Android Studio - Can not open device monitor

爷,独闯天下 提交于 2019-12-05 10:15:10
I just downloaded Android Studio and it seems to import my existing Eclipse project well. However, if I try to open "Android Device Monitor" I get the message "An error has occurred" with a reference to a log file. My log file is included underneath. I am not sure why there is a reference to "Eclipse" int it? Anyhow, all in all, I have no idea where to go from here !SESSION 2015-01-05 04:00:15.329 ----------------------------------------------- eclipse.buildId=unknown java.version=1.8.0_25 java.vendor=Oracle Corporation BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=en_US Command

Java threads waiting to lock object that isn't (visibly) locked

Normally when I ask for a thread dump, the symptoms of a poorly performing system are easily explained; i.e. normally I would be able to see that a number of threads are clearly waiting on a monitor which has been acquired but not released by another. In this case, I have a lot of threads waiting for a monitor (0x965ad100), but none appears to have that monitor in the first place. The threads in question can be identified with this signature: waiting to lock <0x965ad100> (a uk.gov.dti.og.fox.ConAgent) I've tried Googling this, and all I seem to find are posts that discuss monitors that are

How to turn off particular monitor with .NET?

OK, I know there are quite a few posts on this topic. However, none of them provide the solution to my issue: I don't want just to turn off my monitor(s), I wish my code to turn off a specific monitor. The URL the most people refer to, http://fci-h.blogspot.com/2007/03/turn-off-your-monitor-via-code-c.html , doesn't help here, as it turns off all the displays. So, I have my laptop screen and an additional external monitor. While I'm watching movies, I switch the display to the external monitor and my laptop screen goes black, however, it's still on and glowing in the dark. I wish to turn it

Monitoring queries of a MySQL user

一世执手 提交于 2019-12-05 03:50:30
is there any way to monitor/log a MySQL user and the queries he/she has ran? I had to turn off the general log using the query: SET GLOBAL general_log = 'OFF'; because otherwise the log file was no more processable by text editors. I was looking for a way to turn this log on for some users I want to monitor, but it does not seem to work that way. Is there any other way to know everything a definite user does run on my database? Thanks in advance. There are a few ways I can suggest. SELECT * FROM information_schema.PROCESSLIST WHERE USER="someuser"; Now it is up to you what you use. Write a

Screen area vs Work area rectangle

Have a look at this API documentation page ... Can anyone explain to me the difference between the rcMonitor and rcWork components of the MONITORINFO structure? Although I'm happy with the idea that a window has areas you can't work with (like the caption for instance), I don't really see how this applies to monitors... All contributions gratefully received... Martin rcMonitor is the total resolution of the display rcWork is the max area you can use,eg if you went fullscreen maximized a window The work area is the portion of the screen not obscured by the system taskbar or by application

How can I force display detection in Windows?

I often boot my Windows 7 PC with the attached KVM switch focused on another computer. When I switch to the booted PC, the display resolution is wrong (and the second attached monitor is not detected). I can correct this by right-clicking the desktop, choosing Screen Resolution and clicking Detect . This makes Windows detect attached displays and adjust to the most optimal resolution. I would like to write a small utility to do this automatically. Which Win32 API call or C# object should I use? You can try: You can use Spy++ to search for the windows that are open and take a look at their

How to know child process status and resource usage on windows?

自作多情 提交于 2019-12-05 01:04:28
问题 I want to write a program, which will launch a child process. The child process may be windows mode or console mode program. I want to monitor the child process status and resource usage. e.g. I want to know the child process is still running or terminated. If it terminated, I want to know the reason (is terminated normally or because of crash?). And during the child process running and/or it terminated, I want to know its resource usage, especially CPU time (user time, system) and memory

Creating a virtual monitor (the display device)

问题 I raised a question here but realized I was going the wrong direction. I need to create a virtual monitor (really just the space in memory) that is large enough to fit a website, that would normally span several screens. Is this possible in any language? I tried Java, but failed miserably so far. I don't expect this to be easy, any pointers would appreciated. I'd imagine the OS and the video cart would have to told in somehow that there's a third monitor. 回答1: Use any Virtualization tool

How to monitor my network connection with Java?

Is there any sample code that can report the url that my PC is connecting with Java? While I use my browser to connect to different sites and watch video online, it should capture the urls. Is it doable in Java? I don't want detailed traffic, just record the urls. The fastest way is probably going to be to capture the output of the command-line tshark program (for at least windows and linux). This works on my linux box: sudo tshark -f 'port 80' -R 'http' -V | grep -A 1 '^Hypertext Transfer Protocol' And produces output like: Running as user "root" and group "root". This could be dangerous.

Python watchdog for another Python process technique?

I have a realtime data grabber that runs indefinitely, grabbing data over HTTP and putting it in a MySQL database every few seconds. In my program, I have a while True loop that spawns workers (functions that download the data and save it) whenever the last spawned time is greater than X seconds: while True: if _last_updated - datetime.now() > timedelta(seconds=5): green_pool.spawn_n(worker) # yes I'm using Eventlet! _last_updated = datetime.now() What would be the best way to ensure that this module always does work, never freezes and is never down? Should I be checking the green pool size? I
