Problems on Android with new version Unity 2017.1.1f1

Hello,I used 2017.0.1 so long time. Now I updated my Unity and there are many problems:

Android:
Add manifest file in Plugin/Android folder.Also add res/value folder with style.xml and color.xml
in color.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="bg">#FF5A7D7F</color>
</resources>
------------------
in style.xml
<?xml version="1.0" encoding="UTF-8" ?>
<resources>
<style name="CustomTheme" parent="@android:style/Theme.Material.NoActionBar.Fullscreen">
<item name="android:windowBackground">@color/bg</item>
<item name="android:textColor">#000000</item>
<item name="android:textColorPrimary">#000000</item>
<item name="android:textColorSecondary">#000000</item>

</style>
</resources>

----------------------

In manifest:
....
<activity android:name="com.unity3d.player.UnityPlayerActivity" android:theme="@StyLe/CustomTheme"
android:label="@String/app_name">
...

on 2017.0.1 works!
on 2017.1.1 started and look like maximize animation and on short moment blink black color.

Where I may fix this problem?

Second Problem: Font changed in keyboad's textfield.
I try
https://stackoverflow.com/questions...ustom-font-for-a-whole-application-in-android
but Unity write:

stderr[
invalid resource directory name: F:\TESTPROJ\New Unity Project\Temp\StagingArea\android-libraries\unity-android-resources\res font
]
stdout[

]

HALP PLEASE
