===============================

准备

1,导入银联支付libs:UPPayAssistEx.jar;UPPayPluginEx.jar;

2,配置mainifest文件的activity:(UPPayPluginEx.jar中)和权限;

<activity 

android:name="com.unionpay.uppay.PayActivity"

android:label="@string/app_name" 

android:screenOrientation="portrait"android:configChanges="orientation|keyboardHidden"

android:excludeFromRecents="true" 

android:windowSoftInputMode="adjustResize"/>

=====================

private void UnionPay(){
Intent intent=new Intent();//测试用,自动生成一个tn;
intent.setClass(this, UnionPayBase.class);
startActivity(intent);
}

银联支付集成的很简单了,手续费还底:
