android - Determining MIME type of shared Dropbox intent? -

-

my app receive share requests other apps including dropbox. need know kind of file receiving, mime type dropbox "text/plain". example:

intent = getintent(); string smimetype = i.gettype();  //value = "text/plain" string sextratext = i.getstringextra(intent.extra_text);   //value = "http://db.tt/th42k3b7"

i need know difference between images, videos , music files. there way determine file type based on information in intent? or there way use dropbox api this?

thanks, -gregg reno

edit: based on proposed solution smarx, found android code here: android - detect url mime type?. added this:

slocation = connection.getheaderfield("location"); mimetype = urlconnection.guesscontenttypefromname(slocation);

i'm not sure norm here, think text/plain refers type of data being shared in intent. (because it's url, plain text seems appropriate.)

from url, can find mime type issuing head request. first resolve shortened link full share link (in location header). convert share link direct link content replacing www.dropbox.com dl.dropboxusercontent.com. (see https://www.dropbox.com/help/201.) issue head request , take @ content-type header:

$ http head http://db.tt/th42k3b7 http/1.1 302 found connection: keep-alive content-type: text/html; charset=utf-8 date: mon, 26 aug 2013 15:12:32 gmt server: nginx cache-control: no-cache location: https://www.dropbox.com/s/dmbdlf56t043miq/2012-02-11%2019.56.17.jpg pragma: no-cache  $ http head https://dl.dropboxusercontent.com/s/dmbdlf56t043miq/2012-02-11%2019.56.17.jpg http/1.1 200 ok connection: keep-alive content-type: image/jpeg content-length: 1560063 date: mon, 26 aug 2013 15:12:52 gmt server: nginx x-requestid: a2c4d393af5e0eee80d6f33f68762fd4 accept-ranges: bytes cache-control: max-age=0 etag: 1525n pragma: public x-dropbox-request-id: 23f50be73831cde4f39a12d5e3f0af78 x-server-response-time: 1149

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...
