2

static final int FRAGMENT_ONE_REQUEST = 1;  // The request code
static final int FRAGMENT_TWO_REQUEST = 2;  // The request code

then use this from fragment one

 startActivityForResult(intent, FRAGMENT_ONE_REQUEST);

then use this from fragment two

startActivityForResult(intent, FRAGMENT_TWO_REQUEST);

in each fragment

@Override
  public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if(resultCode == Activity.RESULT_OK) {
       //some code
         if (requestCode == FRAGMENT_ONE_REQUEST) {
       }
    }
}

bro how can I use startActivityForResult in fragment..can you send me a full code – pruthvi raj May 11 '16 at 06:21
Why did you check requestCode in the first condition ? You either check if this is OK then manage the request code OR you manage the request code and the resultCode for each but here, if you came from FRAGMENT_TWO, this won't work. – AxelH May 11 '16 at 07:00
that was my bad. simple copy paste error. corrected! thanx! @AxelH – Nilesh Deokar May 11 '16 at 07:08
You are welcome, add the condition for Frag_two just to be complete and you have my vote. – AxelH May 11 '16 at 07:17
see my full codebutton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { IntentIntegrator integrator = new IntentIntegrator(getActivity()); integrator.initiateScan(); this i added in fragment and onactivity result method i added in activity – pruthvi raj May 11 '16 at 07:42
