Have you tried this in your Activity?

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

//This is the default value
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);

After that you can use this to disable the auto orientation:

public static void setAutoOrientationEnabled(ContentResolver resolver, boolean enabled)
{
  Settings.System.putInt(resolver, Settings.System.ACCELEROMETER_ROTATION, enabled ? 1 : 0);
}

I don't want to change the orientation of a activity alone, but want to change the Settings. I want to enable and disable Auto rotation screen of Android settings. – Santhosh_pulliman Mar 15 '12 at 12:05
After exiting from my application, the device should not be able to auto rotate the screen. – Santhosh_pulliman Mar 15 '12 at 12:13

you can use this:

android.provider.Settings.System.putInt(getContentResolver(),
android.provider.Settings.System.USER ROTATION,user_rotation);

for rotation policy

user_rotation 0 -> ROTATION_0
user_rotation 1 -> ROTATION_90
user_rotation 2 -> ROTATION_180
user_rotation 3 -> ROTATION_270

see http://developer.android.com/reference/android/provider/Settings.System.html#USER_ROTATION for more.

Also menifiest.xml setting

<uses-permission android:name="android.permission.WRITE_SETTINGS"></uses-permission>

You set default rotation settings in your manifest file e.g:

<activity android:name=".MainTabActivity" android:screenOrientation="portrait">
</activity>

To change orientation programatically you have to call Activity.setRequestedOrientation()
