Android Studio error: resource mipmap/ic_launcher not found

resource mipmap/ic_launcher not found

Android Studio is an essential Integrated Development Environment (IDE) for Android developers. It provides a powerful platform to create, debug, and deploy Android applications.

However, like any software, it can encounter errors that can sometimes be frustrating to deal with. One common error that developers may come across is the "Resource mipmap/ic_launcher not found" error.

In this section, we will delve into the details of this error, understand its meaning, and explore the possible causes behind it.

Additionally, we will discuss effective troubleshooting techniques to help you resolve this issue and get back to developing your Android applications smoothly.

What does "Resource mipmap/ic_launcher not found" mean?

When you encounter the error message "Resource mipmap/ic_launcher not found" in Android Studio, it typically indicates that the IDE is unable to locate the launcher icon for your application.

The launcher icon, represented by the ic_launcher resource, is an essential component of an Android application, as it serves as the icon displayed on the device's home screen or app launcher.

This error implies that Android Studio cannot find the specified launcher icon in the appropriate mipmap resource directory.

What causes the "Resource mipmap/ic_launcher not found" error?

There can be several reasons behind the "Resource mipmap/ic_launcher not found" error. Understanding these causes will help you diagnose and resolve the issue effectively. Let's explore the most common culprits:

1. Incorrect file location or naming:

Android Studio expects the launcher icon to be present in the mipmap directory, specifically within the res directory of your project structure. It further requires the icon file to be named ic_launcher. 

If the icon is not located in the expected directory or the file is named differently, Android Studio will not be able to find it, resulting in the error.

2. Mismatched file extension:

Another potential cause for this error is a mismatch between the expected file extension and the actual file format of the launcher icon.

By convention, Android expects the launcher icon to be a PNG (Portable Network Graphics) file with the extension .png. If your icon file is not in this format or does not have the correct extension, Android Studio will fail to recognize it.

3. Gradle build configuration issues:

The build.gradle file in your Android project contains crucial information and configurations for building your application.

If there are discrepancies or errors in this file, specifically within the applicationId or minSdkVersion settings, it can lead to the "Resource mipmap/ic_launcher not found" error. These configurations impact the generation and linking of resources, including the launcher icon.

4. Project sync or caching problems:

Android Studio relies on project synchronization and caching mechanisms to ensure efficient resource management.

However, sometimes these processes can encounter issues, resulting in resource inconsistencies. If the project sync or caching processes have not completed successfully or have been interrupted, it may lead to the "Resource mipmap/ic_launcher not found" error.

5. Troubleshooting the "Resource mipmap/ic_launcher not found" error:

Now that we have a better understanding of the causes behind the error, let's explore some troubleshooting techniques to resolve it:

6. Verify the icon file location and name:

Ensure that the launcher icon file is located in the mipmap directory within the res directory of your Android project.

Additionally, confirm that the file is named ic_launcher.png and has the correct file extension. If necessary, move or rename the file to match these requirements.

7. Check the icon file format:

Make sure that the launcher icon file is in the PNG format with the extension .png. If it is not in the correct format, convert it to a PNG file using an image editing tool and replace the existing icon file.

8. Examine the build.gradle file:

Inspect your project's build.gradle file and verify that the applicationId and minSdkVersion settings are correctly defined.

Ensure that the applicationId matches your package name and that the minSdkVersion is set to a valid API level.

9. Sync project with Gradle files:

To ensure the build.gradle changes are applied correctly, click on the "Sync Project with Gradle Files" button in the Android Studio toolbar.

This action synchronizes your project and updates the necessary configurations.

10. Clean and rebuild your project:

Perform a clean build of your project by selecting "Build" from the Android Studio menu and then clicking on "Clean Project." Afterward, rebuild the project by clicking on "Build" and then "Rebuild Project." This process will regenerate the resource files, including the launcher icon.

11. Invalidate caches and restart:

If the error persists, try invalidating caches and restarting Android Studio. To do this, go to "File" in the Android Studio menu, select "Invalidate Caches / Restart," and choose the appropriate option.

This action can resolve potential caching issues that may be causing the error.


The "Resource mipmap/ic_launcher not found" error in Android Studio can be easily resolved by following the troubleshooting techniques outlined in this section.

By understanding the causes behind the error and applying the appropriate solutions, you can quickly get back to developing your Android applications without unnecessary interruptions.

Remember to ensure the correct location, naming, and format of your launcher icon, review your build.gradle file, and perform necessary project synchronization and cleaning processes.

Android Studio provides a powerful environment for Android development, and with the right troubleshooting techniques, you can overcome any obstacles along the way.
