draw bitmap using Opengl es in Android
<p>I have an android application that is drawing a 800*480 image on the screen. My phone is also 800*480 px. The phone is able to do the drawing in about 25 ms. Every few seconds i want to transition to another image which is also 800*480 by fading the alpha of the first image and increasing the alpha of the second image. While doing this the drawable.draw(canvas) call takes about 75 ms.</p>

<p>What can i do to reduce the drawing time during the transition phase? I have considered using OPENGL but i cannot figure it out. Any help is appreciated.</p>
