How to save image in android gallery

But that answer is not working on my project. Please help me to find out a solution.

I designed two buttons in the application one for saving images and one for share images.

I have tried a code for download the images.but this code showing me nothing. 

imageView.setDrawingCacheEnabled(true);
Bitmap b = imageView.getDrawingCache();
MediaStore.Images.Media.insertImage(context.getContentResolver(), b ,"image", "image decsription");

Now I want to share the same image with the intent. I tried this code but it is showing me

unable to attach media file

my code is below..

private void createShareIntent(){
        Intent shareIntent=new Intent(Intent.ACTION_SEND);
        shareIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        shareIntent.setType("image/*");
        shareIntent.putExtra(Intent.EXTRA_STREAM,mImageUrl);
        shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        shareIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
        startActivity(Intent.createChooser(shareIntent,"Send "));
    }

Please help me to find a solution. Thanks in advance.

  • You have two things. Saving an image and sharing an image. It is unclear what goes wrong and what help you ask. A solution for what? Please edit your post. – greenapps Mar 13 '18 at 10:41
  • Didn't get it, which part is not working the saving part or the sharing one? Seems you have 2 different questions. For the first one, did you add the permissions for your app to access the external storage? – Eselfar Mar 13 '18 at 10:55
  • @Eselfar Both are not working. sharing part showing me error Unable to attach media file. – Anuj Mourya Mar 13 '18 at 10:59

Try This

//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();

Additionally, in order to refresh the gallery and to view the image there:

Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
intent.setData(Uri.fromFile(file));
sendBroadcast(intent);

Also make sure that your app has the storage permission enabled: Go to Device Settings>Device>Applications>Application Manager>"your app">Permissions>Enable Storage permission!

Manifest permissions:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
