I am using below code to upload image to server but it is compressing image to lower resolution.
class ImageUploadTask extends AsyncTask<String, Void, String> {
#Override
protected String doInBackground(String... params) {
ByteArrayBody bab;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
URL url = new URL(webAddressToPost);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("enctype", "multipart/form-data");
MultipartEntity entity = new MultipartEntity();
signature_image.compress(Bitmap.CompressFormat.PNG, 100, bos);
byte[] data = bos.toByteArray();
bab = new ByteArrayBody(data, contactNo+"_Signature.png");
entity.addPart("file", bab);
conn.addRequestProperty(entity.getContentType().getName(), entity.getContentType().getValue());
OutputStream os = conn.getOutputStream();
entity.writeTo(conn.getOutputStream());
os.close();
conn.connect();
}
}
How to upload high resolution image to server instead of compressed image?
Your code will compress the image and then uploading to server. Instead use below code to upload image with original resolution to server.
class ImageUploadTask extends AsyncTask<String, Integer, String> {
private String webAddressToPost = "WRITE_YOUR_API_URL_TO_UPLOAD_IMAGE";
#Override
protected void onPreExecute() {
}
#Override
protected String doInBackground(String... params) {
String image_file_type = params[0];
String file_name = params[1];
int i=1;
if (i==1){
int day, month, year;
int second, minute, hour;
GregorianCalendar date = new GregorianCalendar();
day = date.get(Calendar.DAY_OF_MONTH);
month = date.get(Calendar.MONTH);
year = date.get(Calendar.YEAR);
second = date.get(Calendar.SECOND);
minute = date.get(Calendar.MINUTE);
hour = date.get(Calendar.HOUR);
String name=(hour+""+minute+""+second+""+day+""+(month+1)+""+year);
String tag=name+".jpg";
fileName = frontCameraImageUrl.replace(frontCameraImageUrl,tag);
sourceFile = new File(frontCameraImageUrl);
HttpURLConnection conn = null;
DataOutputStream dos = null;
String lineEnd = "\r\n";
String twoHyphens = "--";

int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
if (!sourceFile.isFile()) {
Log.e("uploadFile", "Source File not exist :");
return "0";
}
else
{
try {
// open a URL connection to the Servlet

conn.setRequestProperty("uploaded_file", fileName);
dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\""

I am recording a video and uploading it to server on button click.
At the same time I need to update a table in my database which has 2 columns, named "userId and filename".
I followed a tutorial for uploading a video,now i need to pass the UserId to php page.I don't know how to do that.
I found this Answer but it is giving IOException - stream closed

i want to upload an image and the username from my android application to my server. i developped this code.
in my database i find the image without username ( value 0).i think that i should use the asynctask but i have no idea how to make it. i want to use this method if it's possible.
this is my code:

for this code: i don't know if i should post only the image or the image and the username. that why i make 2 codes.

function with post image only:

If you want to pass an array of FileBody, you can try it like,
reqEntity.addPart("file[]["+i+"]", bab);
This will generate params like
file=>[{"1" => "File" },{"2" => "File"}..]
Hope it clarifies your doubt.
I got solution. I have used like as below. It's working.
public void uploadFileNew(ArrayList<String>IMAGEPTHLIST, ArrayList<String>IMAGENAMELIST) {
try {
HttpClient httpClient = new DefaultHttpClient();
HttpPost postRequest = new HttpPost(upLoadServerUri);
ByteArrayBody bab;
ByteArrayOutputStream bos;
Bitmap bm;
MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);

I am working with the camera on an Android device. I have captured some images and uploaded them to http.
I used an Intent to invoke an existing Android camera application
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, CAMERA_PIC_REQUEST);
I have Button:
btn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
new Thread(new Runnable() {
#Override
public void run() {
int response = uploadFile("sdcad/" + myLocation
+ ".jpg");
}
}).start();
}
});
public int uploadFile(String sourceFileUri) {
String upLoadServerUri = "...";
String fileName = sourceFileUri;
HttpURLConnection conn = null;
DataOutputStream dos = null;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
File sourceFile = new File(sourceFileUri);
if (!sourceFile.isFile()) {
Log.e("uploadFile", "Source File Does not exist");
return 0;
}
try { // open a URL connection to the Servlet
FileInputStream fileInputStream = new FileInputStream(sourceFile);
URL url = new URL(upLoadServerUri);
conn = (HttpURLConnection) url.openConnection(); // Open a HTTP
// connection to
// the URL
conn.setDoInput(true); // Allow Inputs
conn.setDoOutput(true); // Allow Outputs
conn.setUseCaches(false); // Don't use a Cached Copy
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("ENCTYPE", "multipart/form-data");
conn.setRequestProperty("Content-Type",
"multipart/form-data;boundary=" + boundary);
conn.setRequestProperty("uploaded_file", fileName);
dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\""
+ fileName + "\"" + lineEnd);
dos.writeBytes(lineEnd);
bytesAvailable = fileInputStream.available(); // create a buffer of
// maximum size
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
// read file and write it into form...
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0) {
dos.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
// send multipart form data necesssary after file data...
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
// Responses from the server (code and message)
serverResponseCode = conn.getResponseCode();
String serverResponseMessage = conn.getResponseMessage();
Log.i("uploadFile", "HTTP Response is : " + serverResponseMessage
+ ": " + serverResponseCode);
if (serverResponseCode == 200) {
runOnUiThread(new Runnable() {
public void run() {
tv.setText("File Upload Completed.");
Toast.makeText(getApplicationContext(),
"File Upload Complete.", Toast.LENGTH_SHORT)
.show();
}
});
}
// close the streams //
fileInputStream.close();
dos.flush();
dos.close();
} catch (MalformedURLException ex) {
// dialog.dismiss();
ex.printStackTrace();
Toast.makeText(getApplicationContext(), "MalformedURLException",
Toast.LENGTH_SHORT).show();
Log.e("Upload file to server", "error: " + ex.getMessage(), ex);
} catch (Exception e) {
// dialog.dismiss();
e.printStackTrace();
Toast.makeText(getApplicationContext(),
"Exception : " + e.getMessage(), Toast.LENGTH_SHORT).show();
Log.e("Upload file to server Exception",
"Exception : " + e.getMessage(), e);
}
// dialog.dismiss();
return serverResponseCode;
}
Now I would like to to capture sequential images in time-lapse, upload these. How can I achieve this? Thanks.
