Android Upload Image to Php Server

Today I will write a code for upload image to php server in android in string .You need to decode string file in php server using Base64 .

Step 1: Create Project  UploadImageToServer .

Step 2 : Write Code in MainActivity 

package com.ritesh.uploadimage;

import java.io.ByteArrayOutputStream;

import org.json.JSONObject;

import android.net.Uri;
import android.os.AsyncTask;
import android.os.Bundle;
import android.provider.MediaStore;
import android.app.Activity;
import android.app.ProgressDialog;
import android.content.Intent;
import android.database.Cursor;
import android.graphics.Bitmap;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.Toast;

public class MainActivity extends Activity {
public static final int RESULT_LOAD_IMAGE = 10;
private static final int CAMERA_REQUEST = 1888;
String imagestring="";
Bitmap photo;
ImageView setimage;
Utils utils;
String message;
ProgressDialog pDialog;

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

Button ButtonCamera=(Button)findViewById(R.id.buttonCamera);
Button buttonGallery=(Button)findViewById(R.id.buttongallery);

Button ButtonUpload=(Button)findViewById(R.id.buttonupload);
setimage=(ImageView)findViewById(R.id.image);
ButtonCamera.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
//Capture image from camera
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

startActivityForResult(intent, CAMERA_REQUEST);
}
});
buttonGallery.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
//Capture image from gallery
Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

startActivityForResult(i, RESULT_LOAD_IMAGE);
}
});
ButtonUpload.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
utils=new Utils();
new UploadImage().execute();
}
});
}





@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);

if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {

Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };

Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();

int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();


   photo=Utils.decodeSampledBitmapFromPath(picturePath, 400, 400);

loadImage();

 } else  if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK)  {

 photo = (Bitmap) data.getExtras().get("data");


loadImage();




}}


       private void loadImage() {
     // TODO Auto-generated method stub
 
      Log.e("addimg", "imgggg");
      //resize image according to your need and replace value of 200 and 200
      Bitmap btm00 = Utils.getResizedBitmap(photo, 200, 200);
      setimage.setImageBitmap(btm00);
       
          ByteArrayOutputStream bao = new ByteArrayOutputStream();
       
          photo.compress(Bitmap.CompressFormat.JPEG, 90, bao);
          byte[] ba = bao.toByteArray();
          imagestring = Base64.encodeBytes(ba);
 }
       class UploadImage extends AsyncTask<String, String, String>{
       
      @Override
   protected void onPreExecute() {
    // TODO Auto-generated method stub
    super.onPreExecute();
    ProgressDialog pDialog=new ProgressDialog(MainActivity.this);
    pDialog.setMessage("Sending..");
    pDialog.setCancelable(true);
    pDialog.show();
   
   
   }

      @Override
protected String doInBackground(String... arg0) {
// TODO Auto-generated method stub
try {
JSONObject json=utils.SendToServer(imagestring);
message=json.getString("MSG");
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}


return null;
   }
@Override
protected void onPostExecute(String result) {
// TODO Auto-generated method stub

pDialog.dismiss();
Toast.makeText(MainActivity.this, "Hello :"+message, Toast.LENGTH_LONG).show();
}
               }
       
}

Step 3: Write this code in JSONParser

package com.ritesh.uploadimage;

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStream;

import java.io.InputStreamReader;

import java.io.UnsupportedEncodingException;

import java.util.List;

import org.apache.http.HttpEntity;

import org.apache.http.HttpResponse;

import org.apache.http.NameValuePair;

import org.apache.http.client.ClientProtocolException;

import org.apache.http.client.entity.UrlEncodedFormEntity;

import org.apache.http.client.methods.HttpPost;

import org.apache.http.impl.client.DefaultHttpClient;

import org.json.JSONException;

import org.json.JSONObject;

import android.util.Log;

public class JSONParser {

private InputStream is = null;

    private JSONObject jObj = null;

    private String json = "";

 

    // constructor

    public JSONParser() {

 

    }

    

    public JSONObject getJSONFromUrl(String url, List<NameValuePair> params) {

    // Making HTTP request

    try {

    // defaultHttpClient

    DefaultHttpClient httpClient = new DefaultHttpClient();

    HttpPost httpPost = new HttpPost(url);

    httpPost.setEntity(new UrlEncodedFormEntity(params,"UTF-8"));

    HttpResponse httpResponse = httpClient.execute(httpPost);

    HttpEntity httpEntity = httpResponse.getEntity();

    is = httpEntity.getContent();

    } catch (UnsupportedEncodingException e) {

    e.printStackTrace();

    } catch (ClientProtocolException e) {

    e.printStackTrace();

    } catch (IOException e) {

    e.printStackTrace();

    }

    try {

    BufferedReader reader = new BufferedReader(new InputStreamReader(

    is, "utf-8"), 8);

    StringBuilder sb = new StringBuilder();

    String line = null;

    while ((line = reader.readLine()) != null) {

    sb.append(line + "\n");

    }

    is.close();

    json = sb.toString();

    Log.e("JSON", json);

    } catch (Exception e) {

    Log.e("Buffer Error", "Error converting result " + e.toString());

    }

    // try parse the string to a JSON object

    try {

    jObj = new JSONObject(json);

    } catch (JSONException e) {

    Log.e("JSON Parser", "Error parsing data " + e.toString());

    }

    // return JSON String

    return jObj;

    }

    

    public JSONObject getJSONFromUrl(String url) throws IllegalStateException, IOException, JSONException {

 

// Making HTTP request

// defaultHttpClient

DefaultHttpClient httpClient = new DefaultHttpClient();

HttpPost httpPost = new HttpPost(url);

HttpResponse httpResponse = httpClient.execute(httpPost);

HttpEntity httpEntity = httpResponse.getEntity();

is = httpEntity.getContent();

BufferedReader reader = new BufferedReader(new InputStreamReader(is,

"utf-8"), 8);

StringBuilder sb = new StringBuilder();

String line = null;

while ((line = reader.readLine()) != null) {

sb.append(line + "\n");

}

is.close();

json = sb.toString();

// try parse the string to a JSON object

jObj = new JSONObject(json);

// return JSON String

return jObj;

 

    }

}

Step 4: Write this Code in Utils

package com.ritesh.uploadimage;

import java.util.ArrayList;

import java.util.List;

import org.apache.http.NameValuePair;

import org.apache.http.message.BasicNameValuePair;

import org.json.JSONObject;

import android.graphics.Bitmap;

import android.graphics.BitmapFactory;

import android.graphics.Matrix;

public class Utils {

public static Bitmap decodeSampledBitmapFromPath(String pathName, int reqWidth, int reqHeight) {

   // First decode with inJustDecodeBounds=true to check dimensions

   final BitmapFactory.Options options = new BitmapFactory.Options();

   options.inJustDecodeBounds = true;

   BitmapFactory.decodeFile(pathName, options);

   // Calculate inSampleSize

   options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);

   // Decode bitmap with inSampleSize set

   options.inJustDecodeBounds = false;

   return BitmapFactory.decodeFile(pathName, options);

}

public static int calculateInSampleSize(BitmapFactory.Options options, int reqWidth, int reqHeight) {

   // Raw height and width of image

   final int height = options.outHeight;

   final int width = options.outWidth;

   int inSampleSize = 1;

   if (height > reqHeight || width > reqWidth) {

       if (width > height) {

           inSampleSize = Math.round((float)height / (float)reqHeight);

       } else {

           inSampleSize = Math.round((float)width / (float)reqWidth);

       }

   }

   return inSampleSize;

}

public static Bitmap getResizedBitmap(Bitmap bm, int newHeight, int newWidth) {

int width = bm.getWidth();

int height = bm.getHeight();

float scaleWidth = ((float) newWidth) / width;

float scaleHeight = ((float) newHeight) / height;

Matrix matrix = new Matrix();

// RESIZE THE BIT MAP

matrix.postScale(scaleWidth, scaleHeight);

// RECREATE THE NEW BITMAP

Bitmap resizedBitmap = Bitmap.createBitmap(bm, 0, 0, width, height,

matrix, false);

return resizedBitmap;

}

public JSONObject SendToServer(String imagestring) {

JSONParser jsonParser=new JSONParser();

// TODO Auto-generated method stub

List<NameValuePair> params = new ArrayList<NameValuePair>();

//Change your params (image)

 params.add(new BasicNameValuePair("image", imagestring));

//Change your server link and replace to this one (www.exampleupladurl.com)

 JSONObject json = jsonParser.getJSONFromUrl("www.exampleupladurl.com", params);

 return json;

}

}

Step 5: Write this Code in Manifest file 

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="com.ritesh.uploadimage"

    android:versionCode="1"

    android:versionName="1.0" >

    <uses-sdk

        android:minSdkVersion="8"

        android:targetSdkVersion="17" />

        <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

        <uses-permission android:name="android.permission.INTERNET"/>

    <application

        android:allowBackup="true"

        android:icon="@drawable/ic_launcher"

        android:label="@string/app_name"

        android:theme="@style/AppTheme" >

        <activity

            android:name="com.ritesh.uploadimage.MainActivity"

            android:label="@string/app_name" >

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

        </activity>

    </application>

</manifest>

Step 5: Downlaod Base64.java and insert in to your project  .
