Assigning Values to Variables

While working on this part of the project I discovered that when assigning values I had to write it differently than what was shown in the video. For example in the video you simply had to put findViewById(R.Id.texView1) would get what you needed. On my version I had to write findViewById(com.example.crystalball.R.id.textView1). It seemed to work just fine. I also noticed a lot more "id"s would show after typing in the "findViewById". Is this simply because I may be running a new version of eclipse than what is in the video?

IMHO There is nothing wrong with using fully qualified package names but we don't because we want to write less! This way of specifying name is required where we have multiple classes with same name in different packages as to distinguish which class is actually being called at runtime. Other than that you would not need to write it this way. Application specific Ids are defined in R class which is a generated java file and it contains values for all id, string, drawable, style, etcetera. So all the Ids would show up as you type.
