2. Click Advanced tab → Environment Variables
  3. Under System Variables, click New
  4. Variable name: GRADLE_HOME
  5. Variable value: C:\Gradle\gradle-8.2
  6. Click OK

Step 3: Add to PATH

  1. In System Variables, find Path, click Edit
  2. Click New, add: %GRADLE_HOME%\bin
  3. Click OK on all dialogs

Step 4: Verify

  1. Open Command Prompt (new window)
  2. Type: gradle --version
  3. Should show Gradle version info

🛠️ Solution 2: Manual Android Studio Fix

Step 1: Open Android Studio

  1. Launch Android Studio
  2. Go to File → Settings (or Android Studio → Preferences on Mac)

Step 2: Configure Gradle

  1. Build, Execution, Deployment → Build Tools → Gradle
  2. Gradle JDK: Select your JDK (usually bundled)
  3. Use Gradle from: Select Specified location
  4. Gradle location: Browse to C:\Gradle\gradle-8.5
  5. Click Apply → OK

Step 3: Sync Project

  1. Click File → Sync Project with Gradle Files
  2. Or click the Sync Now button in the toolbar

🔍 Solution 3: Project-Level Fix

Step 1: Check Project Structure

  1. File → Project Structure
  2. Project tab: Verify Gradle Version
  3. Modules tab: Check Android Gradle Plugin Version

Step 2: Update Gradle Wrapper

  1. Open gradle/wrapper/gradle-wrapper.properties
  2. Update distributionUrl to latest version: 
    distributionUrl=https\://services.gradle.org/distributions/gradle-8.5-bin.zip

Step 3: Update Build Files

  1. Project-level build.gradle:

    buildscript {
    dependencies {
        classpath 'com.android.tools.build:gradle:8.2.0'
    }
}

  2. App-level build.gradle:

    android {
    compileSdk 34
    defaultConfig {
        minSdk 24
        targetSdk 34
    }
}

🚨 Troubleshooting Common Issues

Issue 1: "Gradle not found"
