Passing data between activities on android is unfortunately, not as simple as passing in parameters. What we need to to do is tag these onto the intent. If the information we need to pass across is a simple object like a String or Integer, this is easy enough.
String strinParam = "String Parameter"; Integer intParam = 5; Intent i = new Intent(this, MyActivity.class); i.putExtra("uk.co.kraya.stringParam", stringParam); i.putExtra("uk.co.kraya.intParam", intParam); startActivity(i);
Passing in custom objects is a little more complicated. You could just mark the class as Serializable
and let Java take care of this. However, on the android, there is a serious performance hit that comes with using Serializable. The solution is to use Parcelable.
