(Android™) Zip Append Files Verbose Logging

An application can check verbose LastErrorText if the zip.AppendFiles method does not append the expected files, or if it appends nothing.

    // time understanding what happened, then turn on VerboseLogging and have a look at it.
    // Make sure to turn off VerboseLogging for production because it could slow down your application.)
