Solutions to the Can not extract resource error

Now that we’ve covered the causes, let’s get to the solutions! Try these steps in sequence to resolve the error:

Solution 1: Check your XML syntax

Open your XML file and carefully review the syntax. Look for any typos, incorrect attributes, or missing closing tags. Make sure your XML is well-formed and follows the Android XML guidelines.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <!-- Your layout content here -->

</LinearLayout>

Solution 2: Check for duplicate resource IDs

Search your entire project for duplicate resource IDs. You can use Android Studio’s built-in search function (Ctrl + Shift + F on Windows or Command + Shift + F on Mac) to find duplicate IDs.

Search for	Replace with
{@+id/duplicate_id}	{@+id/unique_id}

Solution 3: Clean and rebuild your project

Sometimes, a simple clean and rebuild can resolve the issue. In Android Studio, go to:

1. Build

3. Rebuild Project

This will remove any temporary files and rebuild your project from scratch.

Solution 4: Invalidate caches and restart

Invalidating the caches and restarting Android Studio can also resolve the issue. Go to:

1. File
2. Invalidate Caches / Restart

This will remove any cached data and restart Android Studio.

Solution 5: Check library versions

Verify that all your library versions are compatible with each other and with your project. Check your build.gradle file for any version conflicts.

dependencies {
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:design:28.0.0'
}

Solution 6: Update Gradle configuration

Check your Gradle configuration files (build.gradle and gradle.properties) for any issues. Make sure you’re using the correct Gradle version and that your configuration is up-to-date.

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.0.0'
    }
}

Solution 7: Try a fresh project

If all else fails, try creating a fresh project and gradually adding your code and resources. This will help you identify if the issue is specific to your project or a general Android Studio problem.
