Class variables set to onActivityResult are reset when the method returns

Question

I have an activity that allows the user to select a phone number. Naturally, I would like my class to remember the identifier of the selected contact, so I save it in the class field. However, when the onActivityResult method returns, my class variable is reset. Here is what I am trying to do:

Intent intent = new Intent(Intent.ACTION_PICK, People.CONTENT_URI); startActivityForResult(intent, PICK_CONTACT); ... public void onActivityResult(int reqCode, int resultCode, Intent intent){ super.onActivityResult(reqCode, resultCode, intent); switch(reqCode){ case(PICK_CONTACT): if(resultCode == Activity.RESULT_OK){ Uri contactData = intent.getData(); Cursor c = managedQuery(contactData, null, null, null, null); if(c.moveToFirst()){ contactName = c.getString(c.getColumnIndexOrThrow(People.NAME)); contactId = c.getInt(c.getColumnIndexOrThrow(People._ID)); break; 

When I set a breakpoint in this method, the values ​​for contactName and contactId will be what I expect, however as soon as the method returns, the values ​​will somehow get reset to default. It's clear that I'm missing something, but I'm not sure what I'm doing wrong or forgetting.

Thanks!

Not sure if you still need help. onActivityResult is called before onResume when your activity restarts. Make sure that you do not reset the values ​​of the variables in onResume.

You will receive this call immediately before onResume () when your activity restarts.
