Use Reflection to allow for conditional compile. This code snippet
might help, although it shows calling setFlashMode, the concept is the
same:
Method methodSetFlashMode = null;
Class<?>[] methodSetFlashModeSignature = new Class[]
{ String.class };
List<Size> lSize = null;
try
{
methodSetFlashMode =
params.getClass().getMethod("setFlashMode",
methodSetFlashModeSignature);
}
catch (NoSuchMethodException nsme)
{
}
if (methodSetFlashMode != null)
{
Object[] oArgs = new Object[1];
oArgs[0] = "off";
methodSetFlashMode.invoke(params, oArgs);
}
