Recently I found my Android SDK source is not complete. I have downloaded the Android SDK API 16 ONLY from SDK Manager. When I want to generate the javadoc from source, it warns me that some classes are not found. I have read the website below, but I get confused whether the higher level API contains the lower level APIs. Is it enough to install the highest API only ? Or do some of the Android SDK source depend on the JDK source ? Thanks a lot.
A piece of Javadoc warnings :
./java/lang/String.java:31: warning: package libcore.util not exist
import libcore.util.EmptyArray;
