Android CAMERA Application

Here, you can open camera using our app and take pictures and store in your SDCARD...

My Main.class  :

package com.example.cam;

import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.Toast;

public class MainActivity extends Activity implements OnClickListener {

 Button b;
 ImageView img;
 int requestcode=0;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        img=(ImageView)findViewById(R.id.img);
        b=(Button)findViewById(R.id.btn);
        b.setOnClickListener(this);
       
}
 @Override
 public void onClick(View v) {
  // TODO Auto-generated method stub
  Intent i=new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
  startActivityForResult(i, 0);
 }
 
 protected void onActivityResult(int requestcode,int resultcode,Intent data)
 {
  super.onActivityResult(requestcode, resultcode, data);
  if(requestcode==0)
  {
   Bitmap image=(Bitmap) data.getExtras().get("data");
   img.setImageBitmap(image);
   
  }
  else if(requestcode==RESULT_CANCELED)
  {
   Toast.makeText(getApplicationContext(), "Camera not working", 3000).show();
  }
   
 }
}

Here: 
Intent i=new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
  startActivityForResult(i, 0);
android.provider.MediaStore.ACTION_IMAGE_CAPTURE is a service in which the Camera action is located.Provider.MediaStore is used to set the Media location && Action_Image_Capture is to Take a Snap using camera.
Here is XML Code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity" >

    <Button
        android:id="@+id/btn"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="capture" />

    <ImageView
        android:id="@+id/img"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" />

</LinearLayout>
