Flutter app don't reach server on android

I develop a full stack application. I use flutter as frontend and nodejs + express js as backend.

I built and released ios version to testflight and everywthing worksfine.

But when I install apk on android physical devise(galaxy j7 and galaxy s20) something went wrong. When I try to retrive some data through application(for example user data), I get nothing.

I use hosting and there is PM2 installed so I can see console.log of my backend and there is nothing too. It just seems that application don't address server.

Can anybody tell me where could be mistake?

I also check android emulator and there everything was ok.

Solution

  • can you check if you have Internet permission in your AndroidManifest.xml file for main : android/app/src/main/AndroidManifest.xml ?

    If not you can add it like this

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