Tip: Easy Interstitial Admob Ads.

  1. Open “Unreal Engine\4.7\Engine\Build\Android\Java\src\com\epicgames\ue4\GameActivity.java”
  • Import InterstitialAd.

import com.google.android.gms.ads.InterstitialAd;

  • Add global variables.

InterstitialAd interstitialAd;
AdRequest request;

  • Init ads in OnCreate function.

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

interstitialAd = new InterstitialAd(this);
interstitialAd.setAdUnitId("yourAdId");
interstitialAd.loadAd(request);

interstitialAd.setAdListener(new AdListener()
{
	@Override
	public void onAdFailedToLoad(int errorCode) 
	{
		//Toast.makeText(AndroidLauncher.this,
		//"ERROR: " + errorCode, Toast.LENGTH_SHORT).show();
	}
	@Override
	public void onAdLoaded() 
	{
		//Toast.makeText(AndroidLauncher.this,
		//"The interstitial is loaded", Toast.LENGTH_SHORT).show();
	}    

	@Override
	public void onAdClosed()
	{
		interstitialAd.loadAd(request);
	}
}); 


  • Find “public void AndroidThunkJava_ShowAdBanner(String AdMobAdUnitID, boolean bShowOnBottonOfScreen)” and comment out everything in this function and add your code.


if(_activity.interstitialAd != null)
{
	_activity.runOnUiThread(new Runnable()
	{
		@Override
		public void run()
		{
			if(_activity.interstitialAd.isLoaded() == true)
				_activity.interstitialAd.show();					
		}
	});

}


  • Comment out everything inside public void AndroidThunkJava_HideAdBanner() function.
  1. Use ShowAds function in blueprints, it will show fullscreen ad instead of a banner. Hide ads won’t work.
  2. Profit.

awesome thanks! Any idea on how to do the full screen video ads you see in a lot of the free android games?

@BPANDREW
You can choose what ads(text, image and video) you want to show while creating Interstitial Ad in Admob panel.

OOOH :slight_smile: thanks!

If I understand you right this solution does not allow to close the add?

The users’ reaction can be “priceless” :wink:

Interstitial Ad can be closed normally by clicking x. There is no need to have hide ad function.

And now it makes sense :slight_smile:

Now let’s wait and see if the 4.8 brings any improvements in this area. If not, I might actually test it out.

Many thanks for this! Would be great if epic provided this as a checkbox on the showads blueprint node though …

Epic needs to do a lot more with the adds for mobiles.

The current state of AdMob allows you to add only a single add unit per app. The whole system needs to be redesigned, to accept multiple ads IDs. Let’s see if 4.8 brings any changes, it’s supposed to be out next week.

Not to mention the support for other add networks than AdMob… In other words, it can only get better :wink:

please tell me how

this my gameactivity .

Where do I put it

Please, tell me how

up up up up up up up

Hi Kavin,

Please double check the instructions that ThePassenger has posted. Also, please refrain from bumping a thread more than once every four days. Thank you.

I know this is an older thread but I’ve got this working, Only issue is ill getting random freezes with the ad’s they will load a black screen and lock up the entire app. Has anyone experienced similar issues with this code?

I’m thinking about using this engine for a mobile game, but could someone first tell me if a similar thing that OP did with AdMob could be done with other ad-networks such as Chartboost? I imagine you could just add the necessary code to the game activity. Is there some reason that it wouldn’t be as simple as that?

Sorry for picking up such an old topic, but I’m trying to work it out on my own and still failing. I don’t know what am I doing wrong… Can you take a look at my GameActivity please? I thought I made everything correctly, but probably not…

Is there anything else I need to do to make it work? The problem is, that the node “Show Ad Banner” doesn’t do anything (and yes, I tried that on my android phone :D). What can be wrong? It’s more than a month I’m working on it, but now I’m really desperate, so I had to reply to this post.

Thank gonna try this :slight_smile:

seem that it doesnt work anymore with engine 4.8

Same here, show ad banner does anything, and i have the same code as you :frowning:

ok after some research on answerhub and this forum i got this working, but it sometime crash or fail to load the ads dont know why
