问题 After working a while with my Mediaplayer streamer project I got the Logcat saying: "Max cache size reached" every second. Is it normal? And should I do something about it?

I've also tryed this other command : Process process = Runtime.getRuntime().exec("/system/bin/logcat *:I"); but for some reason

问题 I just wanna to ask if it is possible to save android runtime error information in sdcard without device connected to PC? I tried to run: adb shell "logcat -v threadtime *:V > /mnt/sdcard/logcat_log.txt" which is lack of runtime error when I plug out the USB. Any thoughts? Thanks for your comments.

问题 I am trying to take logs (logcat and kmsg) via the following command "logcat -v time -f /dev/kmsg | cat /proc/" However I am not sure, where the log file is stored, and what will be its name.

Testbyte is as follows: byte testByte == 0; and updateAuto() is

问题 I am developing an application and during my testing on a real device I have found that it will crash and cause the phone to reboot (worrying I know...) Is there any way I retrieve the logcat from before the phone rebooted as the logcat seems to reset when the phone boots up. Thanks in advance. 回答1: Use http://code.google.com/p/acra/, which is a great lib to send crash reports to a google form incl. stack trace. I use it in my app and works nicely. Let me know if you have any difficulties
