It seems this is thrown when a class
is visible at compile time but not at
run time... how can this happen?
The build classpath may include JARs that are not being packaged into the APK.
Is it possible or desirable to
statically bind at compile time to
avoid the problem?
It is possible, desirable, and necessary.
Outside of Eclipse, you just put the JARs you need in libs/
in your project, compile with Ant, and you are done.
Inside of Eclipse, one pattern I have had students use with success is to put the JARs you need in libs/
in your project, add them as JARs to the build path (note: not external JARs), and they get packaged as part of the APK. Note, though, that I do not personally use Eclipse, and so my experience with it is limited.
