Creating file from Uri
(6 answers)
Closed 4 years ago.
lets say I created an intent to pick an image from gallery or any other directory, I should get a uri from onActivityResult(), is it possible to copy the exact uri to a local file (intetnal storage).
onActivityResult(){
//get image uri
Uri uri=data.getData();
//create a file
File image_file=new File(path);
//now how to save uri to image_File???
}
Use this code to write in file
Ignore below code
File path = context.getFilesDir();
File file = new File(path, "myfile.txt");
FileOutputStream stream = new FileOutputStream(file);
Uri uri = ....
String uriStr = uri.toString();
try {
stream.write(uriStr.getBytes());
} finally {
stream.close();
}

Hi I am trying to make the images captured from my app inaccessible to the user. First I tried to save these images to internal storage which didnt work. Then I tried to hide them using "." infront of the folder name.I am not sure what the correct way to do this is. I also tried creating a file called .nomedia to bypass media scanner. I am very confused about the proper way to do this. Here's my code:
public String getImageUri(Context inContext, Bitmap inImage) {
/* *//* ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), inImage, ".title", null);
return Uri.parse(path);*//*
*/
File file = new File(Environment.getExternalStorageDirectory()
+ File.separator + "/.myFolder");
file.mkdirs();
File mFile = new File(Environment.getExternalStorageDirectory()
+ File.separator + "/.nomedia");
mFile.mkdirs();
FileOutputStream fOut = null;
try {
fOut = new FileOutputStream(file);
inImage.compress(Bitmap.CompressFormat.JPEG, 85, fOut);
fOut.flush();
fOut.close();
uri = MediaStore.Images.Media.insertImage(getContentResolver(), file.getAbsolutePath(), file.getName(), file.getName());
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return uri;
}
If I use file.mkdirs() I get filenotfoundexception. If i remove that line I get no errors but my uri is empty.
Does the above function return the file path as well? I need the file path and the uri later on. Any help is appreciated.
I guess you don't have to add another extension or something else just save them in external cache dir of your app and gallery app won't able to read your private directory until unless you notify about them.
so store your camera images here and no gallery app can detect it.
context.getExternalFilesDir(Environment.DIRECTORY_PICTURES);
sample code
public static File createPictureFile(Context context) throws IOException {
Locale locale = Locale.getDefault();
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", locale).format(new Date());
String fileName = "JPEG_" + timeStamp + "_";
// Store in normal camera directory
File storageDir = context.getExternalFilesDir(Environment.DIRECTORY_PICTURES);
return File.createTempFile(fileName, ".jpg", storageDir);
}
Save your image to internal storage instead. Other applications like MediaScanner or Gallery do not have permission to read from your own application memory. Sample code:
private String saveToInternalStorage(Bitmap bitmapImage){
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,"profile.jpg");
FileOutputStream fos = null;
try {
fos = new FileOutputStream(mypath);
// Use the compress method on the BitMap object to write image to the OutputStream
bitmapImage.compress(Bitmap.CompressFormat.PNG, 100, fos);
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return directory.getAbsolutePath();
}
Save the image with different extension.
For example: .jpg can be saved as .ttj.
Try this code. Set where you want to save the photo. Once you receive response on onActivityResult(), in the desired URI, you will get the photo.
public void captureImageFromCamera() {
fileUri = FileUtils.getInstance().getOutputMediaFile(null);
if(fileUri == null){
Utilities.displayToastMessage(ApplicationNekt.getContext(),
context.getString(R.string.unable_to_access_image));
return;
}
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(intent, TAKE_PICTURE);
}
Following function will give you desired path. Change it based on your project need.
public Uri getOutputMediaFile(String imageNameWithExtension) {
if (imageNameWithExtension == null)
imageNameWithExtension = "image_" + System.currentTimeMillis() + ".jpg";
String extPicDir = getExtDirPicturesPath();
if (!Utilities.isNullOrEmpty(extPicDir)) {
File mediaFile = new File(extPicDir, imageNameWithExtension);
return Uri.fromFile(mediaFile);
} else {
Log.d("tag", "getOutputMediaFile." +
"Empty external path received.");
return null;
}
}
public String getExtDirPicturesPath() {
File file = context.getExternalFilesDir(Environment.DIRECTORY_PICTURES);
if (file != null)
return file.getPath();
else
Log.d("", "getExtDirPicturesPath failed. Storage state: "
+ Environment.getExternalStorageState());
return null;
}
To get the resultant photo.
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode != Activity.RESULT_OK)
return;
switch (requestCode) {
case TAKE_PICTURE:
//fileuri variable has the path to your image.
break;
}
I am developing an Android app. In my app, I am creating image file from bitmap then save it to device. The process of creating image file from bitmap and save image to device is okay. The problem is I cannot find that created image in gallery. But the file really exist when I search it from file manager.
Here is my code:
File file = null;
try{
String fileName = String.valueOf(System.currentTimeMillis())+".jpeg";
file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), fileName);
if(file.exists()){
file.delete();
}
OutputStream os = new BufferedOutputStream(new FileOutputStream(file));
template.getBitmap().compress(Bitmap.CompressFormat.JPEG, 100, os);
os.close();
Toast.makeText(context,"Templated saved to your device",Toast.LENGTH_SHORT).show();
}
catch (Exception e) {
Toast.makeText(context,e.getMessage(),Toast.LENGTH_SHORT).show();
}
As you can see, I save it in the picture folder. I tried save it in download folder as well. File saved to device successfully but the problem is image is not displayed in Gallery. But exist in file manager. How can I make that image searchable in gallery?
try this:
File file = null;
try{
String fileName = String.valueOf(System.currentTimeMillis())+".jpeg";
file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), fileName);
if(file.exists())
{
file.delete();
}
OutputStream os = new BufferedOutputStream(new FileOutputStream(file));
template.getBitmap().compress(Bitmap.CompressFormat.JPEG, 100, os);
os.close();
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
Uri contentUri = Uri.fromFile(file);
mediaScanIntent.setData(contentUri);
sendBroadcast(mediaScanIntent);
Toast.makeText(context,"Templated saved to your device",Toast.LENGTH_SHORT).show();
}
catch (Exception e)
{
Toast.makeText(context,e.getMessage(),Toast.LENGTH_SHORT).show();
}
Use this code after saving file
try {
MediaScannerConnection.scanFile(context,
new String[] { mPath }, null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
}
});
} catch (Exception e) {
}

Android - Save images in an specific folder
(5 answers)
Closed 6 years ago.
i want to capture an image and save it into specific folder rather than in DCIM/Camera or Gallery...
want to save like: storage/sdcard0/DCIM/MyFolder.
Try this one it may be help you
public void takePicture(){
Intent imgIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
File imagesFolder = new File(Environment.getExternalStorageDirectory(), "ImagesApp");
imagesFolder.mkdirs(); // <----
File image = new File(imagesFolder, "temp.jpg");
Uri uriSavedImage = Uri.fromFile(image);
imgIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
startActivityForResult(imgIntent,IMAGE_CAPTURE_REQUEST_CODE);
}
You can use the following code
private String save(Bitmap bitmap)
{
File save_path = null;
if (android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED))
{
try
{
File sdCard = Environment.getExternalStorageDirectory();
File dir = new File(sdCard.getAbsolutePath() + "/DirName");
dir.mkdirs();
File file = new File(dir, "DirName_"+new SimpleDateFormat("yyyyMMdd_HHmmss").format(Calendar.getInstance().getTime())+ ".png");
save_path = file;
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100,baos);
FileOutputStream f = null;
f = new FileOutputStream(file);
MediaScannerConnection.scanFile(this, new String[]{file.getAbsolutePath()}, null, null);
if (f != null)
{
f.write(baos.toByteArray());
f.flush();
f.close();
}
}
catch (Exception e)
{
// TODO: handle exception
}
}
return String.valueOf(save_path);
}
Hope this will help you out...

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;
}
UPDATE 2: missing code added
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"/>
I try to save the image into WathsappIMG but when I go to image gallery android I don't see the image and the image there into the directory can be seen from ES File Explorer
OutputStream output;
// Find the SD Card path
File filepath = Environment.getExternalStorageDirectory();
// Create a new folder in SD Card
File dir = new File(filepath.getAbsolutePath()
+ "/WhatSappIMG/");
dir.mkdirs();
// Retrieve the image from the res folder
BitmapDrawable drawable = (BitmapDrawable) principal.getDrawable();
Bitmap bitmap1 = drawable.getBitmap();
// Create a name for the saved image
File file = new File(dir, "Wallpaper.jpg" );
try {
output = new FileOutputStream(file);
// Compress into png format image from 0% - 100%
bitmap1.compress(Bitmap.CompressFormat.JPEG, 100, output);
output.flush();
output.close();
}
catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
the gallery don't displaying (necessarily) files from external storage.
this is a common mistake.
the gallery displays images stored on the media store provider
you can use this method to store image file on media store provider:
public static void addImageToGallery(final String filePath, final Context context) {
ContentValues values = new ContentValues();
values.put(Images.Media.DATE_TAKEN, System.currentTimeMillis());
values.put(Images.Media.MIME_TYPE, "image/jpeg");
values.put(MediaStore.MediaColumns.DATA, filePath);
context.getContentResolver().insert(Images.Media.EXTERNAL_CONTENT_URI, values);
}
here is what you should enter, when you're about to save the picture in the Gallery
MediaStore.Images.Media.insertImage(getContentResolver(), yourBitmap, yourTitle , yourDescription);
That code will add the image at the end of the Gallery. so please, check your Gallery picture, to be sure
Try adding this:
MediaStore.Images.Media.insertImage(getContentResolver(), yourBitmap, yourTitle , yourDescription);
Fill in your details for yourBitmap, yourTitle, and yourDescription, or just leave it as "".
You need to add a MediaScannerConnection class to your function of saving the image to the gallery. This class scans for new files and folders in gallery connected with your app. Add the following class to scan the newly saved image files or new added image directory to the gallery or download Source Code
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);
}
});

For Xamarin fellows:
public static void SaveToTheGalley(this string filePath, Context context)
{
var values = new ContentValues();
values.Put(MediaStore.Images.Media.InterfaceConsts.DateTaken, Java.Lang.JavaSystem.CurrentTimeMillis());
values.Put(MediaStore.Images.Media.InterfaceConsts.MimeType, "image/jpeg");
values.Put(MediaStore.MediaColumns.Data, filePath);
context.ContentResolver.Insert(MediaStore.Images.Media.ExternalContentUri, values);
}
And don't forget about android.permission.WRITE_EXTERNAL_STORAGE permission.
As
MediaStore.MediaColumns.Data
and
MediaStore.Images.Media.insertImage
is deprecated now,
here is how I did it using bitmap
fun addImageToGallery(
fileName: String,
context: Context,
bitmap: Bitmap
) {
val values = ContentValues()
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
values.put(MediaStore.Images.Media.DATE_TAKEN, System.currentTimeMillis())
}
values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg")
values.put(MediaStore.Images.ImageColumns.DISPLAY_NAME, fileName)
values.put(MediaStore.Images.ImageColumns.TITLE, fileName)
val uri: Uri? = context.contentResolver.insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
values
)
uri?.let {
context.contentResolver.openOutputStream(uri)?.let { stream ->
val oStream =
BufferedOutputStream(stream)
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, oStream)
oStream.close()
}
}
}
You should change this piece of code-
try {
output = new FileOutputStream(file);
// Compress into png format image from 0% - 100%
bitmap1.compress(Bitmap.CompressFormat.JPEG, 100, output);
output.flush();
output.close();
String url = Images.Media.insertImage(getContentResolver(), bitmap1,
"Wallpaper.jpg", null);
}
catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Kindly refer this code worked for me:
public static boolean saveImageToGallery(Context context, Bitmap bmp) {
// First save the picture
String storePath = Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + "dearxy";
File appDir = new File(storePath);
if (!appDir.exists()) {
appDir.mkdir();
}
String fileName = System.currentTimeMillis() + ".jpg";
File file = new File(appDir, fileName);
try {
FileOutputStream fos = new FileOutputStream(file);
//Compress and save pictures by io stream
boolean isSuccess = bmp.compress(Bitmap.CompressFormat.JPEG, 60, fos);
fos.flush();
fos.close();
//Insert files into the system Gallery
//MediaStore.Images.Media.insertImage(context.getContentResolver(), file.getAbsolutePath(), fileName, null);
//Update the database by sending broadcast notifications after saving pictures
Uri uri = Uri.fromFile(file);
context.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, uri));
if (isSuccess) {
return true;
} else {
return false;
}
} catch (IOException e) {
e.printStackTrace();
}
return false;
}
Use the following code to make your image visible in the gallery.
public void saveImageToGallery(Context context, Uri path) {
// Create image from the Uri for storing it in the preferred location
Bitmap bmp = null;
ContentResolver contentResolver = getContentResolver();
try {
if(Build.VERSION.SDK_INT < 28) {
bmp = MediaStore.Images.Media.getBitmap(contentResolver, path);
} else {
ImageDecoder.Source source = ImageDecoder.createSource(contentResolver, path);
bmp = ImageDecoder.decodeBitmap(source);
}
} catch (Exception e) {
e.printStackTrace();
}
// Store image to internal storage/ImagePicker directory
String storePath = Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + "ImagePicker";
File appDir = new File(storePath);
if (!appDir.exists()) {
appDir.mkdir();
}
String fileName = System.currentTimeMillis() + ".jpg";
File file = new File(appDir, fileName);
try {
FileOutputStream fos = new FileOutputStream(file);
boolean isSuccess = bmp.compress(Bitmap.CompressFormat.JPEG, 60, fos);
fos.flush();
fos.close();
// Broadcast the image & make it visible in the gallery
Uri uri = Uri.fromFile(file);
context.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, uri));
if (isSuccess) {
Toast.makeText(context, "File saved to gallery", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(context, "Failed to save", Toast.LENGTH_SHORT).show();
}
} catch (IOException e) {
e.printStackTrace();
