How to upload Image on server using Volley?
You can try this method ,which actually worked for ma project.First you have to pick the image from gallery then it must be converted to string and sent via volley to server
// initialize
private int PICK_IMAGE_REQUEST = 1;
//set click listener
Upload.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//method to upload the image
showFileChooser();
}
});
Method to open the gallery and to pick the image
private void showFileChooser() {
Intent pickImageIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
pickImageIntent.setType("image/*");
pickImageIntent.putExtra("aspectX", 1);
pickImageIntent.putExtra("aspectY", 1);
pickImageIntent.putExtra("scale", true);
pickImageIntent.putExtra("outputFormat",
Bitmap.CompressFormat.JPEG.toString());
startActivityForResult(pickImageIntent, PICK_IMAGE_REQUEST);
}
Add this method.Here the image is actually getting sent to server.
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri filePath = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath);
Bitmap lastBitmap = null;
lastBitmap = bitmap;
//encoding image to string
String image = getStringImage(lastBitmap);
Log.d("image",image);
//passing the image to volley
SendImage(image);
} catch (IOException e) {
e.printStackTrace();
}
}
}
Method to encode the image as string
public String getStringImage(Bitmap bmp) {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] imageBytes = baos.toByteArray();
String encodedImage = Base64.encodeToString(imageBytes, Base64.DEFAULT);
return encodedImage;
}
uploading using volley
private void SendImage( final String image) {
final StringRequest stringRequest = new StringRequest(Request.Method.POST, "URL",
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
Log.d("uploade",response);
try {
JSONObject jsonObject = new JSONObject(response);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(Edit_Profile.this, "No internet connection", Toast.LENGTH_LONG).show();
}
}) {
@Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new Hashtable<String, String>();
params.put("image", image);
return params;
}
};
{
int socketTimeout = 30000;
RetryPolicy policy = new DefaultRetryPolicy(socketTimeout, DefaultRetryPolicy.DEFAULT_MAX_RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
stringRequest.setRetryPolicy(policy);
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(stringRequest);
}
}
You should have to understand the concept to use of volley library and image uploads. Here are some other useful links for image upload and use of volley library.

Note: I have also tested your tutorial.code are ok. Please check your image path properly. If possible then use their php code on any hosted web server. and check their json response and cross check your parameter which you have passed with server script's parameters..
