[fanfalveto]

i try with this

Dim i As Intent      
i.Initialize(activiv,"")
            i = pp.GetApplicationIntent(activiv)         
   Log(i)
          If i.IsInitialized Then 
          Try
               StartActivity(i)      
               Catch
               ToastMessageShow("Aplicación no disponible/Application not available", False)   
               End Try
            Else            
               ToastMessageShow("Aplicación no disponible/Application not available", False)            
            End If

com.android.phone

only runs ok in rooted devices (i try in two rooted an one not rooted),any idea ? "activiv" is like this.thank you
