Android Solutions
Solution 1 - Android
Inside a Fragment
subclass you have to use getFragmentManager
in place of getSupportFragmentManager
. You will get the support one if the import are from the support library.
Solution 2 - Android
For my case, I made sure that Fragment class is imported from
> android.support.v4.app.Fragment
Not from
> android.app.Fragment
Then I have used
> getActivity().getSupportFragmentManager();
And now its working. If I use activity instance which I got in onAttach() is not working also.
Solution 3 - Android
Extends FragmentActivity instead of Activity
Solution 4 - Android
Use getActivity().getSupportFragmentManager()
Solution 5 - Android
Replace getSupportFragmentManager()
with getFragmentManager()
if you are working in api 21.
OR
If your app supports versions of Android older than 3.0, be sure you've set up your Android project with the support library as described in Setting Up a Project to Use a Library and use getSupportFragmentManager()
this time.
Solution 6 - Android
Also you can use AppCompatActivity
instead of Activity.
Then getSupportFragmentManager()
will work.
And also not forget to make your App theme extend AppCompat theme in this case
Solution 7 - Android
As per the documentation, getSupportFragmentManager() is present only inside AppCompatActivity class. It is not present inside Activity class. So make sure your class extends AppCompatActivity class.
public class MainActivity extends AppCompatActivity {
}
Solution 8 - Android
getSupportFragmentManager()
is not part of Fragment
, so you cannot get it here that way. You can get it from parent Activity
(so in onAttach()
the earliest) using normal
activity.getSupportFragmentManager();
or you can try getChildFragmentManager(), which is in scope of Fragment, but requires API17+
Solution 9 - Android
> getFragmentManager()
just try this.it worked for my case
Solution 10 - Android
you should use
getActivity.getSupportFragmentManager() like
//in my fragment
SupportMapFragment fm = (SupportMapFragment)
getActivity().getSupportFragmentManager().findFragmentById(R.id.map);
I have also this issues but resolved after adding getActivity()
before getSupportFragmentManager
.
Solution 11 - Android
If you're getting "Cannot resolve method getSupportFragmentManager()", try using
this.getSupportFragmentManager()
It works for me when dealing with DialogFragments in android
Solution 12 - Android
If you're instantiating an android.support.v4.app.Fragment
class, the you have to call getActivity().getSupportFragmentManager()
to get rid of the cannot-resolve problem. However the official Android docs on Fragment by Google tends to over look this simple problem and they still document it without the getActivity()
prefix.
Solution 13 - Android
For me I made sure to import v4 like this:
import android.support.v4.app.DialogFragment;
Then used:
getActivity().getFragmentManager()
Solution 14 - Android
I tried all above, but none working
Finally tried this my own
getBaseActivity().getFragmentManager()
and is working .. :)
