setSceneMode

Check Scene. But My NexusOne is not suppoert SceneMode.
getSceneMode() = null. This article is just information.

Check SceneMode now.

Camera.Parameters param = camera.getParameters();
Log.d("camera", "now = " + param.getSceneMode ());

Check supported SceceMode.

Camera.Parameters param = camera.getParameters();
List< String > modelist = param.getSupportedSceneModes ();

for (int i=0;i < modelist.size();i++) {
 Log.d("camera", "type= " + modelist.get(i));
}

Set ScenceMode.

Camera.Parameters param = camera.getParameters();
param.setSceneMode(modelist.get(mode_counter));
camera.setParameters(param);
