If that's your whole main.xml, then a few things are missing, notably,
there is no button with id=helpbutt, or any other buttons implied by
"another similar button" comment in the code. You are probably getting a
NullPointerException when calling "help.setOnClickListener".
Post logcat output here, including the part under "Caused by" so this
can be verified.
And you should have a portrait layout, too (either in layout-port or
just layout) so you can handle orientation changes.

application while it is already in landscape it stops unexpectedly and
displays a window ActivityThread.performLaunchActivity(ActivityThread
$ActivityRecord, Intent) line: 2496 saying source not found.
The same xml works fine in a Hello Android project that this one is
based on and I can't see any relevant differences in settings or
AndroidManifest.xml between the two projects. ScrollView does seem to
be the problem as it works fine if I remove it.
Grateful for any ideas on this.
main.xml in layout-land:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/
android"
android:id="@+id/scrollview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<TextView
android:id="@+id/textview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</ScrollView>
.java
public class InvertsUK extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button help = (Button) findViewById(R.id.helpbutt);
help.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent myIntent = new Intent(view.getContext(),
ViewHelp.class);
startActivityForResult(myIntent, 0);
}
});
...another similar button
}
}
