android - Application closing once started -

i got code compile, gets closed every time start it. can advise me wrong?

below manifest , logcat , top half of code in activity.

this application project done 1 coder. using native library. had compiled native library using cygwin. able compiled successfully. error "could not load needed library 'libiconv.so' 'libexif2.so' (load_library[1108]: library 'libiconv.so' not found) 01-20 14:08:19.791", had checked, these 2 files has been generated. there place else need place library file to?

it seems problem compiler cannot find libraries. project or downloaded internet? if net should check if project uses native code (does have smth jni folder .c, .cpp or .h files?). if yes, should @ first build native part , after can create build of code.
