Android asynctask waiting for anotherr asynctask - 


  public class getflyers extends asynctask<string, void, bitmap> { imageview imageview; int imagesize; context context; string url=""; string im=""; flyer fly; imagefragment i1; int position; public getflyers(imageview imageview, int imagesize, context conext,string im, flyer flu, imagefragment i1, int position ) {     this.im = im;     this.position = position;     this.imageview = imageview;     this.imagesize = imagesize;     this.context=context;     this.i1 = i1;     fly = flu; } protected bitmap doinbackground(string... urls) {     bitmap map = null;     (string url : urls) {         log.d("firste","image loaded back");         if(url != null && !url.trim().equals(""))         {             map = downloadimage(url);             this.url = url;         }     }     return map; } @override protected void onpostexecute(bitmap result) {   } private bitmap downloadimage(string url) {     bitmap bitmap = null;     inputstream stream = null;     bitmapfactory.options bmoptions = new bitmapfactory.options();     bmoptions.insamplesize = 1;     try {         stream = gethttpconnection(url);         bitmap = bitmapfactory.                 decodestream(stream, null, bmoptions);     } catch (ioexception e1) {         e1.printstacktrace();     }         {         try         {             stream.close();         }         catch(exception e)         { 
        }     }      return bitmap; } // makes httpurlconnection , returns inputstream private inputstream gethttpconnection(string urlstring)         throws ioexception {     inputstream stream = null;     url url = new url(urlstring);     urlconnection connection = url.openconnection();     try {         httpurlconnection httpconnection = (httpurlconnection) connection;         httpconnection.setrequestmethod("get");         httpconnection.connect();         if (httpconnection.getresponsecode() == httpurlconnection.http_ok) {             stream = httpconnection.getinputstream();         }     } catch (exception ex) {         ex.printstacktrace();     }     return stream; }

}

i have code, whenever called thread... lets 3 times.. getflyers task = new getflyers tasl.execute ... unfortunately 1 call per time moves on. 1 asynctask goes..i want run asynctask while running this

asynctasks executed serially default starting honeycomb.

to run asynctasks in parallel on platrorms, run as

if (build.version.sdk_int >= build.version_codes.honeycomb) {     task.executeonexecutor(asynctask.thread_pool_executor); } else {     task.execute(); }

see

asynctask: order of execution

asynctask.executeonexecutor(executor, params)

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
