i'm a bit stuck in this task. I have an app which displays a main fragment embedding google maps, now i would like to replace it with another fragment showing some charts when the user clicks a send button inside a drawer menu list.
When i click send application get stuck, giving me the hated "Application Not Responding". However, if i change the android:name field into the same of the maps fragment, it works and display the map correctly.
Main activity snippet where i launch maps fragment
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
if (toolbar != null) {
setSupportActionBar(toolbar);
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.activity_main);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
mapsFragment = new MapsFragment();
getSupportFragmentManager().beginTransaction()
.add(R.id.maincontainer,mapsFragment)
.commit();
navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
Main Activity snippet where i launch the charts fragment
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
Snackbar snackbar;
Fragment fragment = null;
switch(item.getItemId()){
case R.id.nav_manage:
snackbar = Snackbar
.make(coordinatorLayout, "manage", Snackbar.LENGTH_LONG);
snackbar.show();
break;
case R.id.nav_share:
snackbar = Snackbar
.make(coordinatorLayout, "share", Snackbar.LENGTH_LONG);
snackbar.show();
break;
case R.id.nav_send:
snackbar = Snackbar
.make(coordinatorLayout, "send", Snackbar.LENGTH_LONG);
snackbar.show();
fragment = new ChartsFragment();
break;
case R.id.nav_view:
snackbar = Snackbar
.make(coordinatorLayout, "view", Snackbar.LENGTH_LONG);
snackbar.show();
break;
}
if(fragment != null){
getSupportFragmentManager().beginTransaction()
.replace(R.id.maincontainer,fragment)
.commit();
}
// Highlight the selected item has been done by NavigationView
item.setChecked(true);
// Set action bar title
//setTitle(item.getTitle());
DrawerLayout drawer = (DrawerLayout)
findViewById(R.id.activity_main);
drawer.closeDrawer(GravityCompat.START);
return true;
}
MapsFragment onCreate
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_maps, container, false);
SupportMapFragment mMapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map);
mMapFragment.getMapAsync(this);
mContext = getActivity();
return rootView;
}
ChartsFragment onCreate
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_charts, container, false);
return rootView;

I already tried to replace
android:name="com.fabio.gis.geotag.ChartsFragment"
with
class="com.fabio.gis.geotag.ChartsFragment"
Nothing changed.
Thanks in advance for your support. I realize i'm a beginner in android, maybe i'm struggling for just a stupid rookie mistake.
After a while it remain in ANR it gave me the following stacktrace error
