How to check Internet Connection for every processing in Android?

Question

In my application, most of the processing in all Activity need to connect to Server to get data.
So, where should I check the Internet connection?
Is there any methods that can tell me when the connection is unavailable?
Finally, how to implement it? Is there any API for handle this case?

use the ConnectivityManager class and Context.getSystemService(Context.CONNECTIVITY_SERVICE) method. More information: http://developer.android.com/reference/android/net/ConnectivityManager.html

// just checks if network connectivity is available 
public boolean isNetworkConnected(Context context){
    ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    if (cm.getActiveNetworkInfo() != null && cm.getActiveNetworkInfo().isAvailable() && cm.getActiveNetworkInfo().isConnected()) return true;
    return false;           
}//end method

so, where should I call this and what can I do if connection return false? – jjLin Aug 24 '12 at 03:09
that's a whole new question...you call this when you need it, if it returns false you know there's no connection... – slinden77 Aug 24 '12 at 04:28
