resultCode is always 0 and request is always -1, . Activity.onActivityResult();

I would like to add this to another list of questions about resultCode == 0 and requestCode == 0.

Here is the synopsis: NoteActivity calls NoteSettingsActivity using startActivityForResult().

I have searched the web and when I pressed back button when super.onBackPressed(), the resultCode == 0. Well after further researching, it seems it returns this code whenever the back button is pressed, but after botching that super.onBackPressed() call and just simply finish() the application the onActivityResult()'s resultCode is still equals to 0. It goes the same with requestCode.

Also, I tried manipulating the manifest file, I have done so many changes just to get this work but nothings works for me.

Here is the snippet. Note that I have reverted back to my previous commit so I have lost my recent modifications, but please take a look on the code I have wrote before I notice that the resultCode is always equals to 0 (ACTIVITY_CANCELED)

@Override
public void onNoteSettingsActivityCalled(Note note)
{
    Intent intent = new Intent(this, NoteSettingsActivity.class);
    intent.putExtra(NoteExtrasKey.EXTRA_NOTE_ID, note.getNoteID());

    startActivityForResult(intent, NoteRequest.REQUEST_UPDATE_SETTINGS);
}

Here is when the activity detected back press:

@Override
public void onBackPressed()
{   
    Log.i(NoteApplication.TAG, "NoteSettingsActivity.onBackPressed() has been called.");

    Intent intent = new Intent();
    intent.putExtra(NoteExtrasKey.EXTRA_NOTE_REMINDENABLED , mRemindEnabled);
    intent.putExtra(NoteExtrasKey.EXTRA_NOTE_REMINDEVERY   , mDaysSelected);
    intent.putExtra(NoteExtrasKey.EXTRA_NOTE_REMINDON      , String.valueOf(mRemindDateTime));
    intent.putExtra(NoteExtrasKey.EXTRA_NOTE_ID            , mTargetNoteID);

    if(getParent() != null)
        getParent().setResult(Activity.RESULT_OK, intent);
    else
        setResult(Activity.RESULT_OK, intent);

    super.onBackPressed();
}

Here's how NoteActivity received the resulting call.

    @Override
public void onActivityResult(int result, int request, Intent intent)
{
    super.onActivityResult(result, request, intent);

    Log.i(NoteApplication.TAG, "NoteActivity.onActivityResult() has been called.");
    Log.i(NoteApplication.TAG, "NoteActivity.onActivityResult() result = " + result + " request = " + request);

    if(result == Activity.RESULT_CANCELED)
        return;

    switch(request)
    {
        case NoteRequest.REQUEST_UPDATE_SETTINGS:

            if(intent == null) return;

            int noteID = intent.getIntExtra(NoteExtrasKey.EXTRA_NOTE_ID, -1);
            String remindOnString = intent.getStringExtra(NoteExtrasKey.EXTRA_NOTE_REMINDON);

            if(remindOnString != null && !remindOnString.equals(""))
                mRemindDateTime = Timestamp.valueOf(remindOnString);

            mHasSettingsEnabled = true;
            mRemindEnabled = intent.getBooleanExtra(NoteExtrasKey.EXTRA_NOTE_REMINDENABLED, false);
            mSelectedDays = intent.getIntegerArrayListExtra(NoteExtrasKey.EXTRA_NOTE_REMINDEVERY);

            if(noteID < 0)
            {
                Note note = mNoteDatabaseHelper.getNote(noteID);
                note.setRemindEnabled(mRemindEnabled);
                note.remindEvery(mSelectedDays);
                note.remindOn(mRemindDateTime);

                onNoteItemUpdated(note); 
            }

            Log.i(NoteApplication.TAG, "NoteActivity.onActivityResult() NoteRequest.REQUEST_UPDATE_SETTINGS called.");

            break;

        default:
            Log.i(NoteApplication.TAG, "NoteActivity.onActivityResult() : unknown request code = " + request);
            break;
    }
}

resultCode equals 0 and requestCode requals -1 when I ran this. I have checked the intent passed on this and it is not null.

Here are the questions very related to this question. None of them worked:

I am losing a lot of important hours working on my project just figuring out what makes the value for resultCode and requestCode lose the value I sent along the way.

Any help and guidance will be appreciated. Thank you very much!

What is onActivityResult?

onActivityResult is the callback you have on the first activity to grab the contacts you choose. Follow this answer to receive notifications.

How can we call fragment onActivityResult from activity?

To get the result in your fragment make sure you call startActivityForResult(intent,111); instead of getActivity(). startActivityForResult(intent,111); inside your fragment. @StErMi Make sure you call startActivityForResult() and not getActivity(). startActivityForResult() from your fragment.

What is purpose of startActivityForResult () function?

By the help of android startActivityForResult() method, we can send information from one activity to another and vice-versa. The android startActivityForResult method, requires a result from the second activity (activity to be invoked).

Is onActivityResult called before onResume?

You will receive this call immediately before onResume() when your activity is re-starting. Show activity on this post.

In my case, I got the resultCode == 0 error because of two reasons.

Firstly, I copied the method from a fragment instead of from another activity:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

A good way to prevent this from happening is to @Override your method so that you know you are overriding the default activity onActivityResult method signature.

Use the correct signature:

public void onActivityResult(int requestCode, int resultCode, Intent data) {

Secondly, I was doing this:

    super.onBackPressed();
    Intent intent = new Intent();
    intent.putExtra(getString(R.string.like_count), people.size());
    Log.e(TAG, people.size() +" people ");
    setResult(RESULT_OK, intent);
    finish();

The super.onBackPressed() set the resultCode before it was actually set hence it resulted in the 0.

A simple fix cause it to work properly:

    Intent intent = new Intent();
    intent.putExtra(getString(R.string.like_count), people.size());
    Log.e(TAG, people.size() +" people ");
    setResult(RESULT_OK, intent);
    super.onBackPressed();

The correct signature is

public void onActivityResult(int requestCode, int resultCode, Intent data) {

You have request and result mixed up.

The call to super.onBackPressed() is the one that will in the end set the result code and send it back to the calling activity. Replace that call with a call to finish() and you should get the result code that you are looking for.

Hope this helps!

Was facing the same issue while doing uninstalling an application from the device. It got resolved by putting: intentObject.putExtra(Intent.EXTRA_RETURN_RESULT, true); before you do startActivityForResult.
