Hi all, I'm sorry to bother people with this (blame Google for not having documentation), but I have run into a snag whilst trying to invoke a method from javascript. I am loading my own html and all that, that's not the problem. JavaScript works fine, too, I have other scripts running perfectly (which do not require Java objects), so it is obviously in the way I am trying to call the methods (right?). The only example I have seen of this process uses something called a BrowserCallbackAdapter, which does not exist(?). At least, if it does, Google decided to mention a grand total of one times in the entire online reference, and only to say:
"Provides tools for browsing the web. The only classes or interfaces in this package intended for use by SDK developers are WebView, BroswerCallbackAdapter, BrowserCallback, and CookieManager." at http://developer.android.com/reference/android/webkit/package-descr.html which is all well and good except that that's it. All of it from everywhere. So DOES it exist? If it does, then what the hell am I supposed to take from that (incredibly information-devoid) blurb? How do I USE a "BroswerCallbackAdapter"(exactly as spelled at link, though I imagine that's a typo) and have success with the JavaScript to Java thing? Here is my code (without the apparently not-actually-real BrowserCallbackAdapter): MainActivity.java: Webview view; MediaPlayer.mp public void onCreate(blah){ blah blah blah... view=new WebView(this); view.getSettings().setJavaScriptEnabled(true); view.getSettings().setJavaScriptCanOpenWindowsAutomatically (false); view.getSettings().setPluginsEnabled(true); view.getSettings().setSupportMultipleWindows(false); view.getSettings().setSupportZoom(false); view.setVerticalScrollBarEnabled(true); view.loadUrl("file:///android_asset/first.html"); mp=MediaPlayer.create(this,R.raw.ring); view.addJavascriptInterface(mp, "mp"); first.html: /*I'm not bothering with head and body. The display works perfectly and I have other working JavaScript, so it's not a typo with any of that. The essentials are below*/ <script type="text/javascript"> function unhide(divID) { var item = document.getElementById(divID); if (item) { item.className=(item.className=='hidden')?'unh function playsound() { window.mp.start(); } </script> <input id="id" name="name" type="Button" value="カエル：" onClick="javascript:playsound();"/> I have tried my damndest to figure this one out by my lonesome, but I am at a complete loss. If anything I did is not correct, it is because there is no documentation findable by a single search engine in current existence or the 500 (almost literally) other combinations and variations of basically the same code didn't work either. I feel like there should be a way to do this, seeing as the online Android reference says it can, just not how exactly. Maybe it's a secret? Thank you so much to whoever the kind soul is that can alleviate this headache of mine. Seriously, thank you very much. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
