startActivityForResult not working in fragment and not start an activity

Question

I am trying to startActivityForResult in my fragment and i do this way:

public class MyFragment extends Fragment {
.....
 new GetNidBase(getContext(), code, Integer.parseInt(_newBlock.split("-")[3]),
     WKT1, user, cookie, permissions, _newBlock, (nidBase) -> {
     if (!TextUtils.isEmpty(nidBase)) {
         Intent intent = new Intent(requireContext(), FormSaveDocument.class);
         intent.putExtra(BaseFragment.ARG_COOKIE, HttpUtil.serializeCookie(cookie));
         intent.putExtra(BaseFragment.ARG_USER, common.Utils.compactUserInstance(user));
         intent.putExtra(BaseFragment.ARG_PERMISSIONS, GsonUtil.createGson().toJson(permissions));
         startActivityForResult(intent, INTENTRESULT);
         }

I want to handle my result in fragment's onActivityForResult() But i wondered that, FormSaveDocument is not started? FormSaveDocument is a activity class!!startActivityForResult(intent, INTENTRESULT) not work.

I also trying this:

MyFragment.this.startActivityForResult(intent, INTENTRESULT);

This is onActivityResult in my fragment:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data){
    if (requestCode == INTENTRESULT && resultCode == 20) {
        saveDraw();
    }
}

Update

This is myActivity and FormSaveDocument manifest info:

   <activity
        android:name=".activity.MainActivity"
        android:configChanges="keyboardHidden|orientation|screenSize"
        android:launchMode="singleTop">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    <activity
        android:name=".forms.FormSaveDocument"
        android:configChanges="keyboardHidden|orientation|screenSize" />

    </activity>

are you using context from parent activity? I'm assuming that `requireContext()` is getting the context from parent activity. Is there any error logs? If there are any logs, please add some logs. — Amol Gangadhare, Apr 15 '19 at 05:51
I am calling startActivityForResult() from the fragment then i should call startActivityForResult() and i do it ... @akshay_shahane — Cyrus the Great, Apr 15 '19 at 05:51

"But i wondered that, `FormSaveDocument` is not started?" – If you mean that `FormSaveDocument` is not showing at all, are you sure that that code is executing? — Mike M., Apr 15 '19 at 05:53
are you using context from parent activity? If course, `requireContext()` comes from parent @AmolG — Cyrus the Great, Apr 15 '19 at 05:54
make sure your Host Activity launch mode must not set to singleInstance or singleTask — akshay_shahane, Apr 15 '19 at 05:56
In activity i do : `myFragment.setArguments(args); getSupportFragmentManager().beginTransaction() .addToBackStack(MyFragment.getClass().getName()) .replace(R.id.fragment_holder, myFragment) .commit();` @akshay_shahane — Cyrus the Great, Apr 15 '19 at 05:58
is there any error logs? does the activity is able to start from other ways without any error? — Amol Gangadhare, Apr 15 '19 at 05:59
I do not have any error and logcat is not showing any error and i did not get any error.Just do not started my activity@AmolG — Cyrus the Great, Apr 15 '19 at 06:03
It's really starting to sound like that `startActivityForResult()` line isn't being reached. You might try setting a breakpoint there, or put a log print, or something, just to make sure. — Mike M., Apr 15 '19 at 06:25
I am sure the cursor reach to `startActivityForResult()` and pass from it but `FormSaveDocument` not started and i got any error @MikeM — Cyrus the Great, Apr 15 '19 at 06:27
I am taking a picture from break point to see cursor reach @MikeM. — Cyrus the Great, Apr 15 '19 at 06:29

Well, if `FormSaveDocument` is failing when starting up, there really should be something in [your logcat](https://developer.android.com/studio/debug/am-logcat#running). If you're not seeing anything, you might post `FormSaveDocument` in your question, to see if we notice anything that could be causing an issue. — Mike M., Apr 15 '19 at 06:35

In Your Activity Where you get your result back you have to use same object of fragment which you used to add Fragment.

Please use
startActivityForResult(intent, INTENTRESULT); insted of call MyFragment.this.startActivityForResult(intent, INTENTRESULT); from your fragment, and

Then after handle onActivityResult() in your fragment

This will give you call back in your fragment

Another Solution is:
Handle onActivityResult in your activity

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        try {
            getCurrentFrg().onActivityResult(requestCode,resultCode,data);    
        }catch (Exception e){
            e.printStackTrace();
        }
    }

Okay, Then the final solution is called as you calling and handle onActivityResult in your activity and call fragment onActivityResult from the activity callBack – Dhaval Solanki Apr 15 '19 at 06:15
