I?m also facing a problem when I tried to test the android version of the
Simpleserver & Simpleclient.
I have successfully built iotivity for android platform with build script as..
?scons TARGET_OS=android TARGET_ARCH=armeabi TARGET_TRANSPORT=IP RELEASE=1?
described Readme.scons.txt file.
However, the client couldn?t find the server on the android phone.
Here are the questions..
1. In the ?BuildInstructionsForAndroidAPI.txt, it says to verify that 9
different *.so files exist
in the ~~/base/libs/armeabi/..
However, there?re only 7 so files in the directory and those are..
1. libca-interface.so
2. libconnectivity-abstraction.so
3. libgnustl-shared.so
4. liboc_logger.so
5. liboc.so
6. libotbcstack.so
7. libocstack-jni.so
What are the missing .so files, and don?t we need to have libcoap??
2. When I compare the output *.so files between linux-version &
android-version, however,
the total number of files were not the same.
Is it the expected result???
3. Are those Android version of the Simpleserver & Simpleclient working
codes?
Thank you.
Jay.
