Prevent Activity to recreated Most common solution to dealing with orientation changes by setting the android configChanges flag on your Activity in AndroidManifest xml  Using this attribute your Activities won   t be recreated and all your views and data will still be there after orientation change   lt activity     android name  quot com example test activity MainActivity quot      android configChanges  quot orientation screenSize keyboardHidden quot   gt   this is work for me

It s my experience that it s actually better to just deal with the orientation changes properly instead of trying to shoehorn a non-default behavior    You should save the image that s currently being displayed in onSaveInstanceState   and restore it properly when your application runs through onCreate   again

Add this code after the onCreate  method in your activity containing the WebView   Override protected void onSaveInstanceState Bundle outState        super onSaveInstanceState outState           Override protected void onRestoreInstanceState Bundle state        super onRestoreInstanceState state

Xion s answer was close  but  3  android configChanes  orientation   won t work unless the application has an API level of 12 or lower   In API level 13 or above  the screen size changes when the orientation changes  so this still causes the activity to be destroyed and started when orientation changes   Simply add the  screenSize  attribute like I did below    lt activity     android name   YourActivityName      android configChanges  orientation screenSize  gt   lt  activity gt    Now  when you change orientation  and screen size changes   the activity keeps its state and onConfigurationChanged   is called  This will keep whatever is on the screen  ie  webpage in a Webview  when the orientation changes   Learned this from this site  http   developer android com guide topics manifest activity-element html  Also  this is apparently a bad practice so read the link below about Handling Runtime Changes   http   developer android com guide topics resources runtime-changes html

This solution is by far the best working one  In your manifest file add   lt activity     android configChanges  keyboardHidden orientation screenSize      android name  your activity name      android label   string app name       android screenOrientation  landscape  gt     lt  activity   And in your activity class add the following code   Override public void onConfigurationChanged Configuration newConfig         super onConfigurationChanged newConfig       if  newConfig orientation    Configuration ORIENTATION PORTRAIT              your code       else if  newConfig orientation    Configuration ORIENTATION LANDSCAPE        your code

There are generally three ways to do this    As some of the answers suggested  you could distinguish the cases of your activity being created for the first time and being restored from savedInstanceState  This is done by overriding onSaveInstanceState and checking the parameter of onCreate  You could lock the activity in one orientation by adding android screenOrientation  portrait   or  landscape   to  lt activity gt  in your manifest   You could tell the system that you meant to handle screen changes for yourself by specifying android configChanges  orientation screenSize  in the  lt activity gt  tag  This way the activity will not be recreated  but will receive a callback instead  which you can ignore as it s not useful for you     Personally I d go with  3   Of course if locking the app to one of the orientations is fine with you  you can also go with  2

I dont know if the a best solution  but i describe it here   First of all  you need certificate with you class Application of your app is in your manifest of this    lt application     android name   App            Second  in my class App i did like this   public class App extends Application       public static boolean isOrientationChanged   false        Override     public void onCreate             super onCreate                Override     public void onConfigurationChanged  NotNull Configuration newConfig            super onConfigurationChanged newConfig           if  newConfig orientation    Configuration ORIENTATION LANDSCAPE                    newConfig orientation    Configuration ORIENTATION PORTRAIT                isOrientationChanged   true                       Third  you need to set a flag to Orientation Change  in my case  I always set it when the previous activity within the app navigation is called  so only calling once when the later activity is created   isOrientationChanged   false    So every time I change the orientation of my screen in that context  I set it every time it changes this setting  it checks if there is a change in orientation  if so  it validates it based on the value of that flag   Basically  I had to use it whenever I made an asynchronous retrofit request  which he called every moment that changed orientation  constantly crashing the application   if   isOrientationChanged        presenter retrieveAddress this  idClient  TYPE ADDRESS       I don t know if it s the most elegant and beautiful solution  but at least here it s functional

You just have to go to the AndroidManifest xml and inside or in your activities labels  you have to type this line of code as someone up there said   android configChanges  orientation screenSize    So  you ll have something like this    lt activity android name  ActivityMenu  android configChanges  orientation screenSize  gt   lt  activity gt    Hope it works

Just add this to your AndroidManifest xml   lt activity android screenOrientation  landscape  gt    I mean  there is an activity tag  add this as another parameter  In case if you need portrait orientation  change landscape to portrait  Hope this helps
