How to get Verbose logging in logcat for a specific module

由 青春壹個敷衍的年華 提交于 2019-12-06 18:36:32
问题 One of the android Modules (AudioFlinger) has support for verbose logging (with Tag=AudioFlinger). Question is how can I see those logs in the logcat? I did the setprop log.tag.AudioFlinger VERBOSE - but it doesn't seem to work. Do I need to change something and then rebuild the android source again? 回答1: The logcat documentation doesn't really help. But with more digging I was able to find the answer, as I was expecting the VERBOSE logging is by default OFF at compile time. Looking at the

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. Here some information I just digged. From the very beginning, I though this command 'adb shell "logcat -v threadtime -f /mnt/sdcard/logcat_log.txt"' will output logs into the file 'logcat_log.txt' continuelly. After several times of testing, checking and document reading about logcat, I have found

Android logcat logging only info level on real device. Cannot get debug messages, not even unhandled exceptions

由 旧巷老猫 提交于 2019-12-06 00:29:48
问题 I am developing for android for some time, and so far I didnt have any problem with logcat. Until now, i have new phone for development, Huawei Y300 (Y300-0100) and in logcat there is no messages from DEBUG level. This is problem, because I don't get Exceptions stack trace prints. I have to use emulator for that, you understand that it is annoying.. So far i figured out this: from: Log.v("TEST VERBOSE", "verbose level"); Log.d("TEST DEBUG", "debug level"); Log.i("TEST INFO", "info level");

How to highlight filter/search hits in Android Studio Logcat

由 孤人 提交于 2019-12-05 16:34:49
I filter my Logcat lines based on a single String, as depicted below: But there I face numerous long long lines and I have much trouble recognizing the wanted values in the middle of the lines. For example, in the above picture, it would be to much convenience to see all "Aggregate" keywords highlighted. Is there any way to highlight the filter/search hits on the Logcat console? From what I see, you use the "Filter", that will show all only lines with word matches to your filter. If you want to search inside the filter results and get highlighted text matches, click on Cmd+s (on Mac) or Ctrl+s

And so all the internal actions are getting logged and the error message disappears very quickly. You should try the following (it worked for me) Restart
