How to save image in android gallery

Closed 8 years ago.
I am saving Image from res/drawable to Gallery using InputStream and OutputStream. It works fine and save image. But issue is that It does not update Image in Gallery. If I check folder using ES File Explorer then I can see image there. I also checked ddms, It also update image there as soon as write code executes.It works fine if I save Server Image. How to prevent this issue ? I want to update Gallery as soon as Image save.I also tried MediaScanner to scan folder but no effect.
My Code:
Toast.makeText(context, "Downloading Image...\nPlease Wait.",
Toast.LENGTH_LONG).show();
File direct = new File(Environment.getExternalStorageDirectory()
+ "/Images");
if (!direct.exists()) {
direct.mkdirs();
}
DateFormat dateFormat = new SimpleDateFormat("ddMMyyyy-HHmmss");
Date date = new Date();
String CurrentDateTime = dateFormat.format(date);
InputStream input = null;
OutputStream output = null;
try {
input = context.getResources().openRawResource(
context.getResources().getIdentifier(
"#drawable/" + picName, "drawable",
context.getPackageName()));
output = new FileOutputStream(direct + "/" + "IMG-"
+ CurrentDateTime + ".jpg");
byte[] buf = new byte[1024];
int len;
while ((len = input.read(buf)) > 0) {
output.write(buf, 0, len);
}
MediaScannerConnection.scanFile(context,
new String[] { direct.toString() }, null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
Log.i("ExternalStorage", "Scanned " + path + ":");
Log.i("ExternalStorage", "-> uri=" + uri);
}
});
Toast.makeText(context, "Image Saved.", Toast.LENGTH_LONG).show();
} catch (Exception e) {
Log.e("Internal Image Save Error->", e.toString());
Toast.makeText(context,
"Couldn't Save Image.\nError:" + e.toString() + "",
Toast.LENGTH_LONG).show();
} finally {
try {
if (input != null) {
input.close();
}
if (output != null) {
output.close();
}
} catch (IOException ignored) {
Log.e("Internal Image Save Error->", ignored.toString());
Toast.makeText(
context,
"Couldn't Save Image.\nError:" + ignored.toString()
+ "", Toast.LENGTH_LONG).show();
}
}

you must broadcast external directory...
sendBroadcast(new Intent(
Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,
Uri.parse("file://" + Environment.getExternalStorageDirectory())));
if you create external folder in sdcard and then its not display in gallary then use below code.
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT) {
Runtime.getRuntime().exec(
"am broadcast -a android.intent.action.MEDIA_MOUNTED -d file://"
+ CommonVariable.abc_FOLDER);
} else {
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,
Uri.parse("file://" + CommonVariable.abc_FOLDER)));
}
other method for scanning.
Uri contentUri = Uri.fromFile(destFile);
Intent mediaScanIntent = new Intent(
Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
mediaScanIntent.setData(contentUri);
sendBroadcast(mediaScanIntent);
i hope its useful to you.

Image is not showing in gallery after save

Hi I am trying to save image in my gallery but the issue is that, not able to see in my gallery, following is my code can any one help?
public void OnClickSave(View view)
{
Bitmap bitmap =getBitmapFromView(idForSaveView);
try {
ContextWrapper wrapper = new ContextWrapper(context);
File file = wrapper.getDir("MilMilaImages",MODE_PRIVATE);
// Create a file to save the image
file = new File(file, "MilMila"+".jpg");
try{
OutputStream stream = null;
stream = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG,100,stream);
stream.flush();
stream.close();
}catch (IOException e) // Catch the exception
{
e.printStackTrace();
}
// Parse the gallery image url to uri
final Uri savedImageURI = Uri.parse(file.getAbsolutePath());
// Display the saved image to ImageView
System.out.println("HLL"+savedImageURI);
iv.setImageURI(savedImageURI);
MediaScannerConnection.scanFile(context, new String[] { file.getAbsolutePath()},
null,
new MediaScannerConnection.OnScanCompletedListener() {
#Override
public void onScanCompleted(String path, Uri uri) {
Log.i("ExternalStorage", "Scanned " + path + ":");
Log.i("ExternalStorage", "-> uri=" + uri);
}
});
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Intent mediaScanIntent = new Intent(
Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
Uri contentUri = Uri.fromFile(file);
mediaScanIntent.setData(contentUri);
context.sendBroadcast(mediaScanIntent);
} else {
context.sendBroadcast(new Intent(
Intent.ACTION_MEDIA_MOUNTED,
Uri.parse("file://"
+ Environment.getRootDirectory())));
}
// Display saved image uri to TextView
// Toast.makeText(context,"Saved Successfully",Toast.LENGTH_LONG).show();
} catch (Exception e) {
e.printStackTrace();
}
}

I have used this code and it works for me :
// show the image in the device gallery
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
val mediaScanIntent = Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE)
val contentUri = Uri.fromFile(compressFile) //out is your output file
mediaScanIntent.data = contentUri
this.sendBroadcast(mediaScanIntent)
} else {
sendBroadcast(Intent(Intent.ACTION_MEDIA_MOUNTED,
Uri.parse("file://" + Environment.getExternalStorageDirectory())))
}// // show the image in the device gallery

Image is not deleted but file.delete() returning true?

I am trying to delete image from device by using file.delete(). Delete method is being called and even it is returning true but when I open my gallery image is still there.
My image path is :
/data/user/0/com.myappname/app_myappname/20180413__164222_0.7680390806195996.png
Please have a look what i have tried.
1)
File file = new File(path);
if (file.exists()) {
file.delete();
}
2)
try {
File file = new File("file://" + path);
String getDirectoryPath = file.getParent(); // Only return path if physical file exist else return null
File fileNew = new File(getDirectoryPath);
fileNew.delete();
} catch (Exception e) {
}
3)
File file = mContext.getFilesDir(); // this will get you internal directory path
Log.d("BLA BLA", file.getAbsolutePath());
File newfile = new File(file.getAbsolutePath() + imagePath); // foo is the directory 2 create
newfile.delete();
4)
try
{
File sd = Environment.getExternalStorageDirectory();
File data = Environment.getDataDirectory();
if (sd.canWrite()) {
File fileName = new File(data, imagePath);
if (fileName.exists())
{
fileName.delete();
}
}
} catch (Exception e) {
}
I have applied almost every solution from stack overflow related to file.delete(). But nothing is working ? Any help or clue will be appreciated.
Edit:
I have refreshed the gallery when delete() returns true using this method but still image is present in app gallery.
Look at my code:
public void callBroadCast() {
if (Build.VERSION.SDK_INT >= 14) {
Log.e("-->", " >= 14");
MediaScannerConnection.scanFile(mContext, new String[]{Environment.getExternalStorageDirectory().toString()}, null, new MediaScannerConnection.OnScanCompletedListener() {
/*
* (non-Javadoc)
* #see android.media.MediaScannerConnection.OnScanCompletedListener#onScanCompleted(java.lang.String, android.net.Uri)
*/
public void onScanCompleted(String path, Uri uri) {
Log.e("ExternalStorage", "Scanned " + path + ":");
Log.e("ExternalStorage", "-> uri=" + uri);
}
});
} else {
Log.e("-->", " < 14");
mContext.sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,
Uri.parse("file://" + Environment.getExternalStorageDirectory())));
}
}

it says "no thumbnail" after the image is saved in to gallery- android bitmap

I have on Click method to save the image in to gallery . After i click "save" the folder is created in gallery , but when i go in to gallery it says " no thumbnail " ...
here is my code:
String root = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).toString();
File myDir = new File(root + "/PhotoEditor ");
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);
if (sb != null) {
sb.compress(Bitmap.CompressFormat.JPEG, 90, out);
}
out.flush();
out.close();
}
catch (Exception e) {
e.printStackTrace();
}
Toast.makeText(ShowPhotoActivity.this,"Your image is saved to gallery",Toast.LENGTH_LONG).show();
// Tell the media scanner about the new file so that it is
// immediately available to the user.
MediaScannerConnection.scanFile(ShowPhotoActivity.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);
}
});

Can you log "file.toString()" and see what you get? You might need to pass the absolute path: file.getAbsolutePath() as opposed to calling file.toString() but its hard to diagnose. Have you used a file manager app to confirm that the jpg really does exist after you've closed the stream?

How to save image in android gallery

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();
}
}

Save Images, Display in Gallery App

I'm currently working on an App that receives multiple images via socket. To save them, I wrote the following methods:
public static boolean saveTempImageToGallery(Context c) {
try {
FileInputStream fis = c.openFileInput(Settings.TEMP_PHOTO_STORAGE);
// create name of file: [date]-[time]-baby
final String tFilename = new SimpleDateFormat("dd-MM-yyyy_hh-mm-ss")
.format(new Date()) + ".png";
String state = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(state)) {
Log.d(TAG, "External storage available.");
// sd card available
File dir = getExternalStorageDir("Photos");
if (dir.mkdirs() || dir.isDirectory()) {
Log.i(TAG, "Directory: "+dir.getAbsolutePath());
File newImage = new File(dir, tFilename);
if (newImage.createNewFile() && newImage.isFile()) {
Log.i(TAG, "Saving image to "+newImage.getAbsolutePath());
final Bitmap bmp = BitmapFactory.decodeStream(fis);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
// compress image to png
bmp.compress(Bitmap.CompressFormat.PNG, 40, baos);
FileOutputStream fo = new FileOutputStream(newImage);
fo.write(baos.toByteArray());
fo.close();
Log.i(TAG, "Image saved!");
return true;
}
} else {
Log.d(TAG, "Could not create directory.");
}
} else {
Log.d(TAG, "External storage not available.");
}
} catch (Exception e) {
}
return false;
}
public static File getExternalStorageDir() {
File sdCard = Environment.getExternalStorageDirectory();
File dir = new File(sdCard.getAbsolutePath() + "/"
+ Settings.EXT_STORAGE_DIRECTORY);
return dir;
}
public static File getExternalStorageDir(String subdir) {
File sdCard = Environment.getExternalStorageDirectory();
File dir = new File(sdCard.getAbsolutePath() + "/"
+ Settings.EXT_STORAGE_DIRECTORY + "/" + subdir);
return dir;
}
After saving them, I'd like to offer the user the possibility to view them in the default gallery app. After reading some post, I adapted the following code:
MediaScannerConnectionClient mScanClient = new MediaScannerConnectionClient() {
#Override
public void onScanCompleted(String path, Uri uri) {
try {
Log.d("onScanCompleted", uri + "success");
if (uri != null) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(uri);
startActivity(intent);
}
} finally {
if (mScanCon != null)
mScanCon.disconnect();
mScanCon = null;
}
}
#Override
public void onMediaScannerConnected() {
Log.i(TAG, "Media Scan Connected.");
String[] files = Support.getExternalStorageDir("Photos")
.list();
Log.i(TAG,
Support.getExternalStorageDir("Photos").list().length
+ " elements in dir.");
if (files.length > 0) {
for (String cur : files) {
if (cur.equals(".") || cur.equals(".."))
continue;
Log.i(TAG, "Using "
+ cur
+ " to scan stuff. "
+ Support.getExternalStorageDir("Photos")
.getAbsolutePath() + "/" + cur);
Log.i(TAG, "Not using "
+ cur
+ " to scan stuff. "
+ Support.getExternalStorageDir("Photos")
.toString() + "/" + cur);
mScanCon.scanFile(
Support.getExternalStorageDir("Photos")
.getAbsolutePath() + "/" + cur,
"image/*");
break;
}
} else {
Toast.makeText(getApplicationContext(),
"No images available.", Toast.LENGTH_LONG)
.show();
}
}
};
if (mScanCon != null)
mScanCon.disconnect();
mScanCon = new MediaScannerConnection(getApplicationContext(),
mScanClient);
mScanCon.connect();
Weird thing: Seems like onMediaScannerConnected is never fired - anyone has an idea? I've been searching the web and stackoverflow for the last hour..
Thank you.

You really don't have to connect to the media scanner to start a scan, you can use this static method instead.
MediaScannerConnection.scanFile(context, new String[] {dir.getAbsolutePath()}, null, null);
edit:
Uri uri = Uri.parse(filePath);
Intent i = new Intent(Intent.ACTION_VIEW);
i.setDataAndType(uri, "image/*");
startActivity(i);
