Answer 1

If your activity outside main package then declare like this :

Instead of

Intent intent = new Intent();

intent.setClassName("com.nous.demoexample", "com.nous.demoexample.Dateactvity");

Write like this :

Intent oIntent = new Intent(getApplicationContext(), com.nous.demoexample.Dateactvity.class);
