'How to make my app immune to theme change?

Whenever the theme of the device is changed, two things happen:

  1. The colours change
  2. The activity is restarted

I don't want any of these to happen. The solutions already posted on Stack Overflow either deal with the first problem or the second one. I have already solved the first problem by deleting the night theme xml file and Theme.MaterialComponents.Light.DarkActionBar instead of DayNight. But I am unable to solve the second problem. The solutions on Stack Overflow are about how we can change the theme without recreating the activity. But what I want is nothing to happen. My activity should not react to theme change. Is there any way to do it?

In the app AndroidManifest.xml where your Activity is declared. You can set android:configChanges="uiMode"

For example:

    <activity
            android:name=".MainActivity"
            android:configChanges="uiMode"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
