android集成支付宝支付功能

</pre>首先申请支付宝商家账户…接着点击我的商家服务…下载下面的快捷支付压缩包……<p></p><p><img src="http://img.blog.csdn.net/20150409135734393?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQveWZ5a2lzc3NreQ==/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" width="770" height="840" alt="" /></p><p>解压压缩包…打开openssl文件夹…首先生成支付宝支付所必须的公秘和私钥……</p><p><img src="http://img.blog.csdn.net/20150409164314322?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQveWZ5a2lzc3NreQ==/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" width="620" height="300" alt="" /></p><p>私钥和公钥的生成文件openssl.exe必须在DOS下运行（最好直接打开opnssl.exe而不是使用DOS进入，笔者使用DOS进入的时候会莫名其妙的出现生成不了文件的情况）……</p><p>输入生成RSA私钥 命令……</p><p></p><pre name="code" class="plain">genrsa -out rsa_private_key.pem 1024

可以在\openssl\bin文件夹下面看到生成的RSA私钥文件

接着输入生成RSA公钥的命令

rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem

之后在\openssl\bin文件夹下生成了RSA公钥文件

最后将RSA私钥更改为PKCS8格式…输入命令…

openssl>pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt

将如图所示的字符拷贝出来…去除begin和end这两行…剩下的去除空格…作为客户端的私钥保存好…

登录支付宝商户账号…点开如图界面…

打开添加RSA秘钥…将刚刚所生成的RSA公钥填入并保存…

新建android工程…在libs文件夹下导入alipaysdk.jar…

在AndroidManifest.xml文件中加入如下代码……

        <!-- alipay sdk begin -->        <activity            android:name="com.alipay.sdk.app.H5PayActivity"            android:configChanges="orientation|keyboardHidden|navigation"            android:exported="false"            android:screenOrientation="behind"            android:windowSoftInputMode="adjustResize|stateHidden" >        </activity>        <activity            android:name="com.alipay.sdk.auth.AuthActivity"            android:configChanges="orientation|keyboardHidden|navigation"            android:exported="false"            android:screenOrientation="behind" >        </activity>        <!-- alipay sdk end -->

新建AliPayActivity.java……
