My activity style must be from AppCompat theme.
So I make custom style and set activity style in manifest.
But black background is shown.
Below is custom theme
<style name="TransparentTheme" parent="@style/Theme.AppCompat">
<item name="android:background">@null</item>
<item name="background">@null</item>
<item name="android:windowBackground">@null</item>
<item name="android:colorBackgroundCacheHint">@null</item>
<item name="android:windowContentOverlay">@null</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowAnimationStyle">@null</item>
</style>
