Hello, I am getting this error after I update the library:

I just changed this code:

mBottomBar = BottomBar.attachShy((CoordinatorLayout) findViewById(R.id.bottom_coordinator),
findViewById(R.id.nested_scroll), savedInstanceState);
mBottomBar.noTopOffset();
mBottomBar.noTabletGoodness();
mBottomBar.noNavBarGoodness();
mBottomBar.setItemsFromMenu(R.menu.bottom_tabs, new OnMenuTabClickListener() {
@OverRide
public void onMenuTabSelected(@idres int menuItemId) {
temp = (ViewGroup) findViewById(R.id.main_view);
...

to this:

...
mBottomBar.setItems(R.menu.bottom_tabs);
mBottomBar.setOnMenuTabClickListener(new OnMenuTabClickListener() {
@OverRide
public void onMenuTabSelected(@idres int menuItemId) {
temp = (ViewGroup) findViewById(R.id.main_view);
...

I thought that this is all I supposed to do, any help is greatly appreciate. Thanks

Will fix. Thanks.

Same thing happens to me on this line:

mBottomBar = BottomBar.attachShy((CoordinatorLayout) findViewById(R.id.coordinatorLayoutMain), findViewById(R.id.myScrollingContent), savedInstanceState);

if i comment this line, app stops crashing, maybe it will help you. Version 1.3.6

[roughike]

I couldn't replicate the issue, but @rmnbhl and @mag2007, can you test if it still exists in version 1.3.7?

[mag2007]

@roughike it does not crash any more. Thanks! But the bottombar does not hides either. I will look, maybe i missed something.

[rmnbhl]

It works well now, also no problem with hiding. Thanks!
