Hi all, Thanks for your reply.
Security will be one concern but , my plan is to load the required .jar files in the sdcard only when it is necessary and I will remove that .jar files from the /sdcard when my application execution completes. I want to do this because I wanna run different things, those will be decided at runtime. I think this is same concept as that of .dll ( Dynamic link Lib) in the .net framework.
