Image gets saved to wroung folder on sdcard Android

The code seems to work fine. The problem is that afterwards in my gallery I do not have an folder "myFolder" with my pics in it. Instead the pics get saved to storage/sdcard0/DCIM/camera and myFolder doesnt show up.
myDirectory = final static String myDirectory = "myFolder".
private void createDirectoryAndSaveFile(Bitmap imageToSave, String fileName) {
final File imageRoot = new File(Environment.getExternalStorageDirectory(), myDirectory);
if (!imageRoot.exists()) {
imageRoot.mkdirs();
}
File file = new File(imageRoot, fileName);
try {
if (!file.exists()) {
file.createNewFile();
}
FileOutputStream out = new FileOutputStream(file);
imageToSave.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}

Android app Image is not saving in specified Sd Card folder after Crop, Showing empty folder

I am capturing the image using camera in my android app.
then Cropping the image.
after Cropping saving the image in specified folder.
Folder is creating, But image is not saving in the folder.(Its Empty)
Help me to resolve it
code I have used,
link referred
if (extras != null) {
Bitmap photooutput = extras.getParcelable("data");
// Camera Output
if (pick == 1) {
viewImage.setImageBitmap(photooutput);
String path = Environment.getExternalStorageDirectory().toString();
File m_imgDirectory = new File(path + "/WallPaper/");
if (!m_imgDirectory.exists()) m_imgDirectory.mkdir();
FileOutputStream m_fOut = null;
File directory2 = new File(path);
directory2.delete();
String m_fileid = System.currentTimeMillis() + "";
directory2 = new File(path, "/Wall/" + m_fileid + ".png");
try
{
if (!directory2.exists()) directory2.createNewFile();
m_fOut = new FileOutputStream(directory2);
Bitmap m_bitmap = photooutput.copy(Bitmap.Config.ARGB_8888, true);
m_bitmap.compress(Bitmap.CompressFormat.PNG, 100, m_fOut);
m_fOut.flush();
m_fOut.close();
MediaStore.Images.Media.insertImage(getContentResolver(),
directory2.getAbsolutePath(), directory2.getName(), directory2.getName());
}
catch (Exception p_e)
{
}
}
}

When using Android KitKat and above, it is impossible for an app to save a file onto the SDCard.

UPDATE
Save an image to internal storage:
public static Uri saveImage(Bitmap bmp) {
Uri uri = null;
try {
String name = System.currentTimeMillis() + ".jpg";
//you can create a new file name "test.jpg" in sdcard folder.
File f = new File(getImagesDir() + File.separator + name);
f.createNewFile();
//write the bytes in file
FileOutputStream fo = new FileOutputStream(f);
fo.write(bitmapToByteArray(bmp));
// remember close de FileOutput
fo.close();
uri = Uri.parse("file://" + f.getPath());
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return uri;
}
public static String getImagesDir() {
String rootDir = Environment.getExternalStorageDirectory().toString();
rootDir = rootDir + "/MyApp/Media/Images";
// Create directory if not existed
File dir = new File(rootDir);
if (!dir.exists()) {
dir.mkdir();
}
return dir.getPath();
}
public static byte[] bitmapToByteArray(Bitmap bmp) {
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
return byteArray;

Add the following permissions to your AndroidManifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

android save images to internal storage

I'm having problems implementing this code Saving and Reading Bitmaps/Images from Internal memory in Android
to save and retrieve the image that I want, here is my code:
ContextWrapper cw = new ContextWrapper(getApplicationContext());
// path to /data/data/yourapp/app_data/imageDir
File directory = cw.getDir("imageDir", Context.MODE_PRIVATE);
// Create imageDir
File mypath=new File(directory, + name + "profile.jpg");
FileOutputStream fos = null;
try {
fos = new FileOutputStream(mypath);
// Use the compress method on the BitMap object to write image to the OutputStream
myBitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);
fos.close();
} catch (Exception e) {
e.printStackTrace();
}
and to retrieve(I don't know if I'm doing wrong)
#Override
protected void onResume()
{
super.onResume();
try {
File f = new File("imageDir/" + rowID, "profile.jpg");
Bitmap b = BitmapFactory.decodeStream(new FileInputStream(f));
image = (ImageView) findViewById(R.id.imageView2);
image.setImageBitmap(b);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
and nothing happens so what should I change??

To Save your bitmap in sdcard use the following code
Store Image
private void storeImage(Bitmap image) {
File pictureFile = getOutputMediaFile();
if (pictureFile == null) {
Log.d(TAG,
"Error creating media file, check storage permissions: ");// e.getMessage());
return;
}
try {
FileOutputStream fos = new FileOutputStream(pictureFile);
image.compress(Bitmap.CompressFormat.PNG, 90, fos);
fos.close();
} catch (FileNotFoundException e) {
Log.d(TAG, "File not found: " + e.getMessage());
} catch (IOException e) {
Log.d(TAG, "Error accessing file: " + e.getMessage());
}
}
To Get the Path for Image Storage
/** Create a File for saving an image or video */
private File getOutputMediaFile(){
// To be safe, you should check that the SDCard is mounted
// using Environment.getExternalStorageState() before doing this.
File mediaStorageDir = new File(Environment.getExternalStorageDirectory()
+ "/Android/data/"
+ getApplicationContext().getPackageName()
+ "/Files");
// This location works best if you want the created images to be shared
// between applications and persist after your app has been uninstalled.
// Create the storage directory if it does not exist
if (! mediaStorageDir.exists()){
if (! mediaStorageDir.mkdirs()){
return null;
}
}
// Create a media file name
String timeStamp = new SimpleDateFormat("ddMMyyyy_HHmm").format(new Date());
File mediaFile;
String mImageName="MI_"+ timeStamp +".jpg";
mediaFile = new File(mediaStorageDir.getPath() + File.separator + mImageName);
return mediaFile;
}

I think Faibo's answer should be accepted, as the code example is correct, well written and should solve your specific problem, without a hitch.
In case his solution doesn't meet your needs, I want to suggest an alternative approach.
It's very simple to store image data as a blob in a SQLite DB and retrieve as a byte array. Encoding and decoding takes just a few lines of code (for each), works like a charm and is surprisingly efficient.
I'll provide a code example upon request.
Good luck!

Note that you are saving the pick as name + profile.jpg under imageDir directory and you're trying to retrieve as profile.jpg under imageDir/[rowID] directory check that.

I got it working!
First make sure that your app has the storage permission enabled:
Go to Device Settings>Device>Applications>Application Manager>"your app">Permissions>Enable Storage permission!
Permissions in manifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
So, if you want to create your own directory in your File Storage you can use somethibng like:
FileOutputStream outStream = null;
File sdCard = Environment.getExternalStorageDirectory();
File dir = new File(sdCard.getAbsolutePath() + "/camtest");
dir.mkdirs();
String fileName = String.format("%d.jpg", System.currentTimeMillis());
File outFile = new File(dir, fileName);
outStream = new FileOutputStream(outFile);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream);
outStream.flush();
outStream.close();
refreshGallery(outFile);
Else, if you want to create a sub directory in your default device DCIM folder and then want to view your image in a separate folder in gallery:
FileOutputStream fos= null;
File file = getDisc();
if(!file.exists() && !file.mkdirs()) {
//Toast.makeText(this, "Can't create directory to store image", Toast.LENGTH_LONG).show();
//return;
print("file not created");
return;
}
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyymmsshhmmss");
String date = simpleDateFormat.format(new Date());
String name = "FileName"+date+".jpg";
String file_name = file.getAbsolutePath()+"/"+name;
File new_file = new File(file_name);
print("new_file created");
try {
fos= new FileOutputStream(new_file);
Bitmap bitmap = viewToBitmap(iv, iv.getWidth(), iv.getHeight() );
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);
Toast.makeText(this, "Save success", Toast.LENGTH_LONG).show();
fos.flush();
fos.close();
} catch (FileNotFoundException e) {
print("FNF");
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
refreshGallery(new_file);
Helper functions:
public void refreshGallery(File file){
Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
intent.setData(Uri.fromFile(file));
sendBroadcast(intent);
}
private File getDisc(){
String t= getCurrentDateAndTime();
File file = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
return new File(file, "ImageDemo");
}
private String getCurrentDateAndTime() {
Calendar c = Calendar.getInstance();
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd-HH-mm-ss");
String formattedDate = df.format(c.getTime());
return formattedDate;
public static Bitmap viewToBitmap(View view, int width, int height) {
Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
view.draw(canvas);
return bitmap;
}
Hope this helps!

android: saving files to specific folder for later retrieval

I am working on a drawing part, and have written the following code to save the image to the designated camera folder. However, I would rather like to create a new folder using the app name and save the image to the folder. How could that be made?
I would also like to later on retrieve the image files from that specific folder too.
Thanks!
Current code:
String fileName = "ABC";
// create a ContentValues and configure new image's data
ContentValues values = new ContentValues();
values.put(Images.Media.TITLE, fileName);
values.put(Images.Media.DATE_ADDED, System.currentTimeMillis());
values.put(Images.Media.MIME_TYPE, "image/jpg");
// get a Uri for the location to save the file
Uri uri = getContext().getContentResolver().insert(Images.Media.EXTERNAL_CONTENT_URI, values);
try
{
OutputStream outStream = getContext().getContentResolver().openOutputStream(uri);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream);
outStream.flush(); // empty the buffer
outStream.close(); // close the stream

Try this it might help you.
public void saveImageToExternalStorage(Bitmap image) {
String fullPath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/directoryName";
try
{
File dir = new File(fullPath);
if (!dir.exists()) {
dir.mkdirs();
}
OutputStream fOut = null;
File file = new File(fullPath, "image.png");
if(file.exists())
file.delete();
file.createNewFile();
fOut = new FileOutputStream(file);
// 100 means no compression, the lower you go, the stronger the compression
image.compress(Bitmap.CompressFormat.PNG, 100, fOut);
fOut.flush();
fOut.close();
}
catch (Exception e)
{
Log.e("saveToExternalStorage()", e.getMessage());
}
}

This Method works after so many try.
private String getFilename() {
String filepath = Environment.getExternalStorageDirectory().getPath();
File file = new File(filepath,AUDIO_RECORDER_FOLDER);
if(!file.exists()){
file.mkdirs();
}
return (file.getAbsolutePath() + "/" + System.currentTimeMillis() + ".mp3");
}

Save Bitmap to SD Card

I have a Bitmap image which I have to store in a folder in the SD Card, my code is shown below. It creates the folder and file as expected, but the image is not stored into the file, it remains an empty file... Can anyone tell me what's wrong?
Bitmap merged = Bitmap.createBitmap(mDragLayer.getChildAt(0).getWidth(), mDragLayer.getChildAt(0).getHeight(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(merged);
// save to folder in sd card
try {
File imagesFolder = new File(Environment.getExternalStorageDirectory(), "folder");
if(!imagesFolder.exists())
imagesFolder.mkdirs();
int imageNum;
if(imagesFolder.list()==null)
imageNum = 1;
else
imageNum = imagesFolder.list().length + 1;
String fileName = "file_" + String.valueOf(imageNum) + ".jpg";
File output = new File(imagesFolder, fileName);
while(output.exists()){
imageNum++;
fileName = "file_" + String.valueOf(imageNum) + ".jpg";
output = new File(imagesFolder, fileName);
}
OutputStream fOut = new FileOutputStream(output);
merged.compress(Bitmap.CompressFormat.JPEG, 100, fOut);
fOut.flush();
fOut.close();
Toast.makeText(getApplicationContext(), "Saved", Toast.LENGTH_SHORT).show();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}

First add permission to AndroidManifest.xml
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
Then write down in Java File as below.
String extr = Environment.getExternalStorageDirectory().toString();
File mFolder = new File(extr + "/MyApp");
if (!mFolder.exists()) {
mFolder.mkdir();
}
String strF = mFolder.getAbsolutePath();
File mSubFolder = new File(strF + "/MyApp-SubFolder");
if (!mSubFolder.exists()) {
mSubFolder.mkdir();
}
String s = "myfile.png";
f = new File(mSubFolder.getAbsolutePath(),s);
UPDATED
String strMyImagePath = f.getAbsolutePath();
FileOutputStream fos = null;
try {
fos = new FileOutputStream(f);
bitmap.compress(Bitmap.CompressFormat.PNG,70, fos);
fos.flush();
fos.close();
// MediaStore.Images.Media.insertImage(getContentResolver(), b, "Screen", "screen");
}catch (FileNotFoundException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}

Don't make it difficult with complex code its really very simple please Try below code.
Create first dir in your sd card :
public static String strpath = android.os.Environment.getExternalStorageDirectory().toString();
public static String dirName = "DIR_NAME";
File makeDirectory = new File(strpath+"/"+dirName);
makeDirectory.mkdir();
Then you should make two String Var like below :
String filename = "yourImageName".jpg";
String dirpath =strpath + "/"+dirName + "/";
Make File Variable :
File storagePath = new File(dirpath);
File myImage = new File(storagePath, filename);
outStream = new FileOutputStream(myImage);
outStream.write(data);
outStream.close();
Hope this may helpful to you.

you just need a bitmap
and you have to pass a path to store the image
Bitmap b = pagesView.getDrawingCache();
b.compress(CompressFormat.JPEG, 100, new FileOutputStream(Environment.getExternalStorageDirectory() + "/NameOfFile.jpg"));
and you have to add permission in Manifest file..
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
