This article for everyone to share the Android micro-letter payment source code for your reference, the specific content as follows

Parameter configuration

public static final String app_id;
/**
registers the app on the micro-trust platform, **/the assigned ID to the public
static final String mch_id;
/**
apply for the opening of micro-letter payment, after the success of the micro-letter will send you an e-mail, to assign you a merchant platform account, in the information has a merchant ID
**/public
static final String api_key;
/** in the letter sent to you in the
e-mail, give you the distribution of the micro-letter merchant platform account, in which set a api_key
**/

Get to PREPAY_ID

All of the above configuration is correct and you will get the result that the micro-letter returns:

<xml><return_code><! [cdata[success]]></return_code>
<return_msg><![ Cdata[ok]]></return_msg>
<appid><![ Cdata[wx8760819e9228eab6]]></appid>
<mch_id><![ Cdata[1244336402]]></mch_id>
<nonce_str><![ Cdata[p7f4pu6kk8ci3vbi]]></nonce_str>
<sign><![ cdata[598ade81cdeefbef1e7a9e4f73b03cd4]]></sign><result_code><! [cdata[success]]></result_code>
<prepay_id><![ cdata[wx20151210110830853e5daa560147579483]]></prepay_id>//successfully fetched the prepaid ID
<trade_type><![ Cdata[app]]></trade_type>
</xml>

When you take the second step, you may have problems:

result_code><! [cdata[app_id does not match merchant ID]]></result_code>//Merchant ID is not correct
result_code><! [cdata[signature error]]></result_code>//in assembling product parameters, Chinese class, to specify the code, otherwise garbled, will report this error;

Successfully obtained, prepay_id, this time, the payment interface still can't adjust?

/*** Note:
1. If you are applying for a micro-letter payment app that is registered on a micro-trust platform and uses the Eclipse default signature, you can now adjust the payment page in the development environment
2. If, in an open platform app, the signature uses a custom signature, you need to use that signature to pack and then run up and you can tune its micro-mail payments
***/

Where is the callback for the micro-credit payment result?

1.app client, we accept the callback result of payment in this class

/**
The place to paint, you need to change into your own app_id
**/

Attention:

/** 
This activity, is a transparent activity, the callback is over, you need to end it * 
2. Service-side 
**/

packageparams.add (New Basicnamevaluepair (" Notify_url "," http://121.40.35.3/test "));
/**
