Battled this one as well. Found the answer [here][1].

Looks like you were dead on with `android:scrollbarStyle=&quot;insideOverlay&quot;`, except that because of some bug it doesn&#39;t function right when defined in XML. It works right if you use:

    webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);

Annoying.

    public void setVerticalScrollbarOverlay (boolean overlay)

Since: API Level 1  
Specify whether the vertical scrollbar has overlay style.  
Parameters  
overlay TRUE if vertical scrollbar should have overlay style.


I&#39;m running Mac OSX 10.6.4 and have installed RVM.  Its been great so far, I really love the way it lets me manage having multiple versions of rails and ruby on the same machine without headaches!

However, I don&#39;t want to have to install certain gems (such as passenger) for each setup. Is there a way to share gems between gemsets?  I have a 1.8.7@rails2.3.8 and 1.9.2@rails3, can I have gems such as passenger, mysql, and capistrano installed once and used with all versions?

How do I use RVM and create globally available gems?

I need help checking whether a device has a sim card programatically. Please provide sample code.

How can I check whether the Sim Card is available in an android device?

In my `WebView`, I have some block elements that have a background color (different than white). However, the background color does not go *all the way across the sky*.. um, screen. Instead, it leaves a small white strip to the right, for where the scrollbar would go. Now, I want the scrollbars to appear only when scrolling (and fade away once the user has finished scrolling). I tried:

    android:fadingEdge=&quot;vertical|horizontal&quot;
    android:fadeScrollbars=&quot;true&quot;
    android:scrollbarStyle=&quot;insideOverlay&quot; (and all other options)

Also, my HTML contains the following in `&lt;head&gt;`:

    &lt;meta name=&quot;viewport&quot; content=&quot;target-densitydpi=device-dpi&quot; /&gt;

So that it doesn&#39;t allow zooming and doesn&#39;t zoom out by default.

However, I can&#39;t figure out how to get rid of the white strip. Any ideas?

Android WebView leaves space for scrollbar

In my <code>WebView</code>, I have some block elements that have a background color (different than white). However, the background color does not go all the way across the sky.. um, screen. Instead, it leaves a small white strip to the right, for where the scrollbar would go. Now, I want the scrollbars to appear only when scrolling (and fade away once the user has finished scrolling). I tried:
<pre><code class="hljs language-ini">android:fadingEdge="vertical|horizontal"
android:fadeScrollbars="true"
android:scrollbarStyle="insideOverlay" (and all other options)
</code></pre>
Also, my HTML contains the following in <code>&#x3C;head></code>:
<pre><code class="hljs language-ini">&#x3C;meta name="viewport" content="target-densitydpi=device-dpi" />
</code></pre>
So that it doesn't allow zooming and doesn't zoom out by default.
However, I can't figure out how to get rid of the white strip. Any ideas?

Under `DDMS`, there is a `HEAP` tab, and then I click my android application under &#39;Devices&#39;. 
But it said:

    Heap updates are NOT ENABLED for this client

How can I enable Heap update for my android application?

I have a multi-line `TextView` that has `android:ellipsize=&quot;end&quot;` set. I would like to know, however, if the string I place in there is actually too long (so that I may make sure the full string is shown elsewhere on the page).

I could use `TextView.length()` and find about what the approximate length of string will fit, but since it&#39;s multiple lines, the `TextView` handles when to wrap, so this won&#39;t always work.

Any ideas?

How do I tell if my textview has been ellipsized?

I have written a service with a remote interface and installed it on my PC&#39;s Eclipse AVD. I have a client test harness which starts and invokes methods in the service. Initially I had the service installed by a control class and activity, which I have now removed, so that the manifest for the service looks like:

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;manifest
    xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
    package=&quot;com.myname.gridservice&quot;
    android:versionCode=&quot;1&quot;
    android:versionName=&quot;1.0&quot;&gt;
    &lt;application
        android:icon=&quot;@drawable/icon&quot;
        android:label=&quot;@string/app_name&quot;
        android:debuggable=&quot;true&quot;&gt;
        &lt;service
            android:enabled=&quot;true&quot;
            android:debuggable=&quot;true&quot;
            android:name=&quot;OverlayService&quot;&gt;
            &lt;intent-filter&gt;
                &lt;action android:name=&quot;com.myname.OverlayService.SERVICE&quot;/&gt;
                &lt;action	android:name=&quot;com.myname.gridservice.IRemoteInterface&quot; /&gt;
            &lt;/intent-filter&gt;
        &lt;/service&gt;
     &lt;/application&gt;  
    &lt;/manifest&gt;   
 

so there&#39;s no activity tag.  

When I launch it from the debug icon in Eclipse, the console tells me that it&#39;s installing the apk (which it is), but it does not appear as a debug thread and breakpoints aren&#39;t triggered, although the service&#39;s behaviour is OK as far as the client sees it. If I wrap the service tag in an activity tag which has an associated class and launch that, then I can debug it.

Is it possible to debug the service without wrapping it in an activity?

I am trying to develop an app on canvas,I am drawing a bitmap on the canvas. After drawing, I am trying to convert into bitmap image.

Can anyone give me a suggestion?

converting a canvas into bitmap image in android

I did try samples, demos from Google codes and other resources with `WebView`, but when i try to do it in my own code, it doesn&#39;t work for me.

I want to load `myfile.html` which i put in assets folder, and using:

    private WebView myWebView;
    
    myWebView.loadUrl(&quot;file:///android_assets/myfile.html&quot;);

On emulator shows error 

&gt; The web page at `file:///android_assets/myfile.html` could not be
&gt; loaded as: The requested file was not found.
&gt; `/android_assets/myfile.html`

When i put that file to `res/raw/` folder and using:

    myWebView.loadUrl(&quot;file:///android_res/raw/myfile.html&quot;);

then only emulator android 2.2 API level 8 can load the file probably, other older versions show the same error. Am i missing something?

Is there any way of loading an existing .html file in the application package which works on all API versions ?


Loading existing .html file with android WebView

So right now in my app the URL I&#39;m accessing has a redirect, and when this happens the WebView will open a new browser, instead of staying in my app. Is there a way I can change the settings so the View will redirect to the URL like normal, but stay in my app instead of opening a new browser?

Edit:

I want the redirecting URL, I just don&#39;t know how to create it, so the only way to get to that URL is through one that will cause a redirect to the one I want. 

For example: When you go here: http://www.amazon.com/gp/aw/s/ref=is_box_/k=9780735622777 notice how it will redirect the URL to the actual product. In my app, if I open it in a new browser, it will do that just fine, however if I keep it in my app with a WebView, it will show up as though it&#39;s doing a search for k=9780735622777, like this: http://www.amazon.com/gp/aw/s/ref=is_s_?k=k%3D9780735622777&amp;x=0&amp;y=0 . OR, it will open the view in the browser and show what is appropriate. However, I want to keep everything in my app.

Android WebView, how to handle redirects in app instead of opening a browser

Right now I have an app that loads a webview and all the clicks are kept within the app. What I would like to do is when a certain link, for example, http://www.google.com is clicked within the app it opens the default browser. If anyone has some ideas please let me know!

WebView link click open default browser

I am trying to call some javascript functions sitting in an html page running inside an android webview.  Pretty simple what the code tries to do below - from the android app, call a javascript function with a test message, which inturn calls a java function back in the android app that displays test message via toast.

The javascript function looks like:

    function testEcho(message){
         window.JSInterface.doEchoTest(message);
    }

From the WebView, I have tried calling the javascript the following ways with no luck:

    myWebView.loadUrl(&quot;javascript:testEcho(Hello World!)&quot;);
    mWebView.loadUrl(&quot;javascript:(function () { &quot; + &quot;testEcho(Hello World!);&quot; + &quot;})()&quot;);

I did enable javascript on the WebView

    myWebView.getSettings().setJavaScriptEnabled(true);
    // register class containing methods to be exposed to JavaScript
    myWebView.addJavascriptInterface(myJSInterface, &quot;JSInterface&quot;); 

And heres the Java Class

    public class JSInterface{
    
    private WebView mAppView;
    public JSInterface  (WebView appView) {
    		this.mAppView = appView;
    	}
    
    	public void doEchoTest(String echo){
    		Toast toast = Toast.makeText(mAppView.getContext(), echo, Toast.LENGTH_SHORT);
    		toast.show();
    	}
    }


I&#39;ve spent a lot of time googling around to see what I may be doing wrong.  All examples I have found use this approach.  Does anyone see something wrong here?

**Edit:**  There are several other external javascript files being referenced &amp; used in the html, could they be the issue?


Android Calling JavaScript functions in WebView

I am trying to add a progress/loading bar to my application that uses `WebView`. I am confused on how to implement a progress bar that appears every time a link is clicked.

Current code:

    public class CULearnBrowser extends Activity {
	
	    WebView webview;

    	@Override
	    public void onCreate(Bundle savedInstanceState) {
        	super.onCreate(savedInstanceState);
        	setContentView(R.layout.main);
        	webview = (WebView) findViewById(R.id.webview);
        	webview.setWebViewClient(new HelloWebViewClient());
        	webview.getSettings().setJavaScriptEnabled(true);
            webview.loadUrl(&quot;https://culearn.colorado.edu/webct/entryPageIns.dowebct&quot;);
    	}

    	private class HelloWebViewClient extends WebViewClient {
	        @Override
        	public boolean shouldOverrideUrlLoading(WebView view, String url) {
	            view.loadUrl(url);
            	return true;
	        }
    	}

    	public boolean onKeyDown(int keyCode, KeyEvent event) {
	        if ((keyCode == KeyEvent.KEYCODE_BACK) &amp;&amp; webview.canGoBack()) {
            	webview.goBack();
            	return true;
        	}
	        return super.onKeyDown(keyCode, event);
    	}
	}

Activity layout:

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;

    &lt;LinearLayout xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        android:orientation=&quot;vertical&quot;
        android:layout_width=&quot;fill_parent&quot;
        android:layout_height=&quot;fill_parent&quot;&gt;
    
        &lt;WebView  xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
            android:id=&quot;@+id/webview&quot;
            android:layout_width=&quot;fill_parent&quot;
            android:layout_height=&quot;fill_parent&quot; /&gt;

        &lt;TextView  
            android:layout_width=&quot;fill_parent&quot; 
            android:layout_height=&quot;wrap_content&quot; 
            android:text=&quot;@string/hello&quot; /&gt;
    &lt;/LinearLayout&gt;
