在 Android 市场中以编程方式检查我的应用程序版本

问题描述

目前我正在检查应用程序版本代码，并将其与我服务器上的最新版本代码匹配，并根据此匹配发送用户从 Android 市场获取最新更新.

Currently I'm checking the app version code on launch and match it with latest version code on my server and based on this matching I send user to get latest update from Android market.

它运行良好，但我的问题是我必须手动更改服务器上的最新版本代码，而且我不知道新版本的 APK 何时在市场上激活.

It's working well but my problem is that I have to manually change the latest version code on my server and I don't know exactly when new version of APK gets activated in market.

有什么方法可以直接在安卓市场中查看应用的版本代码，这样当新的apk被激活时，我可以直接将用户发送到市场?

Is there any way to check version code of app in Android market directly so that I can send user directly to market when new apk gets activated?

推荐答案

Google Play 不提供任何用于检索元数据的官方 API.但是，您可以在 http://code.google.com/p/android-market- 查看非官方 APIapi/.

Google Play does not provide any official APIs for retrieving metadata. You could however, check the unofficial API at http://code.google.com/p/android-market-api/.

具体来说，请查看 Wiki 页面 HowToSearchApps.查询的响应包含版本信息:

Specifically, take a look at the Wiki page HowToSearchApps. The response to the query contains version information:
