How to create separate private folder for captured images?

I am trying to create a separate folder for captured images using the code and below code is working fine for creating separate folder and images also saved in that folder
My problem is captured images also appear in gallery and I don't want to show them in my gallery, Can someone help me please what will I do for my requirement
code:
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, "New Picture");
values.put(MediaStore.Images.Media.DESCRIPTION, "From your Camera");
imageUri = getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent, Constants.CAMERA_REQUEST_CODE);
private void onCaptureImageResult(Intent data) {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageUri);
File compressedFile1 = Utilities.saveImage(this, bitmap);
}
public static File saveImage(Context context, Bitmap imgBitmap) {
File mediaFile = null;
try {
//Bitmap imgBitmap = (Bitmap) data.getExtras().get("data");
File sd = Environment.getExternalStorageDirectory();
File imageFolder = new File(sd.getAbsolutePath() + File.separator +
".FOSImages");
if (!imageFolder.isDirectory()) {
imageFolder.mkdirs();
}
mediaFile = new File(imageFolder + File.separator + "fos_" +
System.currentTimeMillis() + ".jpg");
FileOutputStream fileOutputStream = new FileOutputStream(mediaFile);
imgBitmap.compress(Bitmap.CompressFormat.JPEG, 90, fileOutputStream);
fileOutputStream.close();
return mediaFile;
} catch (Throwable throwable) {
throwable.printStackTrace();
}
return mediaFile;
}

It's appearing in Gallery because you are using getExternalStorageDirectory(), this returns a public path accessible by all apps. So one solution is to use a private external path context.getExternalFilesDir(Environment.DIRECTORY_PICTURES), folderName), the files saved here will not be accessible by MediaScanner and therefore not visible in the Gallery, although they will be deleted when your app is deleted.

Saving images in a folder

int count=1;
if(block=="other(from camera)")
{
final String dir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) + "/picFolder/";
File newdir = new File(dir);
newdir.mkdirs();
int TAKE_PHOTO_CODE = 0;
count++;
file = dir+count+".jpg";
File newfile = new File(file);
try
{newfile.createNewFile();}
catch (IOException e) {}
Uri outputFileUri = Uri.fromFile(newfile);
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(cameraIntent, TAKE_PHOTO_CODE);
This is a code for taking the picture and saving it to the gallery.and I want to use the images which are getting stored.But unfortunately everytime I close the app and reopen it, the pictures starts again from 2.jpeg.Is there a way such that the pictures are taken in continuation even after reopening the app.

How can i save the image taken from camera intent to be used as a profile image?

In my app the user can take an image from the camera and use as a profile picture. Everything works, except that when the user leaves the app and returns then the image isn't there anymore. So how can I save that image to stay there even when the user exits the app?
Code for camera intent:
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
And onActivityResult:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
getLayoutInflater().inflate(R.layout.custon_header,null);
ImageView profimg = (ImageView) findViewById(R.id.roundedimg);
profimg.setImageBitmap(photo);
Could someone please assist me with this?
Thanks

data.getExtras().get("data");
only returns the thumbnail of the image which would be on low quality. You have to specify on your camera intent a location where the image will be saved:
File outputFile = new File(Environment.getExternalStorageDirectory() +"/myOutput.jpg");
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(Intent.EXTRA_OUTPUT,outputFile.getAbsolutePath());
startActivityForResult(cameraIntent, CAMERA_REQUEST);
and on your activityResult, simply use the outputfile for your bitmap:
bitmap = BitmapFactory.decodeFile(outputFile.getAbsolutePath());

You can configure the intent to store the image, using EXTRA_OUTPUT like this:
Intent imageIntent = new Intent(
MediaStore.ACTION_IMAGE_CAPTURE);
File imageFolder = new File(Environment
.getExternalStorageDirectory(), "YourFolderName");
if (!imagesFolder.exists()) {
imagesFolder.mkdirs();
}
File imageFile = new File(imagesFolder, "user.jpg");
Uri uriSavedImage = Uri.fromFile(image);
imageIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
imageIntent.putExtra(MediaStore.EXTRA_SCREEN_ORIENTATION,
ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
activity.startActivityForResult(imageIntent, CAMERA_REQUEST);
So you have the path and can decode the file to bitmap.

You need to save that image in sd-card or phone memory so that it can be accessed when you open your app again. You are seeing that image as soon as you take the image because it is there in the memory and as soon as you leave the app, the memory is released.
private void SaveBitmapInDirectory(Bitmap bitmap, String fileName)
{
File direct = new File(Environment.getExternalStorageDirectory() + "/dirName");
if (!direct.exists())
{
File profilePic = new File("/sdcard/dirName/");
profilePic.mkdirs();
}
File file = new File(new File("/sdcard/dirName/"), fileName);
if (file.exists())
{
file.delete();
}
try
{
FileOutputStream out = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();
}
catch (Exception e)
{
e.printStackTrace();
}
}
And load the file from directory in onCreate function by calling the following function:
void loadProfilerImage(String fileName)
{
File file = new File(new File("/sdcard/dirName/"), fileName);
if (file.exists())
{
Bitmap myBitmap = BitmapFactory.decodeFile(file.getAbsolutePath());
ImageView.setImageBitmap(myBitmap);
}
}

Rewrite code android

I need help with my code that save image to device on android but images are not showing in gallery i tried a lot of different code but not working i need implement it to this code
public class SaveImage extends Activity {
public void saveImage(ImageView imageView) {
Drawable image = imageView.getDrawable();
if(image != null && image instanceof BitmapDrawable) {
BitmapDrawable drawable = (BitmapDrawable) image;
Bitmap bitmap = drawable.getBitmap();
File dir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "Picster");
dir.mkdirs();
Date now = new Date();
String timestamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.US).format(now);
String path = dir.getPath() + File.separator;
File file = new File(path + "IMG_" + timestamp + ".jpg");
try {
FileOutputStream stream = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
stream.flush();
stream.close();
galleryAddPic(file.toString());
} catch (Exception e) {
// TODO: handle exception
}
}
}
public void galleryAddPic(String file) {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(file);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
}
}
i call it in other activity like this
final ImageView image = (ImageView) findViewById(R.id.messageImageView);
Uri imageUri = getIntent().getData();
Picasso.with(this).load(imageUri.toString()).into(image);
final Button button = (Button) findViewById(R.id.button_id);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
SaveImage cls2= new SaveImage();
cls2.saveImage(image);
}
});
look on my updated code i add new void galleryAddpic and call it in TRY block it save pictures but still not show in gallery

You just have to add some lines of code to show that image in gallery with instant effect.
Add this code after your file has been created successfully.
Code :
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, uri));
Example :
private void galleryAddPic() {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(mCurrentPhotoPath);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
}
Request the media scanner to scan a file and add it to the media database.

Android Application quits after saving picture

Hi Guys My application quits just after the image is saved, I cannot see why, Please help?
This is the button pressed method, after the picture is taken I press save, The image gets saved where it needs to be saved but the application just quits after I press save, It does not say "Not Responding", it just quits
cam.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
leakerID = leakId.getText().toString();
String direc = "/e3softData/DCIM/";
String fileName = leakerID+".jpg";
// get the path to sdcard
File sdcard = Environment.getExternalStorageDirectory();
// to this path add a new directory path
File dir = new File(sdcard.getAbsolutePath() + direc);
// create this directory if not already created
dir.mkdir();
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
File file = new File(dir, fileName);
String f = file.toString();
Uri uriSavedImage = Uri.fromFile(new File(f));
intent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
startActivityForResult(intent, 0);
}
});

public void onClick(View view) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File dir = new File(Environment.getExternalStorageDirectory() + "/e3softData/DCIM/");
if (!dir.exists()) {
dir.mkdir();
}
String fileName = leakerID+".jpg";
output = new File(dir.getAbsolutePath(), fileName);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(output));
startActivityForResult(intent, 0);
}
