Disable Logcat (DDMS) & Run Console automatically opening on any activity

阅读更多关于 Disable Logcat (DDMS) & Run Console automatically opening on any activity

问题 I monitor my logcat from outside Android Studio (logcat-color open beside my emulator on another screen/workspace) and would like to stop the Android DDMS view from opening within Android Studio automatically. It takes up screen real estate that I'd prefer to keep for my code. I know that I can remove the view entirely but I'd like to retain access to it for the times that I use it for linking directly to a problematic line of code quickly. I can filter the logcat output to only show 'error'

Can I see the Logcat on the Android Phone itself, without connecting it to the computer?

阅读更多关于 Can I see the Logcat on the Android Phone itself, without connecting it to the computer?

问题 If yes, then how? Does Logcat also log events like starting time of application on its own, or the application has to use something like Log.v(App_name,message) at the start of the application? 回答1: exactly Sashi : aLogCat is basical, but if you want your own reader, there is a special permission for this : Read_logs. The least you can see is an entry from the ActivityManager : looking like this approx. - Timestamp - INFO/ActivityManager(7703): Starting: Intent {act=android.intent.action.MAIN

Android studio logcat not working

阅读更多关于 Android studio logcat not working

问题 There is very awkward thing I am facing logcat is shown in debugging application but while running(not debugging) application it is not showing logcat . I tried restart it but nothing is happening. 回答1: In my case in Android 2.2, for some reason, Firebase was selected by default in the dropdown box marked above. So logs didn't drop. I just needed to change it to No Filters . Then it worked. I even tried restarting the logcat, that didn't work too. No Filters did the magic. Hope this helps

android.util.Log when publishing - what can I do / not do

阅读更多关于 android.util.Log when publishing - what can I do / not do

问题 I've got a hell of a lot of Log.i Log.d Log.e in my code for a recent app I've done. I'm about to publish this app and I don't really want people seeing it when they plug there phone into adb, but I do want it there for my own debugging. I was wanting to extend android.util.log and just have a boolean switch in there so I could just turn off the log when I publish and turn it on when developing but this class is final, am I missing a trick? I don't really want to go through my code an remove

问题 My project package doesn't show in DDMS > File Explorer (I had selected my phone in window devices). I found that an error is shown in logcat, which says can't open file for reading. Is it possible that I didn't install Eclipse properly? Before that, my project ran well and I could see the project path in the file explorer (under data>data>). After I had make few changes (I don't recall what changes I had made, too many), when doing another project, I uninstalled and reinstalled Eclipse, then
