How to use it from inside Fragment? about materialfilepicker

[dimorinny]

You should use [fragment's startActivityForResult](https://developer.android.com/reference/android/app/Fragment.html#startActivityForResult%28android.content.Intent, int%29) and handle response in [fragment's onActivityResult](https://developer.android.com/reference/android/app/Fragment.html#onActivityResult%28int, int, android.content.Intent%29) method.

Still, problem may occur if you use nested fragment API. Click here for more information.

Thank you for getting back to me. Before posting the issue, I had gone through similar questions on StackOverflow including the one you shared.
Based on those, this is what I was able to do so far -

(I) In my MainActivity, I have onActivityResult call as follows -

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

        Log.d(TAG, "onActivityResult triggered from Activity");
        if (requestCode == 1 && resultCode == RESULT_OK) {
            String filePath = data.getStringExtra(FilePickerActivity.RESULT_FILE_PATH);
            Log.d(TAG, "filePath (from Activity) => " + filePath);
            SettingsFragment.textDemo.setText(filePath);
        }
    }

(II) In SettingsFragment, declared the TextView as public static, because eventually, I need the Result inside that TextView only.
public static TextView textDemo;

(III) In SettingsFragment, I tried to call onActivityResult as follows -

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        Log.d(TAG, "onActivityResult triggered (from Fragment)");
        if (requestCode == 1 && resultCode == Activity.RESULT_OK) {
            String filePath = data.getStringExtra(FilePickerActivity.RESULT_FILE_PATH);
            Log.d(TAG, "filePath (from Fragment) => " + filePath);
            textDemo.setText(filePath);
        }
    }

From the logs, I found that no matter, how I modify (or shuffle) these codes, startActivityForResult always triggers onActivityResult from the Activity only, Never from the fragment.
As evident, by this method, I can get the output I wanted, but this does not appear to be the best/ideal way to do this. I have to be extra careful that this part of code never gets called when SettingsFragment is Not opened, as then, it would result in throwing up error due to using TextView textDemo of SettingsFragment.

P.S. -

1. In the Stackoverflow link you provided, one suggestion was to use this in onActivityResult of the Fragment. But where can I use that?
2. Few of the answers suggested that this problem has been fixed in Android Support Library 23.2+, and I am using Android Support Library 23.4. So it should have been fixed. So is this the normal behaviour / method to call onActivityResult from Fragment?

How should I do this?
Thank you.

Hi. The problem may be in incorrect call of startActivityForResult method. In this case you have to call startActivityForResult method of [Fragment](https://developer.android.com/reference/android/app/Fragment.html#startActivityForResult%28android.content.Intent, int%29) class, not method of Activity class: getActivity().startActivityForResult(...) - wrong.

Also problem might occur if you are using MaterialFilePicker builder class (with withActivity method). Starting activities from Fragment's using our builder class haven't supported yet. You should manually create Intent and start it using Fragment's startActivityForResult method.

Please, show us how do you start FilePickerActivity.

OK. I was about to post the same. I was making a mistake of using MaterialFilePicker builder class from Fragment. After some trials and errors, I tried to test by making Intent and startActivityForResult, it worked as expected. Seems like you had already posted about it,
Thanks for this library and your help.
