Bundle bundle = new Bundle();
bundle.putString("Key1", value1);
bundle.putString("Key2", value2);
in.putExtras(bundle); 
startActivity(in); 

ActivityTwo.java

Bundle bundle = getIntent().getExtras();
String valueReceived1 = bundle .getString("Key1");
String valueReceived2 = bundle .getString("Key2");

 

Code for passing array between activities in Android :

String[] array = new String[]{"Item1", "Item2", "item3", "Item4", "item5"};
Intent in = new Intent(this,ActivityTwo.class);

ActivityTwo.java

Bundle bundle = getIntent().getExtras();
String arrayReceived[] = bundle.getStringArray("MyArray");

 

Code for passing ArrayList between activities in Android :
