What is a bundle in an Android

Bundle is generally used for passing data between various Activities of android. It depends on you what type of values you want to pass but bundle can hold all types of values and pass to the new activity.

You can use it like .....

Intent intent = new

Intent(getApplicationContext(),SecondActivity.class);

intent.putExtra("myKey",AnyValue);  

startActivity(intent);

Now you can get the passed values by...

Bundle extras = intent.getExtras(); 

String tmp = extras.getString("myKey");
