Connection reported as Connection.NONE
--------------------------------------
Key: CB-77
URL: https://issues.apache.org/jira/browse/CB-77
Project: Apache Callback
Issue Type: Bug
Components: Android
Reporter: Simon MacDonald
To be pursuant with Apple guidelines, I recently put checks into my code to
detect offline/online status for my apps and alert accordingly. I used this
function to detect:
function isOnline() {
// Presume online unless PhoneGap or HTML5 tell us otherwise.
if (navigator.network && navigator.network.connection.type == Connection.NONE) {
return false;
}
if (navigator.onLine && typeof navigator.onLine == 'boolean' &&
navigator.onLine === false) {
return false;
}
return true;
}
This works as expected for me, but for one of my users (on an Android 2.3), it
reports Connection.NONE even when they have perfect reception. So I'm no longer
using the network.connection status.
Maybe it doesn't work for some carriers? Or it shouldn't be relied upon for
disabling functionality?
@pamelafox that is a weird one. Going back over the code the only time
Connection.NONE should be returned is when the the NetworkInfo object is null
or it's isConnected() method returns false.
Perhaps there is a window as the application starts up where the network info
is not ready. Are you making this check after a deviceready event?
@pamelafox Can you ask your user if they are roaming when the have this
problem? If so I think it may be a bug with Android itself.
