Attribute must be constant in Retrofit @Header

I want to pass a header to each POST request in a retrofit api . Since i have lots of methods hear, i can't copy/paste the header information for every method.

public interface ApiInterface {
    String[] header = {"Accept:application/json",
                       "apiKey:12345",
                       "Content-Type:application/json"};

    @Headers(header)
    @POST("signup?")
    Call<SignupResponse> createUser(@Body SignupData signupData);

    @Headers(header)
    @POST("another")
    ....
}

The header variable in @HEADER creates this error:

Attribute must be constant

How can i solve the problem?

Use:

@Headers({"Accept:application/json",
         "apiKey:12345",
         "Content-Type:application/json"})
@POST("another")

See the "Header Manipulation" section of the Retrofit documentation.

Try this 

@Headers({"Accept:application/json",
            "apiKey:12345",
            "Content-Type:application/json"})
@POST("signup?")
    Call<SignupResponse> createUser(@Body SignupData signupData);
