Eclipse LogCat - Not Working

阅读更多关于 Eclipse LogCat - Not Working

问题 This is the most frustrating thing ever, LogCat keeps deactivating/disconnecting. After running eclipse, LogCat logs for first run and after that, it goes Blank. I have to restart Eclipse to get it running again, and then same thing happens again. What is matter with it? It used to work fine. I can't recall changes I've made to undo what I (might) have done. EDIT - Screen of Eclipse as requested. EDIT 2 - Screen of currently installed SDK packages 回答1: If the LogCat is empty, the emulator

Android adb logcat time filter

阅读更多关于 Android adb logcat time filter

Does anyone know how to filter out the logcat ('adb shell logcat') so that it only shows the log statements after current date and time ? Thanks in advance. Activities created after the current date and time? Or just log statements after the current time? Could it be as simple as "adb logcat -c; adb logcat" Neuron use adb logcat -t "01-21 10:10:10.000" this will give you log after 21st January 10.10.10.000 Before you start up logcat first pass it the argument -c In the terminal you would say adb logcat -c adb logcat This would produce a fresh log. 来源： https://stackoverflow.com/questions

Logcat empty using ACRA on device

阅读更多关于 Logcat empty using ACRA on device

问题 So I'm using ACRA 4.4.0 with all defaults, and my logcat field is empty. My app has the <uses-permission android:name="android.permission.READ_LOGS" /> permissions, which should at least give me my own app logs since Jelly Bean. Final note: READ_LOG permission is not granted to third-party apps anymore since Android 4.1 (JellyBean). Starting with this version, logcat provides only traces from your own app , without requiring a permission. JellyBean logcat logs are retrieved by ACRA starting

Observe very long String content in Eclipse

阅读更多关于 Observe very long String content in Eclipse

问题 Since LogCat truncates long strings, I work around this using FileOutputStream to inspect the contents of very long strings. It works but it forces me to 'adb pull' that file, which is not very convenient, compare to watching it on LogCat. Is there any other way in Eclipse to watch very long strings? 回答1: For the record, the answer was found here. 回答2: when you stop in debug on the variable do the following and past it to a text file 回答3: I think it will be easier to use the eclipse debugging

阅读更多关于 How do I stop eclipse from auto creating filters for android logcat?

问题 After an update my eclipse started to create filters automatically for LogCat. I don't really mind if it creats those useless filters, but it always auto-select the one I least want to look at. Is there a way to disable this auto-filter feature? 回答1: Try disabling: Window -> Preferences -> Android -> Logcat -> Display logcat view when there are messages from an app in workspace (as it was described in this issue in Android bug tracker: http://code.google.com/p/android/issues/detail?id=20965)
