I'm trying to upload image to xampp server, with android-studio and php
But I will not succeed
Please help me
here is my code(java and php):
java code:
in this codes im trying to select picture from gallery and show a dialog and then uploading image...
public final int REQUEST_OPEN_GALLERY = 5;
ProgressDialog dialog;
Thread uploadThread;
String lineEnd = "\r\n";
String twoHyphens = "--";

int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;

public static Handler uploadHandler;
public static String imageProfile = "";
profile_image.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
chooseFile();
}
});
}

cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(info[0]);
final String filePath = cursor.getString(columnIndex);
//Toast.makeText(MainActivity.this,filePath,Toast.LENGTH_SHORT).show();
dialog = ProgressDialog.show(getContext(), "upload", "Uploading file...");
uploadThread = new Thread(new Runnable() {
#Override
public void run() {
uploadFile(filePath);
}
});
uploadThread.start();
}
}
private void uploadFile(String filePath) {
File file = new File(filePath);
try {

URL url = new URL("http://192.168.1.6/zanborak/sabtenam/upload.php");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();

if (connection.getResponseCode() == 200) {
uploadHandler.post(new Runnable() {
#Override
public void run() {
dialog.dismiss();
Toast.makeText(getContext(), "Upload Completed", Toast.LENGTH_SHORT).show();
imageProfile = "";
}
});
}
fileInputStream.close();
dataOutputStream.flush();
dataOutputStream.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
and php:
in this code im trying move the image to "upload" folder...
<?php
include "connect.php";
$rand=microtime();
$path="upload/".$rand.($_FILES["uploaded_file"]["name"]);
move_uploaded_file($_FILES["uploaded_file"]["tmp_name"],$path);
?>

It would be better if you use Retrofit library. it a light library to exchange data & media through Http protocol and await the response.
you can see how to add it as a dependency in official website.
you also need to add Gson serializer dependency in your gradle.
Once done create responsable to get Retrofit object:
public class RetrofitApiClient {
private static final String BASE_URL = "http://192.168.1.6/"; //htt
private static Retrofit retrofit = null;
private static Gson gson = new GsonBuilder()
.serializeNulls()
.setLenient()
.create();
private RetrofitApiClient() {} // So that nobody can create an object with constructor
public static synchronized Retrofit getClient() {
if (retrofit==null) {
int timeOut = 5 * 60;
OkHttpClient client = new OkHttpClient.Builder()
.connectTimeout(timeOut, TimeUnit.SECONDS)
.writeTimeout(timeOut, TimeUnit.SECONDS)
.readTimeout(timeOut, TimeUnit.SECONDS)
.build();
retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(ScalarsConverterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.client(client)
.build();
}
return retrofit;
}
}
Retrofit turns your HTTP API into a Java interface, so create an interface to handle url for the upload
public interface FileService {
#Multipart
#POST("/zanborak/sabtenam/upload.php")
Call<String> UploadImage(
#Part MultipartBody.Part file);
}
Now you can create a class responsable to push your file to the server and wait for the response.
public class ImageUploaderClass {
//listerner for the task
public interface OnSuccessfullTask {
void onSuccess();
void onFailed(String error);
}
public static void uploadImage(String filePath, OnSuccessfullTask task) {
try {
FileService apiInterface = RetrofitApiClient.getClient().create( FileService .class);
File file = new File(filePath);
//create RequestBody instance from file
RequestBody requestFile = RequestBody.create(MediaType.parse("image"), file);
// MultipartBody.Part is used to send also the actual file name
MultipartBody.Part body = MultipartBody.Part.createFormData("uploaded_file", file.getName(), requestFile);
// finally, execute the request
Call<String> call = apiInterface.UploadImage(body);
call.enqueue(new Callback<String>() {
#Override
public void onResponse(#NonNull Call<String> call, #NonNull Response<String> response) {
String responseBody = response.body();
if (responseBody != null) {
if ("ok".equals(responseBody)) {
task.onSuccess();
} else {
task.onFailed(responseBody);
}
} else {
task.onFailed(responseBody);
}
}
#Override
public void onFailure(#NotNull Call<String> call, #NotNull Throwable t) {
task.onFailed(t.getMessage());
}
});
}
catch (Exception ignored){}
}
}
in your Php returns something to the app in case of success or failure
<?php
include "connect.php";
$rand=microtime();
$path="upload/".$rand.($_FILES["uploaded_file"]["name"]);
$r = move_uploaded_file($_FILES["uploaded_file"]["tmp_name"],$path);
if($r){
echo 'ok';
}
else{
echo 'error';
}
?>
Lastly you can call uploadImage in ActivityResult and pass it the file name and the Actions you need in case of success ot failure

Uploading a Image Works on some devices but returns Stream FixedLengthSource .inputStream()

I am developing an android application that uploads an image to a specified directory using PHP and okhttp . Well , the frontend and backend work fine on my personal device , but it crashes on non-Samsung devices.
When I dug into the problem I found out that the server returns :
com.android.okhttp.internal.http.Http1xStream$FixedLengthSource#17768aa).inputStream()
on the non-Samsung devices.
The Java Code of the file Upload is as Follows :
public class UploadGalleryStoryPost {
private Context context;
private String fileName = "", User_Id = "",Type="";
private ProgressDialog progressDialog;
private int serverResponseCode = 0;
private String count = "";
private String fileCount = "";
public UploadGalleryStoryPost(String fileName, Context context, String User_Id, String Type, String count, String fileCount) {
this.fileName = fileName;

App crashes at image upload because of bitmap and nullpointer

I am writing an app to upload images to my server from gallery and from camera
the problem I am having is when i take a picture from the camera and I click my upload button it crashes out of the app
according to the debug logs it has something to do with the bitmap pointing to a null object refrence as well as bitmap failing to decode the stream
there are a few answers on SO pretaining to this but non have worked so far
Error log

How to upload video in android using volley

I am trying to upload a video on the server, I didn't anything on this, please suggest
I can upload the text, that's working,
RequestQueue requestQueue = Volley.newRequestQueue(mContext);
StringRequest stringRequest = new StringRequest(Request.Method.POST, "http://54.146.132.94/webservices/target_response",
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Toast.makeText(mContext, "" + response, Toast.LENGTH_SHORT).show();
Log.i("error", response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(mContext, "" + error.toString(), Toast.LENGTH_SHORT).show();
Log.i("error", error.toString());
}
}) {
#Override
protected Map<String, String> getParams() {
// Posting parameters to login url
Map<String, String> params = new HashMap<String, String>();
params.put("I_trails", String.valueOf(itr));
params.put("E_trails", String.valueOf(et));
params.put("D_trails", String.valueOf(dt));
params.put("N_trails", String.valueOf(nt));
params.put("user_id", String.valueOf(get_id));
params.put("target_id", String.valueOf(get_target_id));
params.put("session_date", date);
params.put("data_mode", data_mode);
params.put("mode", mode);
params.put("link", link);
// params.put("video", selectedPath);
params.put("time", time_upload_real);
params.put("location_id", LocID);
params.put("No_of_trails", String.valueOf(notr));
/*params.put("comment", my_comment);*/
return params;
}
};
// Adding the StringRequest object into requestQueue.
requestQueue.add(stringRequest);
here the code to upload video, please let me know how to upload this video with the data, that I am uploading.
if (null != selectedPath && !selectedPath.isEmpty()){
Toast.makeText(mContext, "selected path: "+selectedPath, Toast.LENGTH_SHORT).show();
new Thread(new Runnable() {
#Override
public void run() {
//creating new thread to handle Http Operations
uploadFile(selectedPath);
}
}).start();
then,
public int uploadFile(final String selectedPath){
int serverResponseCode = 0;
HttpURLConnection connection;
DataOutputStream dataOutputStream;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead,bytesAvailable,bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
File selectedFile = new File(selectedPath);
try {
FileInputStream fileInputStream = new FileInputStream(selectedFile);
URL url = new URL("http://54.146.132.94/webservices/target_response");
connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);//Allow Inputs
connection.setDoOutput(true);//Allow Outputs
connection.setUseCaches(false);//Don't use a cached Copy
connection.setRequestMethod("POST");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("ENCTYPE", "multipart/form-data");
connection.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
connection.setRequestProperty("video",selectedPath);
//creating new dataoutputstream
dataOutputStream = new DataOutputStream(connection.getOutputStream());
//writing bytes to data outputstream
dataOutputStream.writeBytes(twoHyphens + boundary + lineEnd);
dataOutputStream.writeBytes("Content-Disposition: form-data; name=\"video\";filename=\""
+ selectedPath + "\"" + lineEnd);
dataOutputStream.writeBytes(lineEnd);
//returns no. of bytes present in fileInputStream
bytesAvailable = fileInputStream.available();
//selecting the buffer size as minimum of available bytes or 1 MB
bufferSize = Math.min(bytesAvailable,maxBufferSize);
//setting the buffer as byte array of size of bufferSize
buffer = new byte[bufferSize];
//reads bytes from FileInputStream(from 0th index of buffer to buffersize)
bytesRead = fileInputStream.read(buffer,0,bufferSize);
//loop repeats till bytesRead = -1, i.e., no bytes are left to read
while (bytesRead > 0){
//write the bytes read from inputstream
dataOutputStream.write(buffer,0,bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable,maxBufferSize);
bytesRead = fileInputStream.read(buffer,0,bufferSize);
}
dataOutputStream.writeBytes(lineEnd);
dataOutputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
serverResponseCode = connection.getResponseCode();
String serverResponseMessage = connection.getResponseMessage();
//closing the input and output streams
fileInputStream.close();
dataOutputStream.flush();
dataOutputStream.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (ProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
// dialog.dismiss();
return serverResponseCode;
}

Intent intent = new Intent();
intent.setType("video/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Complete action using"), PICK_FROM_GALLERY);
and after selecting video
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode != RESULT_OK) return;
if (requestCode == PICK_FROM_GALLERY) {
Uri aa = data.getData();
mVideoURI = Uri.parse(String.valueOf(aa));
}
}
dont forget to use private Uri mVideoURI;
at top
inside your post volley method use :
#Override
protected Map<String, DataPart> getByteData() {
Map<String, DataPart> params = new HashMap<>();
/// photo field in link
if (mVideoURI != null) {
params.put("video", new DataPart("file_avatar.mp4", UploadHelper.getFileDataFromDrawable(getActivity(), mVideoURI)));
}
return params;
}
UPDATE
1- CREATE BroadcastHelper CLASS :
public class BroadcastHelper {
public static final String BROADCAST_EXTRA_METHOD_NAME = "INPUT_METHOD_CHANGED";
public static final String ACTION_NAME = "hassan.scott";
private static final String UPDATE_LOCATION_METHOD = "update";
public static void sendInform(Context context, String method) {
Intent intent = new Intent();
intent.setAction(ACTION_NAME);
intent.putExtra(BROADCAST_EXTRA_METHOD_NAME, method);
try {
context.sendBroadcast(intent);
} catch (Exception e) {
e.printStackTrace();
}
}
public static void sendInform(Context context, String method, Intent intent) {
intent.setAction(ACTION_NAME);
intent.putExtra(BROADCAST_EXTRA_METHOD_NAME, method);
try {
context.sendBroadcast(intent);
} catch (Exception e) {
e.printStackTrace();
}
}
}
2- Send intent from your adapter
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent url = new Intent("url");
url ("url_adapter",item.get(position).getURL());
BroadcastHelper.sendInform(context,"url",url);
}
});
3- in your fragment this use :
Receiver receiver;
boolean isReciverRegistered = false;
#Override
public void onResume() {
super.onResume();
if (receiver == null) {
receiver = new Receiver();
IntentFilter filter = new IntentFilter(BroadcastHelper.ACTION_NAME);
getActivity().registerReceiver(receiver, filter);
isReciverRegistered = true;
}
}
#Override
public void onDestroy() {
if (isReciverRegistered) {
if (receiver != null)
getActivity().unregisterReceiver(receiver);
}
super.onDestroy();
}
private class Receiver extends BroadcastReceiver {
#Override
public void onReceive(Context arg0, Intent arg1) {
Log.v("r", "receive " + arg1.getStringExtra(BroadcastHelper.BROADCAST_EXTRA_METHOD_NAME));
String methodName = arg1.getStringExtra(BroadcastHelper.BROADCAST_EXTRA_METHOD_NAME);
if (methodName != null && methodName.length() > 0) {
Log.v("receive", methodName);
switch (methodName) {
case "url":
/* call post method here */
default:
break;
}
}
}
}
UploadHelper Class :
public class UploadHelper {
/**
* Turn drawable resource into byte array.
*
* #param context parent context
* #param id drawable resource id
* #return byte array
*/
public static byte[] getFileDataFromDrawable(Context context, int id) {
Drawable drawable = ContextCompat.getDrawable(context, id);
Bitmap bitmap = ((BitmapDrawable) drawable).getBitmap();
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, byteArrayOutputStream);
return byteArrayOutputStream.toByteArray();
}
/**
* Turn drawable into byte array.
*
* #return byte array
*/
public static byte[] getFileDataFromDrawable(Context context, Uri uri) {
// Bitmap bitmap = ((BitmapDrawable) drawable).getBitmap();
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
try {
InputStream iStream = context.getContentResolver().openInputStream(uri);
int bufferSize = 2048;
byte[] buffer = new byte[bufferSize];
// we need to know how may bytes were read to write them to the byteBuffer
int len = 0;
if (iStream != null) {
while ((len = iStream.read(buffer)) != -1) {
byteArrayOutputStream.write(buffer, 0, len);
}
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
// bitmap.compress(Bitmap.CompressFormat.JPEG, 100, byteArrayOutputStream);
return byteArrayOutputStream.toByteArray();
}
}

Volley wasn't really meant for video uploading. It is better suited to large in number - small in size uploads/downloads. I would recommend using a different method to upload your video.
Volley is not suitable for large download or streaming operations,
since Volley holds all responses in memory during parsing. For large
download operations, consider using an alternative like
DownloadManager.*

Upload image to server and store path with text values into MySQL

I am still a beginner of Andorid programming and would need some help to the following:
What I currently have are 2 codes, which the first uploads an image to the server and stores the path into a MySQL table. The second code stores 2 EditText field values into a MySQL database table.
What I actually want is to combine both codes, so it should be possible to upload an image to the server and then store the associated string path with 2 EditText field values into a MySQL database table at once.
1.) For uploading image and to store the string path into MySQL table I have following codes:
-Upload Image to server (JAVA side):
public class MainActivity extends Activity implements OnClickListener {
private TextView messageText;
private Button uploadButton, btnselectpic;
private ImageView imageview;

2.) For inserting EditText values from Android to MySQL Database I have following codes:

httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
Log.e("pass 1", "connection success ");
}
catch(Exception e)
{

}
try
{
BufferedReader reader = new BufferedReader
(new InputStreamReader(is,"iso-8859-1"),8);
StringBuilder sb = new StringBuilder();
while ((line = reader.readLine()) != null)
{
sb.append(line + "\n");
}
is.close();
result = sb.toString();
Log.e("pass 2", "connection success ");
}
catch(Exception e)
{
Log.e("Fail 2", e.toString());
}
try
{

{

}
print(json_encode($flag));
mysql_close($con);
?>
HOW CAN I COMBINE 1.) and 2.)? I tried it almost 3 days but it simply does not work and I despair :S. Hope somebody can help.
Thanks in advance.

Combine these two code file in same activity first by calling them in two different functions
and on uploading image file take image name from imagepath string using substring function
and send that image name along with JSON data and in server side while inserting store that image path in the format ip_address/image_upload_folder/imagename.

Trying to use Async with image upload to webserver android?

I am trying to use Async to be more efficient and to allow for image uploads to my webserver I have tried various methods but there is always something not working...
Here is my latest code but having problems with the return being an Int and if I change the

This is the error

I see many several problems here. First, you almost never (if ever) want to call runOnUiThread() from AsyncTask. Every method of AsyncTask runs on the UI except for doInBackground() so this usually isn't needed and often causes problems. Update the UI with the correct methods depending on what you are doing.
Second, I think you misunderstand what doInBackground() is returning. Its result is returned to onPostExecute() which is the 3rd param in your class declaration
private class doFileUpload extends AsyncTask <String, Void, String> {
So this means that onPostExecute() (which I don't see you overriding) should expect a String and that is what doInBackground() should return. So you should convert your return variables to String if you want to pass a String to onPostExecute()
AsyncTask Docs
Typically
progressDialog.dismiss();
is called in onPostExecute() and
progressDialog.show();
would be called in onPreExecute() when using an AsyncTask. Then you don't have to create a new Thread in your onClick().
