Save image from ImageView to device gallery
I am trying to save image from ImageView to device gallery. I have tried this code
Editing the code:
URL url = new URL(getIntent().getStringExtra("imageURL"));
File f = new File(url.getPath());
addImageToGallery(f.getPath(), this);
public static void addImageToGallery(final String filePath, final Context context)
{
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.DATE_TAKEN, System.currentTimeMillis());
values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg");
values.put(MediaStore.MediaColumns.DATA, filePath);
context.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
}
but it requires a file path which I do not have, since I am loading the file from a url. How to save image from ImageView to gallery?
thank..

Plain:
use this code:
//to get the image from the ImageView (say iv)
BitmapDrawable draw = (BitmapDrawable) iv.getDrawable();
Bitmap bitmap = draw.getBitmap();
FileOutputStream outStream = null;
File sdCard = Environment.getExternalStorageDirectory();
File dir = new File(sdCard.getAbsolutePath() + "/YourFolderName");
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();
Also, to update the gallery and view the image:
Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
intent.setData(Uri.fromFile(file));
sendBroadcast(intent);
Also make sure storage permission is enabled in your application:
Go to "Device Settings"> "Device"> "Applications"> "Application Manager"> "Your Application"> "Permissions"> "Allow Access to Storage"!
Manifest permissions:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

ImageView iv = (ImageView)findViewById(R.id.your_image_view);
Then set the image and when you want to restore / save it
iv.buildDrawingCache();
Bitmap bmp = iv.getDrawingCache();
Then save as usual in the gallery
File storageLoc = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES); //context.getExternalFilesDir(null);
File file = new File(storageLoc, filename + ".jpg");
try{
FileOutputStream fos = new FileOutputStream(file);
bmp.compress(Bitmap.CompressFormat.JPEG, 100, fos);
fos.close();
scanFile(context, Uri.fromFile(file));
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
private static void scanFile(Context context, Uri imageUri){
Intent scanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
scanIntent.setData(imageUri);
context.sendBroadcast(scanIntent);
}
and of course, make sure your manifest has write permissions to external storage.
