    <p>This is my first app, it is a web app, it simply loads a webView to a url where stuff happens.</p> <p>It works fine in android browser(gingerbread), but in Chrome(ICS, JB) it was going back to the initial webView url when the device is rotated. In gingerbread you account for this by setting android:configChanges="keyboard|keyboardHidden|orientation" and overriding onConfigurationChanged.</p> <p>After searching the web, I re-wrote my original activity as per the example here: <a href="http://www.devahead.com/blog/2012/01/preserving-the-state-of-an-android-webview-on-screen-orientation-change/" rel="nofollow">http://www.devahead.com/blog/2012/01/preserving-the-state-of-an-android-webview-on-screen-orientation-change/</a> , in which you essentially handle the re-orientation yourself.</p> <p><b>However now my app is crashing when I rotate the device.</b></p> <p>Testing with Android 4.1.2.</p> <p>Anyone see anything off with my code? Sorry if the answer is obvious, but I've been stuck on this bug for a couple of days now. Maybe I just need another set of eyes on it. Thanks in advance!</p> <p><i>Note: the line @SuppressWarnings("deprecation") is not in the example, it was suggested by the editor in order to compile.</i></p> <p>The Main Activity:</p> <pre><code>package com.example.xxx.xxx; import android.os.Bundle; import android.annotation.SuppressLint; import android.app.ActionBar.LayoutParams; import android.app.Activity; import android.content.res.Configuration; import android.view.Menu; import android.view.ViewGroup; import android.webkit.WebChromeClient; import android.webkit.WebSettings; import android.webkit.WebView; import android.webkit.WebViewClient; import android.widget.FrameLayout; @SuppressLint("SetJavaScriptEnabled") public class MainActivity extends Activity { protected FrameLayout webViewPlaceholder; protected WebView myWebView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); initUI(); } @SuppressWarnings("deprecation") protected void initUI() { webViewPlaceholder = ((FrameLayout)findViewById(R.id.webViewPlaceholder)); if (myWebView == null){ //Create It myWebView = new WebView(this); myWebView.setLayoutParams(new ViewGroup.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); WebSettings webSettings = myWebView.getSettings(); webSettings.setJavaScriptEnabled(true); webSettings.setSupportZoom(true); webSettings.setBuiltInZoomControls(true); webSettings.setLoadsImagesAutomatically(true); myWebView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY); myWebView.setScrollbarFadingEnabled(true); myWebView.setWebViewClient(new WebViewClient()); myWebView.setWebChromeClient(new WebChromeClient()); myWebView.setInitialScale(1); myWebView.loadUrl("http://www.theurl.com"); } webViewPlaceholder.addView(myWebView); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu); return true; } @Override public void onConfigurationChanged(Configuration newConfig){ if (myWebView != null) { webViewPlaceholder.removeView(myWebView); } super.onConfigurationChanged(newConfig); setContentView(R.layout.activity_main); initUI(); } @Override protected void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); // Save the state of the WebView myWebView.saveState(outState); } @Override protected void onRestoreInstanceState(Bundle savedInstanceState) { super.onRestoreInstanceState(savedInstanceState); // Restore the state of the WebView myWebView.restoreState(savedInstanceState); } } </code></pre> <p>Main Activity XML:</p> <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" &gt; &lt;FrameLayout android:id="@+id/webViewPlaceholder" android:layout_width="fill_parent" android:layout_height="fill_parent"/&gt; &lt;/LinearLayout&gt; </code></pre>

    1. COI just updated to Android 4.2 minutes after this post, and the saving/loading of states is now working. Now I need to figure out how to keep my form data intact. Any ideas?

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).
