Share and save Image of ImageView?

Question

I have app that has two buttons one for sharing a image and one for saving it to memory save button working perfectly but sharing button not working .

here is the save button :

public void exportImage () {
    if (this.mImageDrawableSet == false) {
        this.mSaveImageOnDisplay = true;
        return;
    }

    try {
        final Bitmap bitmap = getImageBitmap();
        if (bitmap == null) {
            Toast.makeText(getActivity(), "Something Went Wrong, Please Try Again!", Toast.LENGTH_SHORT).show();
            return;
        }

        final File dir = new File(Environment.getExternalStorageDirectory(), super.getResources().getString(R.string.config_external_storage_folder));

        if (!dir.exists()) {
            dir.mkdirs();
        }

        final File img = new File(dir, this.mNode.name + ".png");
        if (img.exists()) {
            img.delete();
        }

        final OutputStream outStream = new FileOutputStream(img);
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream);
        outStream.flush();
        outStream.close();

        super.getActivity().sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://" + dir.toString())));
        Toast.makeText(getActivity(), "Wallpaper Saved To, " + img.toString() + "!", Toast.LENGTH_LONG).show();
    } catch (Exception e) {
        Log.e(TAG, "", e);
        Toast.makeText(getActivity(), "Something Went Wrong, Please Try Again!", Toast.LENGTH_SHORT).show();
    }
}

and here is the share section :

public void shareimage () {
    if (this.mImageDrawableSet == false) {
        this.mApplyImageOnDisplay = true;
        return;
    }

    try {
        final Bitmap bitmap = getImageBitmap();
        if (bitmap == null) {
            Toast.makeText(getActivity(), "Something Went Wrong, Please Try Again!", Toast.LENGTH_SHORT).show();
            return;
        }       
        File root = Environment.getExternalStorageDirectory();
        File cachePath = new File(root.getAbsolutePath() + "/DCIM/Camera/image.jpg");

            cachePath.createNewFile();
            FileOutputStream ostream = new FileOutputStream(cachePath);
            bitmap.compress(CompressFormat.JPEG, 100, ostream);
            ostream.close();
            Intent share = new Intent(Intent.ACTION_SEND);
            share.setType("image/*");
            share.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(cachePath));
            startActivity(Intent.createChooser(share,"Share via"));
        } catch (Exception e) {
            e.printStackTrace();
            Toast.makeText(getActivity(), "Something Went Wrong, Please Try Again!", Toast.LENGTH_SHORT).show();
        }
    }

i found it in case anyone needed it final shareimage()

public void shareimage () {
    if (this.mImageDrawableSet == false) {
        this.mApplyImageOnDisplay = true;
        return;
    }

    try {
        final Bitmap bitmap = getImageBitmap();
        if (bitmap == null) {
            Toast.makeText(getActivity(), "Something Went Wrong, Please Try Again!1", Toast.LENGTH_SHORT).show();
            return;
        }       
        final File dir = new File(Environment.getExternalStorageDirectory(), super.getResources().getString(R.string.config_external_storage_folder));

        if (!dir.exists()) {
            dir.mkdirs();
        }

        final File img = new File(dir, this.mNode.name + ".png");
        if (img.exists()) {
            img.delete();
        }
        final OutputStream outStream = new FileOutputStream(img);
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream);
        outStream.flush();
        outStream.close();
            Intent share = new Intent(Intent.ACTION_SEND);
            share.setType("image/*");
            share.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(img));
            startActivity(Intent.createChooser(share,"Share via"));
        } catch (Exception e) {
            e.printStackTrace();
            Toast.makeText(getActivity(), "Something Went Wrong, Please Try Again!2", Toast.LENGTH_SHORT).show();
        }
    }

Answer 2

I guess that my code is smaller + since it uses openFileOutput() method from Context + MODE_WORLD_READABLE for temporary file it doesn't need any permissions:

    ImageView iv = (ImageView )adapter.getmCurrentView();
    String fileName = "image.jpg";
    iv.setDrawingCacheEnabled(true);
    Bitmap bitmap = iv.getDrawingCache();
    try
    {
        FileOutputStream ostream = getActivity().openFileOutput( fileName, Context.MODE_WORLD_READABLE);
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, ostream);
        ostream.close();
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }

    Intent share = new Intent(Intent.ACTION_SEND);
    share.setType("image/*");
    share.putExtra(Intent.EXTRA_SUBJECT, "Great photo from Poland!");
    share.putExtra(Intent.EXTRA_TEXT, "Hi,  I'm sharing with you this great picture!");
    share.putExtra(Intent.EXTRA_STREAM, Uri.fromFile( new File( getActivity().getFileStreamPath( fileName).getAbsolutePath())));
    startActivity(Intent.createChooser(share,"Share via"));
