play-games-plugin-for-unity 與 googleads-mobile-unity 混用

雖然有人把google play services和admob的Unity3D plugin都寫好了，但同時使用也是要動手微調一下，不然可能就會碰到以下2種錯誤。
Failed to re-package resources

Unable to convert classes into dex format
先把Unity和plugin的版本列出

Unity3D 5.3

Unity3D的google play services plugin 0.9.34
https://github.com/playgameservices/play-games-plugin-for-unity

Unity3D的admob plugin 3.0.5
https://github.com/googleads/googleads-mobile-unity/releases

將2種plugin合起來用需要做些修改，可參考以下網址：
https://ndesostyle.wordpress.com/2016/02/10/conflict-with-latest-googleads-mobile-and-play-games-plugin-for-unity/

網頁上的重點是這一段字後面的影片連結：
Fixing google play games and admob plugin Unity. Video tutorial is Available  Youtube

可惜裡面用的版本有點舊了，我再把改的過程記錄一下。

1.先裝play-games-plugin-for-unity,若碰到
Unity3D No resource found that matches the given name (at 'value' with value '@integer/google_play_services_version').

錯誤,可先看之前這篇的方法

沒問題後再把admob plugin裝上

2.打開Assets/GooglePlayGames/Editor/GPGSUpgrader.cs

在97行的地方把以下2行註解掉

//string clientDir = "Assets/Plugins/Android/google-play-services_lib";
//GPGSUtil.DeleteDirIfExists(clientDir);

3.打開Assets/GooglePlayGames/Editor/GPGSDependencies.cs

在67行的地方註解掉

//svcSupport.DependOn("com.android.support",
//"support-v4",
//"23.1+");

後面加上

svcSupport.DependOn("com.google.android.gms",
"play-services-ads",
PluginVersion.PlayServicesVersionConstraint);

4.打開Assets/Plugins/Android/GoogleMobileAdsPlugin/AndroidManifest.xml

在23~25行註解掉

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

5.改好後回到Unity3D編輯器會跳出一個對話框內容如下

Remove or replace support-v4 version 23.4.0 with version 23.1.1?

我選了ok

6.這時就可以先Build看看了，若成功就可以到以下網址看Unity的admob範例

https://developers.google.com/mobile-ads-sdk/docs/games?hl=zh-tw#unity

7.若失敗也只能在找看看有沒有其它方法了，附上使用的android sdk，提供一些線索。
