[android-developers] Re: help needed with project: preview image on a opengl texture
couldn't fully test if it works. but why do I have to call this method, what does it acutally do? I though it was needed if you want to directly let the camera draw on an surface, like here: http://developer.android.com/guide/samples/ApiDemos/src/com/example/android/apis/graphics/CameraPreview.html But I want to draw the camera preview on an opengl object, through textures, do I really need to do that?

Re: [android-developers] Re: help needed with project: preview image on a opengl texture
On the physical device, in settings->about phone-> build_number., there's a long description there that more precisely identifies the revision of software being used. In the first software revision for Droid, for example, it will say ESD20 in the midst of that long string. Also, I'm wondering, is it sufficient to exit the application to restore the device's normal behavior? I appreciate the information if you're willing to reply. Thanks! Stephen.

You still need to do that. If applications do not call setPreviewDisplay, camera drivers may not start the preview even if startPreview is called.
