I'm doing a project where you click an image then launches the second activity that contains the image, title and description (it changes depending on the image). I have already set the onClickListener but it doesn't work. The project is working fine and I'm not getting an error as I run it but when I'm in the actual project itself, whenever I click the image the app suddenly closes without giving error message. Any idea how to solve this? Thanks
