Android Room - Get the id of new inserted row with auto-generate

Question

This is how I am inserting data into database using Room Persistence Library:

Entity:

@Entity
class User {
    @PrimaryKey(autoGenerate = true)
    p         


        

Answer 1

Get the row ID by the following sniplet. It uses callable on an ExecutorService with Future.

 private UserDao userDao;
 private ExecutorService executorService;

 public long insertUploadStatus(User user) {
    Callable insertCallable = () -> userDao.insert(user);
    long rowId = 0;

    Future future = executorService.submit(insertCallable);
     try {
         rowId = future.get();
    } catch (InterruptedException e1) {
        e1.printStackTrace();
    } catch (ExecutionException e) {
        e.printStackTrace();
    }
    return rowId;
 }
