android share image from url

An adapted version of @eclass's answer which doesn't require use of an ImageView:

Use Picasso to load the url into a Bitmap

public void shareItem(String url) {    Picasso.with(getApplicationContext()).load(url).into(new Target() {        @Override public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {            Intent i = new Intent(Intent.ACTION_SEND);            i.setType("image/*");            i.putExtra(Intent.EXTRA_STREAM, getLocalBitmapUri(bitmap));            startActivity(Intent.createChooser(i, "Share Image"));        }        @Override public void onBitmapFailed(Drawable errorDrawable) { }        @Override public void onPrepareLoad(Drawable placeHolderDrawable) { }    });}

Convert Bitmap into Uri

public Uri getLocalBitmapUri(Bitmap bmp) {    Uri bmpUri = null;    try {        File file =  new File(getExternalFilesDir(Environment.DIRECTORY_PICTURES), "share_image_" + System.currentTimeMillis() + ".png");        FileOutputStream out = new FileOutputStream(file);        bmp.compress(Bitmap.CompressFormat.PNG, 90, out);        out.close();        bmpUri = Uri.fromFile(file);    } catch (IOException e) {        e.printStackTrace();    }    return bmpUri;}

I use these codes from this tutorial

        final ImageView imgview= (ImageView)findViewById(R.id.feedImage1);                Uri bmpUri = getLocalBitmapUri(imgview);                if (bmpUri != null) {                    // Construct a ShareIntent with link to image                    Intent shareIntent = new Intent();                    shareIntent.setAction(Intent.ACTION_SEND);                    shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);                    shareIntent.setType("image/*");                    // Launch sharing dialog for image                    startActivity(Intent.createChooser(shareIntent, "Share Image"));                    } else {                    // ...sharing failed, handle error                }

then add this to your activity

 public Uri getLocalBitmapUri(ImageView imageView) {    // Extract Bitmap from ImageView drawable    Drawable drawable = imageView.getDrawable();    Bitmap bmp = null;    if (drawable instanceof BitmapDrawable){       bmp = ((BitmapDrawable) imageView.getDrawable()).getBitmap();    } else {       return null;    }    // Store image to default external storage directory    Uri bmpUri = null;    try {        File file =  new File(Environment.getExternalStoragePublicDirectory(              Environment.DIRECTORY_DOWNLOADS), "share_image_" + System.currentTimeMillis() + ".png");        file.getParentFile().mkdirs();        FileOutputStream out = new FileOutputStream(file);        bmp.compress(Bitmap.CompressFormat.PNG, 90, out);        out.close();        bmpUri = Uri.fromFile(file);    } catch (IOException e) {        e.printStackTrace();    }    return bmpUri;}

then add your application manifest

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

You need to use a local file. Like this:

      Uri imageUri = Uri.parse("android.resource://your.package/drawable/fileName");      Intent intent = new Intent(Intent.ACTION_SEND);      intent.setType("image/png");      intent.putExtra(Intent.EXTRA_STREAM, imageUri);      startActivity(Intent.createChooser(intent , "Share"));

If your image is on remote server download it to the device first.
