Android admob app crash..

I am following the next tutorial in a empty scene..

https://developers.google.com/admob/android/games#unity

When I deploy the proyect to an android device it crash.. I try with a Nexus 5, 6, 7 emulator device.
In the unity editor works fine but it doesn't show any ads..

Unity3d version 5.2.3f1
Google Play Services Rev. 28
Google Mobile Ads Unity Plugin v2.3.1


I try differents androidmanifest files..

Adding

<activityandroid:name="com.unity3d.player.UnityPlayerNativeActivity"
android:label="@String/app_name">
<intent-filter>
<actionandroid:name="android.intent.action.MAIN"/>
<categoryandroid:name="android.intent.category.LAUNCHER"/>
</intent-filter>
<meta-dataandroid:name="unityplayer.UnityActivity"android:value="true"/>
<meta-dataandroid:name="unityplayer.ForwardNativeEventsToDalvik"
android:value="true"/></activity>

or just adding this sentece to the main activity

<meta-dataandroid:name="unityplayer.ForwardNativeEventsToDalvik"
android:value="true"/>

or adding nothing. Nothings work... This is my code.

usingGoogleMobileAds.Api;

private void RequestBanner(){
#if UNITY_ANDROID
string adUnitId ="ca-app-pub-xxxxxxxxxxxxxxxxxxxxxx";
#elif UNITY_IPHONE
string adUnitId ="INSERT_IOS_BANNER_AD_UNIT_ID_HERE";
#else
string adUnitId ="ca-app-pub-xxxxxxxxxxxxxxxxxxxxxx";
#endif

// Create a 320x50 banner at the top of the screen.
BannerView bannerView =newBannerView(adUnitId,AdSize.Banner,AdPosition.Top);
// Create an empty ad request.
AdRequest request =newAdRequest.Builder().Build();
// Load the banner with the request.
bannerView.LoadAd(request);}

The app crash in thes last line.. bannerView.LoadAd(request);

The crash log..

I don't know what to do..
Sorry for my english
Thanks in advance!!

 

At least!!! I find the solution, just in case someone happend the same..

In the assets folder "assets/Plugins/Android/"

You have to copy the files

"\AppData\Local\Android\sdk\extras\android\support\v4\"

Admob has a compatibility problem. Need to include dependencies to android support libraries.

 

That did not solve the problem for me, the game still crashed.

 

BIG THX 1WeekGames

 

check this https://github.com/unity-plugins/Unity-Admob

 

This tutorial solve the problem for me. After integrating admob 2019 my app crashed but not anymore.

 

Which build system did you use? Internal or Gradle?

 

Internal . I am not able to build any app with gradle in unity till now.
