Thank u For replying much appreciated

the code above i can choose images 1x1 and will work but if i change this value here to choose multiple in gallery images will all turn white and u can choose multiple but wont attach to email

thanks again for your help and reply's

[Peyton McGinnis]

Can you point out which section of the code you're referring to?

Also I'm confused as to what the application does. Can you briefly explain? And do you know if the code uses any special libraries?

[Sac]

yes bro so what this project does it u can choose images from android gallery multiple then it shows it in a imageview then you would press send and it will ask what email would u like to open with (i use gmail) it will take the images and text and add it to attachments in gmail automatically

libraries it uses yes
gallery adapter the code for that is here :

Sadly, I'm not really sure how to help here. If this is intended to be an Android app, I would take a look at the Android developer documentation here.

I wish I could assist further but I'm not very familiar with these APIs.

Stackoverflow? x)
