Thanks a lot four your answer!
I see that this function is supported since API level 5.
When I try to call it from the emulator running level 5 and higher I
always receive a null-list back when asking for
getSupportedPictureSizes. This is a bit inconvenient but I can work
around that. I keep my fingers crossed and hope it will work on a
Nexus :-)
In order to support also lower API levels, I changed my code to this:
...
try { //check if method is available
Camera.Parameters.class.getMethod("getSupportedPictureSizes", new
Class[] { });
} catch (NoSuchMethodException nsme) {
return someDefaultSize;
}
List<Size> supportedSizes = parameters.getSupportedPictureSizes();
...
/* Evaluate best fitting size and return it */
I am wondering if this is good practice. I also read this artical
about the compatibility topic:
http://developer.android.com/resources/articles/backward-compatibility.html
But I didn't manage to apply the there proposed solution "Using
reflection" with a cached method to this problem....
