Let me describe my problem.
I have Android project which is under Continuous Integration (CI) server. In my case it is Jenkins.
Then I run my tests I just can see JUnit output in Jenkins console.
If some unexpected error happens I can’t see logcat from Android emulator.
Here I want to show you how I grab logcat from Android emulator. Now If something strange happens I can see logcat from emulator.
I made it using BASH script which is bellow. This script grab logcat and periodically check logcat filesize AND can create new file for logcat if it is greater than 5MB. Script can add time postfix to file if new one file was created.
PLEASE, TELL ME IF YOU KNOW THE BETTER SOLUTION !!!
HERE the BACH script:
#!/bin/sh LOGCATFILE=$1/logcat.out touch $LOGCATFILE adb -s $2 logcat -v time > $LOGCATFILE& PID=$! while true; do FILESIZE=$(stat -c%s "$LOGCATFILE") echo "Size of $LOGCATFILE = $FILESIZE bytes." echo "PID = $PID" if [ "$FILESIZE" -gt 5242880 ] then echo "$LOGCATFILE is too large = $FILESIZE bytes." now=$(date +"%Y_%m_%d_%H_%M_%S") NEWLOGFILENAME=/home/igor/logcat_$now.out cp $LOGCATFILE $NEWLOGFILENAME kill -9 $PID adb -s $2 logcat -v time > $LOGCATFILE& PID=$! fi sleep 10 done
To run just create file with executable permission and as parameter to script write path to dir with log
SECOND parameter is your device name which you can get when run adb devices in your terminal
igor@igor-laptop:~$ adb devices List of devices attached HT10WPL00853 device
The script parameters in my case will be next:
igor@igor-laptop:~$ ./write_logcat.sh ~/Temp HT10WPL00853
Hope, It help you!
