Ah, for those of you (like me) that are too lazy for that, I've made a replacement sub
B4X:
Sub Debug(Text As String)
Dim tempstr As TextWriter
tempstr.Initialize( File.OpenOutput(File.DirRootExternal,"error.txt",True) )
tempstr.WriteLine(Text)
tempstr.Close
End Sub
Then you can just collect error.txt off the root of their SD card
