mapping a texture on a square: Why is the image rotated?

I successfully mapped an image on a square in OpenGL ES...but its rotated 90 degrees. Im pretty new at OpenGL ES, and was wondering if someone could point out why exactly its rotated. Thanks!

vertices[] correspond to the following coordinates on the screen: lower-left, lower-right, upper-left, upper-right (in that order).

texture[] correspond to the following texture space coordinates: lower-left, upper-left, lower-right, upper-right.

You have a mismatch there; change the order in either of the arrays to match the other.

texture coords were off, the correct ones were:

    private float texture[] = {
        //Mapping coordinates for the vertices
        0.0f, 1.0f,
        1.0f, 1.0f,
        0.0f, 0.0f,
        1.0f, 0.0f, 
   };
