Lock screen orientation Android

Question

I m writing an android application that uses tabs with different contents  activities   In one of these activities  I would like to lock the screen orientation to  Landscape -mode  but in the other activities  I want the normal orientation  according to sensor    What I m doing now is that I m calling   setRequestedOrientation ActivityInfo SCREEN ORIENTATION LANDSCAPE     when I switch to the landscape mode activity  and   setRequestedOrientation ActivityInfo SCREEN ORIENTATION SENSOR     when I switch back to the other activities  However  this doesn t seem to work  the whole application locks up  What is the normal approach to this problem

I had a similar problem     When I entered    lt activity android name  MyActivity  android screenOrientation  landscape  gt  lt  activity gt    In the manifest file this caused that activity to display in landscape   However when I returned to previous activities they displayed in lanscape even though they were set to portrait   However by adding    setRequestedOrientation ActivityInfo SCREEN ORIENTATION PORTRAIT     immediately after the OnCreate section of the target activity resolved the problem   So I now use both methods

In the Manifest  you can set the screenOrientation to landscape  It would look something like this in the XML    lt activity android name  MyActivity  android screenOrientation  landscape  android configChanges  keyboardHidden orientation screenSize  gt       lt  activity gt    Where MyActivity is the one you want to stay in landscape   The android configChanges     line prevents onResume    onPause   from being called when the screen is rotated  Without this line  the rotation will stay as you requested but the calls will still be made   Note  keyboardHidden and orientation are required for  lt  Android 3 2  API level 13   and all three options are required 3 2 or above  not just orientation

inside the Android manifest file of your project  find the activity declaration of whose you want to fix the orientation and add the following piece of code     android screenOrientation  landscape    for landscape orientation and for portrait add the following code   android screenOrientation  portrait
