hello there , my app is crashing 💥 and returning null path error in piccasso while i am sending text to server, hence i protect every code with "*IfNotNull(
if(x != null)
)*" i spend over 1 n half week stucked trying to solve this problem 😭 please please help me
theerror.kt
z
Can you post the exception with the stacktrace?
m
Is it this?
Copy code
if (uri == null) return
val filename = UUID.randomUUID().toString()
val rf = FirebaseStorage.getInstance().getReference("images/$filename")

Rf.putFile(uri!!)
The 
uri
could be mutated and set to null before 
RS.putFile(uri!!)
. Doing 
!!
is kind of asking for null pointers here 😛
I see you are doing 
!!
multiple other places as well.

the path must not be empty
@marstran but i am able to send the picture . the error is while i am sending the text
z
If you could post a stack trace that would help show what is going on when the error occurs (it's the bunch of lines of class names with line numbers).

@Zach Klippenstein (he/him) [MOD] sorry for delay

Ok, so your stacktrace says that you are sending in a 
null
to Picasso on this line: 
.load(fileUri?.imageUri)
. So either 
fileUri
is null or 
imageUrl
is null.
I think this line is the culprit: 
fileUri?.imageUri != null || fileUri?.imageUri != ""
. Should it be 
&&
instead of 
||
?
a
I know when I send text the image URL returns null so to get rid of that I put picasso in If image uri not null As I do it in my code
m
Yes, but your if-test is wrong. See my previous message.
a
Ok I am going to try
@marstran ohh my god , ohh my God, oh my God, oh My God Ohh ohh ohh 🤑🤑🤑🤑🤑🤑🤑🤑🤑🤑🤑🤑🤑🤑🤑 it works, I haven't think this little code can affect all my project thank you very much very very much!!!!
