RecyclerView inside ScrollView causes runtime exception

aajakey commented 3 years ago

Killing the app through logcat and opening it again throws this exception

The problem is in the xml layout, specifically the id of the RecyclerView. Removing it no longer causes the exception.

<com.factor.bouncy.BouncyNestedScrollView
        android:id="@+id/nested_scroll_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:damping_ratio="DAMPING_RATIO_LOW_BOUNCY"
        app:fling_animation_size=".2"
        app:layout_behavior="com.google.android.material.appbar.AppBarLayout$ScrollingViewBehavior"
        app:overscroll_animation_size=".2"
        app:stiffness="STIFFNESS_LOW">

        <LinearLayout
            android:id="@+id/linear_root"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">

            <androidx.recyclerview.widget.RecyclerView
                android:id="@+id/recycler_view"
                android:layout_width="match_parent"
                android:layout_height="181dp"
                android:nestedScrollingEnabled="false"
                android:orientation="horizontal"
                android:overScrollMode="never"
                android:paddingHorizontal="20dp"
                android:paddingVertical="10dp"
                app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
                app:reverseLayout="false" />

                ...

        </LinearLayout>

    </com.factor.bouncy.BouncyNestedScrollView>

I also have the same issue, however, removing the recycler view's ID didn't solve the exception in my case. My app works fine with it and I have no issues during build time nor runtime. The exception occurs when the app is running for a larger amount of time in the background and the Android OS claims it's resources, i.e. the app state is stored. Next time the app is launched, the exception occurs during restoration of the state.

My XML structure is the same as above, the only difference is that I used a Relative instead of a Linear Layout.

It was really hard to pinpoint where this exception comes from, since the stack trace doesn't point to the library at all (see full trace below).

I was able to repeatedly reproduce this issue by enabling the "Don't keep activities" option in Settings - Developer options - Section Apps.

Unfortunately I couldn't find a workaround for this and had to remove the library from the app for now.

Here is the stack trace of the exception:

I've run into a similar issue, but it seems that my exception is slightly different.

Especially interesting is this line: Caused by: java.lang.IllegalArgumentException: Spring stiffness constant must be positive.
