With Android s Navigation component  this problem  when you have nested Fragments  could feel like an unsolvable mystery   Based on knowledge and inspiration from the following answers in this post  I managed to make up a simple solution that works    Answer in this post Answer in this post   In your activity s onActivityResult    you can loop through the active Fragments list that you get using the FragmentManager s getFragments   method   Please note that for you to do this  you need to be using the getSupportFragmentManager   or targeting API 26 and above   The idea here is to loop through the list checking the instance type of each Fragment in the list  using instanceof   While looping through this list of type Fragment is ideal  unfortunately  when you re using the Android Navigation Component  the list will only have one item  i e  NavHostFragment   So now what  We need to get Fragments known to the NavHostFragment  NavHostFragment in itself is a Fragment  So using getChildFragmentManager   getFragments    we once again get a List lt Fragment gt  of Fragments known to our NavHostFragment  We loop through that list checking the instanceof each Fragment   Once we find our Fragment of interest in the list  we call its onActivityResult    passing to it all the parameters that the Activity s onActivityResult   declares    x000D   x000D      Your activity s onActivityResult   x000D   x000D   Override x000D  protected void onActivityResult int requestCode  int resultCode   Nullable Intent data    x000D          super onActivityResult requestCode  resultCode  data   x000D   x000D          List lt Fragment gt  lsActiveFragments   getSupportFragmentManager   getFragments    x000D          for  Fragment fragmentActive   lsActiveFragments    x000D   x000D              if  fragmentActive instanceof NavHostFragment    x000D   x000D                  List lt Fragment gt  lsActiveSubFragments   fragmentActive getChildFragmentManager   getFragments    x000D                  for  Fragment fragmentActiveSub   lsActiveSubFragments    x000D   x000D                      if  fragmentActiveSub instanceof FragWeAreInterestedIn    x000D                          fragmentActiveSub onActivityResult requestCode  resultCode  data   x000D                        x000D   x000D                    x000D   x000D                x000D   x000D            x000D   x000D        x000D   x000D   x000D

Most of these answers keep saying that you have to call super onActivityResult      in your host Activity for your Fragment  But that did not seem to be working for me   So  in your host Activity you should call your Fragments onActivityResult      instead  Here is an example   public class HostActivity extends Activity        private MyFragment myFragment       protected void onActivityResult                super onActivityResult               this myFragment onActivityResult                 At some point in your HostActivity you will need to assign this myFragment the Fragment you are using  Or  use the FragmentManager to get the Fragment instead of keeping a reference to it in your HostActivity  Also  check for null before you try to call the this myFragment onActivityResult

Inside your fragment  call  this startActivityForResult intent  REQUEST CODE     where this is referring to the fragment  Otherwise do as  Clevester said   Fragment fragment   this       fragment startActivityForResult intent  REQUEST CODE     I also had to call  super onActivityResult requestCode  resultCode  data     in the parent activity s onActivityResult to make it work    I adapted this answer from  Clevester s answer

The hosting activity overrides onActivityResult    but it did not make a call to super onActivityResult   for unhandled result codes  Apparently  even though the fragment is the one making the startActivityForResult   call  the activity gets the first shot at handling the result  This makes sense when you consider the modularity of fragments  Once I implemented super onActivityResult   for all unhandled results  the fragment got a shot at handling the result   And also from  siqing answer   To get the result in your fragment make sure you call startActivityForResult intent 111   instead of getActivity   startActivityForResult intent 111   inside your fragment

I have a strong suspicion that all of the answers here are nothing more than hacks  I ve tried them all and many others  but without any reliable conclusion as there is always some sort of stupid issue  I for one cannot rely on inconsistent results  If you look at the official Android API documentation for Fragments you will see Google clearly states the following      Call startActivityForResult Intent  int  from the fragment s containing Activity    See  Android Fragment API  So  it would seem that the most correct and reliable approach would be to actually call startActivityForResult   from the hosting activity and also handle the resulting onActivityResult   from there

first of all you need to override this code in Activity     Override public void onActivityResult int requestCode  int resultCode   Nullable Intent data        super onActivityResult requestCode  resultCode  data       and after  in your fragment   startActivityForResult intent GALLERY REQUEST CODE     and again than in your fragment    Override public void onActivityResult int requestCode  int resultCode   Nullable Intent data        super onActivityResult requestCode  resultCode  data          Result code is RESULT OK only if the user selects an Image     if  resultCode    Activity RESULT OK

Your code has a nested fragment  Calling super onActivityForResult doesn t work  You don t want to modify every activity that your fragment can be called from and or make a work around calling every fragment in the fragment chain   Here is one of many working solutions  create a fragment on the fly and wire it directly to the activity with the support fragment manager  Then call startActivityForResult from the newly created fragment   private void get UserEmail          if  view    null            return              TextView  view findViewById R id tvApplicationUserName                setText  Searching device for user accounts            final FragmentManager fragManager   getActivity   getSupportFragmentManager         Fragment f   new Fragment              Override         public void onAttach Activity activity                super onAttach activity               startActivityForResult AccountPicker newChooseAccountIntent null  null                      new String    com google    false  null  null  null  null   REQUEST CODE PICK ACCOUNT                       Override         public void onActivityResult int requestCode  int resultCode                                       Intent data                if  requestCode    REQUEST CODE PICK ACCOUNT                    String mEmail                       if  resultCode    Activity RESULT OK                        if  data hasExtra AccountManager KEY ACCOUNT NAME                             mEmail   data                                  getStringExtra AccountManager KEY ACCOUNT NAME                                                           if  mActivity    null                        GoPreferences putString mActivity  SettingApplication USER EMAIL  mEmail                                     doUser                              super onActivityResult requestCode  resultCode  data               fragManager beginTransaction   remove this  commit                         FragmentTransaction fragmentTransaction   fragManager              beginTransaction        fragmentTransaction add f   xx    REQUEST CODE PICK ACCOUNT       fragmentTransaction commit

One point no one has mention that make sure your Host Activity launch mode must not set to singleInstance or singleTask    onActivityResult will not work if your launch mode set to SingleInstance or SingleTask  or you call your activity using these IntentFilters  standard or singleTop launch mode will work fine

Original post   FragmentActivity replaces requestCode by a modified one  After that  when onActivityResult   will be invoked  FragmentActivity parses the higher 16 bits and restores the index of the original Fragment  Look at this scheme     If you have a few fragments at the root level there are no problems  But if you have nested fragments  for example Fragment with a few tabs inside ViewPager  you guaranteed will face with a problem  or already faced it    Because only one index is stored inside requestCode  That is index of Fragment inside its FragmentManager  When we are using nested fragments  there are child FragmentManagers  which have their own list of Fragments  So  it s necessary to save the whole chain of indices  starting from root FragmentManager     How do we resolve this issue  There is common workaround solution in this post   GitHub  https   github com shamanland nested-fragment-issue

If there is trouble with the method onActivityResult that is inside the fragment class  and you want to update something that s is also inside the fragment class  use    Override public void onActivityResult int requestCode  int resultCode  Intent data         if resultCode    Activity RESULT OK                   If the user had agreed to enabling Bluetooth             populate the ListView with all the paired devices          this arrayDevice   new ArrayAdapter lt String gt  this getContext    R layout device item           for BluetoothDevice bd   this btService btAdapater getBondedDevices                          this arrayDevice add bd getAddress                 this btDeviceList setAdapter this arrayDevice                       super onActivityResult requestCode  resultCode  data       Just add the this variable as shown in the code above  Otherwise the method will be called within the parent activity and the variable will not updated of the current instance   I tested it also by putting this block of code into the MainActivity  replacing this with the HomeFragment class and having the variables static  I got results as I expected   So if you want to have the fragment class having its own implementation of onActivityResult  the code example above is the answer

This is one of the most popular issue  We can found lots of thread regarding this issue  But none of them is useful for ME    So I have solved this problem using this solution   Let s first understand why this is happening   We can call startActivityForResult directly from Fragment but actually mechanic behind are all handled by Activity   Once you call startActivityForResult from a Fragment  requestCode will be changed to attach Fragment s identity to the code  That will let Activity be able to track back that who send this request once result is received   Once Activity was navigated back  the result will be sent to Activity s onActivityResult with the modified requestCode which will be decoded to original requestCode   Fragment s identity  After that  Activity will send the Activity Result to that Fragment through onActivityResult  And it s all done   The problem is   Activity could send the result to only the Fragment that has been attached directly to Activity but not the nested one  That s the reason why onActivityResult of nested fragment would never been called no matter what   Solution    1  Start Intent in your Fragment by below code              Pass your fragment reference            frag startActivityForResult intent  REQUEST CODE      REQUEST CODE   12345   2  Now in your Parent Activity override   onActivityResult             Override     protected void onActivityResult int requestCode  int resultCode  Intent data            super onActivityResult requestCode  resultCode  data           You have to call this in parent activity to make it work   3  In your fragment call    Override     public void onActivityResult int requestCode  int resultCode  Intent data            super onActivityResult requestCode  resultCode  data           if  resultCode    Activity RESULT OK                  That s it  With this solution  it could be applied for any single fragment whether it is nested or not  And yes  it also covers all the case  Moreover  the codes are also nice and clean

Option 1   If you re calling startActivityForResult   from the fragment then you should call startActivityForResult    not getActivity   startActivityForResult    as it will result in fragment onActivityResult     If you re not sure where you re calling on startActivityForResult   and how you will be calling methods   Option 2   Since Activity gets the result of onActivityResult    you will need to override the activity s onActivityResult   and call super onActivityResult   to propagate to the respective fragment for unhandled results codes or for all   If above two options do not work  then refer to option 3 as it will definitely work   Option 3   An explicit call from fragment to the onActivityResult function is as follows   In the parent Activity class  override the onActivityResult   method and even override the same in the Fragment class and call as the following code   In the parent class    Override protected void onActivityResult int requestCode  int resultCode  Intent data        Fragment fragment   getSupportFragmentManager   findFragmentById R id dualPane       fragment onActivityResult requestCode  resultCode  data       In the child class    Override protected void onActivityResult int requestCode  int resultCode  Intent data           In fragment class callback

I was also facing the same problem once I shifted this block of code outside of a Fragment to a Utility Class  with parentActivity passed as argument   Intent intent   new Intent parentActivity  CameraCaptureActivity class   parentActivity startActivityForResult intent requestCode     Then I was not getting any value in onActivityResult method of that Fragment  Afterwards  I changed the argument to Fragment  so the revised definition of method looked like   Intent intent   new Intent fragment getContext    CameraCaptureActivity class   fragment startActivityForResult intent requestCode     After that  I was able to get value in onActivityResult on the Fragment

As Ollie C mentioned  there is an active bug for the support library using returned values to onActivityResult when you are using nested fragments  I just hit it  -    See Fragment onActivityResult not called when requestCode    0

One of the simplest way is to start an activity from your fragment    startActivity ActivityName     Then  add you call startActivityForResult intent  1    from your Activity and add onActivityResult in your activity  startActivityForResult intent  1      Override protected void onActivityResult int requestCode  int resultCode  Intent data        Fragment fragment   getSupportFragmentManager   findFragmentById R id dualPane       fragment onActivityResult requestCode  resultCode  data      perform other activity result like fetching from Uris or handling cursors  finish       finish the activity will  get to back to your fragment
