Example of AdMob integration in Raymob

README.md

AdMob Integration in the Raymob Repository

This gist serves as a guide on how to integrate AdMob into your Raymob project. For the actual Raymob repository, please refer to Raymob.

Please note that this gist focuses on the integration of interstitial ads, but the process is similar for other types of ads as well.

If you have any doubts, please consult the AdMob Android Quick Start Guide for further information.

To integrate AdMob into your project, follow these steps:

1. Add the following line to the end of the app/build.gradle file, under dependencies:

   implementation 'com.google.android.gms:play-services-ads:22.4.0'

2. Edit the existing NativeLoader.java and app/AndroidManifest.xml files in your project with the corresponding files provided in this gist.
3. Add the example file admob.h to your project.
4. Think about setting android.useAndroidX to true at the beginning of your gradle.properties; you'll need it for using the @NonNull annotations.

That's it! AdMob should now be successfully integrated into your Raymob repository.

NOTE: The AdMob identifiers provided in this example are meant for testing purposes and are provided by Google. Remember to replace them with your own identifiers.

Additional Information

If your application is intended to be available only on the Google Play Store, you can also use com.google.android.gms:play-services-ads-lite:22.4.0 instead of com.google.android.gms:play-services-ads:22.4.0.

This implementation will be much lighter and will help reduce the size of your application. For more information, please refer to this link: https://developers.google.com/admob/android/lite-sdk?hl=en

Hi, thank you for the code.

I seem to get an error on
jmethodID method = (*env)->GetMethodID(env, nativeLoaderClass, "isInterstitialAdLoaded", "()Z");
jmethodID method = (*env)->GetMethodID(env, nativeLoaderClass, "requestInterstitialAd", "()V");
jmethodID method = (*env)->GetMethodID(env, nativeLoaderClass, "showInterstitialAd", "()V");
The error comes back as 'nativeLoaderClass' is not a JVM object.

@bamfon Thank you for letting me know. Indeed, I just tried, and Android Studio is warning me about it too. However, since the compilation is successful, and the test ads are displaying correctly, I assume this must be related to an IDE issue.

The logic is exactly the same as that used in cpp/deps/raymob/features.c, and no messages appear in that file.

Hi @Bigfoot71 Thank you for this project.
But can you suggest me an approach to implement banner ads. The problem is that, Since there is no layout, how can I use a AdView.

I just got a solution and hope it helps some people. In this approach we use a popup window. you can find more about this groups.google.com & dynadream.com . its not a perfect solution so if you @Bigfoot71 have better solution , please do share.

My method that shows banner ad :

public void showAdPopup(){
    runOnUiThread(new Runnable() {
        @Override
        public void run() {
            popUp = new PopupWindow(_activity);
            popUp.setWidth(ViewGroup.LayoutParams.WRAP_CONTENT);
            popUp.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);
            popUp.setClippingEnabled(false);
            layout = new LinearLayout(_activity);
            mainLayout = new LinearLayout(_activity);
            layout.setPadding(-5,-5,-5,-5);
            ViewGroup.MarginLayoutParams params = new ViewGroup.MarginLayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT);
            params.setMargins(0,0,0,0);
            layout.setOrientation(LinearLayout.VERTICAL);
            layout.addView(mAdview,params);
            popUp.setContentView(layout);
            _activity.setContentView(mainLayout,params);

            AdRequest adRequest = new AdRequest.Builder().build();

            mAdview.loadAd(adRequest);
            popUp.showAtLocation(mainLayout,Gravity.BOTTOM,0,0);
            popUp.update();

        }
    });

}```

its not a perfect solution so if you @Bigfoot71 have better solution , please do share.

@SachinDas246 I have never used banners in my Android games, so I couldn't advise you on the best approach, but if it works without any issues for the application when displaying the pop-up, then your solution is likely the right one ;)

However, if you are writing your application in C++, you can see this alternative approach:
https://developers.google.com/admob/cpp/quick-start
https://developers.google.com/admob/cpp/banner

I am getting errors in android studio.
First I kept getting errors for symbols not found for three admob functions. I copied them into raymob.h and helpers.c.
now when I call ShowInterstitialAd from main.cpp I get NPE.
But I am only calling it after the ad is loaded.

if(IsInterstitialAdLoaded()) {
ShowInterstitialAd();
}

Thanks in advance

ok got it working but not sure why. Because it should have worked the way it was.

I moved the check for null inside the run function and now it works.

public void run() {
if(mInterstitialAd != null) {
mInterstitialAd.show(NativeLoader.this);
mInterstitialAd = null;
}
}

I am making a game using c++, the first error that I got was because of all the "(*env)->" present inside admob.h, so I changed all of those occurances them to "env->", other than that I followed the exact same instructions provided here. When i tested the interstitial ad feature, nothing was happening, so I followed the fix provided by @beardBall and now everything is working fine!

anyone got a full working .c example of ad showing.
