I have this task to send a picture i take with my app to a webserver. this is my camera activity where i would like to send the image in the onActivityResult method. I have trouble finding up to date solutions to this as all i can find seems to be using MultipartEntity which is now deprecated.
package com.ndjk;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.net.Uri;
import android.os.Bundle;
import android.widget.ImageView;
public class CameraActivity extends Activity {
private static final int CAMERA_REQUEST = 1888;
public ImageView imageView;
public static final String URI_PATH = "Uri";
Uri imageUri = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_frontpage);
imageView = (ImageView) findViewById(R.id.pictureImageView);
open();
}
public void open() {
Intent cameraIntent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
Bitmap bp = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(bp);
Intent frontPageIntent = new Intent(this, FrontPageActivity.class);
imageUri = data.getData();
frontPageIntent.putExtra(URI_PATH, imageUri.toString());
frontPageIntent.putExtra("MapPhoto", bp);
startActivity(frontPageIntent);
}
}

You can open camera with this code:
private static final int RESULT_TAKE_PHOTO = 1;
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, RESULT_TAKE_PHOTO);
Your onActivityResult
must be like this :
if (resultCode == RESULT_OK) {
File file = null;
String filePath = null;
try {
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]);
filePath = cursor.getString(columnIndex);
cursor.close();
rotateDegree = getCameraPhotoOrientation(getApplicationContext(), selectedImage, picturePath);
bmp = BitmapFactory.decodeFile(picturePath);
bmp = rotateImage(bmp, rotateDegree);
file = new File(filePath);
FileOutputStream fOut = new FileOutputStream(file);
bmp.compress(Bitmap.CompressFormat.JPEG, 70, fOut);
fOut.flush();
fOut.close();
resultCode=0;
} catch (Exception e) {
e.printStackTrace();
}
}
So if take the picture You can use this AsyncTask for sending. You can show a progress bar while sending file to server. It's working for me.
public class SendFile extends AsyncTask<String, Integer, Integer> {
private Context conT;
private ProgressDialog dialog;
private String SendUrl = "";
private String SendFile = "";
private String Parameters = "";
private String result;
public File file;
SendFile(Context activity, String url, String filePath, String values) {
conT = activity;
dialog = new ProgressDialog(conT);
SendUrl = url;
SendFile = filePath;
Parameters = Values;
}
@Override
protected void onPreExecute() {
file = new File(SendFile);
dialog.setMessage("Please Wait..");
dialog.setCancelable(false);
dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
dialog.setMax((int) file.length());
dialog.show();
}
@Override
protected Integer doInBackground(String... params) {
HttpURLConnection connection = null;
DataOutputStream outputStream = null;
InputStream inputStream = null;
String twoHyphens = "--";
String boundary = "*****"
+ Long.toString(System.currentTimeMillis()) + "*****";
String lineEnd = "\r\n";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 512;
String[] q = SendFile.split("/");
int idx = q.length - 1;
try {
FileInputStream fileInputStream = new FileInputStream(file);
URL url = new URL(SendUrl);
connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);
connection.setRequestMethod("POST");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("User-Agent",
"Android Multipart HTTP Client 1.0");
connection.setRequestProperty("Content-Type",
"multipart/form-data; boundary=" + boundary);
outputStream = new DataOutputStream(
connection.getOutputStream());
outputStream.writeBytes(twoHyphens + boundary + lineEnd);
outputStream
.writeBytes("Content-Disposition: form-data; name=dosya; filename=\""
+ q[idx] + "\"" + lineEnd);
outputStream.writeBytes("Content-Type: image/jpg" + lineEnd);
outputStream.writeBytes("Content-Transfer-Encoding: binary"
+ lineEnd);
outputStream.writeBytes(lineEnd);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
int boyut = 0;
while (bytesRead > 0) {
boyut += bytesRead;
outputStream.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
dialog.setProgress(boyut);
}
outputStream.writeBytes(lineEnd);
String[] posts = Bilgiler.split("&");
int max = posts.length;
for (int i = 0; i < max; i++) {
outputStream.writeBytes(twoHyphens + boundary + lineEnd);
String[] kv = posts[i].split("=");
outputStream
.writeBytes("Content-Disposition: form-data; name=\""
+ kv[0] + "\"" + lineEnd);
outputStream.writeBytes("Content-Type: text/plain"
+ lineEnd);
outputStream.writeBytes(lineEnd);
outputStream.writeBytes(kv[1]);
outputStream.writeBytes(lineEnd);
}
outputStream.writeBytes(twoHyphens + boundary + twoHyphens
+ lineEnd);
inputStream = connection.getInputStream();
result = this.convertStreamToString(inputStream);
Log.v("TAG","result:"+result);
fileInputStream.close();
inputStream.close();
outputStream.flush();
outputStream.close();
} catch (Exception e) {
}
return null;
}
@Override
protected void onProgressUpdate(Integer... progress) {
dialog.setProgress(progress[0]);
}
@Override
protected void onPostExecute(Integer result1) {
dialog.dismiss();
};
private String convertStreamToString(InputStream is) {
BufferedReader reader = new BufferedReader(
new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return sb.toString();
}
and if you are sending to PHP server, this code will help you.
<?php
$file_path = "test/";
$username= $_POST["username"];
$password= $_POST["password"];
$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
echo "success";
} else{
echo "fail";
}
?>
Edit - 2:
you can call this AsyncTask
like :
String FormData = "username=" + Session.getUsername()
+ "&password=" + Session.getPassword() ;
SendFile SendIt= new SendFile(this, upLoadServerUri, filePath,FormData);
SendIt.execute();

As an alternative, I would highly recommend using Retrofit a REST library from Square. Retrofit
You would create a Java interface like this:
@Multipart
@POST("/webservice/{userid}/avatar.json")
Object uploadImage(
@Header("Rest-User-Token") String token,
@Path("userid") String userId,
@Part("FileData") TypedFile pictureFile
);
Then it is just a case of converting the Intent data to a File object, and than creating a TypedFile as follows:
TypedFile in = new TypedFile("image/jpeg", imageFile);

I think the answer is here: https://stackoverflow.com/a/19196621/1652236
You should use MultipartEntityBuilder as an alternative
