LogHelper (logcat)|生產應用線上App不用買-HotApp4Game

LogHelper is logcat reader that redirects the logcat output over UDP.

THIS IS A DEVELOPER TOOL! If You don't understand what this is for, do not even install it :-)

You NEED to have a data plan! It will use lot of bandwidth (depending on how much data your logs contain).

It doesn't care if You have WIFI or network connection. Both work.

Why the tool exists? I needed a way to check phone logs during testing in real life situations.

Perhaps a program I'm developing crashes during certain event, but I do not kno when or why, and once that happens out in the wild.

I also test on phones with no SDCard and limited storage. I can later filter the logs at the server side.

It reads phone logs (radio, events and/or main) asynchronously in the background as a service. Each read data is sent to a UDP port to a machine You set up.

Application can be set to run in the background, or just be running while application is running.

Application can also start on boot as well (only if installed on the device, doesn't work from SDCard).

Its read buffer can be tweaked from 128 to 9999 bytes. Though this setting is not enforced.

Program waits until input stream has this much data available and only then reads it. What ever obtained, will be sent (and that may be less bytes You wish for).

It can also be forced to flush the buffer every X seconds (but same effect is achieved with small buffer size).

On the server side You run:

nc -u -l 12345 #where 12345 is UDP port

socat -s -U STDOUT UDP-LISTEN:12345 >main.log &

Or use your favorite TCP/UDP listener (or write your own).

Oh, should You use TCP, I recommend to use socat only.

socat -s -U STDOUT TCP-LISTEN:12345 >main.log &
