Flutter apk installed but but cannot be found/opened

Question

I have been spending some weeks to try out to figure out this problem but I cannot manage to get it to work.

Context:

Flutter run

• I can perform "flutter run" and it will launch the app on my phone.
• After closing the app, I cannot see it in the apps page. I cannot search for it.
• The only way way to "reach" the app is to go to settings -> apps. Here I cannot open the app, the only option is to uninstall it.

Flutter build

• I can build an app. "flutter build apk" works fine.
• If a previous app version of the app is installed, It fails to install the apk.
• If I uninstall the previous app from settings -> apps, I can install the new apk. But I cannot open it. It only says "Done" and "Open" is grayed out.

What I have tried:

• Uninstall app from settings -> app
• flutter clean
• Removed signing from build.gradle
• Change singing release to debug
• flutter build apk -split-per-api
• This guide https://flutteragency.com/how-to-fix-release-apk-is-not-working-properly/
• Uninstalling "for all users"
• Running "adb shell am start com.example/.mainActivity" -> Works
• "adb shell pm list packages" shows my packet id

Additional information I don't know if it matters, but I recently added signing config and released an appbundle to the App Store. Might there be issues with conflicting appbundle and apk file?

My "flutter doctor -v"

Answer 1

I solved it

Problem was my intents.

How they were:

<intent-filter>
    <action android:name="android.intent.action.MAIN"/>
    <category android:name="android.intent.category.LAUNCHER"/>
    <action android:name="android.intent.action.VIEW" />          
    <category android:name="android.intent.category.DEFAULT" />        
    <category android:name="android.intent.category.BROWSABLE" /> 
</intent-filter>

How they should be:

<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" />            
    <category android:name="android.intent.category.DEFAULT" />        
    <category android:name="android.intent.category.BROWSABLE" /> 
</intent-filter>
