I'm new to all this. So I'm trying to learn and I have the code correct in my eclipse IDE, but everytime I run the the app on the emulator it force closes without doing a thing. I checked my code again and i get these screens saying: "The JAR of this class file belongs to container 'Android 2.0' which does not allow modifications to source attachments on its entries. " Then it shows this:
// Compiled from View.java (version 1.5 : 49.0, no super bit)
public abstract static interface android.view.View$OnKeyListener {

// Method descriptor #4 (Landroid/view/View;ILandroid/view/KeyEvent;)Z
public abstract boolean onKey(android.view.View arg0, int arg1, android.view.KeyEvent arg2);

Inner classes:
[inner class info: #1 android/view/View$OnKeyListener, outer class info: #7 android/view/View
inner name: #9 OnKeyListener, accessflags: 1545 public abstract static]
}
Is this causing my problem? Any help would be nice.
Thanks

In the console view of eclipse i get this message when trying to run or debug my todo list app:

[2010-06-05 00:04:06 - Todo List] WARNING: Application does not specify an API level requirement!
[2010-06-05 00:04:06 - Todo List] Device API version is 5 (Android 2.0)

Maybe this can help whoever is looking at my problem.

Thanks again.

Just starting myself, but see if this helps.......

When you set up your project did you set it to api level 5?

In your AndroidManifest.xml, is the minimum SDK entered,

<uses-sdk android:minSdkVersion="5" />

If nothing else you can try, Project -> Clean and then rerun the project to see if it works.
