Using executor on android

Question

I’m trying to use an executor to record data in the database using threads. When instantiating an object from the Executor Service class and retrieving an instance from Executors.newSingleThreadExecutor(); returns the error that is not finding the newSingleThreadExecutor instance/declaration.

   ExecutorService exec = new Executors.newSingleThreadExecutor();

                       exec.execute(new Runnable() {
                            @Override
                            public void run() {

                                //Adicionando tarefa
                                addTask(itemList);

                            }
                        });

Answer 1

Don’t use the new.

Executors.newSingleThreadExecutor() is a method and not a class.

ExecutorService exec = Executors.newSingleThreadExecutor();

Its function is to create an instance of Executorservice which in this case uses a single worker thread.
