Android Tutorial AdMob Mediation (with InMobi)

AdMob supports ads mediation. This means that the ad can come from different ad networks and not just from Google AdMob network.

It can improve the fill rate and the revenue earned.

You should first start with the standard FirebaseAdMob implementation: https://www.b4x.com/android/forum/threads/67710/#content
Once it works you can continue with adding support for more networks.

Overall it is quite simple to add this feature. The most important tips:

1. Monitor the unfiltered logs (you must use USB debug mode for this) to see any errors.
2. It takes several hours for changes to be applied.

The steps required to add support for a network that is supported by AdMob (list of supported networks):
1. Register with the network.
2. Follow their specific instructions. You will need to add some declarations with the manifest editor.
In the case of InMobi: https://support.inmobi.com/monetize/mediation-guidelines/admob/android-admob-guidelines

AddApplicationText(
<activity
android:name="com.inmobi.rendering.InMobiAdActivity"
android:configChanges="keyboardHidden|orientation|keyboard|smallestScreenSize|screenSize"
android:hardwareAccelerated="true" />
)

Check the generated Objects\AndroidManifest.xml file if you are not sure whether you added it correctly or not.

3. You will need to download the network SDK and adapter jar, copy them to the additional libraries folder and add a reference to those libraries in your project. For example:

#AdditionalJar: libadapterinmobi
#AdditionalJar: InMobi-5.3.1

4. The additional source should be listed in AdMob under the unit:

That's all. The code itself is exactly the same.

I have been testing this again...

I notice that the APK is about the same size as the admob only one.

while the inmodi jar is 600Kb shouldn't it grow by 600K then?

when I look at the apk contents the only (non-binary) difference I see is that the admobi mediation one has a src.zip in the root with an admob wrapper file but nothing mentioned about inmobi either.


Edit: I notice that the classes.dex file is 900K bigger but due to the zipping the difference is only 50Kb or so.

still didn't see an ad like in Erel's first post tho.

 

[sorex]

Same here.. still pending

check your login settings, overhere the password was gone.

click the cog/wheel next to the questionmark at the top right of the admob site
then click ad network optimization setting
edit the inmobi one
fill in the password again if it's gone.

overhere when I look again the password is there but when I look at other pages and then again at the account the password is gone again.

I contact admob about this and asked if it is normal behaviour or a password trashing bug somewhere. I'll let you know when I get an answer.

@Erel,

that adapter jar is that also working with the v6.0 sdk jar?

that's what I'm using as that was the latest.

 

[Erel]

Should work. Make sure to check the unfiltered logs for any errors.

 

[sorex]

the problem is that admob always spits out own ads for me so it's hard to check.

I created another placement id for an app that has almost no users so I can force inmobi to be the one that pulls ads with your $10 trick.

Need to wait a few hours before the mediation becomes active and then I can check the logs as you mentioned.

 

[Erel]

You can also test it with the rewarded video ads.

 

[sorex]

does mediation rely on google play services while firebase admob ads don't?

I see the mediation request in admob but with 0 impression fill.

It was also an ad that shows up regulary via admob.

the log doesn't mention a real error besides the play stuff

[sorex]

Erel,

can you upload that 5.3.1.jar somewhere plz?

I can't find it anywhere on ze mighty net.

 

[Erel]

Why not use their latest version (6.0.1)? Make sure to test it on a real device.

 

[sorex]

well, I'm not sure that 6.0 or 6.0.1 is working right.

I'm not getting any ads from them on geny or real device.

 

[Erel]

I think that you are correct. Looks like the latest version of their adapter is broken. Use the attached libs.

 

[sorex]

thanks! I will give that a try.

I was just testing with the 6.0.1 and that one spits out errors but still goes on with the lower priority admob ad.

[sorex]

with their 6.0.1 adapter I can see that it reads in my app id, placement id etc from admob so we're making progress.

to be continued...

 

[Erel]

Looks like something is misconfigured on your side.

This is how it looks in AdMob console here:

Start with the rewarded videos. I tested them today and they work.

 

[sorex]

I have added that aswell and I see those values passing by now in the logs which didn't happen before.

but now it gives a "Context not an Activity. Returning error!" error

 

[Erel]

but now it gives a "Context not an Activity. Returning error!" error

I saw this error with the newer version of the adapter. Are you sure that you are using the one from the zip file I posted?

 

[sorex]

I tried several. this error occurs with the new 6.0.1 one. I will double check this again.

I followed your rewarded ad tutorial but that one returns a no add fill in the log. my own rewarded ads id ain't not active yet.

 

[sorex]

alright, now I got a (non rewarded) video ad displayed probably coming from inmobi.

with the 5.3.1 jars

 

[sorex]

just got a reply from those people but it's like chinese to me ...

Hi There,

InMobi Android SDK 600 requires Activity type Object to instantiate InMobi Interstitial ad. So when you must be instantiating AdMob InterstitialAd() object pass object of type Activity as parameter, instead of Context type.

Thanks,
Team InMobi
