using initiateScan() in android.support.v4.app.Fragment is not invoking onActivityResult()

I tried the following inside the android.support.v4.app.Fragment:

 IntentIntegrator integrator = new IntentIntegrator(getActivity());

The constructor for the Fragment is only available for the native Fragment provided by the SDK in the device not the support-v4 or package. After deeper investigation i find out that the REQUEST_CODE: https://github.com/zxing/zxing/blob/6c522f127a0ac40b2e14518528c9547018e044b2/android-integration/src/main/java/com/google/zxing/integration/android/IntentIntegrator.java#L112

value seems the issue. It prevents later in the FragmentActivity here: http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/5.0.0_r1/android/support/v4/app/FragmentActivity.java/#150 that the index is not 0. Then it traverses through all fragments and invokes onActivityResult() properly. I set a breakpoint with the debugger and modified the REQUEST_CODE and it works. I haven’t tested it if this implies other problems.

Would be nice to have your feedback. Thank you very much for reading.

The problem is that there is no constructor for IntentIntegrator that takes android.support.v4.preference.PreferenceFragment. Could you implement such a constructor?

The code in the second comment should work, but I’d rather not use that ugly hack.

I suppose I’m asking whether the “312” is the necessary change, or calling startActivity on the Fragment? I would not expect that the value matters as long as its top 16 bits are 0 (these are reserved from Android 3.x onward IIRC). I also expect that you can use the constructor for Fragment if you need its method invoked. Do we need a different, other constructor?
