android - how to change image background via any file explorer -

-

i trying understand how change background image of application (not via eclipse) using file explorer in android(phone) , picking file.png saved background image in app

following comments above:

well, thing can think of (if understand correctly, want change background of application, via application - right?) set background theme.wallpaper. in other application, can set background differently , in base application, bg changed accordingly.

asuming - pick file explorer, navigate .jpg, .png etc. file , set device's background. if application uses theme.wallpaper default application theme, changed, according background image you've set device.

in simpler terms: 1. problem - want change background of application (yapp short), want achieve choosing picture application (let's gallery). 2. solution - thing can think of set desired image background device itself. in yapp you'll have theme.wallpaper set, use device's background

to put code, here's sample extraction androidmanifest:

<activity android:name="mainactivity" android:theme="@style/theme.translucent"> </activity>

this applied activity. here's link reference.

cheers

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...
