goffioul opened a new issue #722: Keyboard focus not restored to last element on app resume
URL: https://github.com/apache/cordova-android/issues/722
 
 
   # Bug Report
   
   ## Problem
   When resuming a cordova app, the keyboard focus is moved instead of being restored to the last focused element.
   ### What is expected to happen?
   When the cordova app is paused and there was a focused element in the webview content, one expect the focus to be restored to that element when the app is resumed.
   
   
   ### What does actually happen?
   The focus is moved to the first element in the page that has a non-negative tabIndex, otherwise to the document body (ignoring the elements with negative tabIndex).
   
   
   ## Information
   This behavior has been introduced with this commit: https://github.com/apache/cordova-android/commit/c2cafb4b45fcbb307a113828dfc9f723f8a6433b
   
   
   
   ### Command or Code
   - Create a new cordova app and add android platform.
   - Add the following to `div.class` element in www/index.html:
   ```
   <div id="focusable1" tabIndex="0">I am focusable</div>
   <div id="focusable2" tabIndex="0">I am also focusable</div>
   <input type="text">
   ```
   - Add the following to www/css/index.css:
   ```
   #focusable1:focus { background: yellow; }
   #focusable2:focus { background: red; }
   ```
   - Add the following to `app.receivedEvents` method in www/js/index.js:
   ```
   document.getElementById('focusable1').focus();
   ```
   - Compile and install the app
   - On app launch, the first focusable element should have the focus, with yellow background
   - Using mouse or keyboard, focus the second element, with red background
   - Using adb, launch another app, e.g. `adb shell am start com.android.settings/.Settings`
   - Resume cordova app, e.g. quit settings using the BACK button
   
   Focus will be restored to the first element, with yellow background. If using `tabIndex="-1"` instead for the focusable elements, focus will be moved to the input element.
