Http Multipart requests are used to send heavy data data or files like audio and video to the server. Android Volley gives you a very faster and optimized environment to send heavy data or files to the server. Here I post a image file selected from the gallery.
How to capture image from camera?

Creating Server Side Scripts

The first thing we need is to create our server side web services. For server side I am using PHP and MySQL. And for this I am using Wamp server. You can still use xampp or any other application. Now follow the steps to create your web service to handle the file upload.

  •  Go to your server’s root directory (c:/wamp/www) and create a new folder. I created AndroidUploadImage.
  • Inside the folder create a folder named uploads, in this folder we will save all the uploaded images.
  • Create a file named upload.php and write the following code. 
    <?php
    // Path to move uploaded files
    $target_path = dirname(__FILE__).'/uploads/';
    if (isset($_FILES['image']['name'])) {
        $target_path = $target_path . basename($_FILES['image']['name']);
        try {
            // Throws exception incase file is not being moved
            if (!move_uploaded_file($_FILES['image']['tmp_name'], $target_path)) {
                // make error flag true
                echo json_encode(array('status'=>'fail', 'message'=>'could not move file'));
            }
            // File successfully uploaded
            echo json_encode(array('status'=>'success', 'message'=>'File Uploaded'));
        } catch (Exception $e) {
            // Exception occurred. Make error flag true
            echo json_encode(array('status'=>'fail', 'message'=>$e->getMessage()));
        }
    } else {
        // File parameter is missing
        echo json_encode(array('status'=>'fail', 'message'=>'Not received any file'));
    }
?>

Creating an Android Project

  1. Open Android Studio and create a new project (I created ImageUpload)
    How to create an android project ?
  2. Now add VolleyPlus to your project. You can quickly add it using gradle. Extract Gradle Scripts and open build.gradle (Module: app)
  3. Now inside dependencies block add the following line 
    compile 'dev.dworks.libs:volleyplus:+'
  4. So your dependencies block will look like 
    dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:24.0.0'
    compile 'dev.dworks.libs:volleyplus:+'
}
  5. Now click on Sync Project With Gradle Icon from the top menu
  6. And it will automatically download and add volley library to your project.
  7. Now we need to create the following layout.
    Volley Image Upload Layout
  8. For creating the above layout you can use the following xml code 
    <?xml version="1.0" encoding="utf-8"?>
<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:padding="16dp"
    tools:context="org.snowcorp.imageupload.MainActivity"
    android:orientation="vertical">
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="Upload Image using Volley"
        android:id="@+id/textView"
        android:layout_gravity="center_horizontal"
        android:layout_marginBottom="10dp"/>
    <Button
        android:id="@+id/button_choose"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@color/colorAccent"
        android:text="Browse Image"
        android:textColor="#fff"
        android:layout_gravity="center_horizontal"
        android:layout_margin="20dp"
        android:padding="10dp"/>
    <ImageView
        android:id="@+id/imageView"
        android:layout_width="200dp"
        android:layout_height="200dp"
        android:background="@drawable/border"
        android:layout_gravity="center_horizontal"
        android:padding="5dp"
        android:layout_margin="20dp"/>
    <Button
        android:id="@+id/button_upload"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@color/colorAccent"
        android:text="upload"
        android:textColor="#fff"
        android:layout_gravity="center_horizontal"
        android:layout_margin="20dp"/>
</LinearLayout>
  9. Now lets come to MainActivity.java

    public class MainActivity extends AppCompatActivity {
    private ImageView imageView;
    private Button btnChoose, btnUpload;
    public static String BASE_URL = "http://192.168.1.100/AndroidUploadImage/upload.php";
    static final int PICK_IMAGE_REQUEST = 1;
    String filePath;
  10. Now implement OnClickListener interface to our buttons. 
    btnChoose.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        imageBrowse();
    }
});
btnUpload.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        if (filePath != null) {
            imageUpload(filePath);
        } else {
            Toast.makeText(getApplicationContext(), "Image not selected!", Toast.LENGTH_LONG).show();
        }
    }
});
  11. Now we will create a method to choose image from gallery. Create the following method. 
    private void imageBrowse() {
    Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    // Start the Intent
    startActivityForResult(galleryIntent, PICK_IMAGE_REQUEST);
}
  12. To complete the image choosing process we need to override the following method. 
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        if(requestCode == PICK_IMAGE_REQUEST){
            Uri picUri = data.getData();
            filePath = getPath(picUri);
            imageView.setImageURI(picUri);
        }
    }
}
// Get Path of selected image
private String getPath(Uri contentUri) {
    String[] proj = { MediaStore.Images.Media.DATA };
    CursorLoader loader = new CursorLoader(getApplicationContext(),    contentUri, proj, null, null, null);
    Cursor cursor = loader.loadInBackground();
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    String result = cursor.getString(column_index);
    cursor.close();
    return result;
}

    More information about Android Images, read chapter Amazing Facts of Android ImageView.

  13. Now run your application and if you can choose image from gallery then you can move ahead. In below snapshot you can see mine app is working.Image Upload Using Volley
  14. Now we need to create one more method that will upload the image to our server. Create the following method in MainActivity class. 
    private void imageUpload(final String imagePath) {
    SimpleMultiPartRequest smr = new SimpleMultiPartRequest(Request.Method.POST, BASE_URL,
            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {
                    Log.d("Response", response);
                    try {
                        JSONObject jObj = new JSONObject(response);
                        String message = jObj.getString("message");
                        Toast.makeText(getApplicationContext(), message, Toast.LENGTH_LONG).show();
                    } catch (JSONException e) {
                        // JSON error
                        e.printStackTrace();
                        Toast.makeText(getApplicationContext(), "Json error: " + e.getMessage(), Toast.LENGTH_LONG).show();
                    }
                }
            }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            Toast.makeText(getApplicationContext(), error.getMessage(), Toast.LENGTH_LONG).show();
        }
    });
    smr.addFile("image", imagePath);
    MyApplication.getInstance().addToRequestQueue(smr);
}
  15. So the final complete code for our MainActivity.java file would be like 
    public class MainActivity extends AppCompatActivity {
    private ImageView imageView;
    private Button btnChoose, btnUpload;
    public static String BASE_URL = "http://192.168.1.100/AndroidUploadImage/upload.php";
    static final int PICK_IMAGE_REQUEST = 1;
    String filePath;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        imageView = (ImageView) findViewById(R.id.imageView);
        btnChoose = (Button) findViewById(R.id.button_choose);
        btnUpload = (Button) findViewById(R.id.button_upload);
        btnChoose.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                imageBrowse();
            }
        });
        btnUpload.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if (filePath != null) {
                    imageUpload(filePath);
                } else {
                    Toast.makeText(getApplicationContext(), "Image not selected!", Toast.LENGTH_LONG).show();
                }
            }
        });
    }
    private void imageBrowse() {
        Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        // Start the Intent
        startActivityForResult(galleryIntent, PICK_IMAGE_REQUEST);
    }
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == RESULT_OK) {
            if(requestCode == PICK_IMAGE_REQUEST){
                Uri picUri = data.getData();
                Log.d("picUri", picUri.toString());
                Log.d("filePath", filePath);
                imageView.setImageURI(picUri);
            }
        }
    }
    private void imageUpload(final String imagePath) {
        SimpleMultiPartRequest smr = new SimpleMultiPartRequest(Request.Method.POST, BASE_URL,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        Log.d("Response", response);
                        try {
                            JSONObject jObj = new JSONObject(response);
                            String message = jObj.getString("message");
                            Toast.makeText(getApplicationContext(), message, Toast.LENGTH_LONG).show();
                        } catch (JSONException e) {
                            // JSON error
                            e.printStackTrace();
                            Toast.makeText(getApplicationContext(), "Json error: " + e.getMessage(), Toast.LENGTH_LONG).show();
                        }
                    }
                }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                Toast.makeText(getApplicationContext(), error.getMessage(), Toast.LENGTH_LONG).show();
            }
        });
        smr.addFile("image", imagePath);
        MyApplication.getInstance().addToRequestQueue(smr);
    }
    // Get Path of selected image
    private String getPath(Uri contentUri) {
        String[] proj = { MediaStore.Images.Media.DATA };
        CursorLoader loader = new CursorLoader(getApplicationContext(), contentUri, proj, null, null, null);
        Cursor cursor = loader.loadInBackground();
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        String result = cursor.getString(column_index);
        cursor.close();
        return result;
    }
}
  16. Now at last add below permission to your application. 
    <uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
  17. Finally run your app.
  18. You can also download my source code from below.

  • Hi,
    Great post.
    Now what changes should i make in the php file and the android code to send some json string alongside the images such as imageId, datePosted etc

    • update your code:

      smr.addFile("image", imagePath);
smr.addStringParam("imageId", "123");
smr.addStringParam("datePosted", "31-10-2017");

    • add multiDexEnabled true in build.gradle and clear your project then rebuild.

      defaultConfig {
    applicationId "com.example.app"
    ...
    multiDexEnabled true
}

      • sir after doing the above thing ..still it is showing same error
        Error:Execution failed for task ‘:app:transformDexArchiveWithExternalLibsDexMergerForDebug’.
        > java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

    Please kindly provide some solution…

  • Thanks for the excellent tutorial. When I add the “VolleyPlus:+” in my gradle, remaining Volley methods (OnError) which are using original volley library giving error. How can I resolve it?

  • Hello, I need your help, I am working on an application which creates a folder using application (activity) named “Scan” and then I want to upload images to that folder, kindly help me out. what changes can we do in PHP script or how to send a String Folder name with Image Upload. Thank You.

      • On the Server Side. I Want to pass the image to the Folder after its Created using Android app.

        • In upload.php file on server change path in this line –
          // Path to move uploaded files
          $target_path = dirname(__FILE__).’/uploads/’;
          for example if you want to save the image in “Scan” folder then replace “uploads” with “Scan” –
          // Path to move uploaded files
          $target_path = dirname(__FILE__).’/Scan/’;

          • That will upload the File to the Pre-Created Folder, named “Scan”. I want to create a folder using one Activity of android and pass this image to the folder created from that activity. For Better Understanding user creates a folder in htdocs/training/printer named HP10c after that, the location should be passed to next activity of Image Upload where the image is uploaded to this created folder or directory on the server.

          • You can pass location string from one activity to another using
            Intent intent= new Intent(this ,SecondActivity.class);
            intent.putExtra("folder_path","/folder/path/for/image/");
            startActivity(intent);
            And receive in second activity using following code –
            Intent intent = getIntent();
            String path = intent.getStringExtra("folder_path");
            Now you will have to send this path to server via an ajax call.
            Once you get the path on server, use this code to create folder using php –
            if (!file_exists('path/to/directory')) {
            mkdir('path/to/directory', 0777, true);
            }
            Once the folder is created, send your image file to server and save it to that folder. To remember the path of folder created before sending the image, store it in session variable.

          • Thanks for the Reply, Directory making is Already done using Http Post.
            Problem Lies that the File Upload.php as Stated in the tutorial should be inside the folder created “Scan” to upload images. As you can see upload.php is still on server main directory htdocs folder, not in lampp/htdocs/scan/hp10c as if it’s just created using previous activity.
            Now the upload.php has Target path which is static, dirname(__FILE__)./’upload’/;
            Even if I paste it into printer folder, it will upload the image to printer/uploads, but I want to upload it to /hp810c which is created by the user using Android Application, and Upload.php is outside this.
            I want to know how can we pass Dynamic Path to the PHP Script using Same activity.
            Like $Stringhow= “hp810c”
            target_path= dirname(__FILE__)./Stringhow/
            I am a beginner with android app development your detailed help will be appreciated.

  • If your gradle is not being resolved,
    Uncheck the offline work setting in Gradle settings,
    No need to remove the previous Volley library, They work just fine with volley plus

  • Sir,I am very new learner in android studio.I just copied your above code but got compile error…and noticed red colored the following line which was in the last portion of the function imageUpload().
    MyApplication.getInstance().addToRequestQueue(smr);—–In this line,Myapplication was red i.e, it shows wrong in my pc.
    I want to know the reason.

  • Hello sir, how could i upload an array of images?
    My code for adding the file.
    for (int i =0; i<filePath.size();i++) {
    smr.addFile("image["+i+"]", filePath.get(i));
    }

    In my server side code, i tried returning the image path to show it in my logs, but in only displays the name, not the full path.

  • Hello. I tried adding multiple images by inserting them in an ArrayList:

    for (int i =0; i<filePath.size();i++) {
    smr.addFile("image["+i+"]", filePath.get(i));
    }
    RequestHandler.getInstance(context).addToRequestQueue(smr);

    Now when I display each index in my logcat, it shows the full path.
    ex : /storage/emulated/0/Download/FB_IMG_1534074446574.jpg
    /storage/sdcard1/DCIM/PICTURE CITY/DSC_0454.JPG

    I tried foreach on php. Now tried to display the received array, the full path is shorten down to just the image name.

    $response['imagePath'] = $_FILES['image']['name'];

    this displays [{"imagePath":{"1":"DSC_0454.JPG","0":"FB_IMG_1534074446574.jpg"}} ]

    do you have any idea why? Thanks. BTW the code still works if i only upload one
