Image uploading to Cloudinary Failed in Android

I am trying to upload an image to Cloudinary after clicking the image from the camera.
The camera is working fine but after clicking the image, the application is crashing again and again. Tried to debug it but not getting where I am having the error.

I tried to hard code the sample image URL's but still it is not working.
May be the issue is with this line
cloudinary.uploader().upload(photoFile.getAbsolutePath(), ObjectUtils.emptyMap());
public static final int TAKE_PHOTO_REQUEST = 0;
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == TAKE_PHOTO_REQUEST) {
if (resultCode == RESULT_OK) {
//File to upload to cloudinary
Toast.makeText(this, "Pakistan Zinabad", Toast.LENGTH_SHORT).show();
Map config = new HashMap();
config.put("cloud_name", "nomancloud");
config.put("api_key", "myKey");
config.put("api_secret", "mySecretApi");
Cloudinary cloudinary = new Cloudinary(config);
try {
cloudinary.uploader().upload(photoFile.getAbsolutePath(), ObjectUtils.emptyMap());
} catch (IOException e) {
e.printStackTrace();
}
} else if (resultCode == RESULT_CANCELED) {
// User cancelled the image capture
//finish();
}
}
}
private File createImageFile() throws IOException {
// Create an image file name
String imageFileName = "capturedImage";
File storageDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
return image;
}
#Override
public void onClick(View v) {
Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePhotoIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
photoFile = null;
try {
photoFile = createImageFile();
}
catch (IOException ex) {
// Error occurred while creating the File
}
// Continue only if the File was successfully created
if (photoFile != null) {
takePhotoIntent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photoFile));
startActivityForResult(takePhotoIntent, TAKE_PHOTO_REQUEST);
}
}
}

Can you try using:
Map uploadResult = cloudinary.uploader().upload("http://res.cloudinary.com/demo/image/upload/sample.jpg", ObjectUtils.emptyMap());
And print the RuntimeException/uploadResult?

Try using the MediaManager class for android provided by Cloudinary. You will need to call the dispatch() method which will run on a background thread. Basically you are getting NetworkOnMainThread exception which means you are doing network calls on the UI thread with Android does not allow. Check the documentation, its easy.
String requestId = MediaManager.get().upload("imageFile.jpg")
.unsigned("sample_preset")
.dispatch();

MediaStore.Images.Media.insertImage returns null in some devices

Possibly Duplicate but did not find any solution.
I am trying to modify image and saving it to device using MediaStore. with following code -:
public class Utils {
private Utils() {
}
static Uri getUri(Context context, Bitmap bitmap) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = MediaStore.Images.Media.insertImage(context.getContentResolver(), bitmap, "Title", null); //returning null in some devices
Log.d("TAG", "getUri: "+path);
return Uri.parse(path); //this is returning null which cause the app crash
}
static Bitmap getBitmap(Context context, Uri uri) throws IOException {
return MediaStore.Images.Media.getBitmap(context.getContentResolver(), uri);
}
}
This code is working well in most of devices but the problem is that MediaStore.Images.Media.insertImage returning null in some devices like -:
1. Samsung J7(2016)
2. LG Magna LTE
3. Android Emulator API 21
I am surprised this app is working in Android Emulator API 26 . but getting crashed on Android Emulator API 21
I have searched google and I have also find the same question here but not find any sufficient answer.
NOTE - : I have used Runtime Permission for Read/Write External Storage
But still getting crash in mentioned devices. Below is my crash log-:

Thanks

Instead of using below code-:
String path = MediaStore.Media.insertImage(context.getContentResolver(),bitmap,"Title",null);
Use this code(below)-:
ContentValues values=new ContentValues();
values.put(MediaStore.Images.Media.TITLE,"Title");
values.put(MediaStore.Images.Media.DESCRIPTION,"From Camera");
Uri path=getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,values);
pass values as null if it is not working.

protected void onActivityResult(int requestCode, int resultCode,Intent data) {
if (requestCode == RequestPermissionCode && resultCode == RESULT_OK) {
try {
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, filePathColumn, null, null, null);
if (cursor == null)
return;
// find the file in the media area
cursor.moveToLast();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String filePath = "file:///"+cursor.getString(columnIndex);
cursor.close();
actualImage = FileUtil.from(this,Uri.parse(filePath));
actualImageView.setImageBitmap(BitmapFactory.decodeFile(actualImage.getAbsolutePath()));
} catch (Exception e) {
Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_LONG).show();
}
}
}
Use onActvittyResult method i hope it will work.

java.lang.RuntimeException: Unable to resume activity Attempted to access a cursor after it has been closed

I have following method to pass selected image path to another activity:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
Log.d("fsd", "onActivityResult: ");
Intent intent = new Intent(getApplicationContext(), AddContentImage.class);
Bundle b = new Bundle();
b.putString("path", selectedImagePath);
intent.putExtras(b);
startActivity(intent);
}
}
}
Which is actually working fine, but I gets following error, when back button is pressed.
java.lang.RuntimeException: Unable to resume activity : android.database.StaleDataException: Attempted to access a cursor after it has been closed.

This error only occurs if second activity is opened from onActivityResult.
Edited:
getpath method
public String getPath(Uri uri) {
// just some safety built in
if( uri == null ) {
// TODO perform some logging or show user feedback
return null;
}
// try to retrieve the image from the media store first
// this will only work for images selected from gallery
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
if( cursor != null ){
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String path = cursor.getString(column_index);
cursor.close();
return path;
}
// this is our fallback here
return uri.getPath();
}
How can I solve this error?

First, managedQuery() has been deprecated for over six years. Do not use it. Use a CursorLoader, or use ContentResolver and query() on some form of background thread.
Second, be sure to follow the instructions of the things that you use. In this case, you missed the instructions for using managedQuery():
Warning: Do not call close() on a cursor obtained using this method, because the activity will do that for you at the appropriate time.
Beyond that, a Uri does not point to a file in most cases, and so you cannot get a "real path" to that file.

Cursor error - Retrieving image from gallery

Currently I'm trying to retrieve the location of an image in my gallery and convert it into a File so that I can upload it to the internet. But I received this error instead. The error happened when I open the gallery and on selecting the image it crash instead. I'm not so well versed in android and still consider myself a beginner. So if you decided to vote down my question please tell me the reason why so that I can learn. Thank you.

The code that I used to retrieved the image is down below:-
private String getRealPathFromURI(Uri contentURI) {
String result;
Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);
if (cursor == null) { // Source is Dropbox or other similar local file path
result = contentURI.getPath();
} else {
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
result = cursor.getString(idx); // getting error here ; it returns -1
cursor.close();
}
return result;
}

You have to add column name MediaStore.Images.Media.DATA with query.
Update getRealPathFromURI() as below:
private String getRealPathFromURI(Uri contentURI) {
String result;
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(contentURI, filePathColumn, null, null, null);
if (cursor == null) { // Source is Dropbox or other similar local file path
result = contentURI.getPath();
} else {
cursor.moveToFirst();
int idx = cursor.getColumnIndex(filePathColumn[0]);
result = cursor.getString(idx);
cursor.close();
}
return result;
}
In you onActivityResult() method:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
try {
// When an Image is picked
if (requestCode == YOUR_REQUEST_CODE && resultCode == RESULT_OK
&& null != data) {
// Get the Image from data
Uri selectedImage = data.getData();
// Get real path
String imageRealPath = getRealPathFromURI(selectedImage);
// Do something
}
} catch (Exception e) {
Toast.makeText(this, "Something went wrong", Toast.LENGTH_LONG)
.show();
}
}
Make sure you have added permission:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
Here is a good tutorial. Hope this will help~

You should not try to get a file path and construct a file object from that uri to upload the file. You dont need that all. Use the uri directly to open an inputstream.
Somewhere you will now have
FileInputStream fis = new FileInputStream(path);
Replace that by
InputStream is = getContentResolver().openInputStream(data.getData());

This supports APIs below and above 19, including 19:
public String getRealPathFromURI(Uri uri) {
Cursor cursor = this.getContentResolver().query(uri, null, null, null, null);
String result;
// for API 19 and above
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
cursor.moveToFirst();
String image_id = cursor.getString(0);
image_id = image_id.substring(image_id.lastIndexOf(":") + 1);
cursor.close();
cursor = this.getContentResolver().query(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, null, MediaStore.Images.Media._ID + " = ? ", new String[]{image_id}, null);
}
cursor.moveToFirst();
result = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
cursor.close();
return result;
}

Java - Android - Main thread exception uploading by FTP

I'm developing a very simple app in which you press a button, the camera is launched, you take a photo and this photo is stored in the SD card and then uploaded to my FTP. I'm using simpleFTP library to connect to my FTP but I don't know why I'm getting the error below when uploading the file.
This is the relevant part of the code from the main class:
private void dispatchTakePictureIntent() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
photoFile = null;
try {
photoFile = createImageFile();
Log.v("photoFile", photoFile.toString());
} catch (IOException ex) {
// Error occurred while creating the File
}
// Continue only if the File was successfully created
if (photoFile != null) {
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
}
}
}
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = "file:" + image.getAbsolutePath();
return image;
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
//The image is already stored in the phone, let's open it up from there
File imgFile = photoFile;
if(imgFile.exists()){
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
mImageView.setImageBitmap(myBitmap);
}
new UploadFTP<File>().doInBackground(imgFile);
}
}
And this is the class that handle's the AsycnTask:
class UploadFTP<File> extends AsyncTask<File, Void, Void> {
#Override
protected Void doInBackground(File... params) {
File file = params[0];
try
{
SimpleFTP ftp = new SimpleFTP();
// Connect to an FTP server on port 21.
ftp.connect("ftp.myurl", 21, "myuser", "mypass");
// Set binary mode.
ftp.bin();
// Change to a new working directory on the FTP server.
ftp.cwd("www/xxx");
// Upload files.
ftp.stor(new java.io.File(String.valueOf(file)));
ftp.disconnect();
}
catch (IOException e)
{
e.printStackTrace();
}
return null;
}
}
And here the error:
