Android Application Crashes on AVD and phone

Question

I am new at this (I mean brand spanking new). No this is not a homework assignment.

My app continues to crash on my phone and on the AVD. I am not sure what is going on. I followed this tutorial: https://www.youtube.com/watch?v=E8BVJWcEqHE .Can I get a little help please? This is a simple notepad style app which I am aiming for a 4.2 platform. I would post the LOGCAT but it is at 10,000 entries currently and is going to be more of an annoyance for you than anything else.

Thank you

`adb logcat -c` to clear your logcat entries file. I imagine all 10000 lines may not be due to your application alone. Try posting last 20 lines in any case. — PCoder, Apr 30 '14 at 21:49
Find the *error* in your logcat (red lines) and only post those. Chances are, you'll see what the problem is once you find it. — 323go, Apr 30 '14 at 21:55
Why would you do that `save.setOnClickListener(this);` ? remove it, and add in you XML file on your button code `android:onClick="saveAction"` and then add a method in your activity `public void saveAction (View view){ //Do whatever you want when the button is clicked } ` — , Apr 30 '14 at 22:36

Read your log, the error is on the method setupWidgets. If you want to work with fragments, the UI is created on fragment class PlaceholderFragment. Move all methods from activities into fragment class. See the code below.

In my case, the Access Rules Defined has been with the value "Forbidden". I removed it and made to None.

The error is gone and my app is working fine.
