Android Question Gmail , WhatsApp , messages in queue. alert to user

[Daniel-White]

Hi folks. I have the big curiosity, how Gmail, WhatsApp and so on, can show the messages in queue.? An example the next figures show it. How by code these programs can add the number like WhatsAPP the number 1 ,etc. and tell to end user he has one or two etc messages waiting to read.?
Thanks you

This is not a standard Android feature. However you can add such a number to Samsung and Sony devices with the intents described here: http://stackoverflow.com/questions/...nt-to-application-icon-on-sony-xperia-devices

Sorry, I read a long time ago about Widgets and that picture reminds me of them. Nothing to do?


P.S.

I wonder how it is possible to distinguish a link from a widget; seemingly they are equal. But the WhatsApp Chat is a widget, I'm seeing now

Hi,

this code works on Samsung devices :

Mainfest :

AddPermission("com.sec.android.provider.badge.permission.READ")
AddPermission("com.sec.android.provider.badge.permission.WRITE")

Private cr As ContentResolver

Try
                                    Dim cv As ContentValues
                                    cv.Initialize
                                    cv.PutString("package", "PACKAGENAME")
                                    cv.PutString("class", "PACKAGENAME.main")
                                    cv.PutInteger("badgecount", iCount)
                                    Dim u As Uri
                                    u.Parse("content://com.sec.badge/apps")
                                    cr.Insert(u, cv)
                                Catch
                               
                                End Try

Clear :

Private cr As ContentResolver

Try
        Dim cv As ContentValues
        cv.Initialize
        cv.PutString("package", "PACKAGENAME")
        cv.PutString("class", "PACKAGENAME.main")
        cv.PutInteger("badgecount", 0)
        Dim u As Uri
        u.Parse("content://com.sec.badge/apps")
        cr.Update(u, cv, "", Null)
    Catch
   
    End Try
