Returning result from activity via Intent

I have two classes in my project: main and importer. Main starts Importer with startActivityForResult(), but how can Importer return its status to Main? Thanks :)

start Activity2 as startActivityForResult(Activity2,REQUEST_CODE)

after you finished your task in the next Activity2 

Intent output = new Intent();
output.putExtra("value1", somedata);
setResult(RESULT_OK, output);
finish();

and use onActivityResult() in Activity1

@Override
public void onActivityResult (int requestCode, int resultCode, Intent data) 
{
     if (requestCode == REQUEST_CODE && resultCode == RESULT_OK && data != null)
     val1 = data.getIntExtra("value1");
}

When Importer finishes its job, it has to call setResult(int, Intent) and the finish(). Main will receive the result in onActivityResult. I am assuming that both Importer and Main extend Activity.

Overrid this method inside Main:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
}

inside importer 

    Intent data = new Intent();
    data.putExtra("result", "i am the result");
    setResult(1000, data);
    finish();

then

onActivityResult will receive resultCode = 1000 and data != null

By calling setResult in Importer when you are ready to return to MainActivity. You can use setResult(int) to just send back a result code or setresult(int, Intent) to send back data.

Then use onActivityResult() in MainAcitivty to do what you need with the data

The Activity Docs have an example of doing this, although I don't believe it shows using setResult() but its pretty straightforward.
