Re: [android-developers] Your content must have a ListView whose id attribute is 'android.R.id.list'

Pramod,

Looks like you are using ListActivity, which expects that the list view
has a certain predefined ID.

That id is defined inside Android, and is the "android.R.id.list"
mentioned in the logcat.

Either change the layout to use"@id/android:list" (and also change the
parameter to findViewById), or change your activity to subclass from
Activity, not ListActivity.

I would recommend the latter, since your code doesn't really leverage
ListActivity.
