Android arduino communication via usb using adk mode -


i working on android , arduino application uses adk mode communication have implemented runnable in main activity , in run method of reading values , when reading finishes writing values arduino board , communication running infinite.i using handler updating gui application stops it's communication after sometime not able figure out problem? gui update in handler takes more time happening or else?

following code receiving , sending data:

 while (true) { // read data     try {     int ret_read = 0;     byte[] buffer_read = new byte[128];     ret_read = minputstream.read(buffer_read);      (int p = 0; p < 2 * (nooffsensors); p = p + 2) {     intlistvalues.add((int) composeint(buffer_read[p],                 buffer_read[p + 1]));      log.d("jankari", "pu value : "+string.valueof((int) composeint(buffer_read[p],                 buffer_read[p + 1])));      }         message mpu = message.obtain(mhandlerpusensors);       mpu.obj = new valuemsgpusensors("f", ret_read,intlistfvalues);         mhandlerpusensors.sendmessage(mpu);      (int = 0; < 2 * (noofansensors); = + 2) {     intlistanvalues.add((int) (composeint(buffer_read[2* (nooffsensors) + a],                  buffer_read[2* (nooffsensors) + + 1])));     log.d("jankari", "an value : "+string.valueof(          (int) (composeint(buffer_read[2* (nooffsensors) + a],      buffer_read[2* (nooffsensors) + + 1]))));      }     message man = message.obtain(mhandleransensors);     man.obj = new valuemsgansensors("f", ret_read,     intlistanvalues);     mhandleransensors.sendmessage(man);      (int l = 0; l < noofsw; l++) {     intlistswvalues.add((int) buffer_read[2* (nooffsensors) +         2 * (noofansensors) + l]);     log.d("jankari", "sw : "+string.valueof((int)           buffer_read[2* (nooffsensors) + 2 * (noofansensors) + l]) );     }     message msw = message.obtain(mhandlerswsensors);     msw.obj = new valuemsgswsensors("f", ret_read,intlistswvalues);     mhandlerswsensors.sendmessage(msw);          += 1;       minputstream.close();      // send output arduino     sendoutput();        } catch (ioexception e) {       break;     }  }

and handlers using are,

handler mhandlerpusensors = new handler() {         @override     public void handlemessage(message msg) {         valuemsgpusensors msgpu = (valuemsgpusensors) msg.obj;         txtreceivedbytes.settext("received bytes: " + msgpu.getret());         (int = 0; < txtlistfsensors.size(); i++) {             txtlistfsensors.get(i).settext(string.valueof(msgpu.getfreadings().get(i)));         }         intlistfvalues.clear();              } };

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)...

c++ - End of file on pipe magic during open -

i have c++ application in starting process(wireshark) following. if (fp == null){ fp = popen(processpath, "r"); //processpath process want start if (!fp){ throw std::invalid_argument("cannot start process"); } fprintf(fp, d_msg);//d_msg input want provide process } else if(fp != null){ fprintf(fp, d_msg); } the problem when execute c++ application, start wireshark error end of file on pipe magic during open what should avoid that? also tried using mkfifo create named pipe , execute it. used this: if (fp == null){ system("mkfifo /tmp/mine.pcap"); fp = popen("wireshark -k -i /tmp/mine.pcap", "r"); if (!fp){ dout << "cannot start wireshark"<<std::endl; throw std::invalid_argument("cannot start wireshark"); } input = fopen("/tmp/mine.pcap", "wb"); fprintf(input , d_msg); fclose(input)...
