Controlling Display Refresh Rate on Android Device
<p>Not yet a developer, just trying to find out if an android app can do what I need..</p>

<p><strong>What I need:</strong></p>

<p>Simple app that displays a full frame of a single color onscreen at a certain intensity at a fixed frequency! I need it for a synchronization purpose with as high a resolution as possible (achieved by changing an intensity in a known pattern with as high a fixed frequency as possible).</p>

<p><strong>What questions I have:</strong></p>

<ol>
<li><p>Does an android device run with a
fixed display frequency or is there
any way to set it to a fixed
frequency of say 60fps?</p></li>
<li><p>If the fixed frequency can be
achieved, is there a vsync interrupt
or something similar that lets me
change the intensity on the screen
at the right time.</p></li>
<li><p>If the above two things can be
achieved, which approach do I need
to take. I'm thinking I need to look
at OpenGL ES and perhaps NDK....
Could anyone please point me in the
right direction....</p></li>
</ol>

<p>TIA,</p>
