There are only a few reasons you will ever get this error:

  1. The class genuinely doesn't exist. If you are using code from an official example and getting this, make sure you have the latest build of the library
  2. You have not added the jar to your build path. To fix this, right click on the jar in Eclipse, and do Build Path ► Add to Build Path.
  3. Your jar is not in the /libs folder. This happens when you have added the jar to the build path, but newer versions of ADT need it to be in /libs. Put it there and re-add it to the build path.
  4. Your JAR file must be build compatible for Android (actual Java 7 compiled classes are not supported!).

See this thread. They seem to be describing a problem very similar to yours. Maybe you lack some permission in your manifest for the activity you are trying to start?

Remember always put all external jars in your apps libs. create libs folder where AndroidManifest.xml exists. Then refresh your project in eclipse. Then do as follows:

  1. Right click on your project in Eclipse
  2. click on properties.
  3. on properties window click on JavaBuildPath
  4. select Libraries tab
  5. click AddJARs button & add the external jars from your project's lib
