how to make OnNewIntent work inside tabs

Question

I am working on a project where I have 3 tabs. The first tab is used to write information to NFC tag where the other 2 tabs are used to read the information from the NFC tag. However, I am facing a problem with OnNewIntent() method. As I understood correctly from reading online is that this method is used only in activities and not in fragments. I have looked at similar questions and answers but I don't fully understand what needs to be done to avoid this issue in my situation.

Here is my code for the first tab where I write some data to NFC tag:

public class Home extends Fragment {

NfcAdapter nfcAdapter;
Button writebtn;
Tag tag;
EditText txtName, txtCountry, txtID;

public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view,savedInstanceState);
    nfcAdapter = NfcAdapter.getDefaultAdapter(getContext());

    txtName = (EditText)view.findViewById(R.id.personName);
    txtCountry= (EditText)view.findViewById(R.id.personCountry);
    txtID= (EditText)view.findViewById(R.id.personID);
    writebtn=(Button)view.findViewById(R.id.nfcWriteBtn);

}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
    View v= inflater.inflate(R.layout.home, container,false);
    return v;
}

@Override
public void onResume() {
    super.onResume();
    if(nfcAdapter !=null){
        enableForegroundDispatchSystem();
    }
}

@Override
public void onPause() {
    super.onPause();
    disableForegroundDispatchSystem();
}

protected void onNewIntent(final Intent intent) {
    // super.onNewIntent(intent);
    getActivity().getIntent();

    if (intent.hasExtra(NfcAdapter.EXTRA_TAG)) {
        Toast.makeText(getContext(), "NFC tag discovered!", Toast.LENGTH_SHORT).show();

        tag = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);
        writebtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                NdefMessage ndefMessage = createNdefMessage(txtName.getText().toString(), txtCountry.getText().toString(),txtID.getText().toString());

                writeNdefMessage(tag, ndefMessage);
            }
        });
    }

}

Answer 1

onNewIntent(Intent intent) belongs to Activity you cannot have it in fragment. What you can do is pass the data to your fragment whenever onNewIntent(Intent intent) get called in Activity. To achieve this You need to override onNewIntent() in Activity and notify the fragments about intent . Do not use getIntent() use the intent which is in argument.

 @Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    // Notify fragment about the new intent
}

And your Fragments method should look like .

 protected void onNewIntent( Intent intent) {
    if (intent.hasExtra(NfcAdapter.EXTRA_TAG)) {
        Toast.makeText(getContext(), "NFC tag discovered!", Toast.LENGTH_SHORT).show();
        tag = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);
        writebtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                NdefMessage ndefMessage = createNdefMessage(txtName.getText().toString(), txtCountry.getText().toString(),txtID.getText().toString());
                writeNdefMessage(tag, ndefMessage);
            }
        });
    }
