[android-developers] First app not working

2016-01-09 Thread Ricardo Morales 
So I tried doing the first app tutorial from the web, the one that sends 
text to one activity to another.
But I think i really suck at this.

Here is my logcat:

I don't think you suck at this, I think you need to have a bit more
patience and remember that there is a learning curve here.  First thing you
need to learn is probably how to read a stack trace like the one that
appears at the bottom of your logcat.  In this case it is telling you that
you have a null pointer in your MyActivity.OnCreate at line 25 so look at
that line of code and figure out why that is!
