I am writing an app for which I need to embed HTML object in the Android app, I followed the tutorial given here: http://mobile.tutsplus.com/tutorials/android/android-sdk-embed-a-webview-with-the-webkit-engine/ and modified the code accordingly, following is the code, but I am getting a white screen...
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
WebView engine = (WebView) findViewById(R.id.web_engine);
engine.getSettings().setJavaScriptEnabled(true);
开发者_运维知识库 engine.getSettings().setPluginsEnabled(true);
engine.getSettings().setAppCacheEnabled(false);
engine.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
String data = "<html>" +
"<body>" +
"bb"+
"<object width=\"450\" height=\"300\" align=\"middle\"><param name=\"movie\" value=\"http://www.raaga.com/widgets/top10/widgettopten.swf?l=H&q=1\" /><param name=\"wmode\" value=\"transparent\"><embed src=\"http://www.raaga.com/widgets/top10/widgettopten.swf?l=H&q=1\" width=\"450\" height=\"300\" align=\"middle\" type=\"application/x-shockwave-flash\" wmode=\"transparent\" FlashVars=\"gig_lt=1312323434023&gig_pt=1312325057958&gig_g=2\"/> <param name=\"FlashVars\" value=\"gig_lt=1312323434023&gig_pt=1312325057958&gig_g=2\" /></object>"+
"gg"+
"</body>" +
"</html>";
engine.loadData(data, "text/html", "UTF-8");
}
}
The object that I want to embed is:
<object width="450" height="300" align="middle"><param name="movie" value="http://www.raaga.com/widgets/top10/widgettopten.swf?l=H&q=1" /><param name="wmode" value="transparent"><embed src="http://www.raaga.com/widgets/top10/widgettopten.swf?l=H&q=1" width="450" height="300" align="middle" type="application/x-shockwave-flash" wmode="transparent" FlashVars="gig_lt=1312323434023&gig_pt=1312326303531&gig_g=2"/> <param name="FlashVars" value="gig_lt=1312323434023&gig_pt=1312326303531&gig_g=2" /></object>
Put the file in the /assets directory, you can access it with the file:///android_asset/ directory.
Instead of putting the html in code the assets folder is where you can put static data files such as HTML and its related CSS, images, and JavaScript files, etc. Then you can use WebView.loadUrl(). This has the advantage of not having to be in code with Java String escapes and cumbersome editing. You will be able to create the file(s) separately, in your favorite web project editor, then copy and paste them. If you need to edit the file at runtime you can still load the file from the assets directory and still not have to worry about Java String escapes and cumbersome editing. Then apply the edits and pass to WebView.loadData().
To help debug this problem implement WebChromeClient.onLoadResource and check out the console message tutorial.
Don't forget to use PackageManager.getPackageInfo() to check if flash is available. If its not you can give the user the option to download it from the market.
Android has no official Flash viewer, so it doesn't know what to do with an embedded SWF.
If you put other (visible) HTML in your code, you should be able to see it in the view.
If you try to access your SWF through the webbrowser, you should get a broken/missing plugin icon.
Embedding HTML files is very simple, and loading it into WebView is even simpler. Here:
Create your HTML file, and put it in your project's assets file. in my case: "proj/assets/license.html"
WebView w = new WebView(this);
// Load the asset file by URL. Note the 3 slashes "file:///".
w.loadUrl("file:///android_asset/license.html");
That's it.
Did you declare the Internet permission in your Android manifest? In order to access the SWF which is on a remote server you will need that.
You need to enable plugins in your webview:
engine.getSettings().setPluginsEnabled(true);
