Doesn't work inside Fragments

The problem is not avoidable with IntentIntegrator.initiatescan(getActivity()) because it wouldn’t trigger Fragment onActivityResult.

Current workaround:

Intent i = IntentIntegrator.createScanIntent(getActivity(), null, null);
i.setAction(Intents.Scan.ACTION);
i.putExtra("RESULT_DISPLAY_DURATION_MS", 0L);
startActivityForResult(i, IntentIntegrator.REQUEST_CODE);

In this fork I added some methods so that you can do the following:

Intent intent = IntentIntegrator.createScanIntent(this);
startActivityForResult(intent, IntentIntegrator.REQUEST_CODE);

This takes care of most of the boilerplate configuration, but allows you do customize properties on the intent further as you want. It should also work better for usage from a Fragment.

For more methods, see the IntentIntegrator source.

Thanks for your suggestion. My problem is scanning QRCode from DialogFragment. So I did it like this:

IntentIntegrator.forSupportFragment(this).setPrompt(“Scan a barcode or QRCode”).initiateScan();

This is worked for me.
