[Android] com.meizu.widget.OverScrollerExt cannot be cast to android.widget.OverScroller

[alexHlebnikov]

Hi, I have a problem with my app on Meizu MX2 (Android 4.4.4).

After my app launches and I'm trying to open menu or do any other action in my app, I've got this error:

It's in debug mode, in release mode my app just silently crashes.

I googled a lot and here are the things I have tried:

• add android:overScrollMode="never" to maps.xml:

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    ...
    android:overScrollMode="never"
    ... />

It doesn't helps.

• add the following to styles.xml:

<resources>
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="android:overScrollMode">never</item>
        <item name="android:listViewStyle">@style/Widget.AppTheme.ListView</item>
        <item name="android:scrollViewStyle">@style/Widget.AppTheme.ScrollView</item>
    </style>

    <style name="Widget.AppTheme.ListView" parent="android:Widget.ListView">
        <item name="android:overScrollMode">never</item>
    </style>

    <style name="Widget.AppTheme.ScrollView" parent="android:Widget.ScrollView">
        <item name="android:overScrollMode">never</item>
    </style>
</resources>

It doesn't helps.

Maybe someone can help me.

There is custom firmware installed by default on Meizu phones - Flyme OS (on MX2 it's Flyme OS 4.2.8.2i).
I think the problem is connected with it.

I'm using RN 0.33.0.RC.0, MacOS 10.11.6.

i have the same problem. have you solved?

[sidgwick]

I have this problem too.

It seems that this error occurs only on Meizu devices, My code run well on simulator.

[alexHlebnikov]

I'm still have no solution for this :(
I think we need sombody from RN developers to solve this problem.

I have the same problem when I upgrade 0.33 from 0.31

[alexHlebnikov]

It's also on 0.34.RC.0.

Same issue.

No time to wait for official update. Workaround for me is to privide a fixed ReactScrollView to my front-end team.

Fix is something like this:

        if (sScrollerField != null) {
            try {
                Object scroller = sScrollerField.get(this);
                if (scroller instanceof OverScroller) {
                    mScroller = (OverScroller) scroller;
                } else {
                    mScroller = null;
                }
            } catch (IllegalAccessException e) {
                throw new RuntimeException("Failed to get mScroller from ScrollView!", e);
            }
        } else {
            mScroller = null;
        }

Tested on several Meizu devices and just worked well. Waiting for the official update.

@janicduplessis this problem seems still exist on v0.34.0-rc.0.

[nihgwu]

It should be irrelevant with the RN, most likely the Flyme OS extends the official ScrollView (for bouncing?) I don't have a device by Meizu to verify though.

You can contact some Flyme OS developers to investigate this issue: https://github.com/flymeOS.

@nihgwu but version 0.31 is ok, so i think it could be modify something what cause this problem

[nihgwu]

@zackteng then you can compare the branches to locate the commit which result this regression, since witch release

[leeight]

It was fixed by this commit: 5deb528

[janicduplessis]

Closing this since it was fixed.
