In this code am going to illustrate the passing of string from one activity to another using intents.
Am going to create two activities one with an edit text and another one with a Textview then i will get the text entered in the textview and pass it to the textview in the other activity.
In this code there no modifications which need to be done on the manifest file and even the strings.xml file but for experienced programmers you can still use the strings xml instead of hard coding
