java - Get Redirected URL From Browser - Android -


here's problem want authorize app user. api provides me oauth 2.0 process

i have link " " contains app key , redirection link

eg. http://www.apiprovider?api-key=my_api_key&redirect=redirect_link

link when opened in browser asks users username , password , authorizes app, after successful authorization user redirected redirect_link

the redirect_link encoded key need store in variable

eg. https://www.twitter.com/some_profile?key=asc545as454ds44as

i dont want user visit redirect link, want fetch url , close browser, the page should not open.

i have used code open link in browser

intent httpintent = new intent(intent.action_view);             httpintent.setdata(uri.parse("link_a"));             startactivity(httpintent);

if open page in webview, app can listen url change shouldoverrideurlloading() callback.

if prefer open stock browser, can start service periodically poll latest url:

string lastdate = "0"; … string newdate = long.tostring(calendar.getinstance().gettimeinmillis()); cursor cursor = context.getcontentresolver().query(     browser.bookmarks_uri,     browser.history_projection,     browser.bookmarkcolumns.date + " not null , " + browser.bookmarkcolumns.date + " > ?",     lastdate,     browser.bookmarkcolumns.date + " desc"); if (cursor.movetonext()) {     string url = cursor.getstring(browser.history_projection_url_index); } cursor.close();  lastdate = newdate; // update timestamp

when find url matches expected change, can switch activity , continue within context of app.

it possible close browser, may not polite, pov of end-user. imagine example has 5 open tabs important information, , destroyed!

note method can used chrome browser, different content provider: content://com.android.chrome.browser/bookmarks

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
