That's a pretty concise explanation of the difference between 1.6 and
2.0.

In <= 1.6, if the verifier couldn't find a field or decided that you
didn't have access to a package/private method, it would reject the
entire class immediately.

In >= 2.0, the verifier inserts an "always throw" instruction and
verification continues.  Nothing fails unless you actually try to
execute the code in question.

It looks like xcxin.mysecret.mainSecretActivity.processContact() is
attempting to access a static field
android.provider.ContactsContract.CommonDataKinds.Phone.CONTENT_URI
that didn't exist in 1.6.  (In fact, I don't think ContactsContract
existed in 1.6.)
