Change screen orientation in Android without reloading the activity

Question

I want to change the orientation programmatically while running my Android App, with these lines of code:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);  
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);

They work so far, but the main problem is that the whole activity is reloaded when the screen orientation changes, and I don't want that. Is it possible? Thanks.

EDIT: OK, after I while I found out what I was missing. I had to include also "screenSize" in the configChanges property, so having

android:configChanges="orientation|screenSize"

solved the whole thing.

I think you should check out the third choice in this answer. I believe that is how PhoneGap handles orientation changes http://stackoverflow.com/questions/5913130/dont-reload-application-when-orientation-changes — MikeIsrael, Feb 14 '13 at 11:31

See the edit by @luisfer. For targeting Android 3.2 and above, you need BOTH

android:configChanges="orientation|screenSize"

You need to override onSaveInstanceState(Bundle savedInstanceState) and write the application state values you want to change to the Bundle parameter

In AndroidManifest file add android:configChanges="orientation" for the activity you want to handle this orientation

In activity use onConfigurationChange overrided method. Do task you want to handle in orientation change.

Thank you, but it still doesn't work. Could it be maybe because I'm using Phonegap/HTML5 in the activity? Thank you. – luisfer Feb 14 '13 at 11:45

Call this method And Set manifest file

android:configChanges="orientation|screenSize|keyboardHidden"

public void onConfigurationChanged(Configuration newConfig) {
     super.onConfigurationChanged(newConfig);

        // Checks the orientation of the screen
        if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
            Toast.makeText(this, "landscape", Toast.LENGTH_SHORT).show();
        } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
            Toast.makeText(this, "portrait", Toast.LENGTH_SHORT).show();
        }
    }
