Unity 微信支付和分享接入的一些流程和问题(Android)
March 16, 2019使用
用As新建一个Module，在Gradle 的 dependencies 里 添加api 'com.tencent.mm.opensdk:wechat-sdk-android-without-mta:+'引入依赖库。不过建议单独下载jar文件引入 如：compile files('libs/wechat-sdk-android-without-mta-5.1.6.jar')
代码在最后面
遇到的一些问题
-
闪退
需要在 Manifest.xml 的主Activity 添加这两行
<!-- 需要添加以下两条配置--> <meta-data android:name="unityplayer.UnityActivity" android:value="true" /> <meta-data android:name="unityplayer.ForwardNativeEventsToDalvik" android:value="false" /> -
错误码 “-6” 问题
主要因为签名错误（可以核对签名MD5值 快速检查）。同时，更换签名后，可能需要卸载掉微信重装才可以彻底解决，这点很重要。
-
“由于不支持的分享类型，无法分享到微信”
百分之百 APPKEY 错误。
支付分享等接口 Unity 用
支付，分享网址、小程序、图片等
