whats the error message in my logcat

Question

I have got this logcat error more then one time. This time I started a new Activity from a non-Activity subclass. The new Activity that starts is empty, so it has nothing with the content to do.

Here are the logcat lines:

post your code how your are starting an activity from your class. — Padma Kumar, Jan 14 '12 at 11:23
Maggie: Yes I have. Padma: Easy like this: context.startActivity(new Intent("android.intent.action.SETTINGS")); — SlowDeepCoder, Jan 14 '12 at 12:55
could you post some more of the code? The error basically means you're trying to say something is one class, when it's not. Specifically, if you do anything with the Activity you're starting — Alex Curran, Jan 14 '12 at 17:33

 Caused by: java.lang.ClassCastException: com.JDL.Apps.Snake.SettingsScreen 01-14 11:11:03.702: ERROR/AndroidRuntime(299):  at android.app.Instrumentation.newActivity(Instrumentation.java:1021)

In short you have a class cast exception.

it means that you don't have compatible objects to cast or passing a wrong type of object as a parameter there which is most likely. We need to see that Instrumentation.java line 1021 – Sergey Benner Jan 14 '12 at 12:58
you need to provide the code as i wrote it in my previous comment mate. – Sergey Benner Jan 14 '12 at 18:42
