I am a student of computer science and am new to Android programming. I am trying to create an application that allows images to be edited, then placed in folders to be viewed as a sort of slide, or share the finished images to social-media websites.
I currently have a code that i am experiencing some trouble with, concerning switching between activities by pressing a button. Whenever i run the application on my phone, it works fine until i press the button to go to my "send email" activity which causes it to force close. The second activity which sends an email works fine when i run it by itself. But the problem is linking it to my main activity.
I have tried using codes i found on the internet for switching to a new activity, but it doesn't seem to work. I know this is supposed to be a simple fix, but i just can't seem to find exactly where i'm going wrong.
Below is the source code that i used and edited:
AndroidManifest.xml (includes code for Aviary SDK)
The second activity is the send_mail activity at the very bottom of the code.

Expected result: Pressing the button from the main page will open the activity for sending email.
Any help would be highly appreciated. Hoping for favorable responses from the community. Thank you for taking to time to read my post.
