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. ✅

How to Fix the LaTeX “Not allowed in LR mode” Error When Highlighting Revisions If you highlight changes in a LaTeX manuscript using commands such as \change{...} , \rev{...} , or \hl{...} , you may eventually run into this error: LaTeX Error: Not allowed in LR mode. This often confuses authors, especially during journal revisions. Fortunately, the cause is simple: you placed a command inside the highlight block that LaTeX does not allow in LR mode. 🔍 Why This Error Happens Highlight macros like \change{} put LaTeX into a restricted text-only mode called LR mode . Inside LR mode, LaTeX only accepts basic text . The following commands cannot appear inside a highlight block: Section commands: \section , \subsection , \subsubsection Figures and tables List environments ( itemize , enumerate ) Math environments ( equation , align ) Captions and labels ( \caption , \label ) Any \begin{...} / \end{...} environment If even one of these appears in...

NR-V2X Mode 2 in ns-3 In 5G NR-V2X, vehicles communicate directly using sidelink. Two modes exist: Mode 1: gNB schedules sidelink resources. Mode 2: UEs autonomously select sidelink resources (no gNB needed). Mode 2 is especially important for vehicular networks (IoV), where cars must exchange safety messages without relying on infrastructure. In ns-3, the NrHelper class is used to: Create UE devices with sidelink PHY/MAC layers. Attach them to Bandwidth Parts (BWPs) and spectrum channels. Configure sidelink attributes such as: SidelinkMode = 2 (autonomous) SidelinkPeriod (resource pool periodicity) SidelinkSubchannelSize (RB grouping)
