Manifest merger failed: Apps targeting Android 12 and higher are required to specify an explicit value for android: exported when the corresponding component has an intent filter defined

Apps targeting Android 12 and higher are required to specify an explicit value for android: exported when the corresponding component has an intent filter defined .

You need to specify android:exported="false" or android:exported="true"

Manifest:

<activity
    android:name=".MainActivity"
    android:exported="true"
    android:theme="@style/Theme.MyApplication.NoActionBar">

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

</activity>

Add  android:exported="true" to your launcher activity
