Hello Droid Friends,
Today , I am sharing the code for capture Image from Camera and Gallery . Actually
I found different behavior of Camera capture Intent and Gallery Intent on different
Android devices .
Here are the few issue I found while capturing Image from Camera and Gallery:
1. In some devices like Samsung the Camera capture Intent returns
data null or some time gallery Intent returns data null.
2. Android Camera : data intent returns null
3. Android camera capture activity returns null Uri
4. onActivityResult Camera resulting data as null (SAMSUNG)
I too faces all these issue, then I uses below code which works dine for me.
Code:.
1. MainActivity.java:
2. ImageUtils.java
Download code : Camera and Gallery Demo
Hope this will help some one.
Enjoy Coding.... :)
