Hello i asked the same question few days ago on StackOverflow but no answer...and i kinda  need an answer

The problem is that Glide .listener() is triggered image by image, so when i tried to set my fragment layout invisible until all images are loaded, it set's fragment layout visibility to visible after first image is loaded and  ignores the fact that rest of images are still not loaded into imageview.
Glide checks with it's listener images by images and after first one is ready it set's my visibility t visible and i do not want this..i want to my fragment layout be invisible until all images are ready to display. Now i will basically past my SstockOverflow post here.

i have a fragment with several recycleviews that contain some text and image from users. Problem is that my images are loaded a second or less after my layout is inflated. I can't use any placeholder for that time or something else.
My instructions are that my layout must be shown only when all data and images are ready from all recyclerviews, and be shown in the same time. I am using glide .listener() method.
I tried: 1)to set boolean value in .listener() and save it in SharedPref and load it in my fragment where my recycleviews are and if Boolean value is the same then set visibility of fragment to visible ,which previously was set to invisible
2) to do the same thing just with custom callbacks
3)and this solution that i am going to past here. Basically i am passing my layout to adapter with constructor and setting it invisible in .listener().

 won't update to server

What server are you talking about?  What protocol are you using to send the String to the server?

Why do you have to use the debugger to see the error message?  Can the code receive/extract the message and print it on the logcat?

I am using retrofit and okhttp...and sung a HashMap to send all data to the server..  but what is weird is that i got some base64

but getting that error

What happens when you execute the app?

Simply won't update to server. If i go to debug then i see 400 bad request and in error body i got that error, but my app doesn't crash simply wont do what is supposed to do..

What variable on line 32 has the null value?  Backtrack in the code to see why that variable is null.

that is line 17 here in post

it seems that is problem.Because it gives me a warning that is not assigned...and i don't know how to do it

I know what is this exception is and I know that there are a lot of similiar questions. But I can't apply those solutions to my problem. Everything works fine when I am using findById() but when I am trying to use data binding I got stuck. I am new in data binding.

and i am calling this class in my fragment:

my xml tv_content

There is no more data in the stream so the InputStream used on line 28 returns the -1.
Try using the InuputStreamReader for all the reads, not the InputStream.

I used BufferedReader and now it works were right problem was in in InputStream... hahahah what a sleepless night

in line 24
In my line 24 it shows number 123

but in line 28 it shows -1 ???

so in my while loop shows that podaci(data) are -1 and stop printing in log...but why??

EDIT: When i put this code :

my second log,in else, is activated like it's failed.
