Android studio Manifest's android:exported="false"

Basically, android SDK 31 requires android: exported true when this activity is open and other activities require android: exported false

Example:

<?xml version="1.0" encoding="utf-8"?>

<manifest

xmlns:android="http://schemas.android.com/apk/res/android"  

package="com.mymundane.app">

<application

    android:allowBackup="true"

    android:icon="@mipmap/ic_launcher"

    android:label="com.mymundane.app"

    android:roundIcon="@mipmap/ic_launcher_round"

    android:supportsRtl="true"

    android:theme="@style/AppTheme"

    android:fullBackupContent="@xml/backup_descriptor">

    <activity

    android:name=".MainActivity"

        android:exported="true">

        <intent-filter>

            <action android:name="android.intent.action.MAIN" />

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

        </intent-filter>

    </activity>

</application>

</manifest>
