android - HandlerThread and Handler: how to use AudioRecord.setRecordPositionUpdateListener? -


i'm confused handler , handlerthread classes usage. reason i'm trying use them want utilize audiorecord class , setrecordpositionupdatelistener method (reference). methos description says:

use method receive audiorecord events in handler associated thread 1 in created audiotrack instance.

and that's want - setup audiorecord in main thread, receive data in working thread. figure need handlerthread i've created , started one. i've defined callback method implements audiorecord.onrecordpositionupdatelistener interface. want callback called worker handlerthread. don't understand how create handler pass setrecordpositionupdatelistener.

to associate handler thread, should create passing corresponding looper in constructor. so, if have handlerthread can done in following way:

looper looper = myhandlerthread.getlooper(); handler handler = new handler(looper);

and that's it, use handler in setrecordpositionupdatelistener method , callback executed @ worker thread. if need more explanation on handler, looper , handlerthread, can take here.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
