Intent.putExtra(String,Bundle) vs Intent.putExtra(Bundle)

Question

This question may sound stupid but I wana know When do we put activity name in Intent.putExtra()? In one case we are putting extra only with bundle and in other

Answer 1

The approach is just the difference here. If you use a Bundle you can store almost all types in it:

Bundle mBundle = new Bundle();
mBundle.put(key, value);

and pass it to an activity

mIntent.putExtras(mBundle);

and in the other activity which recieves the info, just grab the content of the bundle like this:

   Bundle extras = getIntent().getExtras();

and grab each element in the bundle like this:

extras.getString("myKey")
