Introduction

Android is one of the most popular operating systems for mobile. In this article, I will show you how to show interstitial ads every 20 seconds in an Android application using Android Studio

Requirements

• Android Studio version 2.3.3
• Little bit XML and JAVA knowledge.
• Android Emulator (or) Android mobile
• Download link (Android Studio)

Steps to should be followed

Follow these steps to show interstitial ads every 20 seconds in an Android application. I have included the source code below.

Step 1

Open Android Studio and start a New Android Studio Project.

Step 2

You can choose your application name and choose the location where your project is to be stored. If you wish to use C++ for coding the project, mark the "Include C++ support", and click "Next" button.

Now, select the version of Android and select the target Android devices.

Step 3

Now, add the activity and click "Next" button.

Add Activity name and click "Finish".

Step 4

Go to activity_main.xml. This XML file contains the designing code for your Android app.

The XML code is given below.

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:app="http://schemas.android.com/apk/res-auto"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   tools:context="abu.interstitial_ad_every_20_seconds.MainActivity">

<TextView
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:text="Android Ad_Mob!"
   app:layout_constraintBottom_toBottomOf="parent"
   app:layout_constraintLeft_toLeftOf="parent"
   app:layout_constraintRight_toRightOf="parent"
   app:layout_constraintTop_toTopOf="parent" />

</android.support.constraint.ConstraintLayout>

Step 5

Go to (gradle scripts ⇒ build.gradle(moduleapp) and add the below code.

 

apply plugin: 'com.android.application'
android {
    compileSdkVersion 26
    buildToolsVersion "26.0.1"
    defaultConfig {
        applicationId "abu.interstitial_ad_every_20_seconds"
        minSdkVersion 19
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support',
        module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:26.+'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
    compile 'com.google.android.gms:play-services-ads:10.2.4'
}

Step 6

Go to Main Activity.java. This Java program is the backend language for Android app.

The java code is given below.

package abu.interstitial_ad_every_20_seconds;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.widget.Toast;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.InterstitialAd;
import java.util.concurrent.Executors;
import java.util.concurrent.ScheduledExecutorService;
import java.util.concurrent.TimeUnit;
public class MainActivity extends AppCompatActivity {
    private InterstitialAd mInterstitialAd;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        prepareAd();
        ScheduledExecutorService scheduler = Executors.newSingleThreadScheduledExecutor();
        scheduler.scheduleAtFixedRate(new Runnable() {
            public void run() {
                Log.i("hello", "world");
                runOnUiThread(new Runnable() {
                    public void run() {
                        if (mInterstitialAd.isLoaded()) {
                            mInterstitialAd.show();
                        } else {
                            Log.d("TAG", " Interstitial not loaded");
                        }
                        prepareAd();
                    }
                });
            }
        }, 20, 20, TimeUnit.SECONDS);
    }
    public void prepareAd() {
        mInterstitialAd = new InterstitialAd(this);
        mInterstitialAd.setAdUnitId("ca-app-pub-3940256099942544/1033173712");
        mInterstitialAd.loadAd(new AdRequest.Builder().build());
    }
}

Step 7

Now, go to the menu bar and click "make project" or press ctrl+f9 to debug the error.

Step 8

Then, click "Run" button or press shift+f10 to run the project. Choose the "virtual machine" and click OK.

Conclusion

We have successfully shown the interstitial ad every 20 seconds in an Android application using Android Studio.
