R cannot be resolved - Android error
I am having a issue which I have had before and I don't understand the cause. My project and code is fine as it was running yesterday. I have open Eclipse today and the whole project looks like it contains errors.
I believe it is some sort of build path issue. I don't understand why it randomly occurs? But in the code where there is R.Layout.LayoutName
there is an issue... can anyone help?
I have tried cleaning and building it, I have tried importing android.R but I didn't have this before, it then gives and error and says the layout file doesn't exist.
I think I found another solution to this question.
Go to Project > Properties > Java Build Path > tab [Order and Export] > Tick Android Version Checkbox Then if your workspace does not build automatically…
Properties again > Build Project
