Fiz exatamente como no vídeo:
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/Theme.Agenda">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
</application>E aparece esse erro:
Manifest merger failed : android:exported needs to be explicitly specified for . 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. See https://developer.android.com/guide/topics/manifest/activity-element#exported for details.
Obs: Na tag fica sublinhado de vermelho a primeira palavra activity. Quando eu passo o mouse encima aparece uma caixa de texto escrito: When using intent filters, please specify android:exported as well.
A versão do meu android studio é 2020.3.1 Patch 1
