How to open instagram's screen with a camera in android?

I tried to solve this case. However, the application crashes

Intent intent = new Intent("android.intent.action.MAIN");
intent.addCategory("android.intent.category.LAUNCHER");
intent.setComponent(new ComponentName("com.instagram.android", 
   "com.instagram.android.creation.activity.MediaCaptureActivity"));
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

startActivity(intent);
