    Hello,
    I am going crazy with a specific project : till this morning I can not see any logged information using Log or LogColor from services created using v5.02

    I mean that : when I create a service with v5.02 and put Log("blabla") in Service_Start, I can see the service Start in the log window but not the sentence I've put.

    I returned back to v4.30 and saw the logged information. After that I have mixed a module created with v4.30 and one created with v5.02. The one created with v5.02 didn't displayed the logged information.

    I am turning crazy because it is hard to prove and to understand : I created a new project and mixed exactly some modules and it worked...

    Edit : Erel, I didn't want to disturb you by sending the project directly to you but if you could agree I would be glad to submit it to you as, I have checked all and I can not understand what happens (I won't export it but copy the whole folder : perhaps something in the sources)...

    Hi,

    I am the same problems, however, here's a solution for you:

    Code:
    Sub writelog(m As String)
       
       
    Dim s As OutputStream, b() As Byte  
       
    Dim TimeFormat, myTimeFormat As String
       
       
    Try
         
    ' // save existing time format
         TimeFormat = DateTime.TimeFormat
             
         myTimeFormat = 
    "HH:mm:ss.SSS"
         
    ' // set date time format
         DateTime.TimeFormat = myTimeFormat
         
    ' // debugger logging
         Log(DateTime.Date(DateTime.Now) & " " & DateTime.time(DateTime.Now) & " - " & m)
         
    ' // create log data for file
         m = DateTime.Date(DateTime.Now) & " " & DateTime.time(DateTime.Now) & " - " & m & Chr(10) & Chr(13)
         
    ' // restore date time format
         DateTime.TimeFormat = TimeFormat
         
         b = m.GetBytes(
    "UTF8")
         
         
    If File.ExternalWritable = False Then
           
    If File.Size(File.DirInternal, "yourappname.log") >= 1048576 Then
             
    File.Delete(File.DirInternal, "yourappname.log")
           
    End If
           s = 
    File.OpenOutput(File.DirInternal, "yourappname.log"True)
           
         
    Else
           
    If File.Size(File.DirDefaultExternal, "yourappname.log") >= 1048576 Then
             
    File.Delete(File.DirDefaultExternal, "yourappname.log")
           
    End If
           s = 
    File.OpenOutput(File.DirDefaultExternal,"yourappname.log"True)
         
    End If
         
         s.WriteBytes(b,
    0,b.Length -1)
         s.Flush
         s.close

         
       
    Catch
         
    Log("writelog, error - " & LastException.Message)
       
    End Try
         
       
    End Sub
    Also download https://play.google.com/store/apps/details?id=com.theolivetree.ftpserver from the playstore, and also install notepad++, https://notepad-plus-plus.org/.

    I use this combination to get my logging information. I remember that android changed the way some log data is displayed so on some devices you dont get any. Notepad ++ will detect a change in the log file and update the view for you.

    Hope this helps

    John.

    Hello John,
    Please forgive me if I don't know how to really thank you for your idea and the amount of useful information you provided. I am a bit stressed with that issue.
    Your idea is more than useful but doesn't fix my problem : in fact I wonder if any code is executed. I mean that Writelog() works pretty well but, believe it or not, from the service I was talking about, nothing is... logged. OF course, other parts are logged correctly...

    Note that there is no real difference between v5 modules and v4.3 modules. You can safely ignore the warning message.

    Are you testing it in debug mode or release mode? Are you using B4A-Bridge?

    Hello Erel,
    I am testing in "Release obfuscated" mode and directly connected to a real device via USB.
    Sorry to repeat : the module created with the version 4.30 does print its log. I have took a look at the "java source" (in objects \ src) and the file does include the logging
    Code:
    //BA.debugLineNum = 26;BA.debugLine="LogColor(\"Idle\",Colors.Blue)";
    anywheresoftware.b4a.keywords.Common.LogColor(
    "Idle",anywheresoftware.b4a.keywords.Common.Colors.Blue);
    I really don't understand what happens. Thanks for the confirmation about the compatibility between both versions too.
