This crash has only been reproducible in Android 8/8.1 for me. This also only happens in obfuscated builds, unobfuscated builds are not affected. I have tried adding keep rules for the entire codebase and all dependencies and it does not fix the crash, but -dontobfuscate does.
On first launch, the app works fine and when you click a spinner, it pops up the SelectPopupAdapter dialog. On second launch, the same spinner will crash the app if selected. Clearing the app data makes the spinner work again.
The class is a fairly simple webview:
public class WebViewActivity {
#BindView(R.id.web_view)
WebView webView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_web_view);
ButterKnife.bind(this);
setupWebSettings();
webView.setWebViewClient(new CustomWebview());
webView.postUrl(url, postData.getBytes());
webView.setOnKeyListener((v, keyCode, event) -> {
if (event.getAction() == KeyEvent.ACTION_DOWN) {
WebView webView = (WebView) v;
switch (keyCode) {
case KeyEvent.KEYCODE_BACK:
if (webView.canGoBack()) {
webView.goBack();
return true;
}
break;
}
}
return false;
});
}
private void setupWebSettings() {
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setBuiltInZoomControls(true);
webSettings.setDisplayZoomControls(false);
webSettings.setLoadWithOverviewMode(true);
webSettings.setUseWideViewPort(true);
}
#Override
public void onDialogPositiveClick(DialogFragment fragment) {
fragment.dismiss();
finish();
}
#Override
public void finish() {
setResult(RESULT_OK);
super.finish();
}
private class CustomWebview extends WebViewClient {
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
//logging
}
}
}
Here is the crash log:

Its a fun bit of code that I just wrote, and I am new to android or programming in general, so I cannot figure out what's wrong.
Any help is appreciated.
I don't know what's causing it.
Try using "selectedItemView: View?" instead of "selectedItemView: View" in your arguments in onItemSelected callbacks and see what happens. The methods expect selectedItemView to have nullable type.
I'm trying to get a LiveData Observer to work, and everything was working, but after a week my app keeps crashing when attaching the fragment to my activity with the live data. The fragment is very simple, it has a RecyclerView that displays a list of Bloggers in a grid. The ViewModel is the following:
class SimpleBloggersViewModel : ViewModel() {
var bloggers: MutableLiveData<List<Blogger>> = MutableLiveData()
}
And I initialize it in my fragment using:
private val viewModel: SimpleBloggersViewModel by lazy {
ViewModelProvider(this).get(SimpleBloggersViewModel::class.java)
}
The code that causes the crash is the following:
override fun onAttach(context: Context) {
super.onAttach(context)
try {
viewModel.bloggers.observe(viewLifecycleOwner, Observer { changeObserver })
} catch (e: IllegalStateException) {
Log.e(TAG, "onAttach: Failed to attach BloggersFragment.", e)
}
}
Without the try/catch in the onAttach method, I get the following cryptic exception (and an app crash)

After adding the try/catch block you see above, the exception ahs a little bit more info, but I still can't figure out what causes the problem.

Please note that I call super on all of the overriding methods, before doing anything else, so the second exception still doesn't help me figure the bug out. Any help is greatly appreciated. Thank you for your time.
I'm getting an error in the title. Application I also have a mixed structure and use a few nested structures.
There is a structure like " CategoryFragment -> ViewPager -> RecyclerView inside CategoryDetailsFragment -> ViewPager-> HeadlinePagerFragment"
when changed to CategoryFragment then return to back will be this error.
CategoryFragment
val adapter = CategoriesPagerAdapter(activity?.supportFragmentManager!!,list as List<MutableMap<String,String>>)
vp_categories_pager.adapter = adapter
tl_categories.setupWithViewPager(vp_categories_pager)
CategoryDetailsFragment
This class use recyclerview and usage inside of childview viewpager.
rv_category_details.adapter = ContentAdapter(
context!!,this#CategoryDetailsFragment(usage as fragment),
this#CategoryDetailsFragment)
-> Adapter
vp_headline.adapter =HeadlineAdapter(
fragment?.childFragmentManager!!,
items, itemClickListener)
tl_headline_indicator.setupWithViewPager(vp_headline)
HeadlineAdapter
class HeadlineAdapter(
fragment: FragmentManager,
var list:MutableList<MutableMap<*,*>>,
val itemclickListener:ContentAdapter.Itemclicklistener)
:FragmentPagerAdapter(fragment){
override fun getItem(position: Int): Fragment =
HeadlinePagerFragment(PutData(mutableMapOf(
'm' to list[position],
'l' to itemclickListener
)))
override fun getCount(): Int = list.size
override fun getItemPosition(`object`: Any): Int {
return PagerAdapter.POSITION_NONE
}
}
Return this error
No view found for id 0x7f0901de (com.bursadabugun.android:id/vp_headline) for fragment HeadlinePagerFragment{17872d5 (85c9643d-c164-417e-a428-7105105970a1) id=0x7f0901de android:switcher:2131296734:0}

Found the solution
I added getItemId function CategoriesPagerAdapter
override fun getItemId(position: Int): Long = View.generateViewId().toLong()
I'm trying to set margin dynamically for a scroll view,
Surprisingly, my code is returning FrameLayout.layoutParam instead of ScrollView.LayoutParam here is my code, which is causing Class Cast Exception
ScrollView.LayoutParams scrollViewParam = new ScrollView.LayoutParams(ScrollView.LayoutParams.MATCH_PARENT, ScrollView.LayoutParams.MATCH_PARENT);
scrollViewParam.setMargins(0, 0, 0, 500);
scrollView.setLayoutParams(scrollViewParam);
here is the stacktrace
java.lang.ClassCastException: android.widget.FrameLayout$LayoutParams cannot be cast to android.support.constraint.ConstraintLayout$LayoutParams

So, What is wrong with my code?
Every view has layout params associated with it's parent ViewGroup.
In your case, your ScrollView must live inside a ConstraintLayout (or a subclass of it). So, when you try to set it's layout params, it'll be expending an instance of a ConstraintLayout.LayoutParams.
Change your code with this and it should work just fine:
ConstraintLayout.LayoutParams scrollViewParam = new ConstraintLayout.LayoutParams(ConstraintLayout.LayoutParams.MATCH_PARENT, ConstraintLayout.LayoutParams.MATCH_PARENT);
scrollViewParam.setMargins(0, 0, 0, 500);
scrollView.setLayoutParams(scrollViewParam);
I have a problem with the use of RecyclerView, precise that the problem occurs only in onCreateView of a class with extension Fragment.
public class LiveAction extends Fragment {
...
private List<Live> displayList = new ArrayList<>();
private RecyclerView recyclerView;
private LiveAdapter lAdapter;
#Override
public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View inflatedView = inflater.inflate(R.layout.content_main, container, false);
...
lAdapter = new LiveAdapter(displayList);
//here the problem:
RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext());
recyclerView.setLayoutManager(mLayoutManager);
recyclerView.setItemAnimator(new DefaultItemAnimator());
recyclerView.setAdapter(lAdapter);
I've already tried to replace getApplicationContext () with getContext (), getActivity (). GetApplicationContext () and others, at most I get another error (for example using getActivity (). GetApplicationContext ()): "Method invocation get 'getApplicationContext 'may produce' java.lang.NullPointerException '... ".
Where am I wrong?
