    Hi all:
    We want to run a QT app on the android device(QCOM device),and the app may rendering 3D with opengles.
    I have a question: Is it feasible if Android and QT use GPU at the same time?

    Thanks.

      Why not? How games and other apps do that on Android?

        Thanks for reply.
        Does QT rendor 3D by using Android service?such as:SurfaceFlinger or services of OpenGLES?
        If QT calls OpenGL by itself,the Android system also calls OpenGL,there will be two opengl instances.
        I do not known if the OpenGL or GPU can works well when there are two OpenGL instances.

          That I don't know.
          You could get better answer on Qt developers mailing list.
