Java Question Need Help with ba.activity

[itgirl]

Hello guys im trying to make a very simple wrapper for RevMob but i can't seem to get it right ba.activity always return NULL !! even with the "@ActivityObject".
so any advice guys ?

package revmob.test.wrapper;
import com.revmob.RevMob;
import android.app.Activity;
import anywheresoftware.b4a.BA;
import anywheresoftware.b4a.BA.ActivityObject;
import anywheresoftware.b4a.BA.ShortName;


@ActivityObject
@ShortName("RevmobTest")
public class revmob extends Activity {
    private BA ba;
    private String eventName;
    private RevMob revmob;
    
    public void InitializeRevMob(BA ba, String EventName )
    {
    this.ba = ba;
    revmob.start(ba.activity);
    revmob.showFullscreen(ba.activity);

    }
}

Your code looks correct. Make sure to regenerate the XML file after you added the @ActivityObject annotation.

Note that for simple wrappers it is usually simpler to use JavaObject: Accesing third party Jar with #Additionaljar and JavaObjec

Hey Erel thanks for answering, infact i have regenerated the XML and i have tried to compile using eclipse and SLC , no luck at all just keeps giving NULL. and yeah i know about the JavaObject but this is not a simple wrappers i intend to make more complicated adding all the companies not just RevMob. but no luck

i have tried the same code but with AppBrain it works like a charm but why revmob return NULL ??!! NOTE that i have already added the Dependson values on both

package appbrain.test.wrapper;
import com.appbrain.AppBrain;
import android.app.Activity;
import anywheresoftware.b4a.BA;
import anywheresoftware.b4a.BA.ActivityObject;
import anywheresoftware.b4a.BA.ShortName;


@ActivityObject
@ShortName("AppBrainTest")
@DependsOn(values={"google-play-services","revmob","appbrain"})
public class AppBrainextends Activity {
    private BA ba;
    private String eventName;

    public void AppBrainT(BA ba, String EventName )
    {

      AppBrain.init(ba.activity);
      AppBrain.getAds().showInterstitial(ba.activity);

    }
}

One more question if i wanted to pass the ba.activity as object so in b4a call it something like (ME) how can i do that ? to make sure it will never be NULL

Don't extend Activity in your library. It is possible but more complicated and in most cases it is not required.

ba.context is never null.
