android-logcat

问题 I'm a total noob at Android programming, and wanted to learn how to debug my apps. I can't seem to have my Log.i|d|v calls displayed in the LogCat. Here's the code that I'm using. As you can see I have defined a LOG_TAG constant, but can't seem to find it in the LogCat. I have also imported android.util.Log AND I have made sure that in my AndroidManifest I have "debuggable" set to TRUE. I have also checked http://developer.android.com/reference/android/util/Log.html w/o any luck resolving

问题 I have recently started to use Android Studio v0.1.1, And i can't seem to find LogCat... Is it gone? Or if not, how can I enable it? If it is gone, is there any way to enable something similar to log my app behavior (and mainly crashes)? 回答1: I think I still can find logcat in my installation of 0.1.1 Try pressing Alt + 6 on Windows or CMD + 6 on Mac. 回答2: Check if you have hidden it... Use Alt + 6 to bring up the window and click on the button shown below 'Restore logcat view' 回答3: You can

问题 e.printStackTrace() works fine (i.e. prints my stacktrace to stderr) but Log.X fails to print a stacktrace at all. For example: } catch (IOException e) { Log.e("Network", "Exception", e); e.printStackTrace(); } Output: 08-31 03:46:21.992: W/Network(13238): Exception 08-31 03:46:22.092: W/System.err(13238): java.net.UnknownHostException: Unable to resolve host "...": No address associated with hostname 08-31 03:46:22.204: W/System.err(13238): at java.net.InetAddress.lookupHostByName

问题 The title speak for itself, but I would add some pointers I've noticed along the way. I would like anyone which also experience the end result while developing for Android to try to reproduce this and see if this scenario is really the case, and if someone have a solution, that would make me very happy :), it is extremely frustrating that I need to hard reboot my computer while developing... The crash happens when Logcat is over populated. By over populated I mean that from a point in time,

问题 I have an error on my Android Application and one of the really annoying things that LogCat does is write exception Caused at android. at android... at android... at android... and 21 more I need to read the error inside that 21 more. Is there a way to do it?

Then when you're there, you have full access

I'm testing my application in 2 devices: HTC EVO 3D HTC DESIRE. At one point I noticed something strange: when I'm testing on EVO 3D I saw that I'm getting all packets of data stream twice, which is really strange because server cannot send me one packet two times. I thought it's because of EVO's dual core
