How to go back to previous fragment from activity?

I've got an app with nav drawer, which is switching fragments. From inside one of those fragments, I am calling a new activity. When I click back in this activity (in toolbar), I want to go back to previous selected fragment but instead it puts me back to first fragment. I am adding my fragment to back stack so this should not be a problem.

Here is what I have already tried:

I have overriden the onBackPressed method in my 2nd activity like this:

public void onBackPressed() {
if (getFragmentManager().getBackStackEntryCount() == 0) {
} else {

It is not working. I also saved index of current fragment inside onsaveinstancestate method and retrieve it but same result. I also tried with always putting current fragment inside variable and try to reshow it but still, it does not work. Anything else I could try?

Fun fact: if I press back inside bottom panel, it does actually goes back to previous fragment.

EDIT: Here is my code for doing this:

private void replaceFragment(Fragment fragment)
if (fragment != null)
FragmentManager manager = getSupportFragmentManager();
.replace(R.id.main_content, fragment)

I add first fragment only, if savedInstanceState is null, like so:

if (savedInstanceState == null) {
// first time
mTitle = getResources().getString(R.string.home);

And yes, all this is done inside onCreate() method.


I see, that people are still trying to help me. This answer helped me fix my problem: Android - Navigation Up from Activity to Fragment
