public class MainActivity extends ActionBarActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

try {

readAllContacts();

} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}

public void readAllContacts() throws IOException {
String[] contacts = new String[] {
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER };

String name = null;
String phonenumber = null;

TextView txt = (TextView) findViewById(R.id.readcontact_results);
Cursor cursorphoneContacts = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, contacts,
null, null,
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " Asc");

try {

} catch (CursorIndexOutOfBoundsException o) {
System.out.println("Error" + o);

if (cursorphoneContacts != null && cursorphoneContacts.getCount() > 0) {
cursorphoneContacts.moveToFirst();
do {

name = cursorphoneContacts.getString(cursorphoneContacts
