In order to earn money from the Android app or game, there are many ways such as in-App Purchases, Sponsorship, Advertisements, and many more. But there is another popular method to earn money from the Android app is by integrating an advertisement e.g known as Google AdMob. Google AdMob is designed with developers in mind, AdMob helps to earn more app revenue, deliver better user experience, and surface actionable insights all with automated tools that do the hard work for you.
Why Google Admob Network?
- Minimum Payout is $100
- Wide Range of Ad Formats
- Maximum Fill Rates
- High eCPM(Effective Cost Per Mille)
- Quality Ads
- Personalized Ads
Formats of Google AdMob
There are mainly four types of flexible, high-performing format available in Google AdMob
- Native: Ads that you design to fit the app, seamlessly
- Interstitial: Full-screen ads that capture attention and become part of the experience.
- Banner: Traditional formats in a variety of placements.
- Rewarded Video: An immersive, user-initiated video ad that rewards users for watching.
In this article let’s integrate Google Admob SDK to show Rewarded Video Ad in the Android app.
Rewarded Video:
- Rewarded Video ad is full-screen ads that cover the whole UI of the app. The eCPM (Effective Cost Per Mille) of Rewarded Video ads are relatively higher than banner and Interstitial ads and also leads to higher CTR(Click Through Rate) which results in more earning from your app.
- The user gets an in-App reward when they watch the Rewarded Video from start to end. This type of ad is mostly used in games and also can be used in the app.
Approach
Step 1: Creating a New Project
To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. Note that choose Java as language though we are going to implement this project in Java language.
Step 2: Before going to the coding section first do some pre-task
- Go to app -> res -> values -> colors.xml file and set the colors for the app.
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="colorPrimary">#0F9D58</color>
<color name="colorPrimaryDark">#0F9D58</color>
<color name="colorAccent">#05af9b</color>
</resources>
|
- Go to Gradle Scripts -> build.gradle (Module: app) section and import following dependencies and click the “sync now” on the above pop up.
implementation ‘com.google.android.gms:play-services-ads:19.3.0’
- Go to app -> manifests -> AndroidManifests.xml section and allow “Internet Permission“.
<uses-permission android:name=”android.permission.INTERNET”/>
- Go to app->manifests->AndroidManifest.xml section and add meta-data tag inside <application> tag.
<meta-data
android:name=”com.google.android.gms.ads.APPLICATION_ID”
android:value=”ca-app-pub-3940256099942544~3347511713″
/>
Step 3: Designing the UI
In the activity_main.xml add a Button so when the user will click the Button the Rewarded Video will be played on the screen.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<!-- Button to Show Rewarded Video Ad By Clicking it -->
<Button
android:id="@+id/showVideoBtn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_margin="8dp"
android:background="@color/colorPrimary"
android:padding="16dp"
android:text="Show Rewarded Video Ad "
android:textColor="#ffff"
android:textSize="20dp" />
</RelativeLayout>
|
Step 4: Working with MainActivity.java file
- Open the MainActivity.java file there within the class, first of all, create the object of the Button class.
// Creating a object of Button class
Button showVideoAdBtn;
- Now inside the onCreate() method, link those objects with their respective IDs that are given in activity_main.xml file.
// link those objects with their respective id’s that we have given in activity_main.xml file
showVideoAdBtn=(Button)findViewById(R.id.showVideoBtn);
- Now inside onCreate() method, initialize the Google Admob SDK
// initializing the Google Admob SDK
MobileAds.initialize(this);
- Create an object of RewardedVideoAd inside MainActivity.java class
// creating object of RewardedVideoAd
private RewardedVideoAd AdMobrewardedVideoAd;
- Create AdMob Rewarded Video Ad Id inside MainActivity.java class
// AdMob Rewarded Video Ad Id
private String AdId=”ca-app-pub-3940256099942544/5224354917″;
- Next create a private void loadRewardedVideoAd() method outside onCreate() method and define it.
void loadRewardedVideoAd()
{
// initializing RewardedVideoAd Object
// RewardedVideoAd Constructor Takes Context as its Argument
AdMobrewardedVideoAd = MobileAds.getRewardedVideoAdInstance(this);
// Loading Rewarded Video Ad
AdMobrewardedVideoAd.loadAd(AdId, new AdRequest.Builder().build());
}
- Call the loadRewardedVideoAd() inside oncreate() method after initializing the SDK.
Note: Replace “AdId” with your own app ad id to show real ads.
- Next create a void showRewardedVideoAd() method outside onCreate() method which we call later to show ad.
public void showRewardedVideoAd()
{
if(AdMobrewardedVideoAd.isLoaded())//Checking If Ad is Loaded or Not
{
// showing Video Ad
AdMobrewardedVideoAd.show();
}
else
{
// Loading Rewarded Video Ad
AdMobrewardedVideoAd.loadAd(AdId, new AdRequest.Builder().build());
}
}
- So the next thing is to call the showRewardedVideoAd() method. Now in oncreate() method create a ClickListener for the button and call showRewardedVideoAd().
// click listener to show Rewarded Video Ad
showVideoAdBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
showRewardedVideoAd();
}
});
- Now add RewardedVideoAdListener for Rewarded Video Ad, so that user will know the status of the ads.
- To add RewardedVideoAdListener open loadRewardedVideoAd() method and add the below code before AdMobrewardedVideoAd.loadAd(AdId, new AdRequest.Builder().build());
// Rewarded Video Ad Listener
AdMobrewardedVideoAd.setRewardedVideoAdListener(new RewardedVideoAdListener() {
@Override
public void onRewardedVideoAdLoaded() {
// Showing Toast Message
Toast.makeText(MainActivity.this, “onRewardedVideoAdLoaded”, Toast.LENGTH_SHORT).show();
}
@Override
public void onRewardedVideoAdOpened() {
// Showing Toast Message
Toast.makeText(MainActivity.this, “onRewardedVideoAdOpened”, Toast.LENGTH_SHORT).show();
}
@Override
public void onRewardedVideoStarted() {
// Showing Toast Message
Toast.makeText(MainActivity.this, “onRewardedVideoStarted”, Toast.LENGTH_SHORT).show();
}
@Override
public void onRewardedVideoAdClosed() {
// Showing Toast Message
Toast.makeText(MainActivity.this, “onRewardedVideoAdClosed”, Toast.LENGTH_SHORT).show();
}
@Override
public void onRewarded(RewardItem rewardItem) {
// Showing Toast Message
Toast.makeText(MainActivity.this, “onRewarded”, Toast.LENGTH_SHORT).show();
}
@Override
public void onRewardedVideoAdLeftApplication() {
// Showing Toast Message
Toast.makeText(MainActivity.this, “onRewardedVideoAdLeftApplication”, Toast.LENGTH_SHORT).show();
}
@Override
public void onRewardedVideoAdFailedToLoad(int i) {
// Showing Toast Message
Toast.makeText(MainActivity.this, “onRewardedVideoAdFailedToLoad”, Toast.LENGTH_SHORT).show();
}
@Override
public void onRewardedVideoCompleted() {
// Showing Toast Message
Toast.makeText(MainActivity.this, “onRewardedVideoCompleted”, Toast.LENGTH_SHORT).show();
}
});
- And inside RewardedVideoAdListener Override methods show a toast message so that users know the status of the ad. Below is the complete code for the MainActivity.Java file.
package org.geeksforgeeks.project;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {
// Creating a object of Button class

{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// link those objects with their respective id's

showVideoAdBtn
= (Button)findViewById(R.id.showVideoBtn);
// initializing the Google Admob SDK
MobileAds.initialize(this);
// loading Video Ad
loadRewardedVideoAd();
// click listener to show Rewarded Video Ad
showVideoAdBtn.setOnClickListener(

showRewardedVideoAd();
}
});
}
// creating RewardedVideoAd object

private String AdId
= "ca-app-pub-3940256099942544/5224354917";
void loadRewardedVideoAd()
{

AdMobrewardedVideoAd
= MobileAds.getRewardedVideoAdInstance(this);
// Rewarded Video Ad Listener
AdMobrewardedVideoAd.setRewardedVideoAdListener(
new RewardedVideoAdListener() {
@Override
public void onRewardedVideoAdLoaded()
{
// Showing Toast Message

"onRewardedVideoAdLoaded",
Toast.LENGTH_SHORT)
.show();
}
@Override

{
// Showing Toast Message

"onRewardedVideoAdClosed",
Toast.LENGTH_SHORT)
.show();
}
@Override
public void onRewarded(
RewardItem rewardItem)
{
// Showing Toast Message
Toast
.makeText(MainActivity.this,
"onRewarded",
Toast.LENGTH_SHORT)
.show();
}
@Override
public void
onRewardedVideoAdLeftApplication()
{
// Showing Toast Message
Toast
.makeText(
MainActivity.this,
"onRewardedVideoAdLeftApplication",
Toast.LENGTH_SHORT)
.show();
}
@Override
public void onRewardedVideoAdFailedToLoad(
int i)
{
// Showing Toast Message
Toast
.makeText(
MainActivity.this,
"onRewardedVideoAdFailedToLoad",
Toast.LENGTH_SHORT)
.show();
}
@Override
public void onRewardedVideoCompleted()
{
// Showing Toast Message
Toast
.makeText(
MainActivity.this,
"onRewardedVideoCompleted",
Toast.LENGTH_SHORT)
.show();
}
});
// Loading Rewarded Video Ad
AdMobrewardedVideoAd.loadAd(
AdId, new AdRequest.Builder().build());
}
public void showRewardedVideoAd()
{
// Checking If Ad is Loaded or Not
if (AdMobrewardedVideoAd.isLoaded()) {
// showing Video Ad
AdMobrewardedVideoAd.show();
}
else {
// Loading Rewarded Video Ad
AdMobrewardedVideoAd.loadAd(
AdId, new AdRequest.Builder().build());
}
}
