I'm following a tutorial on this Lapit Chat App - All Users Activity - Firebase Tutorials - Part 14. But i get my application to be corrupted when retrieving data from firebase. For previous tutorials all goes well without error. Just for this topic my app crashes. And all my code is the same as in the tutorial.

Is there anything wrong or missing on my code? Please help
your CircularImageView is not inflated and there was so many problems about it, solution use alternative library like hdodenhof CircularImageView link
add this to your dependencies :
compile 'de.hdodenhof:circleimageview:2.1.0'
and add the view like this :
<de.hdodenhof.circleimageview.CircleImageView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/profile_image"
android:layout_width="96dp"
android:layout_height="96dp"
android:src="#drawable/profile"
app:civ_border_width="2dp"
app:civ_border_color="#FF000000"/>

I am a student who currently taking mobile application development. Although my app can run but it doesnt show any activity instead of just give me W/RecyclerView: No adapter attached; skipping layout. I dont know how to solve the issue, so I was hoping can get some guidlines from experts.

You have to create an adapter class and add with your recycler view.
The basic snippet to set adapter to recycler view is like bellow
YourAdater adapter = YourAdater();
layoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(adapter);
for more detail that how to create a RecyclerView AdapterClass you can see this or this
I am working on this application and I'm trying to show my "expenses" database data in my personal fragment. I have created a recycler view file to replace the default layout. I am struggling to make this work. Can anyone help with the FirebaseRecycler Adapter and the holder class? I am not able to make this work, my fragment display the default layout with no information. I have tried and follow some codes but it is not working.
here is my personal fragment where the recycler view should appear

I believe you are missing these two main code.
Set adapter.startListening() inside onStart()
Set adapter.stopListening() inside onStop()
Make sure to put the code before the scope end of onStart() as you are performing a lot of operations and setting your adapter above.
Would like to know how to create a NavigationDrawer within a Fragment (in this case my HomeFragment) and NOT in an Activity. Have seen everything on how to create a NavigationDrawer within an Activity, such as MainActivity, but my goal for this project is to create a NavigationDrawer ONLY for the HomeFragment. Don't want any of the other fragments to contain it. The drawer_menu will contain Edit Profile, Settings, and Log Out. Below I have posted what I have done... Is there a better way to do it? Code seems to be a bit awkward.
Every video I have seen, every post has been about creating a NavigationDrawer in Activities, so I'm wondering what the code would look like for Fragment. I tried doing it just like you would for Activity, but it wouldn't work.
Below you guys have my HomeFragment.java and fragment_home.xml

It's not possible.
Because To implement the Navigation Drawer we first need to add android.support.v4.widget.DrawerLayout as the root of the activity layout.
For Toggle Option of Navigation Drawer, We Require ToolBar.
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar,
R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawerLayout.addDrawerListener(toggle);
The ToolBar is not possible in the fragment.
For Better use, Make Navigation View in Activity inside the DrawerLayout.
I wanna have same fab transformation behavior as shown in
Material Website in Full Screen (or morph) section.
I have tried default FabTransformationScrimBehavior and FabTransformationSheetBehavior. but scrim behavior doesn't do anything and sheet behavior don't animate just like I wanted and also it reduce the elevation of the fab to value 0f. and I haven't found any way to unexpand fab. and I wanna know how to use fab transformation behavior. Actually I didn't find any doc on how to use it. So Please help

For the FabTransformationSheetBehavior to work, you need to change the isExpanded value.
on change of this value, expand and collapse animation will be called and visibility of the linearlayout and fab button will be handled automatically. Don't change visibility manually as this would block transformation animation.
Use back button to transform back to FAB.
val fab: FloatingActionButton = findViewById<FloatingActionButton>(R.id.fab)
fab.setOnClickListener { fab.isExpanded = !fab.isExpanded } // this sets isExpanded as true
val back = findViewById<ImageButton>(R.id.back)
back.setOnClickListener{ fab.isExpanded = !fab.isExpanded } // this sets isExpanded as false
My Android listview does not update with notifydatasetchanged() call.

I cannot see the updated list in the main activity eveb though in onResume I used notifydatasetchanged() function.
Try This....
#Override
public void onResume() {
super.onResume(); // Always call the superclass method first
Log.d("jokesbook", "onResume ");
notifyDataSetChanged();
}
