AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setMessage("Pick Image from")
            .setPositiveButton("Camera", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    //camera intent
                    Intent cameraIntent = new Intent(ConversationActivity.this, CameraActivity.class);
                    cameraIntent.putExtra("EXTRA_CONTACT_JID", contact.getJid());
                    startActivity(cameraIntent);
                }
            })
            .setNegativeButton("Gallery", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    Intent intent = new Intent();
                    // Show only images, no videos or anything else
                    intent.setType("image/*");
                    intent.setAction(Intent.ACTION_GET_CONTENT);
                    // Always show the chooser (if there are multiple options available)
                    startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);
                }
            });
    AlertDialog alert = builder.create();
    alert.show();
