Constructor refers to missing type context

Question

I have written a class with the following constructor

public CustomDialog(Context context)

But when I try to do this in my activity

CustomDialog diag = new CustomDialog(getApplicationContext()){/*stuff here*/};

I get the error The constructor CustomDialog(Context) refers to the missing type Context

What does this mean? And how do I fix it?

Solution 1

What does this mean?

AFAIK, either:

• You are missing the import android.content.Context, or

• Your project is messed up, and the compiler cannot find android.content.Context in your build path

Solution 2

In case anyone else had this issue: I had the same problem with some code that called a method from the Play Licensing library. I fixed it by using Project > Clean on Play Licensing project (as opposed to the project where the error was showing up).

Solution 3

First you should fix all other errors in your code than you should repeat Project -> Clean in Eclipse to see if the error was fixed.

I can see android.content.Context in the imports section, what should I do to fix(or test) case 2?

@jcw: That's difficult to answer. Whether you are building from Eclipse with ADT, or Ant, the android.jar for your build target should be automatically included.

Okay, well that looks sufficiently confusing. Fortunately this is a small project, so I will just copy all the classes into a new project and see if that solves the problem.

Well, that worked..... I have no clue as to why. Accepted your answer for pushing me in the right direction.
