android - Audio in webview continues to play in background -

-

i have webview audio player. if start audio , press return previous activity, audio still keeps playing in background. problem occurs when api lower 11.

my code: 

@override public void finish() {         if (android.os.build.version.sdk_int >= build.version_codes.honeycomb) {            webview.onpause();         } else {             webview.loadurl("about:blank");         } }

i tried 

webview.loaddata("", "text/html", "utf-8");

and

webview.clearcache(true); webview.clearhistory(); webview.destroy();

but didn't work.

does know how solve that?

this solves problem fro api > 11

@override public void onpause() {     super.onpause();     if(webview != null) {         webview.onpause();     } } @override public void onresume() {     super.onresume();      if (webview != null) {         webview.onresume();     } }

but lower versions (in case) need call onpause , onresume follows

    @override     public void onpause() {     super.onpause();     if(build.version.sdk_int >= build.version_codes.honeycomb){           webview.onpause();         } else {     try {         class.forname("android.webkit.webview")                 .getmethod("onpause", (class[]) null)                             .invoke(webview, (object[]) null);      } catch(classnotfoundexception cnfe) {         ...     } catch(nosuchmethodexception nsme) {         ...     } catch(invocationtargetexception ite) {         ...     } catch (illegalaccessexception iae) {         ...     }     }     }      @override     public void onresume() {     super.onpause();     if(build.version.sdk_int >= build.version_codes.honeycomb){           webview.onresume();         } else {     try {         class.forname("android.webkit.webview")                 .getmethod("onresume", (class[]) null)                             .invoke(webview, (object[]) null);      } catch(classnotfoundexception cnfe) {         ...     } catch(nosuchmethodexception nsme) {         ...     } catch(invocationtargetexception ite) {         ...     } catch (illegalaccessexception iae) {         ...     }     }     }
