How to save image through capturing in android to

We have tried this code for android and php. Please see below code.

Android

Scn.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                        // Open default camera
                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

                // start the image capture Intent
                startActivityForResult(intent, 100);
            }
 }
  protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
            if (requestCode == 100 && resultCode == RESULT_OK) {


                 selectedImage = intent.getData();
                    imageBitmap = (Bitmap) intent.getExtras().get("data");

                ByteArrayOutputStream baos = new ByteArrayOutputStream();
                imageBitmap.compress(Bitmap.CompressFormat.JPEG, 40, baos);

                imageView1.setImageBitmap(imageBitmap);

                byte[] imageBytes = baos.toByteArray();
                String encodedImage = Base64.encodeToString(imageBytes, Base64.DEFAULT);

                    port, autoClose);
        }

        @Override
        public Socket createSocket() throws IOException {
            return sslContext.getSocketFactory().createSocket();
        }
}

It returns parsing bytestring. Its value is too much long.

PHP

 $base=$Data['images'];
 $binary=base64_decode($base);
 header('Content-Type: bitmaps; charset=utf-8');
 header("Content-Length: " . mb_strlen($base, '8bit'));
 $file = fopen('qr_code.jpeg', 'wb');
 fwrite($file, $binary);
 fclose($file);
 echo 'Image upload complete!!, Please check your php file directory';

Above code is working. But it have some issue. Image save successfully in folder but image will be displayed as corrupted. How can we resolve this issue.

Thanks in advance.

Please try this code this code working for me.

<?php

// Path to move uploaded files
$target_path = "uploads/";

// array for final json respone
$response = array();

// getting server ip address
$server_ip = gethostbyname(gethostname());

// final file url that is being uploaded
$file_upload_url = 'http://' . $server_ip . '/' . '/xyz/' . '/' . $target_path;


if (isset($_FILES['image']['name'])) {
    $target_path = $target_path . basename($_FILES['image']['name']);

    // reading other post parameters
    $email = isset($_POST['email']) ? $_POST['email'] : '';
    $website = isset($_POST['website']) ? $_POST['website'] : '';

    $response['file_name'] = basename($_FILES['image']['name']);
    $response['email'] = $email;
    $response['website'] = $website;

    try {
        // Throws exception incase file is not being moved
        if (!move_uploaded_file($_FILES['image']['tmp_name'], $target_path)) {
            // make error flag true
            $response['error'] = true;
            $response['message'] = 'Could not move the file!';
        }

        // File successfully uploaded
        $response['message'] = 'File uploaded successfully!';
        $response['error'] = false;
        $response['file_path'] = $file_upload_url . basename($_FILES['image']['name']);
    } catch (Exception $e) {
        // Exception occurred. Make error flag true
        $response['error'] = true;
        $response['message'] = $e->getMessage();
    }
} else {
    // File parameter is missing
    $response['error'] = true;
    $response['message'] = 'Not received any file!F';
}

// Echo final json response to client
echo json_encode($response);
?>

I'm not and Android developer.

But I know the problem is with your request. You are passing all data in GET request method (appending parameters in URL). But It has limitation of 2,083 character length. (It depends on webserver actually)

So, If your image size is higher than that, it will simply truncate from URL.

For the solution, you have to use POST request to submit data to webservice.

Android

Refer answer of this question for android code snippet

PHP code

<?php

$json=json_decode($_POST['json']); //decoding json which is received from Android.

$photo=$json->images; //get image data (which is encoded in base64)

/* Decoding image */
$binary = base64_decode ( $photo );

/* Opening image */
$file = fopen ( 'file_name_to_create.jpeg', 'wb' );

/* Writing to server */
fwrite ( $file, $binary );

/* Closing image file */
fclose ( $file );

?>

It will create file_name_to_create.jpeg in current directory.

POST request using Android

Hi i have used this approach to save myImage.

Create images folder inside your root.

$allowedExts = array("gif", "jpeg", "jpg", "png");

$temp = explode(".", $_FILES["file"]["name"]);

$extension = end($temp);

move_uploaded_file($_FILES["file"]["tmp_name"], "../images/" . $varFileName);
Use this URL to download my code for sending imagefile to php server.
