I changed the Select Run/Debug Configuration from my MainActivity to App and it started working. Select App configuration snapshot:

Answer 2

First check a Launch Activity is set in your 'manifest.xml' file has:

<activity android:name=".{activityName}">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

If this is set correctly, next check your run/debug configuration is set to 'App',

If the 'App' configuration is missing - you will need to add it by first selecting 'Edit Confurations'

If you do not have a 'App' configuration you will need to create one, else select you 'App' configuration and skip the creating steps. Also if your configuration is corrupt you may need to delete it but first backup your project. To delete a corrupt configuration, select it by expanding the 'Android App' node and chose the '-' button.

To create a new configuration, select the '+' button and select 'Android App'

If you have just created the configuration you will be presented with the following default name value of 'Unnamed' and module will have the value '<no module>' then hit 'Apply' and 'OK'.

Set this the name to 'App' and select 'app' as the module.

Next select 'App' as the run configuration and Run.

Thats it!

Just Select App from dropdown menu with Run(green play icon). it will run the whole the App not the specific Activity. if it doesn't help try to use in that activity in ManiFest.xml file. thankyou

If you're trying to launch a specific activity instead of running the launcher one. When you select that activity. the android studio might through this error, Either you need to make it launcher activity, just like answered by few others. or you need to add android:exported="true" inside your activity tag inside manifest. It allows any external tool to run your specific activity directly without making it a launcher activity
