转载之前我想深深地感谢屌丝哥

 

相信相同过App获取利润的都会需要接入计费SDK,下边就跟大家走一遍完整的支付宝SDK接入,支付系列均通过计费Button触发,计费所有代码均放到一个java文件实现,这样虽然会有点违背java面向对象及封装性,但这样做的一个好处是可以快速集成到不同的游戏中,将改动的文件降到最低,各有利弊吧,如果大家有什么更好的方法,望一起交流,好了,废话不多说了,开始干活。

PS:初次写博文,各方面还不够完善,看到此博文的朋友有什么意见或者建议请回复或者留言,你们的支持是我最大的动力。
注意事项
1.添加android.permission.INTERNET权限和android.permission.ACCESS_NETWORK_STATE权限
2.代码中出现注释的地方重点看,没注释的地方可以不看
3.想获取支付宝合作商户ID,及支付宝公钥请点击支付宝链接,生成密钥及PKCS8转码工具在文档中
