安卓接入支付宝支付

1. 下载支付宝jar包

存放位置如下

2.将jar包添加进依赖

compile files('libs/alipaySdk-20180316.jar')

3.添加权限

<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" />

4.添加活动

<activity
    android:name="com.alipay.sdk.app.H5PayActivity"
    android:configChanges="orientation|keyboardHidden|navigation|screenSize"
    android:exported="false"
    android:screenOrientation="behind"
    android:windowSoftInputMode="adjustResize|stateHidden" >
</activity>
<activity
    android:name="com.alipay.sdk.app.H5AuthActivity"
    android:configChanges="orientation|keyboardHidden|navigation"
    android:exported="false"
    android:screenOrientation="behind"
    android:windowSoftInputMode="adjustResize|stateHidden" >
</activity>

5.在proguard-ules.pro文件中添加混淆,该文件在build.gradle下面

-keep class com.alipay.android.app.IAlixPay{*;}
-keep class com.alipay.android.app.IAlixPay$Stub{*;}
-keep class com.alipay.android.app.IRemoteServiceCallback{*;}
-keep class com.alipay.android.app.IRemoteServiceCallback$Stub{*;}
-keep class com.alipay.sdk.app.PayTask{ public *;}
-keep class com.alipay.sdk.app.AuthTask{ public *;}
-keep class com.alipay.sdk.app.H5PayCallback {
    <fields>;
    <methods>;
}
-keep class com.alipay.android.phone.mrpc.core.** { *; }
-keep class com.alipay.apmobilesecuritysdk.** { *; }
-keep class com.alipay.mobile.framework.service.annotation.** { *; }
-keep class com.alipay.mobilesecuritysdk.face.** { *; }
-keep class com.alipay.tscenter.biz.rpc.** { *; }
-keep class org.json.alipay.** { *; }
-keep class com.alipay.tscenter.** { *; }
-keep class com.ta.utdid2.** { *;}
-keep class com.ut.device.** { *;}

6.新建类PayResult

package com.example.test.alipaytest.alipay;

import android.text.TextUtils;

import java.util.Map;

/**
 * Created by app-i on 2018/3/24.
 */

public class PayResult {

    private String resultStatus;
    private String result;
    private String memo;

    public PayResult(Map<String, String> rawResult) {
        if (rawResult == null) {
            return;
        }

        for (String key : rawResult.keySet()) {
            if (TextUtils.equals(key, "resultStatus")) {
                resultStatus = rawResult.get(key);
            } else if (TextUtils.equals(key, "result")) {
                result = rawResult.get(key);
            } else if (TextUtils.equals(key, "memo")) {
                memo = rawResult.get(key);
            }
        }
    }

    @Override
    public String toString() {
        return "resultStatus={" + resultStatus + "};memo={" + memo
                + "};result={" + result + "}";
    }

    /**
     * @return the resultStatus
     */
    public String getResultStatus() {
        return resultStatus;
    }

    /**
     * @return the memo
     */
    public String getMemo() {
        return memo;
    }

    /**
     * @return the result
     */
    public String getResult() {
        return result;
    }
}

7.主要代码如下

package com.example.test.alipaytest;

import android.annotation.SuppressLint;
import android.os.Handler;
import android.os.Message;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

import android.util.Log;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;

import com.alipay.sdk.app.PayTask;
import com.example.test.alipaytest.alipay.PayResult;

import org.w3c.dom.Text;

import java.util.Map;

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    private static final int SDK_PAY_FLAG = 1;

    @SuppressLint("HandlerLeak")
    private Handler mHandler = new Handler() {
        @Override
        @SuppressWarnings("unused")
        public void handleMessage(Message msg) {
            /**
             *对于支付结果，请商户依赖服务端的异步通知结果。同步通知结果，仅作为支付结束的通知。
             * 也就是说,这里的通知只是支付宝返回的支付结果,另外还需要获取服务端返回的信息.
             */
            switch (msg.what) {
                case SDK_PAY_FLAG:
                    PayResult payResult = new PayResult((Map<String, String>) msg.obj);
                    String resultInfo = payResult.getResult();
                    String resultStatus = payResult.getResultStatus();
                    /**
                     * 判断resultstatus,为9000则是支付成功,否则失败
                     * 9000这里有漏洞,需要深入判断??
                     */
                    if (TextUtils.equals(resultStatus, "9000")) {
                        /**
                         * 真实支付结果还需要依赖服务端返回的信息.
                         */
                        Toast.makeText(MainActivity.this, "支付成功", Toast.LENGTH_SHORT);
                    } else {
                        Toast.makeText(MainActivity.this, "支付失败", Toast.LENGTH_SHORT);
                    }

                    break;

                default:
                    break;
            }

        }
    };

        pay.setOnClickListener(this);
    }
