Unity3d Android程序嵌入Admob广告条

原地址：http://dong2008hong.blog.163.com/blog/static/4696882720140441353482/

Seems like using a simple Android JAR files inside a Unity Android project is not such a simple thing to do. I finally managed to get AdMob working in an existing Unity Android game. For this example I was using Unity for Windows version 3.5.2 and the latest Android plugin for Eclipse.

Prerequisites

I assume that you have a working installation of Eclipse with the Android plugin on your computer. If not, please follow this tutorial to get your workspace ready: Download the Android SDK.

The Eclipse/Android part

  • Download the AdMob JAR file and register for an account if you haven’t done so already.
  • Create a new Android project. Make sure that the namespace (the package name) is identical to the namespace of your Unity Android project. You can set the namespace in Unity through Build Settings > Player Settings > Android tab > Other Settings > “Bundle Identifier”. In my example I am using my.android.game.
  • Copy the AdMob JAR file into the /libs folder of the project (you might have to create that folder manually).
  • Search inside of your Unity installation directory for the file classes.jar. Copy this file also into the /libs folder of your Eclipse project.
  • To test if the ads are being displayed we first create a regular Android class calledAdMobActivity.java. The content of this class looks like this: 

    先决条件
    我假设你已经装好了Eclipse的Android插件，在您的计算机上安装。如果没有，请按照本教程，让您的工作区准备：下载Android SDK。
  • 在Eclipse/ Android的部分
    下载的AdMob的JAR文件，并注册一个帐号，如果你还没有这样做的话。
    创建一个新的Android项目。请确保您的Unity Android项目的命名空间的命名空间（包名）是相同的。您可以设置统一的命名空间中，通过Build Settings > Player Settings > Android tab > Other Settings > “Bundle Identifier”。
  • 在我的例子中，我使用的my.android.game。
    AdMob的JAR文件复制到/libs文件夹中的项目（您可能需要手动创建该文件夹）。
    搜索内统一安装目录中的文件classes.jar的。把这个文件复制到/libs文件夹的Eclipse项目。
    如果要测试所显示的广告，我们首先创建一个普通的Android称为AdMobActivity.java的类。这一类的内容看起来像这样：
  • 以下是代码部分：
  • package my.android.game;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Gravity;
import android.view.ViewGroup.LayoutParams;
import android.widget.LinearLayout;
import com.admob.android.ads.AdManager;
import com.admob.android.ads.AdView;
import com.admob.android.ads.SimpleAdListener;
public class AdMobActivity extends Activity
{
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		Log.i("AdMobTest", "onCreate");
		// super (UnityPlayerActivity) will use setContentView() ...
		super.onCreate(savedInstanceState);
		// ... so instead of using setContentView(), we call addContentView()
		// from setupAds()
		setupAds();
		// Add test devices (check the logcat for the ID string of your
		// device..)
		// If you want to display test-ads uncomment this line of code and replace YOUR_DEVICE_ID with your device ID which AdMob displays in your logfile.
		AdManager.setTestDevices( new String[] { "YOUR_DEVICE_ID" } );
	}
	private void setupAds() {
		// And this is the same, but done programmatically
		LinearLayout layout = new LinearLayout(this);
		layout.setOrientation(LinearLayout.VERTICAL);
		layout.setGravity(Gravity.BOTTOM);
		addContentView(layout, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
		AdView adView = new AdView(this);
		layout.addView(adView, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
		adView.setBackgroundColor(0xff000000);
		adView.setPrimaryTextColor(0xffffffff);
		adView.setSecondaryTextColor(0xffcccccc);
		adView.setKeywords("Android game");
		adView.setRequestInterval(15);
		// add listener for easier debugging
		adView.setAdListener(new SimpleAdListener() {
			@Override
			public void onFailedToReceiveAd(com.admob.android.ads.AdView adView) {
				Log.d("AdListener", "onFailedToReceiveAd: " + adView.toString());
				super.onFailedToReceiveAd(adView);
			}
			@Override
			public void onFailedToReceiveRefreshedAd(com.admob.android.ads.AdView adView) {
				Log.d("AdListener", "onFailedToReceiveRefreshedAd: " + adView.toString());
				super.onFailedToReceiveRefreshedAd(adView);
			}
			@Override
			public void onReceiveAd(com.admob.android.ads.AdView adView) {
				Log.d("AdListener", "onReceiveAd: " + adView.toString());
				super.onReceiveAd(adView);
			}
			@Override
			public void onReceiveRefreshedAd(com.admob.android.ads.AdView adView) {
				Log.d("AdListener", "onReceiveRefreshedAd: " + adView.toString());
				super.onReceiveRefreshedAd(adView);
			}
		});
		adView.requestFreshAd();
	}
}
  • Update the AndroidManifest.xml file in your Eclipse project. It should look like this: 
    更新AndroidManifest.xml 文件，像以下这样
  • <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="my.android.game"
    android:versionCode="1"
    android:versionName="1.0" >
    <uses-sdk android:minSdkVersion="7" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name="my.android.game.AdMobActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
 		<!-- The application's publisher ID assigned by AdMob -->
        <meta-data android:value="YOUR_PUBLISHER_ID" android:name="ADMOB_PUBLISHER_ID" />
        <!-- AdMobActivity definition -->
        <activity android:name="com.admob.android.ads.AdMobActivity"
                  android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
                  android:configChanges="orientation|keyboard|keyboardHidden" />        
    </application>
</manifest>

    Make sure to replace YOUR_PUBLISHER_ID with your actual AdMob publisher ID.

  • 将其中的YOUR_PUBLISHER_ID 替换成你的Admob发布商ID

  • Build and run the app on your Android phone and you should see the AdMob banner being displayed. If you don’t please refer to the AdMob tutorials how to implement the banner into the Android app. Once this works continue with this tutorial.
  • 如果你没看到Admob的广告条，请按照Admob的官网教程去查看你的Admob配置步骤是否正确。
  • Create a class called AdMobUnityActivity.java. You can use your previously created AdMobActivity.java class as a base. The class will look like this: 
    package my.android.game;
import android.os.Bundle;
import android.util.Log;
import android.view.Gravity;
import android.view.ViewGroup.LayoutParams;
import android.widget.LinearLayout;
import com.admob.android.ads.AdManager;
import com.admob.android.ads.AdView;
import com.admob.android.ads.SimpleAdListener;
import com.unity3d.player.UnityPlayer;
import com.unity3d.player.UnityPlayerActivity;
public class AdMobUnityActivity extends UnityPlayerActivity {
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
	}
	public static void setupAdsStatic() {
		UnityPlayer.currentActivity.runOnUiThread(new Runnable() {
			public void run() {
				// If you want to display test-ads uncomment this line of code and replace YOUR_DEVICE_ID with your device ID which AdMob displays in your logfile.
				// AdManager.setTestDevices(new String[] { "YOUR_DEVICE_ID" });
				// And this is the same, but done programmatically
				LinearLayout layout = new LinearLayout(UnityPlayer.currentActivity.getApplicationContext());
				layout.setOrientation(LinearLayout.VERTICAL);
				
				// SET HERE IF YOU WANT THE BANNER TO BE DISPLAYED AT THE TOP OR BOTTOM OF THE SCREEN
				layout.setGravity(Gravity.BOTTOM);
				UnityPlayer.currentActivity.addContentView(layout, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
				AdView adView = new AdView(UnityPlayer.currentActivity);
				layout.addView(adView, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
				adView.setBackgroundColor(0xff000000);
				adView.setPrimaryTextColor(0xffffffff);
				adView.setSecondaryTextColor(0xffcccccc);
				
				// SET SOME KEYWORDS FOR THE ADS TO DISPLAY
				adView.setKeywords("Android game");
				adView.setRequestInterval(15);
				// add listener for easier debugging
				adView.setAdListener(new SimpleAdListener() {
					@Override
					public void onFailedToReceiveAd(com.admob.android.ads.AdView adView) {
						Log.d("AdListener", "onFailedToReceiveAd: " + adView.toString());
						super.onFailedToReceiveAd(adView);
					}
					@Override
					public void onFailedToReceiveRefreshedAd(com.admob.android.ads.AdView adView) {
						Log.d("AdListener", "onFailedToReceiveRefreshedAd: " + adView.toString());
						super.onFailedToReceiveRefreshedAd(adView);
					}
					@Override
					public void onReceiveAd(com.admob.android.ads.AdView adView) {
						Log.d("AdListener", "onReceiveAd: " + adView.toString());
						super.onReceiveAd(adView);
					}
					@Override
					public void onReceiveRefreshedAd(com.admob.android.ads.AdView adView) {
						Log.d("AdListener", "onReceiveRefreshedAd: " + adView.toString());
						super.onReceiveRefreshedAd(adView);
					}
				});
				adView.requestFreshAd();
			}
		});
	}
}

    The class now extends UnityPlayerActivity instead of Activity. Also we created the static function setupAdsStatic() and left the onCreate() function nearly empty. Also we have to wrap the whole content of this function into

    这个类继承了UnityPlayerActivity 。我们将创建一个静态方法setupAdsStatic().
  • UnityPlayer.currentActivity.runOnUiThread(new Runnable() {
	public void run() {
		...
	}
}

    otherwise we would get an error or a crash in Unity when we call the function. Also some content inside that function is a bit different in order to make it work with Unity.

  • Not entirely sure if the following step is needed but just do it anyways: Add this line to the AndroidManifest.xml file inside the “application” tags: 
    重新配置AndroidManifest.xml 文件，增加一个activity标签如下：
  • <activity android:name="my.android.game.AdMobUnityActivity"></activity>
  • Export the project to a JAR file. Click the right mouse button in the package explorer in Eclipse on your project and choose Export… > Java/JAR File > (standard settings) enter a name for the JAR file > Finish

Now you’re done with the part in Eclipse. Now we have to add that plugin into Unity 3D.

The Unity part

  • Copy the created JAR file inside your Unity Android project into the folder/Plugins/Android/
  • Also copy the AdMob JAR file into the same folder /Plugins/Android/
  • Complete the AndroidManifest.xml file inside your Unity Android project located at:AssetsPluginsAndroidAndroidManifest.xml. The content of this file will look like this: 
    <?xml version="1.0" encoding="utf-8"?>
<manifest
    xmlns:android="http://schemas.android.com/apk/res/android"
    package="my.android.game"
	android:installLocation="preferExternal"
    android:versionCode="1"
    android:versionName="1.0">
	
    <supports-screens
        android:smallScreens="true"
        android:normalScreens="true"
        android:largeScreens="true"
        android:xlargeScreens="true"
        android:anyDensity="true"/>
    <application
		android:icon="@drawable/app_icon"
        android:label="@string/app_name"
        android:debuggable="true">
						
        <activity android:name="com.unity3d.player.UnityPlayerProxyActivity"
                  android:label="@string/app_name"
                  android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">
        </activity>
        <activity android:name="com.unity3d.player.UnityPlayerActivity"
                  android:label="@string/app_name"
                  android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">
        </activity>
        <activity android:name="com.unity3d.player.UnityPlayerNativeActivity"
                  android:label="@string/app_name"
                  android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">
            <meta-data android:name="android.app.lib_name" android:value="unity" />
            <meta-data android:name="unityplayer.ForwardNativeEventsToDalvik" android:value="true" />
        </activity>
        <activity android:name="com.unity3d.player.VideoPlayer"
                  android:label="@string/app_name"
                  android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">
        </activity>	
		<activity android:name="my.android.game.AdMobUnityActivity"></activity>	
		
		<!-- The application's publisher ID assigned by AdMob -->
        <meta-data android:value="YOUR_PUBLISHER_ID" android:name="ADMOB_PUBLISHER_ID" />
        <!-- AdMobActivity definition -->
        <activity android:name="com.admob.android.ads.AdMobActivity"
                  android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
                  android:configChanges="orientation|keyboard|keyboardHidden" />    
    </application>
	<!-- PERMISSIONS -->
	<uses-permission android:name="android.permission.INTERNET"></uses-permission>
	<uses-permission android:name="android.permission.GET_TASKS"></uses-permission>
	<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
	<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
	<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
	
</manifest>

    Make sure the package name (namespace) is correct and identical to the namespace in your Eclipse project. Also change the YOUR_PUBLISHER_ID value with the value of your actual AdMob publisher ID. Note that if you are already using other Android plugins this manifest file might be looking a bit different than in my example.

  • To finally display the ad banner inside a scene of your Unity Android game create or modify a C# script with the following content: 
    using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System.Runtime.InteropServices;
using System;
public class Startup : MonoBehaviour
{
	public static AndroidJavaClass adMobJavaClass;
	
	void Start() {
		
		if( Application.platform == RuntimePlatform.Android ) {
			// Initialize AdMob
			adMobJavaClass = new AndroidJavaClass("my.android.game.AdMobUnityActivity");
			
			// AdMob display banner
			adMobJavaClass.CallStatic("setupAdsStatic");
		}
		
	}
}
