When I changed the target and compile SDK version from 30 to 31 I get an error. Something similar to this question, but it has no answers.

Error: 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.

But all activities with intent-filter already have andoird:exported attribute. My android-manifest:


<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.bsuir.testapp.presentation">

        android:supportsRtl="true">

            android:exported="false">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".screens.history.view.HistoryActivity"
            android:label="@string/history_name"
            android:theme="@style/Theme.ComposePagination.NoActionBar"
            android:screenOrientation="portrait"/>
        <activity
            android:name=".screens.availabledevices.view.AvailableDevicesActivity"
            android:label="@string/devices_name"
            android:theme="@style/Theme.ComposePagination.NoActionBar"
            android:screenOrientation="portrait"/>
        <activity
            android:name=".screens.settings.view.SettingsActivity"
            android:label="@string/settings_name"
            android:theme="@style/Theme.ComposePagination.NoActionBar"
            android:screenOrientation="portrait"/>
        <activity
            android:name=".screens.dashboard.view.DashboardActivity"
            android:label="@string/app_name"
            android:screenOrientation="portrait"/>

        <provider
            android:name="androidx.core.content.FileProvider"
            android:authorities="${applicationId}.provider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/file_provider_paths" />
        </provider>
    </application>

</manifest>

What could be causing the error?

Update android:exported="true" only for Launcher activity and remaining Activities android:exported="false"
