PayAndroid

对微信支付和支付宝支付的App端SDK进行二次封装，对外提供一个较为简单的接口和支付结果回调

注意注意：支付宝开放平台新支付的通知！

支付宝升级了支付模式，增加开放平台的概念，之前只要在商户平台申请pid即可实现支付，现在是在开放平台创建App，根据相应APP_ID发起支付。更新后调用方式不变。

2. 新版本接口支付 pay_param生成参见：http://www.jianshu.com/p/59341ea9d86d

1. 如何添加

在app目录下的build.gradle中添加依赖

compile 'com.tsy:pay:1.0.0'

2. Android Manifest配置

权限声明

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

注册activity

        <!-- 微信支付 -->
        <activity
            android:name="com.tsy.sdk.pay.weixin.WXPayCallbackActivity"
            android:configChanges="orientation|keyboardHidden|navigation|screenSize"
            android:launchMode="singleTop"
            android:theme="@android:style/Theme.Translucent.NoTitleBar" />

        <activity-alias
            android:name=".wxapi.WXPayEntryActivity"
            android:exported="true"
            android:targetActivity="com.tsy.sdk.pay.weixin.WXPayCallbackActivity" />

        <!-- 支付宝支付 -->
        <activity
            android:name="com.alipay.sdk.app.H5PayActivity"
            android:configChanges="orientation|keyboardHidden|navigation"
            android:exported="false"
            android:screenOrientation="behind"></activity>
        <activity
            android:name="com.alipay.sdk.auth.AuthActivity"
            android:configChanges="orientation|keyboardHidden|navigation"
            android:exported="false"
            android:screenOrientation="behind"></activity>

3. 发起支付

3.1 微信支付

   /**
     * 微信支付
     * @param pay_param 支付服务生成的支付参数
     */
    private void doWXPay(String pay_param) {
        String wx_appid = "wxXXXXXXX";     //替换为自己的appid
        WXPay.init(getApplicationContext(), wx_appid);      //要在支付前调用
        WXPay.getInstance().doPay(pay_param, new WXPay.WXPayResultCallBack() {
            @Override
            public void onSuccess() {
                Toast.makeText(getApplication(), "支付成功", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onError(int error_code) {
                switch (error_code) {
                    case WXPay.NO_OR_LOW_WX:
                        Toast.makeText(getApplication(), "未安装微信或微信版本过低", Toast.LENGTH_SHORT).show();
                        break;

                    case WXPay.ERROR_PAY_PARAM:
                        Toast.makeText(getApplication(), "参数错误", Toast.LENGTH_SHORT).show();
                        break;

                    case WXPay.ERROR_PAY:
                        Toast.makeText(getApplication(), "支付失败", Toast.LENGTH_SHORT).show();
                        break;
                }
            }

            @Override
            public void onCancel() {
                Toast.makeText(getApplication(), "支付取消", Toast.LENGTH_SHORT).show();
            }
        });
    }

3.2 支付宝支付

   /**
     * 支付宝支付
     * @param pay_param 支付服务生成的支付参数
     */
    private void doAlipay(String pay_param) {
        new Alipay(this, pay_param, new Alipay.AlipayResultCallBack() {
            @Override
            public void onSuccess() {
                Toast.makeText(getApplication(), "支付成功", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onDealing() {
                Toast.makeText(getApplication(), "支付处理中...", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onError(int error_code) {
                switch (error_code) {
                    case Alipay.ERROR_RESULT:
                        Toast.makeText(getApplication(), "支付失败:支付结果解析错误", Toast.LENGTH_SHORT).show();
                        break;

                    case Alipay.ERROR_NETWORK:
                        Toast.makeText(getApplication(), "支付失败:网络连接错误", Toast.LENGTH_SHORT).show();
                        break;

                    case Alipay.ERROR_PAY:
                        Toast.makeText(getApplication(), "支付错误:支付码支付失败", Toast.LENGTH_SHORT).show();
                        break;

                    default:
                        Toast.makeText(getApplication(), "支付错误", Toast.LENGTH_SHORT).show();
                        break;
                }

            }

            @Override
            public void onCancel() {
                Toast.makeText(getApplication(), "支付取消", Toast.LENGTH_SHORT).show();
            }
        }).doPay();
    }

Demo使用

项目中Demo支付宝支付可以直接使用。微信支付需要修改以下：

1. appid需要替换为自己的微信appid
2. PackageName和ApplicationId设置为自己的（与微信开放平台填入的包名一致）
3. 使用自己的签名进行打包（与微信开放平台填入签名一致）

Demo示例：

混淆

#pay
-dontwarn com.tsy.sdk.pay.**
-keep class com.tsy.sdk.pay.**{*;}

#weixin
-dontwarn  com.tencent.**
-keep class com.tencent.** {*;}

#alipay
-dontwarn com.alipay.**
-keep class com.alipay.** {*;}

-dontwarn  com.ta.utdid2.**
-keep class com.ta.utdid2.** {*;}

-dontwarn  com.ut.device.**
-keep class com.ut.device.** {*;}
