Uploading a file from android take ages before calling a function

I'm having a hard time with calling a function when I select on the files.
When I select on a file, it start to take like 10 seconds before it start to call the UploadFile function and then connect to the server, so when I select more files to add, it will take like a minute or so before it start to call the UploadFile function and connect to the server which is wrong. It should have start to call the UploadFile function instantly and connect to the server when I am adding more than one files.
Below is the full code:
public class ComposeActivity extends AppCompatActivity implements AdapterView.OnItemSelectedListener {
private static final int CHOOSE_FILE_REQUESTCODE = 1;
private RecyclerView mFilesDetailRecyclerView;

Cursor cursor = getContentResolver().query(uri, null, null, null, null);
int index = cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME);
Context context = getApplicationContext();
FilePath = RealPathUtil.getRealPath(context, uri);
cursor.moveToFirst();
//mSelectedFilesList.add(cursor.getString(index));
mSelectedFilesList.add(FilePath);
mAdapter.notifyItemInserted(mSelectedFilesList.size());
Log.e("message.......", "caught this.....");
upload_File = new File(FilePath);
FileName = upload_File.getName();
new UploadFile().execute();
} catch (Exception e) {

What I am trying to do is when I select on the file and add more files on my mobile app, I want to call the UploadFile function instantly and connect to my server to upload the file in each time when I select on the file. If the server do not response for 10 seconds and the server is offline, I want to store the data in the sqlite database.
I have been told that I should use multi thread and I should also use retrofit. I am not sure if it would be possible to use HttpUrlConnection method with multi thread to connect to the server and upload the files.
Can you please show me an example of what is the best way I could use to get instantly call to a function and connect to the server using with HttpUrlConnection if that is possible??

You start already wrong with trying to get a real path for an uri.
Remove that code.
Then instead of opening a FileInputStream open an InputStream for the uri
InputStream is = getContentResolvet().openInputStream(uri);

When i select image from recent then image is broken in android | Multiple images from recent

This error occurs mostly times when select images from recent folder
class com.bumptech.glide.load.engine.GlideException: Received null model

Call multiple images select
Sample Preview
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("image/*");
i.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
*gallery*.launch(i);
gallery basically startActivityForResult(i,123) and OnActivityResult method is deprecated, the gallery is alternative which is defined below
ActivityResultLauncher<Intent> gallery = choosePhotoFromGallery();
and choosePhotoFromGallery() is method which is define below
private ActivityResultLauncher<Intent> choosePhotoFromGallery() {
return registerForActivityResult(
new ActivityResultContracts.StartActivityForResult(),
result -> {
try {
if (result.getResultCode() == RESULT_OK) {
if (null != result.getData()) {
if (result.getData().getClipData() != null) {
ClipData mClipData = result.getData().getClipData();
for (int i = 0; i < mClipData.getItemCount(); i++) {
ClipData.Item item = mClipData.getItemAt(i);
Uri uri = item.getUri();
String imageFilePathColumn = getPathFromURI(this, uri);
productImagesList.add(imageFilePathColumn);
}
} else {
if (result.getData().getData() != null) {
Uri mImageUri = result.getData().getData();
String imageFilePathColumn = getPathFromURI(this, mImageUri);
productImagesList.add(imageFilePathColumn);
}
}
} else {
showToast(this, "You haven't picked Image");
productImagesList.clear();
}
} else {
productImagesList.clear();
}
} catch (Exception e) {
e.printStackTrace();
showToast(this, "Something went wrong");
productImagesList.clear();
}
});
}
and getPathFromURI() is method which define below
public String getPathFromURI(Context context, Uri contentUri) {
OutputStream out;
File file = getPath();
try {
if (file.createNewFile()) {
InputStream iStream = context != null ? context.getContentResolver().openInputStream(contentUri) : context.getContentResolver().openInputStream(contentUri);
byte[] inputData = getBytes(iStream);
out = new FileOutputStream(file);
out.write(inputData);
out.close();
return file.getAbsolutePath();
}
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
private byte[] getBytes(InputStream inputStream) throws IOException {
ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream();
int bufferSize = 1024;
byte[] buffer = new byte[bufferSize];
int len = 0;
while ((len = inputStream.read(buffer)) != -1) {
byteBuffer.write(buffer, 0, len);
}
return byteBuffer.toByteArray();
}
and the getPath() is
private File getPath() {
File folder = new File(Environment.getExternalStorageDirectory(), "Download");
if (!folder.exists()) {
folder.mkdir();
}
return new File(folder.getPath(), System.currentTimeMillis() + ".jpg");
}

How to convert Uri image into Base64?

I have write code to convert image from file location into base64. I can easily convert image into base64 from absolute file location like: C:/Users/Java Engineer/Desktop/test/gallery/magar/Kanuglam.jpg , but I can not convert from location like
. I want to convert image to use in android from web-service.
Here is code sample :
/**
* TEST JSON
*/
String convertToJsonArrayWithImageForMovieDetailTest(ResultSet rs) {
System.out.println("I am insied json converter");
JSONArray list = new JSONArray();
JSONObject obj ;
//File file;
File locatedFile;
FileInputStream fileInputStream;
try {
while (rs.next()) {
obj = new JSONObject();
System.out.println("inside RS");
System.out.println("date is there ha ha ");
obj.put("movie_name", rs.getString("name"));
obj.put("movie_gener", rs.getString("type"));
String is_free_stuff = rs.getString("is_free_stuff");
if (is_free_stuff == "no") {
is_free_stuff = "PAID";
} else {
is_free_stuff = "FREE";
}
obj.put("movie_type", is_free_stuff);
//String movie_image = rs.getString("preview_image");
//this does not work
String movie_image = "http://www.hamropan.com/stores/slider/2016-09-10-852311027.jpg";
//this works for me
// file = new File("C:/Users/Java Engineer/Desktop/Nike Zoom Basketball.jpg");
locatedFile = new File(movie_image);
// Reading a Image file from file system
fileInputStream = new FileInputStream(locatedFile);
if (locatedFile == null) {
obj.put("movie_image", "NULL");
} else {
byte[] iarray = new byte[(int) locatedFile.length()];
fileInputStream.read(iarray);
byte[] img64 = com.sun.jersey.core.util.Base64
.encode(iarray);
String imageString = new String(img64);
obj.put("movie_image", imageString);
}
list.add(obj);
}
} catch (Exception e) {
e.printStackTrace();
}
return list.toString();
}
this block of code works for me but it seem slow
public String imageConvertMethod(String url) throws Exception{
ByteArrayOutputStream output = new ByteArrayOutputStream();
try (InputStream input = new URL(url).openStream()) {
byte[] buffer = new byte[512];
for (int length = 0; (length = input.read(buffer)) > 0;) {
output.write(buffer, 0, length);
}
}
byte [] byte_array = output.toByteArray();
byte[] img64 = com.sun.jersey.core.util.Base64
.encode(byte_array);
String imageString = new String(img64);
return imageString;
}

Ok, try this
bitmap = getBitmapFromUrl(image_url);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] array = stream.getByteArray();
encoded_string = Base64.encodeToString(array, 0);
Method wo load image from url
public static Bitmap getBitmapFromURL(String src) {
try {
URL url = new URL(src);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.connect();
InputStream input = connection.getInputStream();
Bitmap myBitmap = BitmapFactory.decodeStream(input);
return myBitmap;
} catch (IOException e) {
e.printStackTrace();
return null;
}
}

#thanks to Fabio Venturi Pastor
Try this:
ImageUri to Bitmap:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == TAKE_PHOTO_CODE && resultCode == RESULT_OK) {
final Uri imageUri = data.getData();
final InputStream imageStream = getContentResolver().openInputStream(imageUri);
final Bitmap selectedImage = BitmapFactory.decodeStream(imageStream);
String encodedImage = encodeImage(selectedImage);
}
}
Encode Bitmap in base64
private String encodeImage(Bitmap bm)
{
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.JPEG,100,baos);
byte[] b = baos.toByteArray();
String encImage = Base64.encodeToString(b, Base64.DEFAULT);
return encImage;
}
Encode from FilePath to base64
private String encodeImage(String path)
{
File imagefile = new File(path);
FileInputStream fis = null;
try{
fis = new FileInputStream(imagefile);
}catch(FileNotFoundException e){
e.printStackTrace();
}
Bitmap bm = BitmapFactory.decodeStream(fis);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.JPEG,100,baos);
byte[] b = baos.toByteArray();
String encImage = Base64.encodeToString(b, Base64.DEFAULT);
//Base64.de
return encImage;
}
output:
reference :
Take picture and convert to Base64

Getting bitmap as null

}
#Override

File directory = null;
try {

HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.connect();
// InputStream input = connection.getInputStream();
bitmap = BitmapFactory.decodeStream(url.openConnection().getInputStream()); //This bitmap is null always
directory = Environment.getExternalStorageDirectory();
// Create a new folder in SD Card
File dir = new File(Environment.getExternalStorageDirectory().getPath() + "/Profile");
if (!directory.exists() && !directory.isDirectory()) {
directory.mkdirs();
}
File mypath = new File(dir,"ProfileImage");
saveFile(mypath, bitmap);
} catch (MalformedURLException e) {
} catch (IOException e) {
}
return directory.getAbsolutePath();
}

try this,
After saving the Image you have to use this
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
Uri contentUri = Uri.fromFile(file);
mediaScanIntent.setData(contentUri);
getApplicationContext().sendBroadcast(mediaScanIntent);
you have to send a broadcast to System ,changes to reflect in the Gallery , so that you image will be shown in the gallery , if not , you have to restart Device for check the downloaded images..
hope it helps you..

I think you have to use Aquery for image download it is very Useful for image download from net.
Here the link for Aquery
