Embedded Wizard is used to create GUI applications independent from the desired target and independent from the available graphics API. In case of Android, OpenGL ES 2.0 is used as graphics subsystem. This means, all graphical operations that are needed to create a certain user interface are executed by the OpenGL ES 2.0 API.
However, this does not imply that Embedded Wizard Studio provides any OpenGL functions. Due to the platform independent approach, there is no underlying graphics API accessible.
Let me recommend to study the Basic Concepts and our Tutorial in order to get familiar with Embedded Wizard.
