i have never seen this error while programming, the error is mostly, when i start my app first in the morning. Is it possible, to read this log file later or should this error happen for diagnosis, when i am in B4A?
The logs are kept in a circular buffer. You can browse previous entries in the logs however you will usually only be able to go back a couple of minutes.
There are however several log viewers apps that will allow you to email yourself the logs from the device.
