Using a file manager application, extract the plugin zip-file. In some cases this will create a directory with the same name as the .ZIP file, minus the zip extension. If this is the case, inside of that directory is the relevant plugin information.

In the case of DroidButtons you may get something like this

droidbuttons-2.1.0/
      droidbuttons/
           images/
                Lock.png
                Lock_disabled.png
                Open_lock.png
                Open_lock_disabled.png
           main.lua
           functions.lua
           templates.lua
           ui.lua
           ui_edit.lua
           vars.lua

Before going any further with the plugin files, first we need to make sure the plugin installation location is created. Directory names are case-sensitive and must be typed exactly as they are shown.

Find the directory: Android/data/com.guildsoftware.vendetta/files
Inside of the files directory create a directory named plugins

Now go back to where you extracted DroidButtons to and copy the inner droidbuttons folder (the one that has all of the .lua files directly inside of it). Paste this folder into the plugins folder you just created.

You should now have something like the following:
Android/data/com.guildsoftware.vendetta/files/plugins/droidbuttons/main.lua

Now restart your device or reload the interface.

bump. please sticky Whistler and unsticky the other one.

In the interest of wider awareness of mobile plugin installations, I am making a very comprehensive guide available to non-FAMY members with screenshots.
