Share App Data Between Activities in Android

Android  Intent Tutorial: Sending data from One Activity to another Activity

We can send data while calling one activity from another activity using intent. All we have to do is add the data to Intent object using putExtra() method. The data is passed in key value pair. The value can be of types like int, float, long, string, etc.

Sending Data

Intent intent = new Intent(context, DestinationActivityName.class); intent.putExtra(Key, Value); startActivity(intent);

Here I am sending just one value, in the same way you can attach more values by using putExtra() method.

If the data sent is of type string then it can be fetched in following way.
