Android calls micro-letter login, share, pay _android

With the micro-mail SDK all kinds of pain, feel more trouble than QQ SDK call, callback is too troublesome, but also must be in the name of the designated package Actvity callback, so I write a blog here, there is a need for friends can learn from, and later their other projects useful to have a look for information.

A. Micro-letter landing is divided into three steps:

1). Micro-Letter Authorization Login
2. According to the authorization login code to obtain the user token
3). Obtain user information according to token
4. Receive micro-letter request and return value if your program needs to receive a request from a micro-letter or receive a response to a micro-letter request, the following 3 steps are required:

A. Create a new Wxapi directory in the appropriate directory of your package name and add a wxentryactivity class to the Wxapi directory, which inherits from activity (for example, the package name of the application is Net.sourceforge.simcpux,

The newly added class is shown in the following illustration)

and add the exported attribute to the manifest file, set to True, for example:

B. Implement the Iwxapieventhandler interface, the request sent by the micro-mail will be recalled to the Onreq method, and the response sent to the micro-letter request will be recalled to the Onresp method
C. Intent received in wxentryactivity and objects that implement the Iwxapieventhandler interface are passed to the Iwxapi interface Handleintent method, as shown in the following illustration:

Two. Micro-letter sharing directly invoke the SDK on the line, callback and login callback class is the same, according to the type of baseresp to distinguish between landing or sharing.

Three. Micro-credit Payment

1). Send a payment request

2. Receive the return value of the micro-letter payment (with the receive micro-letter login.) The return value of the share is similar, I do not write the detailed procedure.

Four. Put the code to explain

I landed, shared, and paid into a class, and you can refer to this class. 6 methods are encapsulated, and I'll introduce you to a few of the methods I need.

1. Construction method: Initializing the object, by the way of initializing the micro-object, the APP_ID register to the micro-letter

2. Login () initiate a login request to get code in the micro-mail login monitor actviity

3). Getaccesstoken (String code) after you have obtained the code from the listening activity, you can obtain the micro-access token by this method.

4). Getweixinuserinfo (final Weixintoken obj) gets the micro-subscriber information to pass in a Weixintoken object, which is the return value of the third step

5). Share (Final Boolean friendscircle,final videob videob) share to friends or friends if you have to share the picture, the picture is too large must be compressed, micro-letter official website description picture can not be big

In 32KB

6). iswxappinstalled () Check whether the micro-letter is installed

7. Wxpay (Final baseactivity activity,string order_id,string paytype) micro-letter payment for our project micro-credit some of the parameters are saved on the server, so I also asked for my own

Server, if you are placed locally, direct copy of the callback function inside the code can. Get payment status code in micro-credit payment listening actviity

Payreq class attribute corresponding meaning please refer to the micro-letter Official document: Https://pay.weixin.qq.com/wiki/doc/api/app.php?chapter=9_12

Micro-mail login and share request with return value    I'm landing here. The state of sharing is to send the broadcast out and then end the current activity.

Micro-Credit payment request and return value of the receive    micro-payment is also sent broadcast, if you still have the demand to judge the payment success or failure, you can in the broadcast intent to participate in the message

/** * Micro-Credit Payment callback activity * @author Ansen * @create Time 2015-08-29/public class Wxpayentryactivity extends Activi 
   
  Ty implements iwxapieventhandler{private Iwxapi Wxapi;

      }else{//Toast.maketext (this,r.string.wxpay_success, 0). Show (); 
  } finish ();  } 
   
}

It is important to note that the packet name and the class name that receive the micro-letter request and return value, the package name is the application's package name + ". Wxapi" class name must be a micro-letter specified class name and these two activity must be registered in Androidmanifest.xml, Upload a screenshot of the package name and class name that I made in the app

How to invoke a micro-letter login in an activity

1. Login broadcast listening internal class if you receive a broadcast, you get a micro-letter token.

Private class Wxentryreceiver extends Broadcastreceiver { 
  @Override public 
  void OnReceive Intent Intent) { 
    mlog.i ("Wxentryreceiver", "receiving micro-letter landing broadcast"); 
    if (mlog.debug) 
      showtoast ("Receive micro-letter landing broadcast"); 
    if (Intent.getaction (). Equals (Apidefineconst.broadcast_action_weixin_token)) { 
      int errcode = Intent.getextras () . GetInt ("Errcode"); 
      if (mlog.debug) 
        System.out.println ("Get Error code:" +errcode); 
      if (errcode==baseresp.errcode.err_user_cancel| | errcode==baseresp.errcode.err_auth_denied) { 
        requestdatafinish (); 
      } else{ 
        String code = Intent.getextras (). getString ("code"); 
        Xintestpresenter.getaccesstoken (code);}} 
   

2). Define member variables

3). Register for broadcast in OnCreate

Micro-letter Landing broadcast 
wxentryreceiver= new Wxentryreceiver (); 
Localbroadcastmanager LBM = Localbroadcastmanager.getinstance (this); 
Intentfilter filter = new Intentfilter (); 
Filter.addaction (Apidefineconst.broadcast_action_weixin_token); 

4). Call micro-letter Landing

Weixinpresenter xintestpresenter=new Weixinpresenter (this); 

Call in the activity of micro-letter sharing and calling the micro-letter payment code I will not post, I this blog just to give you a reference to the place, encounter problems or suggest the first time to see the official document.

Tell me about the problem I'm doing on the micro-mail landing.

1. Micro-letter landing, sharing, payment callback of the activity package name and class name must be strictly in accordance with the requirements to write

2. The activity that receives the callback is the activity must be registered in the Androidmanifest.xml

There are two constants in 3.WeiXinPresenter app_id and secret have to go to the micro-letter application. When you copy code, you assign these two constants

4. May visit the Network God Horse also needs some privileges remember to add permissions in Androidmanifest.xml

5. Call the micro-letter landing, sharing, payment your installation package must have a signature, the signature information must be with you on the micro-trust Web application signed information consistent with

6. Micro-letter without customer service support .... If there's a problem, see the official demo or the official API

7. Micro-mail SDK is often upgraded, if you have the latest development of the latest bar ...
