Aard 2 for Android
Aard 2 for Android is a successor to Aard Dictionary for Android. It comes with redesigned user interface, bookmarks, history and a better dictionary storage format.
Lookup queries are punctuation, diacritics and case insensitive.
Bookmarks and History
Visited articles are automatically added to history and appear in History tab. Articles can also be bookmarked (tap Bookmark icon when viewing article). Bookmarked articles appear in Bookmarks tab. Bookmarks and history can be filtered and sorted by time or article title. Both bookmarks and history are limited to a hundred of most recently used items. To remove bookmark or history record, long tap a list item to enter selection mode, tap items to be removed, tap Trash Can icon and confirm. A bookmark can also be removed by tapping Bookmark icon when viewing article.
Dictionaries are added by selecting dictionary files using Android’s document chooser.
Note that application itself does not download dictionary files.
Opened dictionaries can be ordered by marking and unmarking them as “favorite” (tap dictionary title). Lookup results of equal match strength from multiple dictionaries are presented in the order of dictionaries in the dictionary list. Dictionaries can also be deactivated (turned off). Turned off dictionaries do not participate in word lookup or random article lookup, but are still available when opening articles from bookmarks, history or when following links in other articles. Unwanted dictionaries can also be completely removed from the program (but dictionary files are not deleted).
Dictionaries may include alternate style sheets. User may also add custom style sheets via Settings tab. Dictionary built-in and user styles appear in the “Style…” menu in article view.
Mathematical formulas in Wikipedia articles are rendered as text using MathJax - scalable, styleable, beautiful on any screen.
Tapping application logo in main activity finds a random title in an active dictionary and opens corresponding articles. User may optionally limit random lookup to only use favorite dictionaries.
Volume Buttons Navigation
When viewing articles, volume up/down buttons scroll article content or, if at the bottom (top) of the page, move to the next (previous) article. Long press scrolls all the way to the bottom (top). In main view volume buttons cycle through tabs. This behavior can be disabled in settings.
Articles can be viewed in fullscreen mode. Pull down the top edge to exit fullscreen mode.
Text from clipboard can be automatically pasted into lookup field (unless it contains a Web address, email or phone number). This behavior is off by default and can be enabled in settings.
External Link Sharing
Some dictionaries (such as Mediawiki based ones - Wikipedia, Wiktionary etc.) contain external links. Long tap on the link to share it without opening in a browser first.
Aard 2 uses local embedded web server to provide article content. This permission is necessary to run the server.
Also, articles may reference remote content such as images. This permission is necessary to load it.
User chooses when to allow loading remote content: always, when on Wi-Fi or never. This permission is necessary to determine network connection state.
Aard 2 is built with Gradle.
Aard 2 depends on projects slobj and slobber.

Launching from Other Applications
Aard 2 lookup can be initiated from other applications, either through standard Share action or directly, if application implemented an action to start Aard 2 with lookup intent.
Applications can launch Aard 2 lookup by starting activity with intent
aard2.lookup with text to look up passed as an extra string
parameter SearchManager.QUERY. For example:
Intent intent = new Intent("aard2.lookup"); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP); intent.putExtra(SearchManager.QUERY, "Foo Bar"); startActivity(intent);
Same thing from a command line using adb:
adb shell am start -a aard2.lookup -f 335544320 -e query "Foo Bar"
