Whatever the reason may be, changing the launcher activity of an Android application can help you enhance the functionality and visual appeal of your app.
Method 1: Using the AndroidManifest.xml File
The AndroidManifest.xml file is the main configuration file for an Android application. It contains important information about the app’s components, such as activities, services, and broadcast receivers.
Here’s how you can change the launcher activity of your Android Studio project using the AndroidManifest.xml file:
1. Open your Android Studio project and navigate to the app > src > main folder

3. Find the activity that you want to set as the launcher activity
4. Add the following line of code to the activity tag:
android:launchMode="singleTop"

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
6. Save the changes you made to the file and build the project
Pros:

- Does not require any third-party tools or plugins
Cons:
- You cannot change the launcher activity from the AndroidManifest.xml file if the application extends AppCompatActivity
- Requires basic knowledge of XML and AndroidManifest.xml file structure

1. Navigate to the Run Configuration dropdown at the top of the Android Studio screen and click "Edit Configurations"
2. In the Run Configuration dialog box, select the app module for which you want to change the launcher activity

4. In the "Activity" field, specify the name of the activity that you want to set as the launcher activity
5. Save the changes you made to the Run Configuration and run the project
Pros:

Method 3: Using the Android Studio Plugin
The Android Studio Plugin is a third-party plugin that allows developers to make various changes to their Android application projects without having to manually edit any files. Here’s how you can change the launcher activity using the Android Studio Plugin:
1. Click on "File" in the Android Studio toolbar and select "Settings"
2. In the Settings dialog box, select "Plugins" and click on "Browse Repositories"
3. Search for the "Activity Launcher" plugin and click on "Install"
4. Once the plugin is installed, close the Settings dialog box and restart Android Studio
5. Open your Android Studio project and navigate to the activity that you want to set as the launcher activity

7. Save the changes you made to the file and build the project
Pros:
- A quick and easy method
- Does not require any coding or manual XML editing
Cons:
- Requires an additional plugin to be installed
- Plugins can sometimes cause compatibility issues or bugs in the project
What to Do If You Can’t Change the Launcher Activity
In case you are unable to change the launcher activity of your Android application using any of the above methods, there are a few things that you can do to troubleshoot the issue:
1. Check if the activity you want to set as the launcher activity is included in the manifest file
2. Make sure that the activity is declared as a main activity using the "android.intent.category.LAUNCHER" category
3. Check if there are any errors or compatibility issues with your installed Android Studio version or the project files
4. Try rebuilding the project and restarting Android Studio
Bonus Tip
If you want to avoid the hassle of manually editing the XML files or using plugins, you can also use a code generator tool to generate the code for the launcher activity.
One such tool is the Android Studio Code Generator, which allows you to enter the activity name, package name, and other parameters and generate the necessary code for the activity.
