Hello,
i've created a new android project target 8, with default activity
I've assigned an id to textview with text "Hello world".
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:id="@+id/tvProva"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/>
</LinearLayout>
This is the unique activity
package it.prova;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class EmptyActivity extends Activity
{
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView tv = (TextView) findViewById(R.id.tvProva);
tv.setText("Prova ");
}
}
And this is logcat
02-24 16:09:25.374: ERROR/AndroidRuntime(537): Caused by:
java.lang.NullPointerException

I'm using sdk r11 and adt v10.
I think there is a problem with resources.
Any idea?
Thanks.
