There is no standard way to do it. AFAIK Panorama, Photoshere are proprietary features of Gallery3d (provided by Google) package com.google.android.gallery3d. It's depends on firmware of the device.
in manifest file
in your activity
Intent res = new Intent();
String mPackage = "com.google.android.gallery3d";
String mClass = "com.google.android.apps.lightcycle.ProtectedPanoramaCaptureActivity";
res.setComponent(new ComponentName(mPackage,mClass));
startActivity(res);
