[android-developers] Issue with startActivity
I am trying to start a activity from ListActivity but its crashing.
package net.apachetechnology.Organizer;
import android.R;
import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class Organizer extends ListActivity {
private ArrayAdapterItem m_adapterItems;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Item[] items = {
new Item(Task.class, Add Task),
new Item(test.class, Testing),
};
m_adapterItems = new ArrayAdapterItem(this,
R.layout.simple_list_item_1, items);
setListAdapter(m_adapterItems);
}
@Override
protected void onListItemClick(ListView l, View v, int position,
long id) {
//startActivity(m_adapterItems.getItem(position));
//m_adapterItems.getClass();
Intent intent = new Intent();
intent.setClass(Organizer.this, test.class);
startActivity(intent);
}
class Item extends Intent {
String s;
public Item(Class? c, String s) {
super(Organizer.this, c);
this.s = s;
}
@Override
public String toString() {
return s;
}
}
}

Re: [android-developers] Issue with startActivity
Did you add the new activity (test) to the manifest?
What's in logcat?
BTW, you don't need to do your own try/catch blocks with error logging
just to see what's going on. Just use logcat.

Re: [android-developers] Issue with startActivity
You need to add the test activity into your manifest.
Anyway, use logcat to see the error that is being thrown, as Kostya
suggested.
