onNewIntent never being called in Activity

I have asked multiple questions on SO regarding different problems I am having with onNewIntent method in both fragments and activities. My problem now is that onNewIntent in Activity is never being called no matter what I do. The Activity that has the onNewIntent contains multiple tabs. My tabs (Fragments) contain codes for writing and reading NFC tag.
This is the code for the Activity:
public class MyAppHome extends AppCompatActivity {
protected DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mtoggle;
NfcAdapter nfcAdapter;
private Toolbar mtoolbar;
private TextView mName;
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
private NavigationView mNavigationView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.drawer_layout);
mtoolbar = (Toolbar) findViewById(R.id.nav_action);
setSupportActionBar(mtoolbar);
nfcAdapter = NfcAdapter.getDefaultAdapter(this);
mNavigationView= (NavigationView)findViewById(R.id.nav_view);
mDrawerLayout = findViewById(R.id.drawer_layout);
mtoggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.open, R.string.close);
mDrawerLayout.addDrawerListener(mtoggle);
mtoggle.syncState();
// Create the adapter that will return a fragment for each of the three
// primary sections of the activity.
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.addOnTabSelectedListener(new TabLayout.ViewPagerOnTabSelectedListener(mViewPager));
tabLayout.setupWithViewPager(mViewPager);
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override

Home Fragment (tab) is used to write information 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);
}
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, Bundle savedInstanceState) {
View v= inflater.inflate(R.layout.home, container,false);
txtName = (EditText)view.findViewById(R.id.pName);
txtCountry= (EditText)view.findViewById(R.id.pCountry);
txtID= (EditText)view.findViewById(R.id.pID);
writebtn=(Button)view.findViewById(R.id.nfcWriteBtn);
writebtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
MyAppHome homeActivity = (MyAppHome)getActivity();
MyNfcMessage message = new MyNfcMessage(txtName.getText().toString(), txtCountry.getText().toString(), txtID.getText().toString());
homeActivity.write2NFC(message);
}
});
return v;
}
I don't Understand Why onNewIntent in the Activity is never being called (No Toasts are being displayed on screen). Does it have something to do with my layout?
Update: The problem was solved by creating a new project and copying all the code from the old project to the new one.

In manifest.xml, in an activity tag set launchmode="singleTask"

Navigation drawer is not updating selected state onBackPressed

I am A Beginner in android development, actually I have a Navigation drawer with Fragments my issue is when i go to fragment b from a the state in navigation drawer is updating to fragment b successfully but when go to fragment B From Fragment A by on 'backpressed' method the drawer item state is not updating / changing to fragment A . please help me in fixing this.

When you popBackStack() the fragment from back stack will appear on screen so you need to listen for Back stack changes.
getSupportFragmentManager().addOnBackStackChangedListener(new FragmentManager.OnBackStackChangedListener() {
#Override
public void onBackStackChanged() {
Fragment fragment = getSupportFragmentManager().findFragmentById(R.id.containerFrame);
if (fragment != null) {
// check for fragment and set the drawer state
if(fragment instanceof Frag1){
// set drawer state for 1
}else if(fragment instanceof Frag2){
// set drawer state for 2
}
}
}

Any ideas about the cause of this issue?

Try this first setContentView(R.layout.activity_main); than perform your action
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.myAppDatabaseHandler= MyAppDatabaseHandler.getInstance(this);
defaultPrefs = PreferenceManager.getDefaultSharedPreferences(this);

How to handle camera while switching between fragments?

I am switching between 2 different fragments using 2 buttons. One fragment has a camera view and opens pretty well for the first time, but when returning to the same fragment again from second fragment gives a blank screen. camera preview cannot be seen although camera hardware is free.I am NOT using camera2 api but needs a solution to this bug. i have added my complete code and images for assistance.

Can you try this, remove onAttach and onDetach. Also replace this code in onCreate
if (checkCameraHardware(getActivity().getApplicationContext())) {
Toast.makeText(this.getActivity(), "camera hardware is free", Toast.LENGTH_SHORT).show();
zXingScannerView = new ZXingScannerView(this.getActivity().getApplicationContext());
zXingScannerView.setResultHandler(this);
zXingScannerView.startCamera(0);
} else {
Toast.makeText(this.getActivity(), "camera hardware is NOT free", Toast.LENGTH_SHORT).show();
}
with this.
zXingScannerView = new ZXingScannerView(this.getActivity().getApplicationContext());
And change onPause and onResume like this.
#Override
public void onPause()
super.onPause(); {
if (zXingScannerView != null) {
zXingScannerView.stopCamera();
zXingScannerView.stopCameraPreview();
}
}
#Override
public void onResume() {
super.onResume();
if (checkCameraHardware(getActivity().getApplicationContext())) {
Toast.makeText(this.getActivity(), "camera hardware is free", Toast.LENGTH_SHORT).show();
zXingScannerView.setResultHandler(this); // Register ourselves as a
zXingScannerView.startCamera(0); // Start camera on resume
}
}
Also remove all these objects
private SurfaceView mySurfaceView;
private Camera mCamera;
private CameraPreview mPreview;
No need for them ,it's there in your zXingScannerView.

Actually you are not release objects when switch to other fragment first release all object in onPause() method and onResume() reconnect with camera. try this one :
#Override
public void onResume() {
super.onResume();
if (zXingScannerView!= null) {
zXingScannerView.stopCameraPreview();
zXingScannerView.resumeCameraPreview(this);
}
}
