How to save bitmap in custom gallery?

I have understood that I can create a folder in DCIM and if there is a file in it, the dir is displayed as an album name. I can create the dir just fine, in this case, I call the dir "ThoughtCast."
I try saving a PNG file, however, and it does not appear.
Here is my code:
public void savebitmap(Bitmap bmp) throws IOException {
String file_path =Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM) + File.separator + "ThoughtCast/";
File dir = new File(file_path);
if(!dir.exists())
dir.mkdirs();
File file = new File(dir, "sketchpad" + ".png");
FileOutputStream fOut = new FileOutputStream(file);
bmp.compress(Bitmap.CompressFormat.PNG, 85, fOut);
fOut.flush();
fOut.close();
}
Any help will be appreciated. Thanks

Try this it may help you (it's in kotlin)
I am currently do this task
private fun saveImage(bitmap: Bitmap) {
var outStream: FileOutputStream? = null
// Write to SD Card
try {
val dir = File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM) + File.separator + "ThoughtCast/")
dir.mkdirs()
val fileName = String.format("%s_%d.jpg", "Image", System.currentTimeMillis())
val outFile = File(dir, fileName)
outStream = FileOutputStream(outFile)
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream)
outStream.flush()
outStream.close()
Utils.showSnackBar(binding.rootView, getString(R.string.image_saved))
} catch (e: FileNotFoundException) {
Crashlytics.logException(e)
} catch (e: IOException) {
Crashlytics.logException(e)
} finally {
}
}

Try This Code Below. It may work for You.
private void saveImageStorage(Bitmap finalBitmap) {
String root = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DICM).toString();
File myDir = new File(root + "/" + <your folder if you want>);
if(!myDir.exists()){
myDir.mkdir();
}
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);
out.flush();
out.close();
}
catch (Exception e) {
e.printStackTrace();
}
// inform to 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);
}
});
}

convert the bitmap file (of a cuptured image) to a path file

the photo parameter is the bitmap and i checked it and it shows the cuptured image
how can i convert the bitmap to path so i will able to send as an attachment to mail
this is the code :
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.opencvhc);
ImgPhoto = (ImageView) findViewById(R.id.ImgPhoto);
Bundle extras = getIntent().getExtras();
if (extras != null) {
bm = (BitmapDataObject) getIntent().getSerializableExtra("photo"); //Obtaining data
bitmap = bm.getBip();
ImgPhoto.setImageBitmap(bitmap);
}
Checkmood = (Button) findViewById(R.id.Checkmood);
Check = (Button) findViewById(R.id.Check);
txtView = (TextView) findViewById(R.id.txt);
}
public void CheckClick(View view) throws IOException {
String file = MediaStore.Images.Media.insertImage(getContentResolver(), bitmap, "file", null);
//Uri screenshotUri = Uri.parse(file);
Toast.makeText(OpenCVhc.this, file, Toast.LENGTH_SHORT).show();
final Intent emailIntent1 = new Intent(android.content.Intent.ACTION_SEND);
emailIntent1.putExtra(Intent.EXTRA_EMAIL, new String[]{"comfplatform#gmail.com"});
emailIntent1.putExtra(Intent.EXTRA_SUBJECT, "Image processing picture");
emailIntent1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// emailIntent1.putExtra(Intent.EXTRA_STREAM, screenshotUri);
emailIntent1.putExtra(Intent.EXTRA_TEXT, "" +
"We checked your photo with the Ecg-Leads \n 1) : " +
"\n the image proccessing ___ ");
emailIntent1.setType("image/png");
try {
startActivity(Intent.createChooser(emailIntent1, "Send mail..."));
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(OpenCVhc.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
}
}
}

See this solution and don't forget to check for "WRITE_EXTERNAL_STORAGE" permission before writing to file.

Add permissions to your manifest
Remove space from file name (the image). With space you need decode the uri. You should paass the full path return file.getAbsolutePath(). You are just passing the file name.
In the case of file exists your not storing in the same path. You were not included the dictionary. extranlstoragepath+/temp_images/+the image.jpg try to log your file paths. And
File file = new File(mFolder.getAbsolutePath(), filename + ".jpg");
You have missed a / between two paramaters.
Wonderful blogpost about storing image

Android Studio save image into new directory [duplicate]

I need to save the pictures taken with my app in an specific folder. I've read many solutions to this problem but I couldn't make any of them work so I ask for help.
MainActivity.java
public void onClick(View v) {
Intent camera = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
//Folder is already created
String dirName = Environment.getExternalStorageDirectory().getPath()
+ "/MyAppFolder/MyApp" + n + ".png";
Uri uriSavedImage = Uri.fromFile(new File(dirName));
camera.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
startActivityForResult(camera, 1);
n++;
}
AndroidManifest.xml
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Go through the following code , its working fine for me.
private void createDirectoryAndSaveFile(Bitmap imageToSave, String fileName) {
File direct = new File(Environment.getExternalStorageDirectory() + "/DirName");
if (!direct.exists()) {
File wallpaperDirectory = new File("/sdcard/DirName/");
wallpaperDirectory.mkdirs();
}
File file = new File("/sdcard/DirName/", fileName);
if (file.exists()) {
file.delete();
}
try {
FileOutputStream out = new FileOutputStream(file);
imageToSave.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}

I have used mdDroid's code like this:
public void startCamera() {
// Create photo
newPhoto = new Photo();
newPhoto.setName(App.getPhotoName());
//Create folder !exist
String folderPath = Environment.getExternalStorageDirectory() + "/PestControl";
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);
}
}

Use Like this. It will work for you.
public void onClick(View v) {
Intent camera = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(camera, 1);
}
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch(requestCode) {
case 1:
if(resultCode == RESULT_OK) {
Uri selectedImage = imageReturnedIntent.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
//file path of captured image
filePath = cursor.getString(columnIndex);
//file path of captured image
File f = new File(filePath);
filename= f.getName();
Toast.makeText(getApplicationContext(), "Your Path:"+filePath, 2000).show();
Toast.makeText(getApplicationContext(), "Your Filename:"+filename, 2000).show();
cursor.close();
//Convert file path into bitmap image using below line.
// yourSelectedImage = BitmapFactory.decodeFile(filePath);
Toast.makeText(getApplicationContext(), "Your image"+yourSelectedImage, 2000).show();
//put bitmapimage in your imageview
//yourimgView.setImageBitmap(yourSelectedImage);
Savefile(filename,filePath);
}
}
}
public void Savefile(String name, String path) {
File direct = new File(Environment.getExternalStorageDirectory() + "/MyAppFolder/MyApp/");
File file = new File(Environment.getExternalStorageDirectory() + "/MyAppFolder/MyApp/"+n+".png");
if(!direct.exists()) {
direct.mkdir();
}
if (!file.exists()) {
try {
file.createNewFile();
FileChannel src = new FileInputStream(path).getChannel();
FileChannel dst = new FileOutputStream(file).getChannel();
dst.transferFrom(src, 0, src.size());
src.close();
dst.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
Hope this will help you. for reference to use camera intent.

Here You Go. I tried the above solution they save the image to gallery but the image is not visible , a 404 error is visible on the image , and i figured it out .
public void addToFav(String dirName, Bitmap bitmap) {
String resultPath = getExternalFilesDir(Environment.DIRECTORY_PICTURES)+
dirName + System.currentTimeMillis() + ".jpg";
Log.e("resultpath",resultPath);
new File(resultPath).getParentFile().mkdir();

}
if(fos != null){

}
}

I have found an easier code to do it.
This is the code for creating the image folder:
private File createImageFile(){
final String dir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) + "/App Folder/";
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "AppName_" + timeStamp;
String file = dir +imageFileName+ ".jpg" ;
File imageFile = new File(file);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = imageFile.getAbsolutePath();
return imageFile;
}
,And this is the code for launching the camera app and take the photo:
public void lunchCamera() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// Ensure that there's a camera activity to handle the intent
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = createImageFile();
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(this,
"com.ziad.sayit",
photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
}
