I need to make images invisible from my gallery and i see other answers on stackoverflow but did not work for me .
this how i done that programmatically .
public void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode,data);
if(resultCode== Activity.RESULT_OK){
if(requestCode==REQUEST_CAMERA){
Uri selectedImageUri = data.getData();
if (null != selectedImageUri) {
// Get the path from the Uri
String path = getPathFromURI(selectedImageUri);
File file = new File(path);
Bitmap bmp = CommonMethod.compressImage(file, getContext());
Log.e(TAG, "onActivityResult --: "+ String.format("Size : %s", getReadableFileSize(file.length())));
mCustomerImage = CommonMethod.bitmapToByteArray(bmp);
imageTemplateStr = Base64.encodeToString(mCustomerImage, Base64.DEFAULT);
Log.e(TAG, "image: "+ imageTemplateStr );
//CommonMethod.SaveImage(bmp);
imageCustomer.setImageBitmap(bmp);
CommonMethod.SaveImage(bmp);
}
}else if(requestCode==SELECT_FILE){
Uri selectedImageUri = data.getData();
if (null != selectedImageUri) {
// Get the path from the Uri
String path = getPathFromURI(selectedImageUri);
File file = new File(path);
Bitmap bmp = CommonMethod.compressImage(file, getContext());
Log.e(TAG, "onActivityResult --: "+ String.format("Size : %s", getReadableFileSize(file.length())));
mCustomerImage = CommonMethod.bitmapToByteArray(bmp);
imageTemplateStr = Base64.encodeToString(mCustomerImage, Base64.DEFAULT);
//CommonMethod.SaveImage(bmp);
Log.e(TAG, "image: "+ imageTemplateStr );
imageCustomer.setImageBitmap(bmp);
CommonMethod.SaveImage(bmp);
}
}
SaveImage Method :
public static void SaveImage(Bitmap finalBitmap) {
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/safco_private_pics");
if (!myDir.exists()) {
myDir.mkdirs();
}
File newFile = new File(root,".nomedia");
try {
FileWriter writer = new FileWriter(newFile);
writer.flush();
writer.close();
} catch (IOException e) {
e.printStackTrace();
}
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();
}
}
getPathFromURI method
public String getPathFromURI(Uri contentUri) {
String res = null;
String[] proj = {MediaStore.Images.Media.DATA};
Cursor cursor = getActivity().getContentResolver().query(contentUri, proj, null, null, null);
if (cursor.moveToFirst()) {
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
res = cursor.getString(column_index);
}
cursor.close();
return res;
}
Now by that code images from gallery are not shown but images from Camera are visible in gallery and also .nomedia file not created.
Images are stored in my folder that i created and also in DCIM/Camera folder . I do not know why
What is wrong can anybody help me . ?
If you want to save the image for temporarily then you can use following code
File outputDir = context.getCacheDir(); // context should be the Activity pointer
File outputFile = File.createTempFile("prefix", "extension", outputDir);
Instead of
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/safco_private_pics");
For more details about cache dir read this: https://stackoverflow.com/a/6528104/7708305
But, If you want your file to be hidden and persisted on the permanent storage regardless of usage you can use following code.
File file = new File(root + "/.hidden_folder");
The dot(.) before the file/folder name makes it hidden.
let your image in hidden folder
//replace
File myDir = new File(root + "/safco_private_pics");
//with
File myDir = new File(root + "/.safco_private_pics");
put dot(.)before directory name it will create hidden directory and put your image in that directory

I am having an application containing different images using ImageView and ViewPager. I want to save the current image shown through ImageView in SD Storage. But it always saved in Phone Storage successfully.
I want to save the image in SD Card and also saved image not showing in Gallery Why? Kindly help me out in this issue:
public void SaveIamge() {
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/Cute_Baby_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);
int currentImagePos = viewPager.getCurrentItem();
Drawable drawable = viewPager.getResources().getDrawable(images[currentImagePos]);
Bitmap finalBitmap = ((BitmapDrawable) drawable).getBitmap();
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();
}
Toast.makeText(this, "Sucessfully Save Image", Toast.LENGTH_LONG).show();
}
Environment.getExternalDirectory() returns phone storage. To get location of SD card, check Find an external SD card location
To make the images appear in gallery, you should let the media scanner scan the file using MediaScannerConnection.scanFile()
Check Image, saved to sdcard, doesn't appear in Android's Gallery app
Create a function called getDirectory()
private static File getDirectory(String variableName, String... paths) {
String path = System.getenv(variableName);
if (!TextUtils.isEmpty(path)) {
if (path.contains(":")) {
for (String _path : path.split(":")) {
File file = new File(_path);
if (file.exists()) {
return file;
}
}
} else {
File file = new File(path);
if (file.exists()) {
return file;
}
}
}
if (paths != null && paths.length > 0) {
for (String _path : paths) {
File file = new File(_path);
if (file.exists()) {
return file;
}
}
}
//If any there is no SECONDARY STORAGE are detected return INTERENAL STORAGE
return Environment.getExternalStorageDirectory();
}
Change your code to
public void SaveIamge() {
String root = getDirectory("SECONDARY_STORAGE").getAbsolutePath();
File myDir = new File(root + "/Cute_Baby_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);
int currentImagePos = viewPager.getCurrentItem();
Drawable drawable = viewPager.getResources().getDrawable(images[currentImagePos]);
Bitmap finalBitmap = ((BitmapDrawable) drawable).getBitmap();
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();
}
Toast.makeText(this, "Sucessfully Save Image", Toast.LENGTH_LONG).show();
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://" + root)));
}
I have added a broadcast to notify the MediaScanner to re-scan the filesystem for new files. This will fix the problem of images are not showing in the gallery.

Hey I'm new to Android and I have been trying to make an app.
I am having trouble with part of saving the camera images into the newly created folder.
the problem is in to message variable i can create the file "newDir" if i use simple string "/folder1/folder2/",but if I use the "message" variable
I cant create it
// Your problem with message variable. Below is working code please go through it.
btnsave.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, 0);
}
});
//save you image when calling the onActivityResult method after capture image.
//When user click image vai camera then directly store to save_image folder.
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap mImageBitmap = (Bitmap) extras.get("data");
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);
mImageBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
// But the problem it is I want to record the photo in the path rot=root+message
// In another activity I have a qr-code scanner, every qr-code scanned corresponds to a path the content of every qr-code pass of the first activity to the second, the content is stored in the variable "message".
//Then i am obliged to use the variable "message" so that I draw to change the path to store my photo.
String message = getIntent().getExtras().getString("");
String root=Environment.getExternalStorageDirectory().toString();
String rot = root+message;
// String root = (Environment.getExternalStorageDirectory().getPath()+""/folder1/folder2/");
final File newDir = new File(rot + "/dossier_photos");
Here you did simple mistake with Path :
Environment.getExternalStorageDirectory().getPath() = /storage/emulated/0
Environment.getExternalStorageDirectory().getPath()+message = /storage/emulated/0message
So you got error,
here path should be like below:
String root = (Environment.getExternalStorageDirectory().getPath()+"/"+message);
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

//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();

//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 .

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);
}
}

I have created a program to capture the image and that is getting stored into sdcard/dcim/camera folder. Now I am trying to save the captured image in my own directory created in sdCard, say "/somedir".
I am able to make the directory programmatically but the image file is not getting stored in it.
Can anybody tell me where I am doing wrong here??
Here is the code....
File folder = new File(Environment.getExternalStorageDirectory() + "/abc");
Bitmap mybitmap1; //mybitmap1 contain image. So plz dont consider that I don't have image in mybitmap1;
if(!folder.exists())
{
success = folder.mkdir();
Log.i("Log", "folder created");
}
else
{
Log.i("Log", "Folder already present here!!");
}
String fname = date +".jpg";
file = new File( folder,fname);
if (file.exists ())
file.delete ();
capturedImageUri = Uri.fromFile(file);
FileOutputStream out;
byte[] byteArray = stream.toByteArray();
try {
out = new FileOutputStream(file);
mybitmap1.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();

You are settings the wrong file name for the file. Just use this method if you want to use time in the name of image file.
private Uri getImageUri() {
// Store image in dcim
String currentDateTimeString = getDateTime();
currentDateTimeString = removeChar(currentDateTimeString, '-');
currentDateTimeString = removeChar(currentDateTimeString, '_');
currentDateTimeString = removeChar(currentDateTimeString, ':');
currentDateTimeString = currentDateTimeString.trim();
File file = new File(Environment.getExternalStorageDirectory()
+ "/DCIM", currentDateTimeString + ".jpg");
Uri imgUri = Uri.fromFile(file);
return imgUri;
}
private final static String getDateTime() {
DateFormat df = new SimpleDateFormat("yyyy-MM-dd_hh:mm:ss");
df.setTimeZone(TimeZone.getTimeZone("PST"));
return df.format(new Date());
}
public static String removeChar(String s, char c) {
StringBuffer r = new StringBuffer(s.length());
r.setLength(s.length());
int current = 0;
for (int i = 0; i < s.length(); i++) {
char cur = s.charAt(i);
if (cur != c)
r.setCharAt(current++, cur);
}
return r.toString();
}
Hers is what you need to do:
instead of
File folder = new File(Environment.getExternalStorageDirectory() + "/abc");
do this
File folder = new File(Environment.getExternalStorageDirectory().getPath() + "/abc");
if(folder.exists()){
//save your file then
}
else{
folder.mkdirs();
//save your file then
}
Make sure you use the neccessary permissions in your Manifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
