Android Question Answered: LogCatStart - event not firing

[Lee Gillie CCP]

Phone.LogCat is very short on examples. I am trying to capture 5,000 characters in a round robin. In this way, at any moment I can capture recent LOGCAT from devices running the software in the field.

From a module named Globals:

Sub Process_Globals
          ...
    Private logcat As LogCat
    Private logString As StringBuilder
End Sub

Public Sub Init
             ...
    logString.Initialize
    logcat.LogCatStart(Array As String(),"logcat")       
End Sub

Sub logcat_LogCatData(Buffer() As Byte, Length As Int)
    Dim data As String
    data = BytesToString(Buffer,0,Length,"UTF-8")
    logString.Append(data)
    If logString.Length > 5000 Then
        logString.Remove(0,logString.Length-5000)
    End If
End Sub

I have added this with the Manifest Editor:

AddPermission(android.permission.READ_LOGS)

my logcat_LogCatData routine is apparently never called.

I have experimented with Args...
"-v long"
"-v"
neither affect non-execution of the event.

It fires fine from the main activity with similar code. Can not seem to figure out how to hook the handler from a module. But I suspect I won't get event delivery when other activities are stacked over the main activity? Is there a way to keep this constantly and continuously monitoring? The point is to have ALL recent LOGCAT to report in a crash dump in the event of an error.

You should use a service to handle the events. You can see an example in B4A-Bridge source code.

Note that the LogCatData event is a special event and it is executed on a different thread.

Ok, adding a service module. I don't see how to get this run down, so will post a new question.
