[Cocos Creator][Android] Cách tích hợp AdMob Banner vào Cocos

Bài này mình sẽ hướng dẫn cách tích hợp AdMob Banner vào Cocos Creator. Sau khi build bằng Cocos Creator, mở dự án proj.android-studio bằng Android Studio rồi thực hiện các thay dổi sau:

1. proj.android-studio/build.gradle

buildscript {
    repositories {
        google()
        jcenter()
		// Google AdMob
        mavenCentral()
    }
...

allprojects {
    repositories {
        google()
		// Google AdMob
		mavenCentral()
...

2. proj.android-studio/gradle.properties

PROP_MIN_SDK_VERSION=19
...
android.useAndroidX=true
org.gradle.daemon=true
org.gradle.configureondemand=true
org.gradle.jvmargs=-Xmx4g -XX:MaxPermSize=2048m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

3. proj.android-studio/app/AndroidManifest.xml

<application
...
    <!-- Sample AdMob app ID: ca-app-pub-3940256099942544~3347511713 -->
    <meta-data
        android:name="com.google.android.gms.ads.APPLICATION_ID"
        android:value="ca-app-pub-3940256099942544~3347511713"/>

4. proj.android-studio/app/build.gradle

dependencies {
...
	// adMob
    implementation 'com.google.android.gms:play-services-ads:21.3.0'

5. proj.android-studio\app\src\org\cocos2dx\javascript\AppActivity.java

...
// Admob
import com.google.android.gms.ads.MobileAds;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;
import com.google.android.gms.ads.AdSize;
import android.widget.RelativeLayout;

public class AppActivity extends Cocos2dxActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
...
        // Admob
        MobileAds.initialize(this, new OnInitializationCompleteListener() {
            @Override
            public void onInitializationComplete(InitializationStatus initializationStatus) {
            }
        });

        AdView adView = new AdView(this);

        RelativeLayout relativeLayout = new RelativeLayout(this);
        mFrameLayout.addView(relativeLayout);

        RelativeLayout.LayoutParams adViewParams = new RelativeLayout.LayoutParams(
                AdView.LayoutParams.WRAP_CONTENT,
                AdView.LayoutParams.WRAP_CONTENT);

        adViewParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
        adViewParams.addRule(RelativeLayout.CENTER_HORIZONTAL);
        relativeLayout.addView(adView, adViewParams);

        adView.setAdSize(AdSize.BANNER);

        // Test adunit
        adView.setAdUnitId("ca-app-pub-3940256099942544/6300978111");

        AdRequest adRequest = new AdRequest.Builder().build();
        adView.loadAd(adRequest);
