Answer 1

In the parent Activity I would create an Intent to the Child activity. Then use putExtra to send data. Then use getExtra or any variation on that to get the String. I have used getStringExtra in this example.

Intent childActivity = new Intent(this, Child.class);
childActivity.putExtra("parent_parameter", "This String is for child");
startActivity(childActivity); 

In the Child.java Activity.

Intent childIntent = getIntent();
String fromParent = childIntent.data.getStringExtra("parent_parameter");
