    <p>I don't think this is the best solution to get the javascript to execute java code. See here:</p> <p>If you want to expose native code to the HTML to be callable via javascript, do the following around your web view declaration:</p> <pre><code>JavaScriptInterface jsInterface = new JavaScriptInterface(this); webView.getSettings().setJavaScriptEnabled(true); webView.addJavascriptInterface(jsInterface, "JSInterface"); </code></pre> <p>Declare the class <code>JavaScriptInterface</code>:</p> <pre><code>public class JavaScriptInterface { private Activity activity; public JavaScriptInterface(Activity activity) { this.activity = activity; } public void startVideo(String videoAddress){ Intent intent = new Intent(Intent.ACTION_VIEW); intent.setDataAndType(Uri.parse(videoAddress), "video/3gpp"); activity.startActivity(intent); } } </code></pre> <p>I am declaring a single function for playing a video, but you can do whatever you want.</p> <p>Finally you call this in the <code>WebView</code> contents via simple javascript call:</p> <pre><code>&lt;video width="320" height="240" controls="controls" poster='poster.gif' onclick="window.JSInterface.startVideo('file:///sdcard/test.3gp');" &gt; Your browser does not support the video tag. &lt;/video&gt; </code></pre> <p>The example is taken from another answer of mine, about playing videos, but should be explaining enough.</p> <p><strong>EDIT</strong> As per @CedricSoubrie's comment: if the target version of the application is set to 17 or higher you need to add annotation <code>@JavascriptInterface</code> above each method you want to export to the web view.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
