Webpage buttons do not open gallery on Andriod phone through webview on Flutter

I have given permissions in AndriodManifest.xml as follows :
Buttons do respond but they don't open the gallery. This web page works as expected on the browser of the phone.
Please guide. Am using latest Flutter.

'android:exported' property not set error despite having it set in android manifest

This is the error i get when i try to submit app to play store.
"You uploaded an APK or Android App Bundle which has an activity, activity alias, service or broadcast receiver with intent filter, but without 'android:exported' property set. This file can't be installed on Android 12 or higher. See: developer.android.com/about/versions/12/behavior-changes-12#exported"
This is my androidmanifest.xml file, i had set android:exported to true each time, but still its throwing this error, could someone please check and see what can be done to eliminate this error, here is my manifest file:

How does the premium version of Here sdk api work?

I signed up with Here sdk Api (Lite version) and I got a 'Freemium' account with an access_key_id and a secret_key as well. Now I want to upgrade my Freemium to Premium because I need the navigation tool for my application and they gave me an app code, api code and licence key (in the same account). when I built the application all I got is a blank page with a button and no errors in my terminal.
My Manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.here_map_nav">
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

android:label="{YOUR_LABEL_NAME}"
android:exported="false">
<intent-filter>
<action android:name="{YOUR_INTENT_NAME}"/>
</intent-filter>
</service>
</application>
By the way I don't know what to put in {YOUR_INTENT_NAME} and {YOUR_LABEL_NAME} . I don't know if it's the main problem or I should create an account for a premium version with my billing infos (since each account takes only one project)
Any help or clarifications would be appreciated!

try using below manifest.xml, it seems like action.VIEW is missing in yours.

Google Play Store - Find out why a device is incompatible

I published an android app in google playstore. Some clients complain about not being able to download the app as the play stores says it is "not compatible".
In google developer console, I can only see THAT a device is not supported. I want to know WHY a device is incompatible but that information is hidden from me.
Google has to have this information to determine compatibility, why is there no way to show this information to developers? Or am I wrong?
We'd really appreciate that feature, it is vital I think.
One device that fails, is for example: medion lifetab e10315
