How to save image to pictures folder in android

I want to save image to Pictures folder in android. I do not have any external memory card attached.
Code:
String ImageDirectory = "QrCode";
#RequiresApi(api = Build.VERSION_CODES.N)
public void saveImage(Bitmap myBitmap, String busNumber, String imageName, EditText imagePath) {
String IMAGE_DIRECTORY = "QRCode";
try (ByteArrayOutputStream bytes = new ByteArrayOutputStream()) {
myBitmap.compress(Bitmap.CompressFormat.JPEG, 90, bytes);
File wallpaperDirectory = new File( Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES),IMAGE_DIRECTORY+ "/" + busNumber );
// have the object build the directory structure, if needed.
if (!wallpaperDirectory.exists()) {
Log.d("dirrrrrr", "" + wallpaperDirectory.mkdirs());
wallpaperDirectory.mkdirs();
}
try {
File f = new File(wallpaperDirectory, imageName + ".jpeg");
imagePath.setText("Sandeep");
f.createNewFile(); //give read write permission
imagePath.setText("Chintu");
FileOutputStream fo = new FileOutputStream(f);
fo.write(bytes.toByteArray());
MediaScannerConnection.scanFile(this,
new String[]{f.getPath()},
new String[]{"image/jpeg"}, null);
imagePath.setText("f.getAbsolutePath()");
fo.close();
Log.d("TAG", "File Saved::--->" + f.getAbsolutePath());
Toast.makeText(getBaseContext(), f.getAbsolutePath(), Toast.LENGTH_SHORT).show();
//return f.getAbsolutePath();
} catch (IOException e1) {
e1.printStackTrace();
//imagePath.setText("Pintu");
}
} catch (IOException e) {
e.printStackTrace();
}
}
imagePath.setText("Sandeep"); is executed. But imagePath.setText("Chintu"); is not executed. So, it throws exception at f.createNewFile(); catch block is executed and imagePath.setText("Pintu"); is executed
manifestfile:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

You are using wroing picture directory. The path of Picture directory:
File pictureDir= Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
File file = new File(pictureDir, "ImageName.jpg");

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,

if (extras != null) {
Bitmap photooutput = extras.getParcelable("data");
// Camera Output
if (pick == 1) {
viewImage.setImageBitmap(photooutput);
String path = Environment.getExternalStorageDirectory().toString();

How to save an image from ImageView?

have imagview want to save it to memory here is my code :
View content = findViewById(R.id.full_image_view);
content.setDrawingCacheEnabled(true);
Bitmap bitmap = content.getDrawingCache();
File root = Environment.getExternalStorageDirectory();
File cachePath = new File(root.getAbsolutePath() + "/DCIM/Camera/image.jpg");
try {
root.createNewFile();
FileOutputStream ostream = new FileOutputStream(root);
bitmap.compress(CompressFormat.JPEG, 100, ostream);
ostream.close();
} catch (Exception e) {
e.printStackTrace();
}
}
after saving nothing happens and no image is exist ?

Try this..
Change root.createNewFile(); to cachePath.createNewFile();
File root = Environment.getExternalStorageDirectory();
File cachePath = new File(root.getAbsolutePath() + "/DCIM/Camera/image.jpg");
try {
cachePath.createNewFile();
FileOutputStream ostream = new FileOutputStream(cachePath);
bitmap.compress(CompressFormat.JPEG, 100, ostream);
ostream.close();
} catch (Exception e) {
e.printStackTrace();
}
EDIT:
FileOutputStream ostream = new FileOutputStream(cachePath);

Use this function to save in SD card:
private void SaveIamge(Bitmap finalBitmap) {
String root = Environment.getExternalStorageDirectory().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);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
and add in manifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

1 - you need an appropriate permission in amnifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
2- out.flush() check the out is not null..
3 -
String file_path = Environment.getExternalStorageDirectory().getAbsolutePath() +
"/yourforlderName";
File dir = new File(file_path);
if(!dir.exists())
dir.mkdirs();
File file = new File(dir, "yourforlderName" + image + ".png");
FileOutputStream fOut = new FileOutputStream(file);
bmp.compress(Bitmap.CompressFormat.PNG, 85, fOut);
fOut.flush();
fOut.close();
if you don't create directory in your sdcard then how to store images in sdcard of specific location?
so please check this...i hope its useful to you.

To get bitmap from imageview:
imageview.buildDrawingCache();
Bitmap bm=imageview.getDrawingCache();
To save it in a file:
OutputStream fOut = null;
Uri outputFileUri;
try {
File root = new File(Environment.getExternalStorageDirectory()
+ File.separator + "folder_name" + File.separator);
root.mkdirs();
File sdImageMainDirectory = new File(root, "myPicName.jpg");
outputFileUri = Uri.fromFile(sdImageMainDirectory);
fOut = new FileOutputStream(sdImageMainDirectory);
} catch (Exception e) {
Toast.makeText(this, "Error occured. Please try again later.",
Toast.LENGTH_SHORT).show();
}
try {
bm.compress(Bitmap.CompressFormat.PNG, 100, fOut);
fOut.flush();
fOut.close();
} catch (Exception e) {
}
add in manifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

How about using following snippet ?
Drawable d = imageView.getBackground();
Bitmap bitmap = ((BitmapDrawable)d).getBitmap();
File file = new File(Environment.getExternalStorageDirectory(), "fileName.ext");
outStream = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, outStream);
outStream.flush();
outStream.close();

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!

Save Bitmap into File and return File having bitmap image

I have a problem to save Bitmaps into files.
My method is like this:
private File savebitmap(Bitmap bmp) {
String extStorageDirectory = Environment.getExternalStorageDirectory()
.toString();
OutputStream outStream = null;
File file = new File(bmp + ".png");
if (file.exists()) {
file.delete();
file = new File(extStorageDirectory, bmp + ".png");
Log.e("file exist", "" + file + ",Bitmap= " + bmp);
}
try {
outStream = new FileOutputStream(file);
bmp.compress(Bitmap.CompressFormat.PNG, 100, outStream);
outStream.flush();
outStream.close();
} catch (Exception e) {
e.printStackTrace();
}
Log.e("file", "" + file);
return file;
}
It gives me error of file.I am calling this method like this:
Drawable d = iv.getDrawable();
Bitmap bitmap = ((BitmapDrawable) d).getBitmap();
File file = savebitmap(bitmap);
Please help me...

I try to make some corrections on your code
I assume that you want to use filename instead of bitmap as parameter
private File savebitmap(String filename) {
String extStorageDirectory = Environment.getExternalStorageDirectory().toString();
OutputStream outStream = null;
File file = new File(filename + ".png");
if (file.exists()) {
file.delete();
file = new File(extStorageDirectory, filename + ".png");
Log.e("file exist", "" + file + ",Bitmap= " + filename);
}
try {
// make a new bitmap from your file
Bitmap bitmap = BitmapFactory.decodeFile(file.getName());
outStream = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, outStream);
outStream.flush();
outStream.close();
} catch (Exception e) {
e.printStackTrace();
}
Log.e("file", "" + file);
return file;
}

You can't write like this
File file = new File(bmp + ".png");
and this line is also wrong
file = new File(extStorageDirectory, bmp + ".png");
You have to give string value and not bitmap.
File file = new File(filename + ".png");

Change
File file = new File(bmp + ".png");
to
File file = new File(extStorageDirectory,"bmp.png");
like you did nearly the second time.
