 # Input Method Engine
 
-> ![icon-note.gif](public_sys-resources/icon-note.gif) **NOTE**<br>The initial APIs of this module are supported since API version 8. Newly added APIs will be marked with a superscript to indicate their earliest API version.
+The **inputMethodEngine** module streamlines the interaction between applications and input methods. By calling APIs of this module, applications can accept text input through the input methods, be bound to input method services, request the keyboard to display or hide, listen for the input method status, and much more.
