Unity上线google商店 用IL2Cpp打包64位版本和Android APP Bundle优化 及产生的bug

ios刚上线，这边着手改成android版本，我开始使用的是unity2017.4.1版本

上传谷歌商店是出现这两个警告：

要支持64位，但是在2017版本上没有找到64位的打包选项，猜测应该是版本的问题，上网查询果然是

以下是我查询的：

https://www.cnblogs.com/cnxkey/articles/9760391.html

http://tieba.baidu.com/p/5496282855

http://dy.163.com/v2/article/detail/E9LQND6M0526E124.html

怎样打包64位和Androi APP Bundle上面他们讲解的都很详细，而且还讲解了为什么google要支持64位，非常感谢他们分享。

一：我下载了新的unity2018.4.1，开始先键一个demo，里面就随便建了个ui，然后开始打包

1:在PlaySettings->other settings->Scriptiing Backend 选择IL2CPP（默认是Mono）,

c++ Compiler Configuration 选择Release

Target Architectures 里面的Arm64就是可以说勾选的了，勾选打包即可

2:Androi APP Bundley优化在Build Sttings 勾选Build App Bundle（Google Play）即可，打出的是aab包

 打包运行成功。

注：要死测试的话就用Mono打包吧，毕竟IL2CPP打包要慢上几倍

二：2017.4.1转成2018.4.1时产生的部分bug

1:google admob 产生广告bug

在2017.4.1广告是没问题的，移植到2018版本出现此问题

解决方法：Assets->Play services Resolver ->Android Resolver->Resolve 解决

但由此可能产生下面打包的bug

2：产生的打包的Gradle错误

解决方法:出现这种问题是jar包重复。

Temp\gradleOut\build\intermediates\transforms\dexBuilder\release\3.jar（我的最后一个是3.jar，可能不一样）中可以看到：Program type already present: android.support.v4.accessibilityservice.AccessibilityServiceInfoCompat
说明android.support.v4已经存在，就是说有两个，一个新的一个旧的，找到删掉就可以

我的是 support-v4-compat.jar和刚刚导入的 com.android.support.support-v4-26.1.0重复，我删掉了support-v4-compat.jar，就可以打包了

解决方法：查看中断信息：

在未经处理的异常:下面一段找到error，error: undefined reference to '_copyToPasteboardWithText'

error：undefined reference to '_shareWithText'，说未定义的引用。
 这个可能是你ios的调用方法（我的是ios的方法），然后在代码中找到用条件编译命令#if改掉就ok了

我的方法

[DllImport("__Internal")]
private static extern void _copyToPasteboardWithText(string text);

改成
#if UNITY_IOS
[DllImport("__Internal")]
private static extern void _copyToPasteboardWithText(string text);
#endif

所有问题解决，完美打包运行！！！

有什么问题或错误的地方欢迎讨论指正，谢谢。
