startActivityForResult() from a Fragment and finishing child Activity, doesn't call onActivityResult() in Fragment

Question

You must write onActivityResult() in your FirstActivity.Java as follows

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

So this will call your fragment's onActivityResult()

Edit: the solution is to replace getActivity().startActivityForResult(i, 1); with startActivityForResult(i, 1);

Kevin's answer works but It makes it hard to play with the data using that solution.

Best solution is don't start startActivityForResult() on activity level.

in your case don't call getActivity().startActivityForResult(i, 1);

Instead, just use startActivityForResult() and it will work perfectly fine! :)

You must write onActivityResult() in your FirstActivity.Java as follows

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    for (Fragment fragment : getSupportFragmentManager().getFragments()) {
        fragment.onActivityResult(requestCode, resultCode, data);
    }
}

This will trigger onActivityResult method of fragments on FirstActivity.java

The fragment already has startActivityForResult, which would call onActivityResult in the fragment if you use it, instead of getActivity()...

The most important thing, that all are missing here is... The launchMode of FirstActivity must be singleTop. If it is singleInstance, the onActivityResult in FragmentA will be called just after calling the startActivityForResult method. So, It will not wait for calling of the finish() method in SecondActivity.

So go through the following steps, It will definitely work as it worked for me too after a long research.

In AndroidManifest.xml file, make launchMode of FirstActivity.Java as singleTop.

<activity
        android:name=".FirstActivity"
        android:label="@string/title_activity_main"
        android:launchMode="singleTop"
        android:theme="@style/AppTheme.NoActionBar" />

In FirstActivity.java, override onActivityResult method. As this will call the onActivityResult of FragmentA.

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

In FragmentA.Java, override onActivityResult method

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    Log.d("FragmentA.java","onActivityResult called");
}

Call startActivityForResult(intent, HOMEWORK_POST_ACTIVITY); from FragmentA.Java

Call finish(); method in SecondActivity.java

Hope this will work.

We could call startActivityForResult() directly from Fragment So You should call this.startActivityForResult(i, 1); instead of getActivity().startActivityForResult(i, 1);

Intent i = new Intent(getActivity(), SecondActivity.class);
i.putExtra("helloString", helloString);
this.startActivityForResult(i, 1);

Activity will send the Activity Result to your Fragment.
