Logcat not displaying my log calls

由 点点圈 提交于 2019-11-27 00:10:45
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 this issue. What am I doing wrong? Am I even looking in the right place? I've tried using the DDMS and

由 喜你入骨 提交于 2019-11-26 17:29:13
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)? rudy s 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. Manoj Behera Check if you have hidden it... Use Alt + 6 to bring up the window and click on the button shown below 'Restore logcat view' You can show it pressing Alt+6 Or... Tools-> Android -> Android Device Monitor will open a separate window

Detailed debug logs with Volley

由 [亡魂溺海] 提交于 2019-11-26 16:51:49
问题 In Restkit on iOS there is a verbose debug option. RKLogConfigureByName("*", RKLogLevelTrace); . Does anyone know if there is an equivalent for Volley. Basically I am going straight to the ErrorListener but I get no additional info in LogCat. Both: VolleyLog.e("Error: ", error.toString()); And: VolleyLog.e("Error: ", error.getMessage()); Prints: 2.onErrorResponse: Error: 回答1: If you want verbose Log from the volley library, you have to use adb adb -s 42f63b0de7318fe1 shell setprop log.tag

Unexpected value from nativeGetEnabledTags: 0

由 て烟熏妆下的殇ゞ 提交于 2019-11-26 11:29:00
I installed the latest version of the SDK (r21) and ADT 21.0.0. I tried simple code, and it works well, but now I get a warning in LogCat that did not appear in the previous versions: Unexpected value from nativeGetEnabledTags: 0 I googled it, and I found Issue 39723: Emulator spams LogCat with "Unexpected value from nativeGetEnabledTags: 0" message . What does it mean? Hendrik I just ran into this problem, too. As a workaround I'm filtering the LogCat output with the following expression on the by Log Message field of the filter: ^(?!.*(nativeGetEnabledTags)).*$ Otherwise it is so spammed it

Disable LogCat Output COMPLETELY in release Android app?

由 守給你的承諾、 提交于 2019-11-26 08:57:48
问题 Shutting off my own app\'s LogCat output before releasing an app to the market is straightforward. I also know how to selectively filter LogCat message by tag and/or id for my own debug convenience. But now I am interested in something that may be much more difficult (perhaps impossible?): Disable all LogCat output, including & especially those coming from 3rd-party services like TtsService, GoogleLoginService, etc. Is this possible? To further clarify: I am not interested in filtering out

Filter output in logcat by tagname

由 醉酒当歌 提交于 2019-11-26 08:47:04
问题 I\'m trying to filter logcat output from a real device (not an emulator) by tag name but I get all the messages which is quite a spam. I just want to read messages from browser which should be something like \"browser: \" or \"webkit: \" , but it doesn\'t work... Here it is what I get: 回答1: use this: adb logcat -s "TAGNAME" 回答2: In case someone stumbles in on this like I did, you can filter on multiple tags by adding a comma in between, like so: adb logcat -s "browser","webkit" 回答3: Another

This question already has an answer here: The application may be doing too much work on its main thread 15 answers I installed the latest versions of SDK (API 16) and got the latest ADT. I'm now seeing these messages in the logcat, that I'm quite sure, I haven't seen before. Does anyone have an idea about this? 06-29 23:11:17.796: I/Choreographer(691): Skipped 647 frames!
