I am trying to learn fragments to modernize an app I originally wrote for android 1.5 that uses Date Picker Dialog. I am using the android-support-v4 library. When I run the code in Eclipse Juno 20120614-1722 it only shows android 4.0 emulators and there is a red X beside my Samsung phone running 2.3.5. When I push the package to phone, the code runs.

Here is the code

FragTestActivity.java

package xyz.marklasby.fragtest;

import java.text.SimpleDateFormat;
import java.util.Calendar;

import android.app.DatePickerDialog;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.support.v4.app.FragmentActivity;
import android.view.View;
import android.widget.Button;
import android.widget.DatePicker;

public class FragTestActivity extends FragmentActivity {

private Button date;
private Calendar now;
private SimpleDateFormat sdf = new SimpleDateFormat(" EEE MMM dd/yyyy");

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    date = (Button) findViewById(R.id.setdate);
    now = Calendar.getInstance();
    date.setText(sdf.format(now.getTime()));

    date.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
    editDate(v);
    }
});
}

public void editDate(View v) {
DialogFragment newFragment = DatePickerFragment.newInstance(new DatePickerDialog.OnDateSetListener() {
    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
    now.set(year, monthOfYear, dayOfMonth);
    date.setText(sdf.format(now.getTime()));
    }
});
newFragment.show(getSupportFragmentManager(), "datePicker");
}
}

DatePickerFragment.java

package xyz.marklasby.fragtest;

import java.util.Calendar;

import android.app.DatePickerDialog;
import android.app.Dialog;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;

public class DatePickerFragment extends DialogFragment {

static DatePickerDialog.OnDateSetListener mListener;

public static DatePickerFragment newInstance(DatePickerDialog.OnDateSetListener listener) {
mListener = listener;
return new DatePickerFragment();
}

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
return new DatePickerDialog(getActivity(), mListener, year, month, day);

}
}

Manifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="xyz.marklasby.fragtest"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk

<application

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>

What am I doing wrong?
