Ignore this answer. Not that it doesn't work. But there are better methods available. Moreover, Android emphatically discourage direct communication between fragments. See official doc. Thanks user @Wahib Ul Haq for the tip.

Original Answer

Well, you can create a private variable and setter in Fragment B, and set the value from Fragment A itself,

FragmentB.java

private String inputString;
....
....

public void setInputString(String string){
   inputString = string;
}

FragmentA.java

//go to fragment B

FragmentB frag  = new FragmentB();
frag.setInputString(YOUR_STRING);
//create your fragment transaction object, set animation etc
fragTrans.replace(ITS_ARGUMENTS)

Or you can use Activity as you suggested in question..
