Is it possible to access onCreate method of Application class?

Extensions
#1

Hi,

I’m building an extension to log events with Facebook Analytics.
According to the documentation, we need to call some methods when the app is created:

package com.example.hellofacebook;

import android.app.Application;

import com.facebook.FacebookSdk;
import com.facebook.appevents.AppEventsLogger;

public class HelloFacebookSampleApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        FacebookSdk.sdkInitialize(getApplicationContext());
        AppEventsLogger.activateApp(this);
    }
}

Is there a way to achieve the same in an extension?

I’ve tried this in my extension:

@SimpleFunction(description = "Initialize SDK")
    public void Initialize(String facebookAppId) {
        FacebookSdk.setApplicationId(facebookAppId);
        FacebookSdk.sdkInitialize(this.container.$context().getApplicationContext());
        AppEventsLogger.activateApp(this.container.$context().getApplication());
        this.logger = AppEventsLogger.newLogger(this.container.$context());
    }

I call it the Initialize block of the screen I want to log events but it doesn’t seem to work. I got this warning in logcat: “W/com.facebook.appevents.internal.ActivityLifecycleTracker: Unexpected activity pause without a matching activity resume. Logging data may be incorrect. Make sure you call activateApp from your Application’s onCreate method”

Thank you for your help!

There should be a OncreateListener at the App Inventor sources.
EDIT:

Looks like there is only a OnCreateOptionsMenuListener listener…

You should open a issue at her github page with your request.

Thank you for your quick reply.

I was not aware of this listener.
I’ve opened an issue.

Thanks
