just do the folllowing this will start activity in portrait mode.

In the manifest, set this for all your activities:

    android:screenOrientation="portrait"/>

Answer 3

You might create two acitivties which is either started in landscape or portrait mode. To disable the opposite, do as already said.

android:screenOrientation="portrait"

Answer 4

Simple Once your app is started get the orientation of the device.Then set that orientation to all your activities.

In your first activity's onCreate method get the current orientation of the device like this

 int orientation = getResources().getConfiguration().orientation;
 setRequestedOrientation(orientation);

This will set the orientation for the current activity only.But if you want to set the whole app to this mode then try this Create a helper class like this

 Class ActivityHelper{

      public static void setOrientation(Activity activity,int orientation){
          activity.setRequestedOrientation(orientation);
      }
 }

in your Everyactivity after setContentView call

ActivityHelper.setOrientation(this,orientation);//Keep orientation as a static variable
