Designed for learners of English, this groundbreaking new dictionary from North America-s foremost language experts provides in-depth and up-to-date coverage of basic English vocabulary, grammar, and usage.
Just like many other third-party apps, BlueDict is only a database "reader". So you need to get the databases (.MDX and .MDD files) then put them into /sdcard/BlueDict/Dicts or your specified path.
