Code:
<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<map>
<boolean name="pref_key_screen_saver_from_sdcard" value="true" />
<string name="pref_key_screen_saver_from_path">/storage/emulated/0/Screensaver/sleep.jpg</string>
<boolean name="pref_key_screen_saver_low_power" value="false" />
<int name="key_screensaver_img_index" value="5" />
</map>
I then set Calibre Companion to save my book cover to: /storage/emulated/0/Screensaver/sleep.jpg
You can change the path and the name of the .jpg to whatever you want and use whatever image you want.
