Copy Eclipse / Android Project - now errors when running it -

i have encountered odd problem after copied exclipse project.

in workspace have "my_base_project". when done, wanted create copy of project specific customer, copied folder same workspace root folder name being "my_spinoff_project".

i search , replaced text strings "com.example.base" "com.example.spinoff" in .java , .xml files. imported in eclipse , got far error free.

however, when running error:

java.lang.runtimeexception: unable instantiate application com.example.spinoff.micapp: java.lang.classnotfoundexception: com.example.spinoff.micapp

from androidmanifest.xml

so... don't understand error. can compile , run project. project halts on when running above error. have somehow missed replacing text strings somewhere?

go properties/ java build path/ libraries/ add external jars. check jar files in properties/ java build path/ order , export.
