Android Question B4A: IDE: How to really delete the Logs?

[Jehoschua]

Good evening

the B4A Logs has a "Clear" button. Unfortunately, it does not clear the log, it's just similar to a "clear screen" in a shell and all the old Logs comes back really fast (e.g. if the App is restarted :-()

Because we're usually not interested in old Logs or exceptions (especially, if we restart the App):
how can we really delete the old Logs?

Thanks a lot for any help!,
kind regards,
Thomas

You cannot as the logs are not kept in the IDE but rather in the Android device itself.

the b4a-bridge not have access to this logs?

The Bridge can not delete the log from the Device if you mean this.

there is a way if you have this device connected via usb at pc.
open a cmd window (or make a batch file)

D:
cd D:\Android\SDK\platform-tools
adb.exe logcat -c

Android Debug Bridge can also connect via wifi, see "Connect to a device over Wi-Fi"

No. Apps can only read their own logs and they cannot clear the logs.

Thanks a lot for your clarification!,
as it is the Androids local App Logfile, we can easily delete it on each startup (it's probably the same command which other IDEs are using if the 'clear log on startup' configuration flag is set):

Sub Activity_Create(FirstTime As Boolean)
    ClearLog
    Log("Start")
End Sub

' Clears the Android's local App Log - and therefore the IDE Log, too
Sub ClearLog()
    Dim PB As JavaObject
    Dim Commands As List: Commands.Initialize
    Commands.Add("logcat")
    Commands.Add("-c")
    PB = PB.InitializeNewInstance("java.lang.ProcessBuilder", Array As Object(Commands))
    PB.RunMethod("redirectErrorStream", Array As Object(True))
    PB.RunMethod("start", Null)
End Sub

The only drawback is, that we have still to click "Clear" in the IDE Log Panel. But it works
