and it's working well, , ads shown properly, wanna sure did , version of adomb proper , know if ready signed , uploaded play store :

here code in androidluncher:

public class androidlauncher extends androidapplication implements adhandler {     private static final string tag="androidlauncher";     protected adview adview;     private final int show_ads=1;     private final int hide_ads=0;     handler handler=new handler(){          @override         public void handlemessage(message msg) {             switch (msg.what){                 case show_ads:                     adview.setvisibility(view.visible);                     break;                 case hide_ads:                     adview.setvisibility(view.gone);                     break;             }          }     };      @override     protected void oncreate (bundle savedinstancestate) {         super.oncreate(savedinstancestate);         relativelayout layout=new relativelayout(this);         androidapplicationconfiguration config = new androidapplicationconfiguration();         view gameview= initializeforview(new fruits(this),config);         layout.addview(gameview);         adview=new adview(this);         adview.setadlistener(new adlistener() {             @override             public void onadloaded() {                  log.i(tag, "ad loaded");              }         });         adview.setadsize(adsize.smart_banner);         adview.setadunitid("ca-app-pub-7056408444444289676685175896");         adrequest.builder builder=new adrequest.builder();          relativelayout.layoutparams adparams=new relativelayout.layoutparams(relativelayout.layoutparams.wrap_content,relativelayout.layoutparams.wrap_content);         adview.loadad(builder.build());         layout.addview(adview, adparams);          setcontentview(layout);         //initialize(new fruits(), config);     }      @override     public void showads(boolean show) {         handler.sendemptymessage(show ?show_ads:hide_ads);     } } 

and manifest.xml file:

<uses-permission android:name="android.permission.write_external_storage"/>     <uses-permission android:name="android.permission.internet"/>     <uses-permission android:name="android.permission.access_network_state"/>      <uses-sdk android:minsdkversion="9" android:targetsdkversion="23" />      <application         android:allowbackup="true"         android:icon="@drawable/ic_launcher"         android:label="@string/app_name"         android:theme="@style/gdxtheme" >         <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version"/>         <activity             android:name="com.mygdx.game.androidlauncher"             android:label="@string/app_name"              android:screenorientation="landscape"             android:configchanges="keyboard|keyboardhidden|orientation|screensize">             <intent-filter>                 <action android:name="android.intent.action.main" />                 <category android:name="android.intent.category.launcher" />             </intent-filter>         </activity>         <activity android:name="com.google.android.gms.ads.adactivity"             android:configchanges="keyboard|keyboardhidden|orientation|screenlayout|uimode|screensize|smallestscreensize"/>     </application>  </manifest> 

and here build.grade:

ext {         appname = "fruits eater"         gdxversion = '1.7.2'         robovmversion = '1.12.0'         box2dlightsversion = '1.4'         ashleyversion = '1.7.0'         aiversion = '1.7.0'         admobversion='9.2.0'      }      dependencies {         compile project(":core")         compile "com.badlogicgames.gdx:gdx-backend-android:$gdxversion"         natives "com.badlogicgames.gdx:gdx-platform:$gdxversion:natives-armeabi"         natives "com.badlogicgames.gdx:gdx-platform:$gdxversion:natives-armeabi-v7a"         natives "com.badlogicgames.gdx:gdx-platform:$gdxversion:natives-x86"         compile "com.badlogicgames.gdx:gdx-box2d:$gdxversion"         natives "com.badlogicgames.gdx:gdx-box2d-platform:$gdxversion:natives-armeabi"         natives "com.badlogicgames.gdx:gdx-box2d-platform:$gdxversion:natives-armeabi-v7a"         natives "com.badlogicgames.gdx:gdx-box2d-platform:$gdxversion:natives-x86"         compile "com.google.android.gms:play-services-ads:$admobversion"     } 

and want know if need add google.service.json , or can publish game ads without need of google.service.json file

you don't need add file show ad in app.that file needed other more useful purposes...such in database,etc...
