Development process and API levels
I haven't really explored lint but could that help point out any possible issues. It will. Lint will report to you anything that you use that is newer than your android:minSdkVersion but is acceptable to your build target. Lint will generally report this automatically for Eclipse, though you may want to run Lint manually from time to time, as sometimes it seems to miss some stuff. Lint is also available for command-line builds, and I presume that it is (or will be) integrated into Android Studio. You can read more about Lint in the developer documentation.

how to implement thread process in phonegap development?
JavaScript in the WebView does not run on the UI thread. It runs on the WebCore thread. The execute method also runs on the WebCore thread. If you need to interact with the UI, you should use the following: @Override public boolean execute(String action, JSONArray args, final CallbackContext callbackContext) throws JSONException { if ("beep".equals(action)) { final long duration = args.getLong(0); cordova.getActivity().runOnUiThread(new Runnable() { public void run() { ... callbackContext.success(); // Thread-safe. } }); return true; } return false; } If you do not need to run on the UI thread, but do not want to block the WebCore thread: @Override public boolean execute(String action,

cross memory attach. How do I get the remote address from a child process to a parent process
The system calls process_vm_readv and process_vm_writev are meant for fast data transfer between processes. They are supposed to be used in addition to some traditional way of interprocess communication. For example, you may use a regular pipe or fifo to transfer the required addresses between your processes. Then you may use those addresses to establish faster process_vm_ communication. The simpliest way to transfer something between forked processes should be the pipe() function (man 2 pipe has a good example of its usage). There are many other ways to do so of course, like using sockets or messages. You can even write an address to a file and let the other process read it.

Symfony2 Process component - unable to create pipe and launch a new process
The file handles are not being garbage collected, so they eventually fill up (os limit or php limit, not sure), but you can fix it by adding an explicit garbage collection call: gc_collect_cycles(); usleep($sleep * 1000000); Also, be forwarned that garbage collection doesn't work very well inside a foreach loop because of the way that php maps the temporary $foo as $bar => $var array variables into memory. If you need it in that part of the code you could switch it to something like this instead, which I think should allow for garbage collection inside the for loop: $processes[] = new Process("ls > /dev/null", null, null, null, 2); $processes[] = new Process("date > /dev/null", null, null, null, 2); $sleep = 0; do { $count = count($processes); for($i = 0; $i < $co

Node.js Detached child process is invoked as interactive foreground process

In Java What is the exit value of a process which is killed in the background through Linux shell using process id
This is not a Java specific question. The return code will be the same for all Unix systems here (at least I have never seen a Unix system not behaving this way): 128 + the number of the signal which caused the process to terminate. No idea for Windows... Therefore, 130 in your case. In C, you'd check (after a call to waitpid() for instance) whether a process has been terminated by a signal using WIFSIGNALED(status).

Is a multi process Java program a single process in the context of the actual machine underneath the JVM it is running on?
You're confused between processes and processors. A JVM counts as a single process on your machine, yes. When you start the JVM it runs as a program and it executes Java byte code. A JVM can address all the processors on you machine. When you start a Thread in Java it executes on an available processor.

Error "The process cannot access....becuse it is being used by another process. " in Delete Image

You should: Only call Image.FromFile once and reuse the object in Setimage (you're loading it twice in a single if condition...) Dispose of every Image when you're done with it Dispose of the old BackgroundImage before you set the new one So long as you dispose of every Image which is related to the file before you delete the file, you should be okay.

Is it possible to use "kill" to send a signal to a process without forcing the process to exit?
According to the man pages for kill and signal(7), the best you could hope for would be to stop and then maybe continue. But I don't think that will do what you want. I also question the desire to use "kill", a command whose name makes its intended purpose very clear, to do this. Almost every signal you can send with kill is intended to terminate a process or cause it to dump core. I'm not an expert but I think you are trying to use the wrong tool here.

how to run back-end (Non-Stop process) process without affect the Ui Thread in Android
@forgivegod is right (about the service), that will get you in the background.

System.IO.IOException: The process cannot access the file because it is being used by another process
Short answer: Try Thread.Sleep(100) before you read and then read as fast as you can. I thought that by setting the FileAccess.Read I should be able to always read the file? By setting FileAccess.Read you are just saying that you need to read from the file. By setting FileShare.ReadWrite you are saying you are comfortable with the 3rd party reading and writing to the file while you read it. The exception means that the 3rd party is not comfortable with you reading while they are writing. Your first bet is to check if you can configure the 3rd party process to allow other processes to read while they write, but be aware that reading from a file that is being written to can be troublesome. How can I make sure that this doesn't cause an exception, or do I need to just loop around un

signal handling when process is waiting for another process to terminate
The kernel doesn't really care that process-1 is "waiting for process-2 to finish" (in particular it's not interested in "why" it's in the state it is, merely that it is in some state: in this case, idling in the kernel waiting for some event). For typical1 caught signals, the signal-sender essentially just sets some bit(s) in the signal-receiver's process/thread state, and then if appropriate, schedules that process/thread to run so that it can see those bits. If the receiver is idling in the kernel waiting for some event, that's one of the "schedule to run" cases. (Other common situations include: the receiver is in STOP state, where it stays stopped except for SIGCONT signals; or, the receiver is running in user mode, where it is set up to transition to kernel mode so as to notice th

How does process blocking apply to a multi-threaded process?
Let's say you have a work queue where the UI thread schedules work to be done and the IO thread looks there for work to do. The work queue itself is data that is read and modified from both threads, therefor you must synchronize access somehow or race conditions result. The naive approach is to synchronize access to the queue using a lock (aka critical section). If the IO thread acquires the lock and then blocks, the UI thread will only remain responsive until it decides it needs to schedule work and tries to acquire the lock. A better approach is to use a lock-free queue about which much has been written and you can easily search for more info. But to answer your question, yes, it is still much easier than you might think to cause UI to stutter / hang even when using multiple th

Can we dynamically create a process and maintain a process pool?
If what you need is to monitor the child processes and spawn them when they go down, then this approach may be helpful. Make the parent process to wait for changes in child using waitpid in a loop. Maintain a counter at parent to track number of processes alive. Based on your requirement, you can create one or more new child process using fork call and update the counter. Man of fork is here. Similar question to track the death of child is here.

Sometimes StartWithCreateProcess sets the 0x8000000 (CREATE_NO_WINDOW) (if the CreateNoWindow parameter is set) and the 0x400 (CREATE_UNICODE_ENVIRONMENT) (if the system is NT based) flags, but that's all.

Getting Windows error 32 process can not access file it is used by another process
Something is holding a reference to the file you try to move. Place a try/except block around the shutil.rename and print out which file causes the problem. When you find out which file causes the problem find out who is holding a reference to it. One way to find who is holding a reference to a file is either using Process Explorer or Unlocker Update: I took a look at the code of the ID3 library and it seems that, if you pass in a filename, it doesn't close the file, EVER :D You should do something like: with open(filename, 'rb') as f: tags = ID3(f) # do your stuff shutil.rename(filename, ...)

IOException The process cannot access the file because it is being used by another process when using XDocument
You can still use XDocument and an XmlReader: XDocument doc; using (var reader = XmlReader.Create("C:/Trio Scripts/example.xml")) { doc = XDocument.Load(reader); } When the using block completes for the reader, then the file handle should be closed. Update: Maybe the behavior of XmlReader.Create(string) doesn't open the file in the most minimal fashion. In case that's what's causing the exception, try this more explicit code specifying file permissions: XDocument doc; using (var stream = File.Open("C:/Trio Scripts/example.xml", FileMode.Open, FileAccess.Read, FileShare.ReadWrite)) using (var reader = XmlReader.Create(stream)) { doc = XDocument.Load(reader); }
