How I Fixed Missing @mipmap/ic_launcher_background in Android Studio (Complete Guide) ✅

While working on my Android project, I encountered an issue where:

@mipmap/ic_launcher_background

was being referenced, but the file didn’t exist in my project. This caused confusion and potential build issues.

Here’s the exact solution that worked for me.


🔍 Understanding the Issue

In Android development, @mipmap/ic_launcher_background is not something you manually type or guess.

It refers to a real resource file inside your project:

res/mipmap/ic_launcher_background

If this file is missing, your launcher icon setup is incomplete.


⚠️ What NOT to Do

I initially considered selecting assets from this path:

C:\Program Files\Android\Android Studio\plugins\android\resources\images\asset_studio

This is incorrect ❌

  • These are internal Android Studio assets
  • They are not meant for app development use
  • Using them won’t properly fix your project

✅ The Correct Solution (Recommended)

The proper fix is to regenerate your launcher icons using Android Studio:

  1. Right-click on the res folder
  2. Select New → Image Asset
  3. Choose Launcher Icons (Adaptive and Legacy)
  4. Select your app icon:
    • Use your own logo (recommended)
    • Or choose Clip Art
  5. Click Next
  6. Click Finish

⚠️ “Icon Already Exists” Message

You may see a warning like:

An icon with the same name already exists

This is completely normal.

Simply continue — Android Studio will overwrite the old files and fix the setup automatically.


📂 What Gets Generated

After completing the process, Android Studio creates all required files:

  • mipmap-anydpi-v26/ic_launcher.xml
  • mipmap-anydpi-v26/ic_launcher_round.xml
  • ic_launcher_foreground.webp
  • ic_launcher_background.xml

These files define your adaptive launcher icon correctly.


🎯 Final Result

  • ✅ Missing resource issue resolved
  • ✅ No more reference errors
  • ✅ Adaptive icons properly configured
  • ✅ Project ready for production

💡 Helpful Tip

You can quickly locate any resource by:

  • Ctrl + Click (Windows)
  • Cmd + Click (Mac)

on a reference like @mipmap/ic_launcher_background.


🚀 Conclusion

The fastest and most reliable fix is:

New → Image Asset → Launcher Icons → Finish

No need to manually create files or search system folders.

This method fully resolved the issue in my project.
