How to add EditText to the image in Gallery and also camera activity in android.

Today i will tell about a program which initiate camera to capure an image.
The aim of this program is stated as:



1.Start camera for taking photo.
2.Show all images in a custom gallery.
3.Give appropriate caption for each photo.
4.Click on photo to view in large and can delete it.
5.View the name and caption of all photoes you captured in a dynamic way( TextView created    dynamically).

How to call json webservice android

Today i am going to show you how to call a webservice in android which returns data in a json format.This data will be displayed in a listview using fragment.


1.MainActivity.java

package com.example.parsejson;
import android.app.Activity;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.content.res.Configuration;
import android.os.Bundle; 
public class MainActivity extends  Activity {
  @Override
  protected void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     Configuration config = getResources().getConfiguration();
     FragmentManager fragmentManager = getFragmentManager();
     FragmentTransaction fragmentTransaction = 
     fragmentManager.beginTransaction();

     Myfragment pm_fragment = new Myfragment();
        fragmentTransaction.replace(android.R.id.content, pm_fragment);
     fragmentTransaction.commit();
  }
  
   

}
