I currently listen for changes in the Wi-Fi in my Android application and
for the most part it works OK, however when the user has there device is
idle/sleep mode, as in when the screen is blank. If they walk into a Wi-Fi
area and automatically connect I don't get the intent until the user has
turned on the screen. This is not good and leads to complaints about my
application. Can anyone help with why I don't get the intent until the
screen wakes up?
Here is my code:
BroadcastReciever:
public class WifiReciever extends BroadcastReceiver{
@Override
public void onReceive(Context arg0, Intent arg1) {
String action = arg1.getAction();
if (!action.equals(ConnectivityManager.CONNECTIVITY_ACTION)){
return;
}
if (!noConnectivity)
{
if (aNetworkInfo.getType() == ConnectivityManager.TYPE_WIFI)
{
//Handle connected case
Log.e("E", "GOT CONNECTION");
}
}
else
{
if (aNetworkInfo.getType() == ConnectivityManager.TYPE_WIFI)
{
//Handle disconnected case
Log.e("E", "LOST CONNECTION");
}
}
}
If a running Service I have that as a variable:
WifiReciever mConnectionReceiver;
And I start and stop the receiver in the service with the following calls:
private synchronized void startMonitoringConnection()
{
IntentFilter aFilter = new
IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION);
registerReceiver(mConnectionReceiver, aFilter);
}
private synchronized void stopMonitoringConnection()
{
unregisterReceiver(mConnectionReceiver);
}
I call a WakeLock to make sure that I am getting CPU time like this:
pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "CicCPULock");
wl.acquire();
However even with all that I never receive the Connectivity changed intent
if the screen is blank, it works 100% of the time when the screen is on bit
if I a user walks into a Wi-Fi are and connects when the screen is blank I
fail to get the intent, is anyone aware of something I am missing?
