How to start an activity after a preset time in Android?

I have been trying with starting an activity after a pre determined time set by the user. I have two activities, one is sending some strings to another activity by means of:

Intent go = new Intent(MainActivity.this, CallComeActivity.class);

            go.putExtra("sub", name);
            go.putExtra("photo_path", fname);
            go.putExtra("text", number);

            startActivity(go);

I am receiving these strings using:

    String sub = intent.getStringExtra("sub");
    String photo_path=intent.getStringExtra("photo_path");
    String text = intent.getStringExtra("text");

Now I need to start this second activity after some time. I have tried with BroadCast Receiver but I am not able to send these strings to the second class using Broadcast Receiver. I am only able to trigger the second class without passing these strings. Please Help.
