Dark Text on Document Picker Sub Action Bar

[risalfajar]

Using this code:

FilePickerBuilder
            .instance
            .setActivityTheme(R.style.LibAppTheme)
            .pickFile(this, RC_TENDER_DOCS)

I got this:

As we can see, the text in sub action bar (pdf, ppt, etc) can't be seen clearly because of the dark color.

This is the content of LibAppTheme:

    <style name="LibAppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:colorBackground">@android:color/background_light</item>
        <item name="android:windowBackground">@android:color/white</item>
    </style>
