Just a sample code:

Intent intent = new Intent(FirstActivity.this, SecondActivity.class);
Bundle b = new Bundle();

b.putInt("key", 1);

intent.putExtras(b);

startActivity(intent);

finish();

After it, we can get this data in a second activity:

Bundle b = getIntent().getExtras();

int value = b.getInt("key", 0);

You can return result to 1st activity. Refer to this .

As mentioned: Consider Activity1 calling startActivityForResult. In Activity 2 call setResult and immediately call finish(). Back in Activity1 capture the return values in onActivityResult.
