java - appView.addJavascriptInterface() does not work on API 17 -


i able use java function phonegap java script function , android 2.2 same code not run on api 17. should have call native java code on java script in api 17.

i use code in java file

 objcustomnativeaccess = new customnativeaccess(this, appview);             appview.addjavascriptinterface(objcustomnativeaccess,                     "customnativeaccess");     super.loadurl("file:///android_asset/www/index.html");

my customnativeaccess class is

public class customnativeaccess {         private webview mappview;         private droidgap mgap;          /**          * constructor          *           * @param gap          * @param view          */         public customnativeaccess(droidgap gap, webview view) {             mappview = view;             mgap = gap;         }          /**          * device phone number          *           * @return          */         public jsonobject login(string email, string password) {             jsonobject object = new jsonobject();                     object.put("login_status", login_status);             object.put("date", datestring);             return object;         }

and in java script use line call login function

 var value = window.customnativeaccess.login(email,pass);

so using call on api 2.2 when run code on api 17 give me error

uncaught typeerror: object [object object] has no method 'login' @ file:///android_asset/www/index.html:81

how can use on api 17

what have on api 17 annotate method @javascriptinterface:

public class customnativeaccess {    @javascriptinterface

and rid of constructor part:

/*private webview mappview;     private droidgap mgap;     public customnativeaccess(droidgap gap, webview view) {         mappview = view;         mgap = gap;     } */

also sure import javascriptinterface in project:

 import android.webkit.javascriptinterface;

you can read more here: http://developer.android.com/reference/android/webkit/webview.html#addjavascriptinterface%28java.lang.object,%20java.lang.string%29

edit: have annotate each method @javascriptinterface within class you'd access javascript.

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).
