tl:dr Getting error: Java Build Path Problems - Archive for required library: library in project cannot be read or is not a valid ZIP file. This happens for two (~.so) I have included in the build path of an android project being developed in Eclipse. Am I doing something wrong by including the ~.so in the build path?
I am trying to install the SPen SDK in my android project and I am having problems with including some of the native library files (~.so).
I am trying to follow the tutorial specified here: Adding S Pen library to android project. It is point 2-2 on this page.
I include the libspen22.jar to the build path which seems to be fine. But when I tried to run the application I get an error saying Java problems, with a list of 323 items stating that function foo must override a superclass method. I had noticed however that I hadn't included the ~.so libraries to the build path so I preceeded to add these two libraries to the build path as well. Which stopped the 323 errors but caused 2 new ones - Java Build Path Problems - Archive for required library: library in project cannot be read or is not a valid ZIP file. Am I doing something wrong by including the two ~.so files in the build path for the android project being developed using Eclipse?
Go to Project Properties and set Java Compiler to 1.6 it should help.
I don't think you need any *.so for S-Pen
Anyway, you should not include *.so in your Build Path. Any prebuilt *.so should be specified in your Android.mk like this:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := foo-prebuilt
LOCAL_SRC_FILES := libfoo.so
include $(PREBUILT_SHARED_LIBRARY)
Please, refer to Android NDK docs/PREBUILTS.html But again I think it's because of Java Compiler having been set to 1.5
