Configuration MainActivity.class issue / Error 4

[Sulorb]

Hello,

I'm struggling to install correctly the plugin. The only thing I didn't succeed from the setup is this part:

Then on your MainActivity.class file you will need to import and register the plugin in your onCreate method:
@Override public void onCreate(Bundle savedInstanceState) { registerPlugin(CapacitorGameConnectPlugin.class); super.onCreate(savedInstanceState); }

Do I have to put it in android/app/src/main/java/io/ionic/start/MainActivity.java ?

I tried like this:

`
package app.myapp.www;

import com.getcapacitor.BridgeActivity;

public class MainActivity extends BridgeActivity {
@OverRide
public void onCreate(Bundle savedInstanceState) {
registerPlugin(CapacitorGameConnectPlugin.class);
super.onCreate(savedInstanceState);
}
}
`

But when I run it to my android device it returns me this error:

symbol: class Bundle [capacitor] location: class MainActivity [capacitor] C:\Users\alexi\OneDrive\...\android\app\src\main\java\io\ionic\starter\MainActivity.java:8: error: cannot find symbol [capacitor] registerPlugin(CapacitorGameConnectPlugin.class); [capacitor] ^ [capacitor] symbol: class CapacitorGameConnectPlugin [capacitor] location: class MainActivity [capacitor] 2 errors [capacitor] [capacitor] FAILURE: Build failed with an exception.

Also without that part I succeed to run it on my phone but when I try to signIn as follows:

import { CapacitorGameConnect } from '@openforge/capacitor-game-connect'; ... const user = await CapacitorGameConnect.signIn();

It returns me this error in the inspector console:

`
ERROR Error: 4:
at returnResult (VM3:912:32)
at win.androidBridge.onmessage (VM3:887:21)
handleError @ main.2b90b40a20af0514.js:1

`

Please help me finish the setup, I don't know what the "Error 4" means and how to "register the plugin in your onCreate method". 🙏

I think my message was a bit confusing, but basically I had the common "error 4". Just solved it, here is what I did, maybe it'll help someone here:

• In the strings.xml, i wrognly put my package id instead of my game project id (that you'll find under your project name in the google play console):
  <string translatable="false" name="game_services_project_id"> 0123456789</string>

The MainActivity.java fil must look like this:

`package io.ionic.starter;

import android.os.Bundle;

import com.getcapacitor.BridgeActivity;
import com.openforge.capacitorgameconnect.CapacitorGameConnectPlugin;

public class MainActivity extends BridgeActivity {
@OverRide
public void onCreate(Bundle savedInstanceState) {
registerPlugin(CapacitorGameConnectPlugin.class);
super.onCreate(savedInstanceState);
}
}
`

Please update your readme by adding this important line otherwise there is a bug:

import com.openforge.capacitorgameconnect.CapacitorGameConnectPlugin;

The error 4 apparently comes from a bad SHA1 in the oAuth. After reading the troubleshoot of this official documentation:
https://developers.google.com/games/services/console/enabling

I noticed you can easily debug directly your app by putting a SHA1 from the debug keystore and it'll work directly:

To get the debug certificate fingerprint, run the following command:

keytool -list -keystore -v

Note: On Windows, the debug keystore is located at C:\Users<USERNAME>.android\debug.keystore. On Mac or Linux, the debug keystore is typically located at ~/.android/debug.keystore.

I will have to change this SHA1 once the app is available in the Store, but you can at least debug your app with this debut keystore.
