android - Apps targeting Android 12 and higher are required to specify an explicit value for `android:exported`

Question

I've updated my SDK version to 31, afterward I get this error. this is my Gradle :

    android {
    compileSdkVersion 31

    defaultConfig {
        applicationId "com.persiandesigners.alldentshops"
        minSdkVersion 16
        targetSdkVersion 31
        vectorDrawables.useSupportLibrary = true
        versionCode 1
        versionName "1"
    }

    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
    lintOptions {
        checkReleaseBuilds false
        abortOnError false
    }
}

dependencies {
    implementation 'androidx.appcompat:appcompat:1.4.0'
    implementation 'androidx.recyclerview:recyclerview:1.2.0-alpha01'
    implementation 'androidx.cardview:cardview:1.0.0-alpha01'
    implementation 'com.google.android.material:material:1.2.0-alpha01'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.0-beta4'

I get this error : 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.

I did what it says, this is my manifest code :

<activity
        android:name="mypackage.MainActivity"
        android:exported="true"
        tools:node="merge"
        android:label="@string/app_name"
        android:screenOrientation="portrait"
        android:theme="@style/SplashScreenTheme"
        android:windowSoftInputMode="stateAlwaysHidden">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

this is the launcher activity and I've added android:exported tag , I tried clean and rebuilt but It didn't work . I still gets mergin error in manifest merge :

Merging Errors: Error: android:exported needs to be explicitly specified for <activity>. 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. forushgah_alldentalshop.app main manifest (this file)

it's pointed to the MainActivity activity

if you are using flutter ,may some deprecated lib in your app is causing this.. in my case: upgrading flutter_local_notifications to the latest version (now is 9.3.2) solved this error..

If your app targets Android 12 or higher and contains activities, services, or broadcast receivers that use intent filters, you must explicitly declare the android:exported attribute for these app components.

Please note this is applicable to all the activities, services, broadcast receivers that use an intent-filter.

Make the changes. Save it. Invalidate cache and restart android studio and check.

What if in my project theses errors happen but related to activity/services from AAR libraries? What can I do to solve it? I can't even modify theses files. – emanoellucas Dec 20 '22 at 22:11
