ViewBinding stopped working with proguarded builds about viewbindingpropertydelegate

[kirich1409]

I've just found out the problem. Will be fixed in next release. As temporary solution please add to you ProGuard config next lines

-keep,allowoptimization class * implements androidx.viewbinding.ViewBinding {
    public static *** bind(android.view.View);
    public static *** inflate(...);
}

I had a similar problem (v1.4.4) and in version 1.4.5 everything works well.

Check version 1.4.5

Getting same issue in 1.5.8.

Getting same issue in 1.5.8.

Show me the stacktrace and the code with usage of ViewBinding in that place

Here is the stacktrace.

When I tried 1.4.5, it was working fine, but getting the issue in 1.5.8.

Update: Hey, just found that it is working on 1.5.6 too. But I'm still getting crash on 1.5.8.

-keep,allowoptimization class * implements androidx.viewbinding.ViewBinding {
public static *** bind(android.view.View);
public static *** inflate(...);
}

This worked. Thanks

There is a similar crash in 1.5.9 as well:

Caused by: java.lang.NoSuchMethodException: my.project.databinding.MiisFragmentShowcaseBinding.bind [class android.view.View]

Adding the proguard rules helps:

-keep,allowoptimization class * implements androidx.viewbinding.ViewBinding {
    public static *** bind(android.view.View);
    public static *** inflate(...);
}
