When i changed screen from portrait mode to land scape mode then automatically came out from my application.(same as landscape to portrait also)can any one tell me the solution for this..

this is my code for orientation,

```
if (this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
            Toast.makeText(MyAlphabetsActivity.this, "ORIENTATION_PORTRAIT",
                    Toast.LENGTH_SHORT).show();
            setContentView(R.layout.portrait_main);
            System.out.println("int-----1--");
        } else if (this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
            setContentView(R.layout.landscape_main);
            Toast.makeText(MyAlphabetsActivity.this, "ORIENTATION_LANDSCAPE",
                    Toast.LENGTH_SHORT).show();
            System.out.println("int-----2--");
        }
