Share Action provider to share image from imageView gives null pointer exception

I tried to share an image loaded into the imageview from glide following this guide, it gives me a null pointer exception. I've posted the code and stacktrace below, it

MainActivity.java

public class MainActivity extends AppCompatActivity {

    private EditText editText;
    private ShareActionProvider myShareActionProvider;
    //private Bitmap bitmap;
    private Uri uri;
    private Intent shareIntent;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final ImageView imageView = (ImageView) findViewById(R.id.imageView);

        String hi = "http://37n98a43dqtb4bua9n28nidp.wpengine.netdna-cdn.com/wp-content/uploads/2016/09/MyFriendPikachu.jpg";

        Glide
                .with(this)
                .load(hi)
                .listener(new RequestListener<String, GlideDrawable>() {
                    @Override
                    public boolean onException(Exception e, String model, Target<GlideDrawable> target, boolean isFirstResource) {
                        return false;
                    }

                    @Override
                    public boolean onResourceReady(GlideDrawable resource, String model, Target<GlideDrawable> target, boolean isFromMemoryCache, boolean isFirstResource) {
                        prepareShareIntent(((GlideBitmapDrawable) resource).getBitmap());
                        attachShareIntentAction();
                        return false;
                    }
                })
                .placeholder(R.drawable.ic_action_name)
                .error(R.drawable.ic_img_error)
                .centerCrop()
                .into(imageView);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        getMenuInflater().inflate(R.menu.img_menu, menu);

        MenuItem item = menu.findItem(R.id.action_share);

        myShareActionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(item);
        attachShareIntentAction();

        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {

        int id = item.getItemId();

        return super.onOptionsItemSelected(item);


    }

    public void prepareShareIntent(Bitmap drawableImage) {

        Uri bmpUri = getBitmapFromDrawable(drawableImage);

        shareIntent = new Intent();

        shareIntent.setAction(Intent.ACTION_SEND);

        shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);

        shareIntent.setType("image/*");

    }


    public void attachShareIntentAction() {

        if (myShareActionProvider != null && shareIntent != null)

            myShareActionProvider.setShareIntent(shareIntent);

    }


    public Uri getBitmapFromDrawable(Bitmap bmp) {


        Uri bmpUri = null;

        try {


            File file = new File(getExternalFilesDir(Environment.DIRECTORY_PICTURES), "images" + System.currentTimeMillis() + ".png");

            FileOutputStream out = new FileOutputStream(file);

            bmp.compress(Bitmap.CompressFormat.PNG, 90, out);

            out.close();


            bmpUri = FileProvider.getUriForFile(MainActivity.this, "com.example.imnobody.sampleprojectnetwork", file);  // use this version for API >= 24

            // **Note:** For API < 24, you may use bmpUri = Uri.fromFile(file);

        } catch (IOException e) {

            e.printStackTrace();

        }

        return bmpUri;

    }

}

Your <provider> has the following android:authorities value:

com.example.imnobody.sampleprojectnetwork.fileprovider

This is what you are providing to getUriForFile(), claiming that it is your provider's authority:

com.example.imnobody.sampleprojectnetwork

These are not the same, and they need to be.
