MultiLing Keyboard is an Android keyboard that stands out for two main reasons: it's extremely lightweight, taking up less than one megabyte of memory, and it has a stunning number of different languages available, though you have to download them separately to use them.

Other interesting features in MultiLing Keyboard include gesture shortcuts and the ability to add new words to the dictionary. It even includes unique features for tablets, letting you separate the keyboard so you can handle it more smoothly.
