DO it this way... on Button Click check for SDK Version

 if (Build.VERSION.SDK_INT >= 23){
    // Here, thisActivity is the current activity
                        if (ContextCompat.checkSelfPermission(MainActivity.this,
                                Manifest.permission.READ_EXTERNAL_STORAGE)
                                != PackageManager.PERMISSION_GRANTED) {

                            // Should we show an explanation?
                            if (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this,
                                    Manifest.permission.READ_EXTERNAL_STORAGE)) {

                                // Show an expanation to the user *asynchronously* -- don't block
                                // this thread waiting for the user's response! After the user
                                // sees the explanation, try again to request the permission.

                            } else {

                                // No explanation needed, we can request the permission.

                                ActivityCompat.requestPermissions(MainActivity.this,
                                        new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
                                        MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE);

                                // MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE is an
                                // app-defined int constant. The callback method gets the
                                // result of the request.
                            }
                        }else{
                            ActivityCompat.requestPermissions(MainActivity.this,
                                    new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
                                    MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE);
                        }
                    }else {

                        Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
                        photoPickerIntent.setType("image/*");
                        startActivityForResult(photoPickerIntent, SELECT_PHOTO);
                    }

after that in Override method onRequestPermissionsResult write this code:

 case MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE: {
                // If request is cancelled, the result arrays are empty.
                if (grantResults.length > 0
                        && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                    // permission was granted, yay! Do the
                    // contacts-related task you need to do.
                    Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
                    photoPickerIntent.setType("image/*");
                    startActivityForResult(photoPickerIntent, SELECT_PHOTO);
                } else {

                    // permission denied, boo! Disable the
                    // functionality that depends on this permission.
                }
                return;
            }

After that

@Override
    protected void onActivityResult(int reqCode, int resultCode, Intent data) {
        super.onActivityResult(reqCode, resultCode, data);

        switch (reqCode) {
 case SELECT_PHOTO:
                if (resultCode == RESULT_OK) {
                    try {
                        final Uri imageUri = data.getData();
                        final InputStream imageStream = getContentResolver().openInputStream(imageUri);
                        final Bitmap selectedImage = BitmapFactory.decodeStream(imageStream);
                        contactimage.setImageBitmap(selectedImage);
                    } catch (FileNotFoundException e) {
                        e.printStackTrace();
                    }

                }
