I am trying to create a facial/emotion detection application for my dissertation and have hit the wall that has stopped me from progressing and I cant figure out the reason why it is preventing the image saving to the directory of the phone. It seems to be saving to the SD card, but I dont use an SDcard in my phone / an emulated DCIM.
file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM)+ "/" + UUID.randomUUID(), toString()+ ".jpg");
ImageReader.OnImageAvailableListener readerListener = new ImageReader.OnImageAvailableListener() {
#Override
public void onImageAvailable(ImageReader imageReader) {
Image image = null;
try {
image = reader.acquireLatestImage();
ByteBuffer buffer = image.getPlanes() [0].getBuffer();
byte[] bytes = new byte[buffer.capacity()];
buffer.get(bytes);
save(bytes);
} catch (IOException e)
{
e.printStackTrace();
}
finally {
{
if (image != null)
image.close();
}
}
}
This is the code I have to create the file and save to the location, I have tried other solutions but they throw out errors.
File folder = new File(Environment.getExternalStorageDirectory() + "/CustomFolder");
File file;
if (!folder.exists()) {
boolean success = folder.mkdir();
if (success){
file = new File(folder.getPath() + "/" + UUID.randomUUID(), toString()+ ".jpg");
}else {
Toast.makeText(FacialDetection.this, "Failed to save file to folder", Toast.LENGTH_SHORT).show();
}
}else{
file = new File(folder.getPath() + "/" + UUID.randomUUID(), toString()+ ".jpg");
}
ImageReader.OnImageAvailableListener readerListener = new ImageReader.OnImageAvailableListener() {
#Override
public void onImageAvailable(ImageReader imageReader) {
Image image = null;
try {
image = reader.acquireLatestImage();
ByteBuffer buffer = image.getPlanes() [0].getBuffer();
byte[] bytes = new byte[buffer.capacity()];
buffer.get(bytes);
save(bytes);
} catch (IOException e)
{
e.printStackTrace();
}
finally {
{
if (image != null)
image.close();
}
}
}
private void save(byte[] bytes) throws IOException {
OutputStream outputStream = null;
try {
outputStream = new FileOutputStream(***file***);
outputStream.write(bytes);
}finally {
if (outputStream != null)
outputStream.close();
}
}
};
reader.setOnImageAvailableListener(readerListener, mBackgroundHandler);
final CameraCaptureSession.CaptureCallback captureListener = new CameraCaptureSession.CaptureCallback() {
#Override
public void onCaptureCompleted(#NonNull CameraCaptureSession session, #NonNull CaptureRequest request, #NonNull TotalCaptureResult result) {
super.onCaptureCompleted(session, request, result);
Toast.makeText(FacialDetection.this, "Saved " + ***file***, Toast.LENGTH_SHORT).show();
createCameraPreview();
}
};
The updated code, stuff bold and italic is what is throwing errors
I will advise you to create your own custom folder location this way:
File folder = new File(Environment.getExternalStorageDirectory() + "/CustomFolder");
File file;
if (!folder.exists()) {
boolean success = folder.mkdir();
if (success){
file = new File(folder.getPath() + "/" + UUID.randomUUID(), toString()+ ".jpg");
}else {
//Some message
}
}else {
file = new File(folder.getPath() + "/" + UUID.randomUUID(), toString()+ ".jpg");
}
//The rest of your code...
You're calling:
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM)
I would speculate that .getExternalStoragePublicDirectory() means get directory on SD card. Is there a getInternal... method?
//Create folder !exist
String folderPath = Environment.getExternalStorageDirectory() +"/myFoldername";
File folder = new File(folderPath);
if (!folder.exists()) {
File wallpaperDirectory = new File(folderPath);
wallpaperDirectory.mkdirs();
}
//create a new file
newFile = new File(folderPath, newPhoto.getName());
if (newFile != null) {
// save image here
Uri relativePath = Uri.fromFile(newFile);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, relativePath);
startActivityForResult(intent, CAMERA_REQUEST);
}
I'm a newbie about android programming
I would like to create folder for store image from my app when user click save
I can save image to my device
but I have no idea to create specific folder ,How to create folder??
thanks for your help!
and sorry my english is not good.

This isn't anything related to S3.
ENOENT (No such file or directory) is a local error: file not found.
Take a very close look at the path in the error message. I've included the path here, and added some line breaks for readability. I did not otherwise edit this, and, importantly, I did not paste any of it here more than once:
/data/user/0
/competent.groove.feetport
/files/data/user/0
/competent.groove.feetport
/app_imageDir/IMG_20161122_073058.jpg
I'm not saying that this is wrong, but it certainly looks wrong. It certainly looks like you're trying to upload the file from a path that you have incorrectly constructed, with some duplication in the directory structure... and there's no such directory, no such file.
unfortunately the solutions I've found didn't work on android 5.1.1.
I have a bitmap called source. I need to save it directly to my phone's gallery. My manifest contains <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Can you give me a working method to do this?
There were several different ways to do it before API 29 (Android Q) but all of them involved one or a few APIs that are deprecated with Q. In 2019, here's a way to do it that is both backward and forward compatible:
(And since it is 2019 so I will write in Kotlin)
/// #param folderName can be your app's name
private fun saveImage(bitmap: Bitmap, context: Context, folderName: String) {
if (android.os.Build.VERSION.SDK_INT >= 29) {
val values = contentValues()
values.put(MediaStore.Images.Media.RELATIVE_PATH, "Pictures/" + folderName)
values.put(MediaStore.Images.Media.IS_PENDING, true)
// RELATIVE_PATH and IS_PENDING are introduced in API 29.
val uri: Uri? = context.contentResolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values)
if (uri != null) {
saveImageToStream(bitmap, context.contentResolver.openOutputStream(uri))
values.put(MediaStore.Images.Media.IS_PENDING, false)
context.contentResolver.update(uri, values, null, null)
}
} else {
val directory = File(Environment.getExternalStorageDirectory().toString() + separator + folderName)
// getExternalStorageDirectory is deprecated in API 29
if (!directory.exists()) {
directory.mkdirs()
}
val fileName = System.currentTimeMillis().toString() + ".png"
val file = File(directory, fileName)
saveImageToStream(bitmap, FileOutputStream(file))
if (file.absolutePath != null) {
val values = contentValues()
values.put(MediaStore.Images.Media.DATA, file.absolutePath)
// .DATA is deprecated in API 29
context.contentResolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values)
}
}
}
private fun contentValues() : ContentValues {
val values = ContentValues()
values.put(MediaStore.Images.Media.MIME_TYPE, "image/png")
values.put(MediaStore.Images.Media.DATE_ADDED, System.currentTimeMillis() / 1000);
values.put(MediaStore.Images.Media.DATE_TAKEN, System.currentTimeMillis());
return values
}
private fun saveImageToStream(bitmap: Bitmap, outputStream: OutputStream?) {
if (outputStream != null) {
try {
bitmap.compress(Bitmap.CompressFormat.PNG, 100, outputStream)
outputStream.close()
} catch (e: Exception) {
e.printStackTrace()
}
}
}
Also, before calling this, you need to have WRITE_EXTERNAL_STORAGE first.
Use this one:
private void saveImage(Bitmap finalBitmap, String image_name) {
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root);
myDir.mkdirs();
String fname = "Image-" + image_name+ ".jpg";
File file = new File(myDir, fname);
if (file.exists()) file.delete();
Log.i("LOAD", root + fname);
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
Use this code this we help you to store images into a particular folder which is saved_images and that folder images show in gallery immediately.
private void SaveImage(Bitmap finalBitmap) {
String root = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES).toString();
File myDir = new File(root + "/saved_images");
myDir.mkdirs();
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Image-"+ n +".jpg";
File file = new File (myDir, fname);
if (file.exists ()) file.delete ();
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
// sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,
// Uri.parse("file://"+ Environment.getExternalStorageDirectory())));
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
// Tell the media scanner about the new file so that it is
// immediately available to the user.
MediaScannerConnection.scanFile(this, new String[]{file.toString()}, null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
Log.i("ExternalStorage", "Scanned " + path + ":");
Log.i("ExternalStorage", "-> uri=" + uri);
}
});
}
From Android Q there are changes in saving image to gallery.Thanks to #BaoLei, here is my answer in java if anybody needs it.
private void saveImage(Bitmap bitmap) {
if (android.os.Build.VERSION.SDK_INT >= 29) {
ContentValues values = contentValues();
values.put(MediaStore.Images.Media.RELATIVE_PATH, "Pictures/" + getString(R.string.app_name));
values.put(MediaStore.Images.Media.IS_PENDING, true);
Uri uri = this.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
if (uri != null) {
try {
saveImageToStream(bitmap, this.getContentResolver().openOutputStream(uri));
values.put(MediaStore.Images.Media.IS_PENDING, false);
this.getContentResolver().update(uri, values, null, null);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
} else {
File directory = new File(Environment.getExternalStorageDirectory().toString() + '/' + getString(R.string.app_name));
if (!directory.exists()) {
directory.mkdirs();
}
String fileName = System.currentTimeMillis() + ".png";
File file = new File(directory, fileName);
try {
saveImageToStream(bitmap, new FileOutputStream(file));
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.DATA, file.getAbsolutePath());
this.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
}
private ContentValues contentValues() {
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.MIME_TYPE, "image/png");
values.put(MediaStore.Images.Media.DATE_ADDED, System.currentTimeMillis() / 1000);

Here is a fully working solution in Kotlin:
fun saveToGallery(context: Context, bitmap: Bitmap, albumName: String) {
val filename = "${System.currentTimeMillis()}.png"
val write: (OutputStream) -> Boolean = {
bitmap.compress(Bitmap.CompressFormat.PNG, 100, it)
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
val contentValues = ContentValues().apply {
put(MediaStore.MediaColumns.DISPLAY_NAME, filename)
put(MediaStore.MediaColumns.MIME_TYPE, "image/png")
put(MediaStore.MediaColumns.RELATIVE_PATH, "${Environment.DIRECTORY_DCIM}/$albumName")
}
context.contentResolver.let {
it.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues)?.let { uri ->
it.openOutputStream(uri)?.let(write)
}
}
} else {
val imagesDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM).toString() + File.separator + albumName
val file = File(imagesDir)
if (!file.exists()) {
file.mkdir()
}
val image = File(imagesDir, filename)
write(FileOutputStream(image))
}
}
Do it in One Line
MediaStore.Images.Media.insertImage(applicationContext.getContentResolver(), IMAGE ,"nameofimage" , "description");
Now we have android10 and android11, so here is an updated version, that will work in all android devices.
Make sure you have the WRITE_EXTERNAL_STORAGE permission before calling this function.
private fun saveMediaToStorage(bitmap: Bitmap) {
val filename = "${System.currentTimeMillis()}.jpg"
var fos: OutputStream? = null
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
contentResolver?.also { resolver ->
val contentValues = ContentValues().apply {
put(MediaStore.MediaColumns.DISPLAY_NAME, filename)
put(MediaStore.MediaColumns.MIME_TYPE, "image/jpg")
put(MediaStore.MediaColumns.RELATIVE_PATH, Environment.DIRECTORY_PICTURES)
}
val imageUri: Uri? =
resolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues)
fos = imageUri?.let { resolver.openOutputStream(it) }
}
} else {
val imagesDir =
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)
val image = File(imagesDir, filename)
fos = FileOutputStream(image)
}
fos?.use {
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, it)
toast("Saved to Photos")
}
}
Its kotlin, and I think very straight forward and self explaining code. But still if you have a problem, comment below and I will explain.
Reference: Android Save Bitmap to Gallery Tutorial.
I'd like to add Java code based on #Bao Lei 's answer that I used in my app.
private void saveImage(Bitmap bitmap, Context context, String folderName) throws FileNotFoundException {
if (android.os.Build.VERSION.SDK_INT >= 29) {
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.RELATIVE_PATH, "Pictures/" + folderName);
values.put(MediaStore.Images.Media.IS_PENDING, true);
// RELATIVE_PATH and IS_PENDING are introduced in API 29.
Uri uri = context.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
if (uri != null) {
saveImageToStream(bitmap, context.getContentResolver().openOutputStream(uri));
values.put(MediaStore.Images.Media.IS_PENDING, false);
context.getContentResolver().update(uri, values, null, null);
}
} else {
dir = new File(getApplicationContext().getExternalFilesDir(Environment.DIRECTORY_PICTURES),"");
// getExternalStorageDirectory is deprecated in API 29
if (!dir.exists()) {
dir.mkdirs();
}
java.util.Date date = new java.util.Date();
imageFile = new File(dir.getAbsolutePath()
+ File.separator
+ new Timestamp(date.getTime()).toString()
+ "Image.jpg");
imageFile = new File(dir.getAbsolutePath()
+ File.separator
+ new Timestamp(date.getTime()).toString()
+ "Image.jpg");
saveImageToStream(bitmap, new FileOutputStream(imageFile));
if (imageFile.getAbsolutePath() != null) {
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.DATA, imageFile.getAbsolutePath());
// .DATA is deprecated in API 29
context.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
}
}
}
private ContentValues contentValues() {
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.MIME_TYPE, "image/png");
values.put(MediaStore.Images.Media.DATE_ADDED, System.currentTimeMillis() / 1000);
values.put(MediaStore.Images.Media.DATE_TAKEN, System.currentTimeMillis());
return values;
}
private void saveImageToStream(Bitmap bitmap, OutputStream outputStream) {
if (outputStream != null) {
try {
bitmap.compress(Bitmap.CompressFormat.PNG, 100, outputStream);
outputStream.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
This one worked fine in my app.
For Media Scanning, you can simply do
val intent = Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE)
intent.data = Uri.fromFile(path) // path must be of File type
context.sendBroadcast(intent)
