debugging

问题 I have some values in the local storage added in page A. When I go page B the local storage should not be cleared, but it is. This is a programmatic error. However, I cannot track it correctly to know when this happens. I tried just doing a setInterval to log in the console the value of my local storage each 1 second and I lose my values when I navigate out. I wonder if there is a way to detect or tool to determine in what moment I clear my local storage like a call stack more than tracing

问题 I ran into the following situation where I cannot debug the android app. I can run it but cannot debug it. I started brand new project copied everything and it worked (meaning was able to debug) but got this again. I tried both on emulator and my phone but no avail. I am using Android Studio 0.5.1 it fails at the very beginning. i don't feel like it has entered MainActivity. The moment app launches, I get "Unfortunately btbnie has stopped working" message. Appreciate any help/direction... 03

问题 I am trying to debug asp.net core internals to see what is going on under the hood. I set up .net core debugging in VS Code according to this article: https://github.com/OmniSharp/omnisharp-vscode/wiki/Debugging-into-the-.NET-Framework-itself Now I get .net core sources automatically while debugging and can step into methods, but not async ones . Since I have no source code at hand (it loads on the fly from somewhere) I cannot set a breakpoint in an async method to make debugger stop there. I

问题 I love Java 8 streams. They are intuitive, powerful and elegant. But they do have one major drawback IMO: they make debugging much harder (unless you can solve your problem by just debugging lambda expressions, which is answered here). Consider the following two equivalent fragments: int smallElementBitCount = intList.stream() .filter(n -> n < 50) .mapToInt(Integer::bitCount) .sum(); and int smallElementBitCount = 0; for (int n: intList) { if (n < 50) { smallElementBitCount += Integer

问题 I want to ask if there is a possibility to debug a release apk without having source code and how we can prevent user to do this action ? I thought that I can't debug an apk without a source code ( manifest has by default android:debuggable="false" ) until I sent it to a client and he asks me to disable debuggable mode because he got this issue . I try to reproduce the problem and I'm thinking if he did a reverse engineering. 回答1: You can debug an already signed APK with a number of different

问题 I have a bunch of NSLog statements in my code which I use for debugging. Every time I run my Project I'd like to start from a fresh console screen. Is there any command I can embed in my code which can do this? 回答1: Maybe you could use the "Auto Clear Debug Console" setting in the XCode Preferences.. Don't know if this answers your question? 回答2: When in the console(Debug mode) use Command + k to clear the console. 回答3: I think the only thing you can is for(int i= 0; i < 100; i++) NSLog(@" ")

问题 I am working on spring app and need to step through a controller method to see how it works. I am working in eclipse and building my app with gradle bootRun command.

问题 I have data on all the NCAA basketball games that have occurred since 2003. I am trying to implement a for loop that will calculate the average of a number of stats for each time at a point in time. Here is my for loop: library(data.table) roll_season_team_stats <- NULL for (i in 0:max(stats_DT$DayNum)) { stats <- stats_DT[DayNum < i] roll_stats <- dcast(stats_DT, TeamID+Season~.,fun=mean,na.rm=T,value.var = c('FGM', 'FGA', 'FGM3', 'FGA3', 'FTM', 'FTA', 'OR', 'DR', 'TO')) roll_stats$DayNum <-
