Question

I have an activity that is resumed after a user picks a contact. Now before the user picks a contact onSavedInstanceState is called and i put a string in the Bundle. Now, After the user selects the contact and the results are returned. onRestoreInstanceState doesnt get called. only onResume() gets called. So how would i go about pulling my string back out of the bundle once the activity is resumed?

Answer 1

Lets say you have two Activities A and B, and Activity A starts Activity B. If you want to pass information from A to B, you can pass information from A to B with:

Intent i = new Intent(this. ActivityB.class);
i.putExtra("Key","Value");
startActivity(i);

Then in Activity B you can get the string with

String value = this.getIntent().getExtras().getString("keyName");

However, if you want to pass information from B to A you have to use a different method. Instead of using startActivity you need to use startActivityForResult. A description of this method is found here: How to return a result (startActivityForResult) from a TabHost Activity?
