When starting a new activity you can send data through intent. 

Intent intent = new Intent( this, Activity2.class );
intent.putExtra( "key", "value" );
startActivity(intent)

And in second activity do like this:

getIntent().getStringExtra( "key" );

or if you are sending int for example 

getIntent().getIntExtra( "key", 0 );
