Android Build an Interactive Story App (Retired) Finishing the User Interface Loading the First Page

I get a java.lang.NullPointerException on mChoice2.setText(page.getChoice2().getText()); removing it makes it work

I get this error Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String com.example.android.interactivestory.model.Choice.getText()' on a null object reference at com.example.android.interactivestory.ui.StoryActivity.loadPage(StoryActivity.java:61) at com.example.android.interactivestory.ui.StoryActivity.onCreate(StoryActivity.java:49)

My GIT Repo is https://github.com/iandjx/InteractiveStory.


Further investigation showed that when page object is created with mStory.getpage(0) in line 52 of StoryActivity.java. The debugger shows that mChoice2 is null. This may be the one causing the NullPointerException but I dont see any problem with my code.

Ok I made a stupid mistake. Apparently line 14 in Page.java. I duplicated mChoice1 instead of mChoice 2. See diff in my commits :) Everything is now working.

I love the debugger!
