Slow app startup caused by Amplify V1 DataStore in Android

[joshuamoreno1]

Description

I’m experiencing issues with my Flutter app on Android devices when using AWS Amplify DataStore. The app works perfectly on iOS devices, but it takes a long time to start on physical Android devices. During debugging, I found that it gets stuck at this line:

await Amplify.configure(amplifyconfig);

After 1 to 2 minutes, the app finally starts, but I also notice it slows down when DataStore synchronization begins. The operating system shows an alert indicating that the app is not responding, but if you wait, it eventually continues to function correctly.

The only thing that i see in logs related to DataStore is this:

However, this issue does not occur on iOS devices. I also checked the AppSync API logs in CloudWatch, and all synchronization queries and other requests are executed successfully without any errors. It’s possible that on Android, the operations are executed sequentially, whereas on iOS, they are executed in parallel.

I truly appreciate your help with this issue, as it is currently blocking the release of my app on the Google Play Store. I’ve only been able to launch the app on iOS so far due to this performance problem on Android. Your support means a lot to me, and I’m looking forward to any insights you can provide to resolve this.

Steps to Reproduce

1. Build the Android APK:

   • Develop a Flutter app using AWS Amplify DataStore.
   • Use the provided schema to define the data models in DataStore.
   • Set up user authentication and ensure that the app can log in users.
   • Build the APK for Android using Flutter tools.
   • Deploy the APK on a regular Android device, such as a Xiaomi smartphone.

2. Start the App with a Logged-In User:

   • Ensure a user is already logged in before starting the app.
   • When the app launches, it should begin loading data from DataStore models. Ensure that the data size is not too large (e.g., no more than 10 records per user).

3. Observe the App Behavior:

   • Notice that the app takes a significant amount of time to start (1-2 minutes).
   • Check logs to see the errors.
   • During the startup, observe that the app seems to be stuck at the await Amplify.configure(amplifyconfig); line.
   • Additionally, when DataStore synchronization begins, the app becomes slow, and the Android operating system may display a "App not responding" alert.
   • If you wait, the app eventually resumes and functions correctly.

Hi there!,

I recently update to that version and deployed in a Xiaomi and Samsung device but still having the same problem.

New Android plugin settings:

plugins {
    id "dev.flutter.flutter-plugin-loader" version "1.0.0"
    id "com.android.application" version "8.1.0" apply false
    id "org.jetbrains.kotlin.android" version "1.9.10" apply false
    id "com.google.gms.google-services" version "4.3.15" apply false
}

Do you know may be what could be the problem?

Thanks,

Hello @joshuamoreno1, currently Amplify Datastore v1 is in maintenance mode, I would recommend upgrading to v2 and see if the issue is resolved. Please see the documentation for reference.
