Application stops with message like "Unfortunately Soduku has Stopped" - android
I am totally new to Android . I am using the book Hello, Android. I have created a button for "about" that displays information about the sudoku game. But as soon as i click it, the application stops saying "Unfortunately sudoku has stopped".

In about.xml Change scrollview to ScrollView and TextView
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dip" >
<TextView
android:id="#+id/about_content"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/about_text" />
</ScrollView>
Is the buttons's onclick attribute pointing to an existing method in the activity class?
If you have
android:onClick="somefunction"
in the XML layout,
then you must have:
public void somefunction(View view) {
//do stuff
}
in the activity
Error seeems to be here in these statements : at org.example.sudoku.About.onCreate(About.java:9) 02-22
Line 9 of About.java code...most prob related to setContentView()
Check your xml code that you are setting on, seems to be bug there...
Good option while debuging would be to go step by step, like say removing all your xml code here with single textview layout to see if there is problem or not... and so on....
