  13. private Cursor getAllItems() {
    return sqld.query(Contract.Entry.TABLE_NAME,
    Contract.Entry.COLUMN_TIMESTAMP + "DESC"

    return sqld.query(Contract.Entry.TABLE_NAME, <<where the error occured

    Do you have any tutorial for the search button that will show all connected subjects to my ingredients list? I'm planning to put a search button for easy reference of the end-user. Example if i put 1 ham and 1 egg in my ingredients list (just like you do in your tutorial) then i will click the search button and everything will show should be connected to my ingredients list. Is there a way to do that? hoping for your response. This video taught me a lot. Thanks :))

    Thanks Brother you're helping me to learn new techniques in Android Development. I'll meet you at least once, if I come to Germany next year.

    Excellent guides, really like how clear and concise you are, nice pacing too.

  21. Just watched the first video, and wanna say that this is very interesting and informative, learned lots of staff, thanks) Now it is time to watch the next video) for sure, LIKE)

    Excellent tutorial! I have many years programming for android and you have already showed me a few new tricks in just this first video. Thank you!

  23. Just spend a couple hours watching a course on udacity about SQLite … those really help to digest the documentation 😉 / wrap my head around the concept… I feel rdy to follow this excersise here now ;). 4am here xD .. will continue after sleep xD

    I cant wait to finally load data from a database 😀 …

    ps : do you have a playlist link for android developers podcast ? I didnt find one for the latest stuff .Greetings Medy

  24. Here is an ideo for a video (series): maybe you should do more theretic videos. You show here how to use SQLite but I dont really unterstand what it is, what I can do with it in the first place. A comparison to Firebase would be great too. I cant find such tutorials as well and I think you would do a great job on creating these videos!

  25. Hello, I followed all three tutorials and they are great and I have implemented this into my own app! Thank you for the great tutorials!

    One tip – for complete beginners it helps if you add small comments to your code just so we have a better understanding of what some of the code is doing 🙂

    i subscribed too, thanks!
