Android Preferences for Images

I want to design a simple settings page for an android application. It provides to change username, password, e-mail and profile picture of registered user. I did all parts except profile picture. I created a preference screen and used EditTextPreference for username, password and e-mail. However, I couldn't find a proper preference tag for images.

Are there any suggestions?

This is the xml part;

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://ift.tt/nIICcg" >
 <PreferenceCategory
   android:summary="Username and password information"
   android:title="Login information" >
  <EditTextPreference
     android:key="username"
     android:summary="Please enter your login username"
     android:title="Username" />
  <EditTextPreference
     android:key="password"
     android:summary="Enter your password"
     android:title="Password" />
  <EditTextPreference
     android:key="e-mail"
     android:summary="Please enter your e-mail address"
     android:title="E-mail" />
  <Preference
     android:key = "image"
     android:summary = "Please upload an image"
     android:title = "Profile Picture" />
 </PreferenceCategory>
</PreferenceScreen>

This is the code;

package com.example.preferencedemotest;

import android.support.v7.app.ActionBarActivity;
import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.preference.Preference;
import android.preference.PreferenceManager;
import android.provider.MediaStore;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class PreferenceDemoActivity extends Activity {
TextView textView;

@Override
public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.activity_preference_demo);

   Button btnPrefs = (Button) findViewById(R.id.btnPrefs);
   Button btnGetPrefs = (Button) findViewById(R.id.btnGetPreferences);

   textView = (TextView) findViewById(R.id.txtPrefs);

   View.OnClickListener listener = new View.OnClickListener() {

   @Override
   public void onClick(View v) {
   switch (v.getId()) {
   case R.id.btnPrefs:
      Intent intent = new Intent(PreferenceDemoActivity.this,
      PrefsActivity.class);
      startActivity(intent);
      break;

   case R.id.btnGetPreferences:
      displaySharedPreferences();
      break;

   default:
     break;
   }
   }
   };

   btnPrefs.setOnClickListener(listener);
   btnGetPrefs.setOnClickListener(listener);
}


private void displaySharedPreferences() {
   SharedPreferences prefs = PreferenceManager
    .getDefaultSharedPreferences(PreferenceDemoActivity.this);

   String username = prefs.getString("username", "Default NickName");
   String passw = prefs.getString("password", "Default Password");
   String email = prefs.getString("e-mail", "Default E-mail");
   boolean checkBox = prefs.getBoolean("checkBox", false);
   String listPrefs = prefs.getString("listpref", "Default list prefs");

   StringBuilder builder = new StringBuilder();
   builder.append("Username: " + username + "\n");
   builder.append("Password: " + passw + "\n");
   builder.append("E-Mail: " + email + "\n");
   builder.append("Keep me logged in: " + String.valueOf(checkBox) + "\n");
   builder.append("List preference: " + listPrefs);

   textView.setText(builder.toString());
}
}
