interruption

问题 Is it necessary for a thread in java to be in ready state before it gets interrupted by interrupt method? I tried to check this by typing the above given code below. class MyThread extends Thread { public void run() { try { for(int i =0;i<10;i++) { System.out.println("I am lazy thread"); Thread.sleep(2000); } } catch(InterruptedException e) { System.out.println("I got interrupted"); } } } public class SleepAndInterruptDemonstrationByDurga { public static void main(String[] args) { MyThread t=

问题 My App plays mp4 using AVPlayer, when my application finish launching, it interrupt the iPod music, although I have set the audio session to allow mix with others in - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { AudioSessionInitialize(NULL, NULL, NULL, NULL); AudioSessionSetActive(true); UInt32 sessionCategory = kAudioSessionCategory_AmbientSound; AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof

问题 I know that you can interrupt a thread created from say a runnable class, but how can I interrupt this thread I created from a method? Using a volatile boolean isn't working for me, so I assume either there is a better way to do this, or I need to somehow interrupt it. I don't want to interrupt all threads, just this one. I created a method that kicks off a Thread like this: public static void StartSyncThread() { new Thread() { public void run() { isRunning = true; // Set to true so while

问题 So in my app, running on iOS 6, everything seems to work fine with audio. I use the old C API format to catch interruptions using a callback; setting up via: AudioSessionInitialize(NULL, NULL, interruptionListenerCallback, (__bridge void *)self) and it was great. Using iOS 7 SDK though, it seems that my interruption callback is never called when the device receives calls or an alarm goes off. After some looking around, I heard that the old C api were deprecated and that you should move to the

问题 I am working with VOIP app. The app is working fine with CallKit. I am facing an issue if alarm fires within call. Every time when alarm stop firing (Audio Interruption ends), we are trying to setActive: on AVAudioSession. But it always gives an error with code 1701737535 ie. 'ent?'. The same error occurs when I am trying to initialize Audio Unit. Without using CallKit it's working fine. Anybody faced issue with activating Audio Session when Audio Interruption ends. I am getting different

问题 I'm working on a chat using assembly and i got this huge doubt, I'm currently using int 21, AH= 0Ah to get a string from the keyboard wich I will later send, char by char, through the serial port, but then i was wondering how, will I receive a msg from the other computer running the same program if this one is in a interruption waiting for me to input a string. How can i get around the fact that when inputing a string, the whole program is interrupted and anything being sent on the mean time

问题 Is it possible to create an interface that execute a main and the callbacks functions works as interruptions? I need an user interface that when the user push an on button the program starts to take images from a camera and then procesed them and show them on the interface. The program needs image changing on the user interface until the button on is pushed again and it interrupt the main programme that are catching and processing images Main function takes images from a camera and process

问题 I have this piece of code for executing three threads where the second thread should get interrupted on pressing enter and print the exit message: void input_val() { // DO STUFF return; } void process_val() { // DO STUFF try{ cout << "waiting for ENTER..." << endl; boost::this_thread::sleep(boost::posix_time::milliseconds(200)); } catch(boost::thread_interrupted&){ cout << "exit process thread" << endl; return; } return; } void output_val() { // DO STUFF } int main() { char key_pressed; boost

问题 synchronized (Foo.class) { while (someCondition) { try { Foo.class.wait(); } catch (InterruptedException e) { e.printStackTrace(); } } } It seems that this thread both wakes when some other thread call interrupt() or notify() on this thread. Are there any differences between the two? --EDIT-- I know one is for notifying an object, the other interrupts a thread. But both of these lead to the same consequence, that is, this thread is waken up, so what I want to ask is how these 2 situations'
