Android Application: Stop using Deprecated API's on new API level enabled device -


well started application support api level 8 i.e froyo verison. being on api level 18 jelly bean version, how stop using deprecated api's on application.
one example
dialog(api 1) vs dialogfragment(api 13)
following in mind
1)use android support library way go?
2)have runtime api level check below, healthy habit?

if (build.version.sdk_int==build.version_codes) {//some api level run code }else if(){ run code }


3) use reflection?
4)have separate code base each api level,makes no sense.
5)does palystore allows uplaod multiple apk's based on api level.or complete control on uses-sdk manifest value.

<uses-sdk android:minsdkversion="integer"       android:targetsdkversion="integer"       android:maxsdkversion="integer" />

what best way use latest api's 1 code base , make 1 apk , inturn have backward comparability support.

inputs appreciated.

one example dialog(api 1) vs dialogfragment(api 13)

dialog not deprecated. ways of using dialog may deprecated, such old-style managed dialogs.

use android support library way go?

generally, yes.

have runtime api level check below, healthy habit?

yes, though use >= or <=, not ==, drive behaviors range of api levels.

use reflection?

i wouldn't.

have separate code base each api level,makes no sense. palystore allows uplaod multiple apk's based on api level

in extreme cases may required. apps should not need this.

what best way use latest api's 1 code base , make 1 apk , inturn have backward comparability support.

that impossible answer in abstract.

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...

java.util.scanner - How to read and add only numbers to array from a text file -

i'm learning java , have question regarding reading file want read numbers file contains strings well. here example of file: 66.56 "3 java 3-43 5-42 2.1 1 and here coding: public class test { public static void main (string [] args){ if (0 < args.length) { file x = new file(args[0]); try{ scanner in = new scanner( new fileinputstream(x)); arraylist<double> test = new arraylist<>(); while(in.hasnext()){ if(in.hasnextdouble()){ double f=in.nextdouble(); test.add(f);} else {in.next();} } catch(ioexception e) { system.err.println("exception during reading: " + e); } } my problem add 66.56,2.1 , 1 doesn't add 3 after "3 or ignores 3-43 , 5-42 can tell me how skip strings , add doubles here? thanks all said 3 ie; "3, 3-43 , 4-42 strings either u read string , split , check number @ " , - or put in space between characters , integers. jvm after compilation tre...
