This is a good idea, however there are several mistakes in the content (I only watched the beginning):

1. The product name is B4A. Basic4android was the name until 2012.
2. HttpUtils2 shouldn't be used. It was replaced with OkHttpUtils2 many years ago.
3. There is no reason to use Glide or Picasso to download an image.
4. You shouldn't have a JobDone sub.
Complete code to download an image:

B4X:

Sub DownloadImage(Link As String, iv As ImageView)
   Dim j As HttpJob
   j.Initialize("", Me)
   j.Download(Link)
   Wait For (j) JobDone(j As HttpJob)
   If j.Success Then
     iv.Bitmap = j.GetBitmap
   End If
   j.Release
End Sub

this tutorial is supposed to be an introduction to glide library and I will make other tutorials for glide and retrofit

I would greatly advise that you then change the title of your thread as I was confused until I read the line above.. Erel has a b4x video tutorials in https://www.b4x.com/etp.html for beginners.

First post update: how to connect b4a to NOX player

I think if you copy adb.exe from Android SDK folder to NOX player folder, then it will recognize B4A bridge.

Yes that is somewhat true but as far as I know, you have to copy adb.exe from NOX player to SDK folder...(not from SDK folder to NOX folder)
I will explain it in the description of the Video

Hello @ADeveloper,
The video above is nicely produced, with nice clear pronunciations of your words and also no background noise

In your YouTube tutorial video titles, maybe you could include the words Android as well as B4A or iOs as well as B4i etc etc etc, and also in your YouTube tags. Actually talking YouTube tag, you should include 'yt:cc=on' as one of your tags

You appear to have the knack for making educational YouTube videos, so how about making a follow-up video but based on the XUI B4XDrawer which can be found in the link in below.

Edit: Cross platform example based on B4XPages https://www.b4x.com/android/forum/threads/b4x-b4xpages-b4xdrawer.120246/ A class that implements a sliding menu. Unlike the nice jfeinstein SlidingMenu library the drawer covers the activity instead of pushing it. It is similar to the various...

Keep up with making your tutorial videos, the production quality is good. Also your videos will help newer B4X developers to get to grips with developing apps using the B4X suite of development tools. Your videos also helps to promote B4X so that's a good thing too ???

SQLite Database for beginners - part 2

ADeveloper · Jul 25, 2020

SQLite database + xCLV ( plz watch my other tutorials about clv before this one):

now we try to search for a record in the table:

what do you suggest for other tutorails? xui view? sqlite? json + b4a? b4j? .....

embedded · Jul 26, 2020

Keep it up.It helps me lot.God bless you.

My suggestion,

Create a B4J Desktop app. It is much easier than B4A.
Then use most of the same code, share the codes, and make an Android app quickly.

Yes, there are some examples for same in the Forum, but members we benefit with another simpler explanation and helpful guide.

Thanks for your effort in expanding B4X

Regards,

Anand

xui view please

Peter Simpson · Jul 28, 2020

Excellent stuff @ADeveloper,
I'm more than sure that these tutorial videos will help more developers to find and create apps using the B4X suite of RAD tools. Your titles etc on YouTube are a lot better but you should also add the word 'Android' in the titles, I would

Anyway hopefully your hard work making these great tutorial videos will help potentially new developers to find this great forum and its great resources...
