Deployed Flutter application to Google Play Store but it's stuck at the splash screen

Question

Deployed Flutter application to Google Play Store but it's stuck at the splash screen and never open I did match my AppID and still facing the same issue

Here is my manifest.xml:

<!-- TODO: Changed by Parveen Before merge 1 -->
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.mrbox.store">

    <uses-permission android:name="android.permission.INTERNET" />

    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <!--
    io.flutter.app.FlutterApplication is an android.app.Application that
    calls FlutterMain.startInitialization(this); in its onCreate method.
    In most cases you can leave this as-is, but you if you want to provide
    additional functionality it is fine to subclass or reimplement
    FlutterApplication and put your custom class here.

Answer 1

Things to try

1. Make sure flutter doctor -v runs without ANY complaints
2. Edit android/gradle.properties and add the flag: android.bundle.enableUncompressedNativeLibs=false
3. Do a flutter clean command
4. Try creating a release build using flutter build appbundle

Test Locally / Offline

1. download bundletool
2. Generate a set of APKs from your app bundle, following this guide
3. Deploy the app to your connected device(s) following this Guide

Works?

4. Upload your bundle to Google Play using the internal test track, or the alpha or beta channels to test the bundle before releasing it in production Instructions for doing this can be found here

5. Good Luck :)

Answer 2

Because it is not working after uploading on google play. then there might be some issue with your app signing. You can follow the steps here

Answer 3

I have faced issues like this when I used facebook login sdk, so I would suggest checking following:

1. Check if you have signed the apk/appbundle with proper release keystore

2. Check if you have opt in for google's automatic signing on playstore while deploying app

   2.1 If yes then it will change the sha-1 value which is used in facebook app for authentication, for it to work use the one generated by google in playstore

Answer 4

Assuming that you publish an App Bundle (.aab file) the issue can be related to the format itself since it is not testable via IDE. E.g. when running the app in Release mode on a device .apk is created and provisioned to it, not .aab.

What I did in the past to troubleshoot .aab (also had failures only with GPlay version, local Debug and Release modes worked fine) was to use Firebase Test Lab. You can run automated monkey tests on 5 physical devices and 15 virtual devices every day free-of-charge. Just log in to Firebase Console, cretae an empty project, go to Test, upload your .aab file, select devices (it's worth also to choose different locales) and wait for completion. After that check logs in test results, you might find answers there (in my cases there was an issue with localization resources which got broken while producing .aab release package).

This option can be esier/faster than splitting .aab locally with comand line into APKs and testing on a local device.

Answer 5

In my experience, try to check your database(sqlite) if created. Try to replace the path and check if the database is created properly.
