Hi everybody!
I'm trying to enable the social share feature for my app.
I need to share an image and some text on Whatsapp, Facebook, Email, etc.
I tried the code of this post:
https://www.b4x.com/android/forum/t...elp-with-inline-objc.52849/page-6#post-336177
but it only works when I choose an online file. If I try to send a local file, it raises an error i can not debug (I have no idea about ObjectiveC, sorry)
Application_Start
Application_Active
Error occurred on line: 112 (modShare)

Can anyone help me to enable this feature?
Thank you so much.

Sorry, but I uninstalled and installed this with no changes it still crashing when I choose local file...
I've tried on Debug and Release Mode and both crash...
As i said, with online file it works perfectly.
If you look on the Error Log of my first post... it raises inside the objective C code... but I have no idea about objective C.

Thank you.

Hi.
Yes, I'm testing on real device...
I was adding logs to the inline code and it crashes here:
B4X:
NSLog(@"Here works");
UIActivityViewController *controller =
[[UIActivityViewController alloc]
initWithActivityItems:@[text, url, image]
applicationActivities:nil];
NSLog(@"Here crashes");
Log shows this:
Here works

For any reason, image is null...
i tried to load to an imageview and it loads...
maybe the inline code is wrong?

Here is the problem...
B4X:
image = [UIImage imageNamed:theimg];
I've changed it to:
B4X:
image = [UIImage imageWithContentsOfFile:theimg];
and worked...
For any reason, the method ImageNamed is not working with assets folder.
Thank you!!!
