Answer 1

Move start intent code in onResume :

@Override
protected void onResume() {
   super.onResume();
   Handler handler=new Handler();
   handler.postDelayed(new Runnable() {
     @Override
     public void run() {
        Intent in = new Intent(this,MainActivity.class);
        startActivity(in);
        overridePendingTransition(R.anim.trans_left_in,R.anim.trans_left_out);
     }
    }, 3000);
}

You can finish the first activity:

finish();

Then, in the second activity, you can re-start the first activity with this intent:

Intent i = new Intent(SecondActivity.this, FirstActivity.class);
startActivity(i);
finish();
