Introduction
Changing an Android app's name might seem like a small tweak, but it can have a big impact. Whether you're rebranding, making the name more user-friendly, or just correcting a typo, updating the app name can make a difference in how users perceive your app.
Key Takeaways:
- Changing an app's name in Android Studio involves updating the `android:label` field in the `AndroidManifest.xml` file, ensuring users see the new name on their devices.
- Always back up your project before making changes, and test thoroughly to ensure the new app name appears correctly without any issues.
Understanding the Basics
What is AndroidManifest.xml?
The AndroidManifest.xml file is like the blueprint for your Android app. It tells the system about the app's components, permissions, and other essential information. Think of it as the heart of your project, pumping vital details to keep everything running smoothly.
Importance of android:label Field
Within this file, the android:label field is crucial. It defines the name that users see under the app icon on their device. Changing this field updates the app name, making it the key player in our mission to rename the app.
Preliminary Steps
Backup Your Project
Before diving into any changes, always backup your project. This ensures that if something goes wrong, you can revert to the original state without losing your work. It's like having a safety net for your code.
Development Environment Setup
Make sure your development environment is ready. This means having Android Studio installed and your project loaded. A properly set up environment ensures that you can make changes without running into unexpected issues.
Step-by-Step Guide to Change App Name
Accessing AndroidManifest.xml
First things first, you need to find the AndroidManifest.xml file. Open your Android Studio project. In the Project view, navigate to the app folder. From there, go to src > main > AndroidManifest.xml. Double-click to open it.
Modifying android:label Field
Once you’ve got the AndroidManifest.xml file open, look for the android:label field. It’s usually within the
xml
<application
android:label="OldAppName"
… >
…
Change the value of android:label to your new app name:
xml
<application
android:label="NewAppName"
… >
…
Save the file after making the change.
Handling Multiple Activities
If your app has multiple activities, each might have its own android:label. You’ll need to update those too. Look for
xml
…
Change the android:label for each activity as needed:
xml
…
Additional Considerations
Impact on App Icon
Changing the app name doesn’t affect the app icon. The icon is defined separately in the AndroidManifest.xml file using the android:icon attribute. No need to worry about your icon disappearing or changing.
Splash Screen Adjustments
If your splash screen displays the app name, you’ll need to update it too. This might involve changing text in your splash screen layout file or updating code in your splash screen activity. Check your res/layout folder for splash screen XML files or your SplashActivity.java (or .kt) file.
Testing the Changes
Building the Project
After making all the changes, you need to build your project. In Android Studio, click on Build in the top menu, then select Rebuild Project. This compiles your changes and prepares the app for testing.
Running the App
To see your changes in action, run the app. Click on the green play button in Android Studio. Choose an emulator or a connected device. Once the app launches, check the app name on the home screen and any splash screens to ensure everything looks good.
Advanced Customization
Dynamic App Name Changes
Sometimes, you might want your app's name to change based on certain conditions or user settings. This can be done dynamically at runtime. To achieve this, you can use the PackageManager class to set the app's label programmatically. Here's a quick rundown:
- Access PackageManager: Get an instance of
PackageManagerusinggetPackageManager(). - Get ComponentName: Use
new ComponentName(context, YourMainActivity.class)to create aComponentNameobject. - Set Label: Call
setComponentEnabledSettingwith the new label.
This way, the app name can change without needing to update AndroidManifest.xml each time.
Localization
If your app supports multiple languages, you might want to display different names based on the user's language settings. This is where localization comes in handy. To set different app names for different languages:
- Create String Resources: In your
res/valuesfolder, create separate folders for each language, likevalues-esfor Spanish. - Define App Name: In each folder, create a
strings.xmlfile and define the app name using the<string name="app_name">tag. - Reference in Manifest: In
AndroidManifest.xml, set theandroid:labelto@string/app_name.
This ensures that users see the app name in their preferred language, enhancing their experience.
Troubleshooting Common Issues
Build Errors
Changing the app name might sometimes lead to build errors. Common issues include:
- Resource Not Found: Ensure that the new name is correctly referenced in
strings.xml. - Manifest Errors: Double-check the
AndroidManifest.xmlfor any syntax errors or missing attributes.
If you encounter build errors, clean and rebuild the project. This often resolves minor issues.
App Not Reflecting Changes
If the app name change isn't showing up:
- Clear Cache: Sometimes, the old name is cached. Clear the app cache from the device settings.
- Reinstall App: Uninstalling and reinstalling the app can also help in reflecting the changes.
- Check Manifest: Ensure that the
android:labelfield is correctly updated and saved.
These steps should help in making sure the new app name is displayed correctly.
Best Practices
Consistent Naming
Maintaining consistency in app naming across different platforms is crucial. Ensure that the app name is the same on Android, iOS, and any other platforms you support. This helps in building a strong brand identity and avoids confusion among users.
User Experience
Changing the app name can impact user experience. Frequent changes might confuse users, so it's best to keep the name consistent unless there's a significant reason for the change. When you do change the name, communicate it clearly through app updates or notifications to keep users informed.
Final Thoughts
All in all, renaming an Android app might seem like a small task, but it can significantly impact user perception. From modifying the AndroidManifest.xml file to ensuring consistency across multiple activities and languages, every step matters. Always backup your project before making changes, and test thoroughly to catch any issues early. Remember, the app name is a core part of your brand’s identity; keeping it consistent and user-friendly is key. With these steps, you’re set to make your app name change smoothly and effectively, ensuring users see the new name without a hitch. Happy coding!

Tips for Best Use
Keep it Simple: Choose a name that's easy to spell and remember. Avoid complex words or phrases.
Reflect the Purpose: Ensure the name hints at what the app does. For example, a photo editing app could include words like "Photo" or "Edit."
Avoid Special Characters: Stick to letters and numbers. Special characters can cause issues with search engines and app stores.
Check Availability: Make sure the name isn't already taken. Search app stores and domain registries.
Think Long-Term: Choose a name that will still make sense if the app expands its features in the future.
Test with Users: Get feedback from potential users. See if they understand the app's purpose just by hearing the name.
Consider SEO: Use keywords that people might use to search for apps like yours. This helps in app store rankings.
Stay Unique: Stand out from competitors. Avoid names that are too similar to existing apps.
Legal Check: Ensure the name doesn't infringe on any trademarks. Consult a legal expert if unsure.
Localization: If targeting multiple countries, check that the name works well in different languages and cultures.
