Android Question Logcat not working

[Carl Peters]

I am recently new to b4a and trying to develop on a device i bought fairly cheaply on amazon however logcat does not work. It works fine on my emulated device, but not when i use b4a bridge. It doesnt show any logs, nor does it show activitycreate, pause or resume etc. I tried using Log Viewer v1.2 which again works fine for emulator but not for my device when i connect using b4a bridge.
My device I am using is on amazon:
7" inch Touch Screen Allwinner A13 1.0GHz CPU Android 4.0 Tablet PC 4GB HDD 512MB WiFi (Blue)
Model number Q8
Android version: 4.1.1
Kernel version: 3.0.8-InfoTMIC
jerry@ubuntu#1
Build number: JRO03H.eng.jerry.20131024.120002

I understand that occasionally the kernel can block logcat output? Is this my problem? Should I root my device and update the kernel to see if this helps? If so, could someone recommend a web page with a kernel that would work for my device to me as I have not done it before.
Many thanks

Are you testing it in Debug mode?

 

[Carl Peters]

yes i am. Debug(rapid)

Try to enable USB debugging and install Google USB driver. Connect to the device with USB debug mode. If the logs don't appear then the logs are disabled on your device.

Ok, great. It works when connected via usb cable, but not via b4a bridge. I get all the logs when connecting via usb only. Is this something I need to set up differently to get working with b4a bridge?

It should work automatically with B4A-Bridge. However only in debug mode.

The process is more complicated with B4A-Bridge as the logs are sent internally between the debugged app and B4A-Bridge.
