Android background services (like Viber) -


I am developing a small VoIP application and I need to stay connected to the server.

A push notification is used first (to wake the device on incoming calls), but Android push notifications are not reliable due to very long heartbeat intervals.

The second solution was that start startground () . This method works, but leaves an icon in the notification bar (I know it should be, but please read).

If I startForeground () then sleeps as soon as T phone.

TLDR: There is no background service without Viber () but it still works if the phone is sleeping and accepts incoming calls (even here That with push notice disabled) how do they do this?

I think they hold a permanent TCP connection and AlarmManager To take the phone with the interval (let's say 5 minutes) and keep the connection alive.

Check.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
