原标题:Android Post Form data when network is not available

I have a simple form with 4 fields that i submit to remote mysql data on submit. When there is no connection available this form fails to send data. I know i can store data in sqlite, but i m not sure how to send this data to mysql db when app is not running and network is available? Can anyone point me to some samples that i can help me with this?

注册广播接收器android.net.conn。 CONNECTIVITY_CHANGE。 然后检查网络是否可行,如果是的话,则发送所节省的数据。 或者,仅仅检查所节约的数据,然后发送您的 app。

There s no way to send your data anywhere if your application is not running. You may try instead to look for saved data every time your application starts, and send it if such data exists and network connection is available.

如果用户不再开始应用,所节约的数据会发生什么情况? 或许(s)不需要。
