Cocos2d-x 2.x android 集成admob广告（三）banner＋interstitia

Chapter1:
1、创建一个 cocos2d-x项目 admob_combine
2、Eclipse :import->admob_combine->proj.android
3、Eclipse :Import ->libcocos2dx
选择 目录：……/cocos2d-x2.x/cocos2dx/platform/andorid/java，导入

Chapter2: 准备admob 测试帐号；
MY_INTERSTITIAL_ID = “ca-app-pub-3940256099942544/4411468910”；
MY_BANNER_ID = “ca-app-pub-3940256099942544/6300978111”;

Chapter3:把google-play-service.lib 加入项目android库。

add “google-play-services_lib ” to admob_combine 项目属性下的android 库。

Chapter4: 修改清单文件
1、androidManifest.xml内添加 admob广告支持。

!-- Include required permissions for Google Mobile Ads to run-->
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

<application>
        <!--This meta-data tag is required to use Google Play Services.-->
        <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

        <!--Include the AdActivity configChanges and theme. -->
        <activity android:name="com.google.android.gms.ads.AdActivity" android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" android:theme="@android:style/Theme.Translucent" />
    </application>

Chapter5 修改java文件
5.1、路径在src/com.walkiway.admob_combine下
5.2、admob_combine.java

package com.walkiway.admob_combine;

import org.cocos2dx.lib.Cocos2dxActivity;
import com.walkiway.admob_combine.AdmobPlugin;
import android.os.Bundle;
public class admob_combine extends Cocos2dxActivity {

   @Override
    protected void onCreate(final Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

           AdmobPlugin.setActivity(this);

        }

        @Override
        protected void onDestroy() {
             AdmobPlugin.destroy();

            super.onDestroy();
        }


        @Override
        protected void onResume() {
         AdmobPlugin.resume();

            super.onResume();
        }

        @Override
        protected void onPause() {
              AdmobPlugin.pause();

            super.onPause();
        }
    //add this line,if u using cocos2d-x2.x
        static {
            System.loadLibrary("cocos2dcpp");
        }   
}

Very Important: cocos2d-x 2.x下必须加这句，3.x下则不需要加
static {
System.loadLibrary("cocos2dcpp");
}

5.3、com.walkiway.admob_combine下新建class ->AdmobPlugin
编辑AdmobPlugin 代码如下：

package com.walkiway.admob_combine;

import android.app.Activity;
import android.util.Log;
import android.view.View;
import android.view.Gravity;

import android.graphics.Color;
import android.widget.LinearLayout;
import android.widget.RelativeLayout;


import com.google.android.gms.ads.AdListener;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.InterstitialAd;
import com.google.android.gms.ads.AdView;
import com.google.android.gms.ads.AdSize;

import org.cocos2dx.lib.Cocos2dxActivity;

public class AdmobPlugin {
    private static Cocos2dxActivity activity;
    private static final String TAG = "cocos2d";
    private static InterstitialAd interstitial;
    private static AdView adView;

    private final static String MY_INTERSTITIAL_ID = "ca-app-pub-3940256099942544/4411468910";
    private final static String MY_BANNER_ID = "ca-app-pub-3940256099942544/6300978111";

    public static void setActivity(Cocos2dxActivity act){
        activity = act;
    }

    public static void pause(){

          Log.i(TAG,"pause");

        if (adView != null) {
              Log.i(TAG,"adview.pause");
                 adView.pause();
               }

    }
    public static void destroy(){
          Log.i(TAG,"destroy");
        if (adView != null) {
              Log.i(TAG,"adview.destroy");
                 adView.destroy();

               }


    }
    public static void resume(){
          Log.i(TAG,"resume");
        if (adView != null) {
              Log.i(TAG,"adview.resume");
                 adView.resume();
               }

    }
    public static void showBanner(){
        activity.runOnUiThread(new Runnable() {

            @Override
            public void run() {
                if(adView == null){
                    try{

                            adView = new AdView(activity);
                            adView.setAdSize(AdSize.SMART_BANNER);
                            adView.setAdUnitId(MY_BANNER_ID);


                            RelativeLayout relativeLayout=new RelativeLayout(activity);

                            //TO access mFrameLayout in Cocos2d-V3.3 make it public!!
                            activity.mFrameLayout.addView( relativeLayout );

                        //Banner at the bottom 
                            RelativeLayout.LayoutParams adViewParams = new RelativeLayout.LayoutParams(
                            AdView.LayoutParams.WRAP_CONTENT,AdView.LayoutParams.WRAP_CONTENT);
                            adViewParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
                            relativeLayout.addView(adView,adViewParams);


                    }catch (Exception e) {
                        Log.e("AdmobPlugin",e.toString());
                    }
                }

                //Nexus7 device
                AdRequest request = new AdRequest.Builder().addTestDevice("E5FDDF2B808A6724F12238F571356547").build();
            // AdRequest request = new AdRequest.Builder().build();
                adView.loadAd(request);
                //Hack so that the banner is displayed at startup of the app??!!!!
                adView.setBackgroundColor(Color.BLACK); 
                adView.setBackgroundColor(0);  
                //---------------------------------------------------------------
                adView.setVisibility(View.VISIBLE);
            }
        });
    }

    public static void hideBanner(){
        activity.runOnUiThread(new Runnable() {

            @Override
            public void run() {
                if(adView != null){
                    adView.setVisibility(View.GONE);
                }
            }
        });
    }

    public static void showInterstitial(){
        activity.runOnUiThread(new Runnable() {

            @Override
            public void run() {
                interstitial = new InterstitialAd(activity);
                interstitial.setAdUnitId(MY_INTERSTITIAL_ID);
                //AdRequest adRequest = new AdRequest.Builder().build();
                //Nexus7 device
                AdRequest adRequest = new AdRequest.Builder().addTestDevice("E5FDDF2B808A6724F12238F571356547").build();
                interstitial.loadAd(adRequest);

                interstitial.setAdListener(new AdListener() {
                    @Override
                    public void onAdLoaded() {
                        activity.runOnUiThread(new Runnable() {

                            @Override
                            public void run() {
                                interstitial.show();
                            }
                        });
                    }
                });
            }
        });
    }
}

Very Important: 修改文件后，这句可能报错。
//TO access mFrameLayout in Cocos2d-V3.3 make it public!!
activity.mFrameLayout.addView( relativeLayout );

所以需要接下来这步。

5.4 修改在libcocos2dx/src/org.cocos2dx.lib/Cocos2dxActivity.java
protected static FrameLayout mFrameLayout;修改为

public static FrameLayout mFrameLayout;

Chapter6 修改CPP文件
在class下添加AdmobWrapper.h 和 AdmobWrapper.cpp

//AdmobWrapper.h


#ifndef ADMOB_WRAPPER_H_
#define ADMOB_WRAPPER_H_

class AdmobWrapper{

public:
    static AdmobWrapper * getInstance();

    static void setup();
    // show banner ad
    static void showBanner();
    // hide banner ad
    static void hideBanner();
    // show interstitial
    static void showInterstitial();

};

#endif /* defined(ADMOB_WRAPPER_H_) */

//AdmobWrapper.cpp



#include "AdmobWrapper.h"
#include <jni.h>
#include "platform/android/jni/JniHelper.h"


#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)


#define  JAVA_CLASS_NAME "com/walkiway/admob_combine/AdmobPlugin"

using namespace cocos2d;

static AdmobWrapper * s_Instance = NULL;

AdmobWrapper * AdmobWrapper::getInstance(){
    if(s_Instance == NULL){
        s_Instance = new AdmobWrapper();
    }

    return s_Instance;
}
void AdmobWrapper::setup(){
//void AdmobWrapper::setup(const char* bannerId,const char* lbAudioId){

    //Empty for Android 

    //CCLOG("AdmobWrapper::setup");
}


void AdmobWrapper::showBanner(){
    JniMethodInfo minfo;
    bool isHave = JniHelper::getStaticMethodInfo(minfo,JAVA_CLASS_NAME,"showBanner","()V");
    if(!isHave){
            //CCLOG("jni:openURL showBanner");
    }else{
        minfo.env->CallStaticVoidMethod(minfo.classID,minfo.methodID);
    }
}

void AdmobWrapper::hideBanner(){
    JniMethodInfo minfo;
    bool isHave = JniHelper::getStaticMethodInfo(minfo,"hideBanner","()V");
    if(!isHave){
            //CCLOG("jni:openURL hideBanner");
    }else{
        minfo.env->CallStaticVoidMethod(minfo.classID,minfo.methodID);
    }
}

void AdmobWrapper::showInterstitial(){
    JniMethodInfo minfo;
    bool isHave = JniHelper::getStaticMethodInfo(minfo,"showInterstitial","()V");
    if(!isHave){
            // CCLOG("jni:openURL showInter");
    }else{
        minfo.env->CallStaticVoidMethod(minfo.classID,minfo.methodID);
    }
}

#endif

Very Important: 为了cpp中直接用 类名::函数名() 引用，.h文件中定义为：static void showBanner();

//在需要调用admob的界面cpp加头文件
＃include "AdmobWrapper.h"

//调用interstitial类admob
AdmobWrapper::showInterstitial();

Chapter6: 编辑Android.mk 加入编译AdmobWrapper.cpp

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := cocos2dcpp_shared

LOCAL_MODULE_FILENAME := libcocos2dcpp

LOCAL_SRC_FILES := hellocpp/main.cpp 
                   ../../Classes/AppDelegate.cpp 
                   ../../Classes/HelloWorldScene.cpp
                   ../../Classes/AdmobWrapper.cpp

LOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes

LOCAL_WHOLE_STATIC_LIBRARIES := cocos2dx_static
LOCAL_WHOLE_STATIC_LIBRARIES += cocosdenshion_static
LOCAL_WHOLE_STATIC_LIBRARIES += box2d_static
LOCAL_WHOLE_STATIC_LIBRARIES += chipmunk_static
LOCAL_WHOLE_STATIC_LIBRARIES += cocos_extension_static

include $(BUILD_SHARED_LIBRARY)

$(call import-module,cocos2dx)
