CONNECTION_ERROR CODE 5 on Android 9

Question

Hi.

I successfully created a multiplayer demo game based on the example:

http://appwarp.shephertz.com/game-development-center/java-multiplayer-libgdx-tutorial/

The project is successfully running on desktop and Android versions 6.0 and 7.1.1. But the initialization doesn't work on the Xiaomi Redmi Note 5 Android 9:

CONNECTION_ERROR CODE 5 in onConnectDone(ConnectEvent connectEvent)

 

App42MultiPlayerGamingSDK.jar (version 2.3)

In build.gradle targetSdkVersion 29

 

Answer 1

I solved this problem. Add a line to the AndroidManifest.xml:

<application
...
android:usesCleartextTraffic="true"
...>

Apparently AppWarp uses requests without encryption.
