Make sure that "Android Private Libraries" is checked for Export.

If you've added any libraries from the libs/ folder, remove them as they are automatically added in the "Android Private Libraries" section.

In MainActivity class: import com.example.hcpandroid.SSLAuthenticate; Then After that if you have imported external library jar file import them to the LIB folder.

Right Click Your Project -> Properties -> Java Build Path -> Order and Export -> Select All -> Press OK -> go clean your project.
