Android Question error: cannot find symbol

[Arthur Ávila]

I had a project that was working as intended. Suddenly I can't compile it anymore and got this error

Compiling debugger engine code.    (1.80s)
Compiling generated Java code.    Error
javac 1.8.0_191
src\consulta\veiculos\restricoes\fipe\main.java:521: error: cannot find symbol

                                        ^

If I remove the class placamod I get

javac 1.8.0_191
src\consulta\veiculos\restricoes\fipe\main.java:538: error: cannot find symbol
public consulta.veiculos.restricoes.fipe.starter _starter = null;

I can't figure what is the issue. Any ideas?

I guess I found the problem, it was a duplicated java code

#if Java
public static class MyAdListener extends com.google.android.gms.ads.AdListener {
