It shows an error in a ImageView of my main class activity, but all the details are been correct in my coding side.

What's this error, how to over come this?

You seem to use the deprecated AbsoluteLayout? Can you post the code that is causing this error. — RoflcoptrException

ClassCastException in FirstImage class on line 106 ? It seems you try to cast something as an AbsoluteLayout in onCreate() method where it is not.

I was getting this error Caused by: java.lang.ClassCastException: android.widget.LinearLayout cannot be cast to android.widget.TextView:

I changed

stringsAdapter = new ArrayAdapter<String>(this,R.layout.main,myStrings);

To

stringsAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_expandable_list_item_1,myStrings);**

and problem is solved for me.
