I get:

Error: java.lang.NoClassDefFoundError: org.postgresql.Driver

pls help... postgresql version 9.3
*JDK 1.8
Eclipse and SDK oficial*

Now I get the following error message: java.lang.VerifyError: org.postgresql.Driver and the driver is in the "libs" folder

Well, have you downloaded and put the Postgres JDBC driver on your class-path? — Chris Mantle

You should check if your postgres driver library is in your buildpath, and if so also enable its export in the application. This is a duplicate of JDBC postgresql driver not found in android project
