Preface:

Recently, the company plans to first learn android technology, and then recruit Andirod, which is quite expensive. The boss plans to let me do it, so I will do it, and by the way, I will make some summaries. By transforming from Java background to android, I will quickly start with the small strategy of Android.

Andoird website address developer. The android. Google. Cn /

Introduction:

First check for alipay docs.open.alipay.com/200/105311/ sandbox document
This document goes into a lot of detail
Then go to get appID and other accounts, there are encrypted secret keys and other content
The next step is the code
The official demo is for the convenience of putting all the code on Android
I’ve split up the code for your convenience and put it in the Server and put it in the Android Center

demo:

Download.csdn.net/download/we…
Here in order to facilitate the pure development of Java background friends also brought up before I talked about webView mixed development code
In mixed development, Java method is invoked through JS and then alipay method is started to realize payment
I’m not going to do too much here

Let’s look at my directory structure

The red areas are all important to focus on

Copy the code

In addition to the appID and the secret key in the table there is a method to put on the server and the rest of the android is OK
For references to aar packages, read the official documentation
In the demo, some codes in the Alipay directory are also placed on the server side
Some of these methods are in TextUitl classes and Java Server probably doesn’t have the ability to create a class of its own and put in comparison methods and nulls

Activit code

<? The XML version = "1.0" encoding = "utf-8"? > <android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity"> <WebView android:id="@+id/webview" android:layout_width="match_parent" android:layout_height="733dp" tools:layout_editor_absoluteX="0dp" tools:layout_editor_absoluteY="0dp" /> <TextView android:id="@+id/tv_result" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Hello World!" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintLeft_toLeftOf="parent" app:layout_constraintRight_toRightOf="parent" app:layout_constraintTop_toTopOf="parent" /> <Button android:id="@+id/payV2" android:layout_width="match_parent" android:layout_height="wrap_content" android:onClick="payV22" android:text="@string/pay_with_alipay" android:textAllCaps="false" tools:layout_editor_absoluteX="0dp" tools:layout_editor_absoluteY="180dp" /> </android.support.constraint.ConstraintLayout>Copy the code

The important thing in an activity is a button click button that doesn’t do anything else
Inside there is a WebView to facilitate development and use, don’t need to directly delete the key is good

Summary ideas:

The idea of Integrating Alipay with Android is to directly start the contents of Alipay by calling alipay

Server development ideas

Look at the picture

This section focuses on the Server policy
1. The client sends a request to the server to obtain encrypted data and add signatures
2. The server parses the user information after obtaining the request
3. Then generate encrypted data and signed data through the code in demo
4. Send the information to the client
