Why am I getting ObjCClassNotFoundException: GADInterstitial in RoboVM?

Question

I am implementing admob in my iOS module using this guide.

I have a view controller where my interstitial ads are initialized like this

@CustomClass
public class ViewController extends UIViewController implements ActionResolver {

private GADInterstitial interstitial;

private static final String AD_UNIT_ID = "ca-app-pub-XXXXXXXXXXXXXXXX-XXXXXXXXXX";

public ViewController() {
    viewDidLoad();
}

@Override
public void viewDidLoad() {
    super.viewDidLoad();

    interstitial = createAndLoadInterstitial();
}

private GADInterstitial createAndLoadInterstitial() {
    //Ad Unit ID of your interstital, from adMob account.
    GADInterstitial interstitial = new GADInterstitial(AD_UNIT_ID);
    System.out.println("Add unit ID is " + AD_UNIT_ID);
    interstitial.setDelegate(new GADInterstitialDelegateAdapter() {
        @Override
        public void didDismissScreen(GADInterstitial ad) {
            ViewController.this.interstitial = createAndLoadInterstitial();
        }
    });
    interstitial.loadRequest(createRequest());
    return interstitial;
}

private GADRequest createRequest() {
    GADRequest request = new GADRequest();
    // To test on your devices, add their UDIDs here:
    request.setTestDevices(Arrays.asList(GADRequest.getSimulatorID()));
    return request;
}

@IBAction
public void showInterstitialAd() {
    if (interstitial.isReady()) {
        interstitial.present(UIApplication.getSharedApplication().getKeyWindow().getRootViewController());
        System.out.println("Interstitial is loaded.");
    } else {
        interstitial.loadRequest(createRequest());
        System.out.println("Interstitial not ready!");
    }
}

}

My implementation is similar to this guide also.

When I run my app on the simulator I get the following exception.

I have imported the admob framework on my ios build.gradle. I have also tried moving it to ios module in main build.gradle though this doesnt change anything. How can I fix this error? My class is being imported correctly and I am using project.ext.robopodsVersion = "1.14.0" on my app build.gradle.

@SAKIROGLUKoray considering robovm is no longer supported, I dont think this bug will be solved. — Zack, Jul 30 '16 at 12:39

Fortunately some people forked the project and I have found a working solution :)

The fork : https://github.com/MobiDevelop/robovm-robopods

I did the following.

Gradle:

Build script dependency

dependencies {
    ...
    classpath 'com.mobidevelop.robovm:robovm-gradle-plugin:2.2.0-SNAPSHOT'
}

IOS Project dependencies:

...
compile "com.mobidevelop.robovm:robopods-google-mobile-ads-parent:2.2.0-SNAPSHOT"
compile "com.mobidevelop.robovm:robopods-google-mobile-ads-ios:2.2.0-SNAPSHOT"
compile "com.mobidevelop.robovm:robovm-rt:2.2.0-SNAPSHOT"
compile "com.mobidevelop.robovm:robovm-cocoatouch:2.2.0-SNAPSHOT"

Download SDK from here

Copy the GoogleMobileAds.framework folder in ios/libs

Modify the robovm.xml file (I went completely overkill on the frameworks list but I was tired of compilation error, if you find the ones that are not necessary, feel free to let me know):

<config>
    ...
    <frameworkPaths>
        <path>libs</path>
    </frameworkPaths>
    <frameworks>
        <framework>UIKit</framework>
        <framework>OpenGLES</framework>
        <framework>QuartzCore</framework>
        <framework>CoreGraphics</framework>
        <framework>OpenAL</framework>
        <framework>AudioToolbox</framework>
        <framework>AVFoundation</framework>
        <framework>AdSupport</framework>
        <framework>AudioToolbox</framework>
        <framework>CoreMedia</framework>
        <framework>CoreMotion</framework>
        <framework>CoreVideo</framework>
        <framework>CoreTelephony</framework>
        <framework>CoreBluetooth</framework>
        <framework>SafariServices</framework>
        <framework>EventKit</framework>
        <framework>EventKitUI</framework>
        <framework>MediaPlayer</framework>
        <framework>MessageUI</framework>
        <framework>StoreKit</framework>
        <framework>SystemConfiguration</framework>
        <framework>GoogleMobileAds</framework>
        <framework>VideoToolbox</framework>
        <framework>GLKit</framework>
    </frameworks>
</config>

And this works (for me)
