    <p>I've encountered a problem with Google-Charts in the WebView on Android 4.0.4</p> <p>I've got a little page with a Google-Chart on it, so if I display this html-page in the browser the chart shows up just fine. If I start my App on the Samsung Galaxy 7 (Android 2.2) the Google-Chart shows up just fine in the WebView too. But if I start the same App on the Samsung Galaxy 10.1 (Android 4.0.4) the WebView with the Google-Chart is just empty, no error-message or something else, that might be usefull for debugging.</p> <p>Essentially I just try to load the Google-Chart URL into the WebView:</p> <pre class="lang-java prettyprint-override"><code>String url = &lt;google-chart-url&gt;; // is there something strange with the content? showContent(url); WebView webview = ((WebView) findViewById(R.id.webview)); webview.loadUrl(url); </code></pre> <p>Little HTTP-Request to verify that the data from the server is okay:</p> <pre class="lang-java prettyprint-override"><code>private void showContent(String url) { int TIMEOUT_CONNECTION = 60000; int TIMEOUT_SOCKET = 60000; // Parameter setzen HttpParams httpParams = new BasicHttpParams(); HttpConnectionParams.setConnectionTimeout(httpParams, TIMEOUT_CONNECTION); HttpConnectionParams.setSoTimeout(httpParams, TIMEOUT_SOCKET); HttpClient httpClient = new DefaultHttpClient(httpParams); // Daten holen HttpGet getMethod = new HttpGet(url); HttpResponse response; String raw = new String(); try { response = httpClient.execute(getMethod); HttpEntity responseEntity = response.getEntity(); if(responseEntity != null) { raw = EntityUtils.toString(responseEntity); } Log.d(LOG_TAG, "showContent: " + raw); } catch (IOException e) { Log.e(LOG_TAG, e.getMessage(), e); } } </code></pre> <p>I also tried different WebView settings:</p> <pre class="lang-java prettyprint-override"><code>WebView webview = (WebView) findViewById(R.id.webview); // JavaScriptInterface to handle clicks in the WebView webview.addJavascriptInterface(new HtmlClick(), "clicks"); webview.getSettings().setJavaScriptEnabled(true); webview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true); </code></pre> <p>Is there anyone who encountered a similiar problem or does someone have suggestions what is actually bugged?</p> <p>Thanks in advance ;)</p> <h3>Update:</h3> <p>The Browser on the Samsung Galaxy 10.1 also dosen't display the chart; tested with:</p> <ul> <li>Internet</li> <li>Chrome</li> <li>Firefox</li> <li>Opera</li> </ul>

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.

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