I’m trying to build an app with android using room as a database. While initializing the database I seem to have a problem using the databaseBuilder() method of room. I always get the error: can’t find symbol Room.databaseBuilder().
From my perspective it seems like the databaseBuilder doesn’t exist. I already tried to import androidx.room into my project but it still can’t find the method.
Is there a reason why it won’t find method databaseBuilder in class room or are there any alternatives?

This is my code:

import android.content.Context;

import androidx.room.Database;
import androidx.room.RoomDatabase;

@Database(entities = {Ente.class}, version = 1)
public abstract class DB extends RoomDatabase {

    public abstract dao Dao();

    private static DB _instance;

    public synchronized static DB getInstance(final Context context){
        if (_instance == null){
            synchronized (DB.class){
                if(_instance == null){
                    _instance = Room.databaseBuilder(context.getApplicationContext(),
                            DB.class,"Alle_Anzeigen");
                }
            }
        }
        return _instance;
    }

}
