Sometimes get android.content.res.Resources$NotFoundException

We're debugging a crash in a Cordova app that seems to happen on launch / foregrounding, after the app was backgrounded for a moderate amount of time and has been to some extent killed by the OS.
At the time of the crash the app is attempting to show a native dialog fragment for Fingerprint Authentication. For some reason in this case the resources for this fragment cannot be found.
It's been reported for Android 6 and 7, on older and newer devices.

Here's the problematic bit of code, from the DialogFragment's onCreateView:
int fingerprint_dialog_container_id = getResources()
.getIdentifier("fingerprint_dialog_container", "layout",
FingerprintAuth.packageName);
View v = inflater.inflate(fingerprint_dialog_container_id, container, false);
When the crash happens, getIdentifier(...) is for some reason returning 0. Most of the time the actual identifier is returned.
I have not found a way to reproduce the crash, and advice to enable developer options like 'Don't keep activities' and 'Background process limit' had did not help.
Thanks for any help.

Android : Window couldn't find content container view after adding file in raw folder

Comscore library was causing this issue in my case. Try removing it.

Android strange ClassCastException

A few days ago we started to receive some crash reports from users using our app, but the stracktrace is really strange. It happens only on Samsung G900f (S5) and I can't reproduce it and decide to post a question here.
The stacktrace shows this:
Caused by java.lang.ClassCastException: android.support.design.widget.CollapsingToolbarLayout cannot be cast to android.support.design.widget.CollapsingToolbarLayout

at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1183)
It is a Fragment which contains CollapsingToolbarLayout with initialization and use all correct, but not sure why this happens.
We got some other ClassCastExceptions with different classes from the same device. For example:
Caused by java.lang.ClassCastException:
com.packageName.model.VideoMeta cannot be cast to
com.packageName.model.VideoMeta
where VideoMeta is a class which implements Parcelable and this exception occurs in class Video which implements Parcelable too:
private Video(Parcel in) {
id = in.readLong();
postId = in.readString();
url = in.readString();
thumb = in.readString();
meta = (VideoMeta) in.readValue(VideoMeta.class.getClassLoader());
}
But that's not the end...
Caused by java.lang.ClassCastException:
android.support.design.widget.AppBarLayout$LayoutParams cannot be cast to
android.support.design.widget.AppBarLayout$LayoutParams
I have no idea what can cause this exception and why it's happening, that's why posting it here.
Thanks in advance for any kind of help or suggestions!

Android app crash after open other apps

I have a problem with my app. The app works perfectly. If I press the back button the app obviously closes without any problems. If I press the home button the app is in the background. If I open the app immediately this works, but if I open other apps and then I open my app often crashes.
How can I fix? I have to implement the method onPause? But how?

This cause the crash
int x = Integer.parseInt(numVoti.replaceAll("[\\D]", ""));

Firstly, your app does not go in the background, when you press the Home button. It just gets added in the Back Stack. Second, try to explain to us the resources your app uses, how they interact with other apps, possibly.
