Failure Delivering Results with HashMap between 2 activities

Question

Background:

• There are two activities
• 1x (MainActivity), 1x (SubActivity - Activity with a ListView)
• Main Activity extends FragmentActivity and the Infos will be used in a Fragment
• SubActivity will open when a MenuItem of MainActivity will be clicked.
• Using a HashMap for the ListView

My Goal:

• The HashMap values of the clicked Item should be send back to the MainActivity and SubActivity (with the ListView) should be closed.

Problem:

java.lang.RunTimeException: Failure delivering results ResultInfo{who=null, request=1, 
result=0, data=Intent { (has extras) }} to activity.

I think I made a huge mistake but I couldn't solve it.

switch case from onOptionsItemSelected and onActivityResult are in the MainActivity:

• PICKED has the value 1;

  switch (item.getItemId()) {

  case R.id.icon:
      Intent myIntent = new Intent(MainActivity.this, HeroListActivity.class);
      MainActivity.this.startActivityForResult(myIntent, PICKED);
      return true;
  default:
      return super.onOptionsItemSelected(item);
  } 
  
  
  
  protected void onActivityResult(int requestCode, int resultCode, Intent data){
          super.onActivityResult(requestCode, resultCode, data);
          if (requestCode == 1) {
              Intent intent = getIntent();
              HashMap<String, String> aList = (HashMap<String, String>)intent.getSerializableExtra("map");
              Log.d("HashMap", aList.get("Name"));
          }
  

  }

onItemClick in the SubActivity with the ListView:

• onItemClick is working and I get the correct data from the HashMap when I use Log.d.

  HashMap<String, String> o = (HashMap<String, String>) adapter.getItemAtPosition(position);
  Log.d("onItemClick", ""+o);
  
  Intent intent = new Intent();
  
  intent.putExtra("map", o);
  setResult(RESULTS_OK, intent);
  finish();

I hope someone can help me and thanks in advance.

Answer 1

You should replace this line in your onActivityResult() method

 Intent intent = getIntent();

with this:

 Intent intent = data;

data is the name of a parameter you are passing in - that's where your extras reside. getIntent() call returns a null intent in this instance.
