My Webview Reloads When I Change From Portrait To Landscape

Question

I have a simple WebView that runs a web application on an Android. The problem is when I rotate the phone to change it to landscape the webview reloads and goes back to the beginning.

How can I prevent this action?

Answer 1

This can be resolved by overriding onSaveInstanceState(Bundle outState) in your activity and calling saveState from the Webview:

Answer 2

Beginning with Android 3.2 (API level 13), the "screen size" also changes when the device switches between portrait and landscape orientation. Thus, if you want to prevent runtime restarts due to orientation change when developing for API level 13 or higher (as declared by the minSdkVersion and targetSdkVersion attributes), you must include the "screenSize" value in addition to the "orientation" value. That is, you must decalare

<activity android:configChanges="orientation|screenSize">

Here's the docs: http://developer.android.com/guide/topics/resources/runtime-changes.html

Answer 3

Add the following to your AndroidManifest:

android:configChanges="orientation|keyboard|keyboardHidden"

So it should look something like this:

<activity android:name=".MyActivity" 
          android:label="@string/app_name" 
          android:configChanges="orientation|keyboard|keyboardHidden">

Obviously, if your WebView needs keyboard support then don't include the keyboard options.

Answer 4

Add this before the oncreate

@Override
protected void onSaveInstanceState(Bundle outState) {
webview.saveState(outState);
}

Write the oncreate this way. put final

public void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layoutname);
if (savedInstanceState != null)
{
((WebView)findViewById(R.id.webview)).restoreState(savedInstanceState);
}
else
{
webview.loadUrl("http://www.playbuzz.org/");
}

}

In Androidmanifest insert under the activity

android:configChanges="keyboardHidden|orientation"
