[SOLVED] JW Library App on Android Does Not Show Media and Calendar Icons

Sometimes, this is due to bad cache of the app. To solve this:

(1) Go to "Settings", "Applications", find the app "JW Library"
(2) Under "Application Information", find the section "Cache", tab on "Clear Cache"*

*"Clear Cache" is different from "Clear Data". Cache is just temporary system data. However, "Data" includes your downloads and annotations which are your personal data.

If the above simple steps does not fix the problem, try restart your device. Usually this is by press and hold the power button. Then, choose restart/reboot.

If restarting your device does not help, you may really need to uninstall and then reinstall your JW Library app. If you have apps like Clean Master, after you uninstall your JW Library, you may be asked to clear data or delete data of JW Library, try NOT to delete your data, which include all your highlight comments to the publications.
