編輯：關於Android編程
最近比較閒，公司項目更換後台，於是自己來研究微信支付和支付寶支付，把自己學習的過程寫下來，以備以後查看。
public class ParameterConfig {
public static final String GANHOST = "http://101.226.197.11"; //服務器地址ip（根據自己替換）
/**
* 微信
*/
//appid
public static final String WX_APP_ID = "";// 自己填寫自己項目的
// 商戶號
public static final String WX_MCH_ID = "";// 自己填寫自己項目的
// API密鑰，在商戶平台設置
public static final String WX_API_KEY = "";// 自己填寫自己項目的
//服務器回調接口
public static final String WX_notifyUrl = GANHOST+"/service/orderComplete";// 用於微信支付成功的回調（按自己需求填寫）
/**
* 支付寶
*/
// 商戶PID
public static final String PARTNER = "";//自己填寫自己項目的
// 商戶收款賬號
public static final String SELLER = "";//自己填寫自己項目的
// 商戶私鑰，pkcs8格式
public static final String RSA_PRIVATE = "";//自己填寫自己項目的
public static final String aliPay_notifyURL = GANHOST+"/service/alipay/orderComplete";//支付寶支付成功的回調

<uses-permission android:name="android.permission.INTERNET"> <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"> </uses-permission></uses-permission></uses-permission>
b.activity配置，這裡com.gan.mypay改成自己的包名（如果自己包名與src下的package 名不一樣，這裡要的是在manifest中配置的名稱，同樣需要在src建立以自己包 名為路勁的package,一定確保有這個activity）這個activity是微信支付結果要回調的activty
android:name="com.gan.mypay.wxapi.WXPayEntryActivity"<uses-permission android:name="android.permission.INTERNET"> <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission></uses-permission></uses-permission>
b.activity配置這裡必須要這麼配置
