Error is at line 18 at xml file. Read error logcat carefully. Check your xml file — Arahasya, Oct 26 '18 at 08:38
there is no line no 18 in my xml actually that error coming from leanback library class — Chandrakant Kondke, Oct 26 '18 at 09:01
I resolved the issue. We have to set theme as @style/PreferenceThemeOverlay.v14.Leanback for the host activity — Chandrakant Kondke, Oct 26 '18 at 09:20

I solve this issue by changing theme preference Theme.Leanback

On your manifest file :

<activity android:name=".ui.setting.YourSettingPrefActivity"
        android:exported="true"
        android:theme="@style/Theme.Pref.LeanbackPreferences"/>

And here on styles.xml

<style name="Theme.Pref.LeanbackPreferences" parent="Theme.Leanback">
    <item name="preferenceTheme">@style/PreferenceThemeOverlay.v14.Leanback</item>
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:backgroundDimEnabled">true</item>
    <item name="android:colorPrimary">@color/fastlane_background</item>
</style>
