It follows these steps ::
它遵循以下步骤::
1 Create a Web Service which your app can poll whenever the app launches or based on some time limit that can check if there is new version out there.
This Web service should return the lastest Version of the apk file that is hosted on the Server along with the URI of the application file that has the new version.
When your app gets the response from the Web Service, it will parse the JSON and check your app version to the lastest version that is available on the server.
If your app version is lower than the latest version it will prompt the user to start the download process. The download of the new app is handled by the Download Manager.
The download manager will notify your app using Broadcast receiver when the download is complete.
After completion of the latest version of the application file the you can start the activity to install/update that file.
1 创建一个 Web 服务，您的应用程序可以在应用程序启动时轮询该服务，或者基于可以检查是否有新版本的时间限制。
此 Web 服务应返回托管在服务器上的 apk 文件的最新版本以及具有新版本的应用程序文件的 URI。
当您的应用从 Web 服务获得响应时，它会解析 JSON 并将您的应用版本检查为服务器上可用的最新版本。
如果您的应用程序版本低于最新版本，它会提示用户开始下载过程。新应用程序的下载由下载管理器处理。
下载完成后，下载管理器将使用广播接收器通知您的应用。
完成最新版本的应用程序文件后，您可以开始安装/更新该文件的活动。
