Prevent screen rotation on Android

Question

I have one of my activities which I would like to prevent from rotating because I m starting an AsyncTask  and screen rotation makes it restart   Is there a way to tell this activity  DO NOT ROTATE the screen even if the user is shaking his phone like mad

You can follow the logic below to prevent auto rotate screen while your AsyncTask is running:

Store your current screen orientation inside your activity using getRequestedOrientation().
Disable auto screen orientation using setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR).
Run/execute your AsyncTask.
At the end of your AsyncTask restore your previous orientation status using setRequestedOrientation(oldOrientation).

Please note that there are several ways to access Activity (which runs on UI thread) properties inside an AsyncTask. You can implement your AsyncTask as an inner class or you can use message Handler that poke your Activiy class.

If you are using Android Developer Tools  ADT  and Eclipse you can go to your AndroidManifest xml --  Application tab --  go down and select your activity  Finally  select your preferred orientation  You can select one of the many options

Add the following to your AndroidManifest xml     app   src   main   AndroidManifest xml     lt activity android name   MainActivity            android configChanges  orientation            android screenOrientation  portrait   gt    Example    lt  xml version  1 0  encoding  utf-8   gt   lt manifest xmlns android  http   schemas android com apk res android  package  xxx zzzzzz yyyyy  gt       lt uses-permission android name  A-PERMISSION    gt       lt application gt         lt activity android name   MainActivity                  android screenOrientation  portrait                  android configChanges  orientation  gt         lt  activity gt      lt  application gt    lt  manifest gt

The following attribute on the ACTIVITY in AndroidManifest xml is all you need   android configChanges  orientation    So  the full activity node would be    lt activity android name  Activity1            android icon   drawable icon            android label  App Name            android excludeFromRecents  true            android configChanges  orientation  gt       lt intent-filter gt           lt action android name  android intent action MAIN   gt           lt category android name  android intent category LAUNCHER   gt       lt  intent-filter gt   lt  activity gt

Rather than going into the AndroidManifest  you could just do this   screenOrientation   getResources   getConfiguration   orientation  getActivity   setRequestedOrientation ActivityInfo SCREEN ORIENTATION LOCKED       AsyncTask  screenOrientation   getResources   getConfiguration   orientation     Override protected void onPostExecute String things        context setRequestedOrientation PlayListFragment screenOrientation       or      context setRequestedOrientation ActivityInfo SCREEN ORIENTATION FULL SENSOR       The only drawback here is that it requires API level 18 or higher  So basically this is the tip of the spear

User · Answer

Add   android screenOrientation  portrait     or   android screenOrientation  landscape     to the  lt activity gt  element s in the manifest and you re done

Use AsyncTaskLoader to keep your data safe even if the activity changes  instead of using AsyncTask that is a better way to build apps than preventing screen rotation

User · Answer

The easiest way I found to do this was to put   this setRequestedOrientation ActivityInfo SCREEN ORIENTATION PORTRAIT     within onCreate  just after  setContentView R layout activity main     so      Override protected void onCreate Bundle savedInstanceState      super onCreate savedInstanceState     setContentView R layout activity main     this setRequestedOrientation ActivityInfo SCREEN ORIENTATION PORTRAIT

Prevent Screen Rotation just add this following line in your Manifests    lt activity         android name   YourActivity          android screenOrientation  portrait    gt    This works for me

User · Answer

User  portrait  in your AndroidManifest xml file might seem like a good solution  But it forces certain devices  that work best in landscape  to go into portrait  not getting the proper orientation  On the latest Android version  you will get wearing an error  So my suggestion it s better to use  nosensor     lt activity                                 android screenOrientation  nosensor  gt

In your Manifest file  for each Activity that you want to lock the screen rotation add  if you want to lock it in horizontal mode    lt activity                                 android screenOrientation  landscape  gt    or if you want to lock it in vertical mode    lt activity                                             android screenOrientation  portrait  gt
