Extension compatibility

Katari comes with no extensions; they come from the stores you add, as in Extension stores. An extension loads when it was built with one of these library versions:

Extensions	Built with	Versions
Katari extensions	Entry SDK	4.0
Mihon and Tachiyomi extensions	extensions-lib	1.6
Aniyomi extensions	extensions-lib	14, 16, 17
LNReader plugins	lnreader-plugins	3.0

An extension's version usually starts with its library version, so 1.6.12 means extensions-lib 1.6. LNReader plugins are numbered on their own, so Katari takes their library version from their store's address. Browse › Extensions › ⋮ › Extension compatibility shows this list for the Katari you have installed.

Under Browse › Extensions, extensions that can't be used are listed under Not loaded:

Shown as	What to do
Unsupported SDK	It was built with a library version not in the list above. Select it: when it's older, update the extension from its store; when it's newer, a newer Katari may load it.
Torrents only	It finds episodes only as torrents, which Katari can't play. Use another extension.
Untrusted	Select the shield and Trust if you trust where it came from.
Damaged	An extension from a store that doesn't sign them changed since it was installed, so it isn't run. Select it and Reinstall.
Filtered	Its content warning is one you didn't allow. Change Allowed content warnings under Settings › Browse.
Conflict	Another installed extension provides the same sources. See Troubleshooting.
LinuxNot on desktop yet	It needs a part of Android that Katari doesn't have on Linux yet, and its info says which. Use it on Android, or wait for a Katari update.
No label	Select the info button for the reason. Usually updating the extension or Katari helps.

A store's extensions with Unsupported SDK or Torrents only are listed with the same label, but can't be installed.

Stores of LNReader plugins don't sign what they offer, so adding one asks first. What you install from such a store is labelled Not signed:

• Katari runs it in a sandbox with time and memory limits, and checks its file against the one you installed before running it. Its info screen shows the file's SHA-256.
• It can still use your logins on sites you opened in Katari's WebView, and send what you type into its settings anywhere. Only add stores you trust.
• Its updates come only from the store you installed it from. Installing another store's copy asks before replacing it, and keeps your library, settings and logins.
• Its content warning is Not rated, since the store doesn't say whether it has 18+ content. Not rated is allowed at first; turn it off under Settings › Browse › Allowed content warnings to hide them from the store's list.
