Google Now API adds additionals commands to the search and makes it even bigger. It's like an extension to the Google Now. Let's see how this all works.
First of all, this is an xposed extension - to get this to work you're going to need the Xposed Framework. If you don't have it already, check this post to install it, it's really easy!
As you can see on the pictures above, the app offers a simple and nice interface with basic settings -
Prevent duplicate searches - This prevents (as the name says) from duplicate searches, which can be useful for some of you - you can experiment with that and you'll see.
Delay commands for GEL - You gotta get this checked if you're using the GEL (Google Experience launcher).
The whole app works on plugins - that's something like modules for Xposed Framework. Plugins are needed in case you want to get any extension, otherwise the app has no sense (it cannot really do anything without plugins).
As the app development has just begun, there aren't many plugins right now but I'm sure there will be more very soon. Now, you can get a little "preview" of these:
- Music Controls: Control music playback. Supported commands: "play/pause/resume music", "play songs by <artist>", "play song <title>", "next/previous track/song", "volume up/down/max", "what song is this" opens in Shazam (Shazem required for this action).
- Voice Toggles: Turn on/off Wi-Fi, Mobile Data, or Bluetooth.
- AZLyrics Viewer: Shows lyrics for songs from AZLyrics.com. Supported commands: "show lyrics for <song> by <artist>", exact syntax required here, artist is not optional.
- Autovoice, runs Tasker commands from Google Search.
