For me, adding android:exported="true" does not solve the problem

Question

see this question Application is not installed error, when launched from home screen shortcut

AndroidManifest.xml :

<application
            android:icon="@mipmap/ic_launcher"
            android:label="@string/app_name"
            android:roundIcon="@mipmap/ic_launcher_round"
            android:supportsRtl="true"
            android:theme="@style/Theme.AppTheme">
        <activity
                android:name=".ui.activity.MainActivity"
                android:screenOrientation="fullSensor"
                android:label="@string/app_name"
                android:exported="true"
                android:configChanges="orientation|screenSize">
            <intent-filter
                    >
                <action android:name="android.intent.action.MAIN"/>

                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
            <intent-filter
                    >
                <action android:name="android.intent.action.VIEW"/>
                <data android:scheme="app" android:host="appname"
                />

                <category android:name="android.intent.category.DEFAULT"/>
            </intent-filter>
            <nav-graph android:value="@navigation/nav_graph_main"
                    />
        </activity>

Please note the error text

android:exported needs to be explicitly specified for receiver

This means you have to look for receiver in main/dependencies manifest, if you find this tag on main manifest, you have to add the value of android:exported and if you can't find receiver tag inside the main manifest, then you should search inside other dependencies manifests, I will show you step by step

1- Open manifest file on Android Studio

2- At the bottom click on Merged Manifest

3- Open all the dependencies manifests in order and look for that does not contain a android:exported

4- I'm sure this tag will be found, after finding it just copy the whole tag and add it in the main manifest, do not forget to add the value of android:exported to it

Example:

receiver tag inside one of dependencies manifest file:

<receiver
        android:name="com.moduletop.push.UserPresentBroadcastReceiver"
        android:enabled="false" >
        <intent-filter>
            <action android:name="android.intent.action.USER_PRESENT" />
        </intent-filter>
</receiver>

Add this tag inside main manifest:

<receiver
        tools:node="merge"
        android:exported="false"
        android:name="com.moduletop.push.UserPresentBroadcastReceiver"
        android:enabled="false" >
        <intent-filter>
            <action android:name="android.intent.action.USER_PRESENT" />
        </intent-filter>
</receiver>
