The easiest way is to put this in the onCreate()
method of all your Activities (better yet, put it in a BaseActivity class and extend all your Activities from it)
@Override
protected void onCreate(Bundle bundle) {
super.onCreate(bundle);
if (isLargeDevice(getBaseContext())) {
this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);
} else {
this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}
}
You can use this method to detect if the device is a phone or tablet:
private boolean isLargeDevice(Context context) {
int screenLayout = context.getResources().getConfiguration().screenLayout;
screenLayout &= Configuration.SCREENLAYOUT_SIZE_MASK;
switch (screenLayout) {
case Configuration.SCREENLAYOUT_SIZE_SMALL:
case Configuration.SCREENLAYOUT_SIZE_NORMAL:
return false;
case Configuration.SCREENLAYOUT_SIZE_LARGE:
case Configuration.SCREENLAYOUT_SIZE_XLARGE:
return true;
default:
return false;
}
}
