Cocos2d-x 2.x android下集成admob广告(一）顶部banner

Chapter1:
1、创建一个 cocos2d-x项目 admob_test
2、用Eclipse import-> admob_testproj.android
3、Import ->libcocos2dx
选择 目录：……/cocos2d-x2.x/cocos2dx/platform/andorid/java，导入；
4、编译CPP files
4.1选择proj.andorid目录 ，启动终端；
4.2设置ANDROID_SDK_ROOT 和 NDK_ROOT
export ANDROID_SDK_ROOT=”/Users/SamMa/Desktop/AndroidStudio/sdk”
export NDK_ROOT=”/Users/SamMa/Desktop/AndroidStudio/android-ndk-r10d”
4.3 编译 build_native.sh

5、用Eclipse真机测试
选择admob_test 项目右键-> Build Configruation->Target 选择每次提示选择调试设备
选择admob_test 项目右键-> Run as Android App

Chapter2:admob Account
1、申请 admob account
2、创建APP，准备banner 广告，插屏广告；

Chapter3: Implementing AdMob in Android cocos2d-x 2.x based game
1、下载并安装 “Google Play Services” SDK
Eclipse 选择Android SDK Manager 下载 Google Play Services
2、Eclipse Import :google_play_services_lib
路径：/Users/SamMa/Desktop/AndroidStudio/sdk/extras/google/google_play_services/libproject/
3、在项目代码中引用google_play_services_lib


4、尽量使 all projects (admobTest,google-play-services_lib and libcocos2dx) have the same build target (但 Android 4.42 、5.0.1、 5.0.1 在此例真机运行OK).
5、修改清单文件
参考：https://developers.google.com/admob/android/eclipse
5.1 AndroidManifest.xml：

<!-- 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>

需要完成以下三项更改：

为 INTERNET 和 ACCESS_NETWORK_STATE 添加两个 <uses-permission> 标记。INTERNET 的标记是必需的，用于访问互联网以发送广告请求。 ACCESS_NETWORK_STATE 是可选的，用于在发出广告请求前检查是否有可用的互联网连接。

添加一个引用 Google Play 服务版本的 <meta-data> 标记。这会让 Android 知道您的应用希望使用哪个版本的服务。

添加具有 configChanges 和 theme 属性的 <activity> 元素。当横幅广告被点击或展示插页式广告时，SDK 会使用此活动，而且与其他活动一样，必须在展示之前在清单中声明此活动。

5.2 为应用指定广告单元 ID －修改BannerExample/res/values/strings.xml

<string name="banner_ad_unit_id">ca-app-pub-3940256099942544/6300978111</string>

上面提供的广告单元 ID 仅用于测试，由Google 提供。

6、 Editing Java file
Edit admobtest->src->com->walkiway->admob_test->admob_test.java

应用程序正式发布时，此处应根据admob 账号 APP 里的广告ID 进行修改。

7、 Editing CPP file:
Create a new file “AdmobHelper.h” in “admobTestClasses”

/* Copyright (c) 2014 Mudafar GPLv3 */


#ifndef __ADMOB_HELPER_H_
#define __ADMOB_HELPER_H_

class AdmobHelper {
public:
    static void hideAd();
    static void showAd();
    static bool isAdShowing;

};


#endif // __ADMOB_HELPER_H_

Create a new file “AdmobHelper.cpp” in “admobTestClasses”

/* Copyright (c) 2014 Mudafar GPLv3 */


#include "AdmobHelper.h"
#include "cocos2d.h"


bool AdmobHelper::isAdShowing = true;

#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)

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


const char* AppActivityClassName = "com/walkiway/admob_test/admob_test";

void AdmobHelper::hideAd()
{
    cocos2d::JniMethodInfo t;
    if (cocos2d::JniHelper::getStaticMethodInfo(t,AppActivityClassName,"hideAd","()V"))
    {

        t.env->CallStaticVoidMethod(t.classID,t.methodID);
        t.env->DeleteLocalRef(t.classID);
        isAdShowing = false;
    }
}



void AdmobHelper::showAd()
{

    cocos2d::JniMethodInfo t;
    if (cocos2d::JniHelper::getStaticMethodInfo(t,"showAd",t.methodID);
        t.env->DeleteLocalRef(t.classID);
        isAdShowing = true;
    }

}


#else


void AdmobHelper::hideAd()
{
    CCLOG("hideAd() called");
    isAdShowing = false;
    return; //nothing
}


void AdmobHelper::showAd()
{
    CCLOG("showAd() called");
    isAdShowing = true;
    return; //nothing;

}

#endif

Very Important: const char* AppActivityClassName = "com/walkiway/admob_test/admob_test";
proj.andorid/src目录下路径，最后的.java后缀不要写。

8、Control Ads visibility:
JNI
Now will show “admobTest” ad :

#include "AdmobHelper.h"

AdmobHelper::showAd();

9、编辑 .MK file:
Edit admobTest -> jni > Android.mk

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/AdmobHelper.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)
$(call import-module,cocos2dx/platform/third_party/android/prebuilt/libcurl)
$(call import-module,CocosDenshion/android)
$(call import-module,extensions)
$(call import-module,external/Box2D)
$(call import-module,external/chipmunk)
