android - onResume() is not called in physical device instead onCreate() is called -

-

iam little bit amazed this.i have onresume() in activity.its called , works in emulator, in physical device samsung galaxy note specific jellybean installed,its not called.instead oncreate() called time.why happens?

public void onresume(){     super.onresume();     if(firsttime){         try {             toast.maketext(getapplicationcontext(), "resuming activity",toast.length_long).show();             addreminder();         } catch(exception exception) {             exception.printstacktrace();         }     } else {         firsttime=true;     } }

this code.firsttime static boolean variable.it used prevent onresume() being called when app started first time

considering current scenario, should save variable in preferences instead of relying on activities lifecycle since lifecycle depends on many things. using static variable scenario bad choice in general.i think should solve problem.

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
