Android developers Huawei cell phone does not pop Toast, reported HwRTBlurUtils: check blur style for HwToast-Toast ... reason

Huawei cell phone does not pop Toast, information log reported: HwRTBlurUtils: check blur style for HwToast -Toast, themeResId: 0x7f0c0005, context:. . . 
My reason is: When overriding a call setToDefaults getResources method () method caused.

Fun getResources the override (): Resources { 
        Val Resources = super.getResources () 
        Val config = resources.configuration 
// config.setToDefaults () // reason is called this line of code. . . 
        = 1.0f config.fontScale 
        resources.updateConfiguration (config, resources.displayMetrics) 
        return Resources 
    }
