move from Activity to fragment

i have a fragment say F1 and from there i'm opening an activity say A1 and after that activity (A1) i'm opening other activity (A2) and i'm performing some tasks in A2 now once my task is over in my activity (A2) i want to destroy current opened Activities and move back to my fragment F1.

this is what i'm trying to get back to my fragment:

    Intent intent = new Intent(context, myFragment.class);
    overridePendingTransition(0, 0);
    intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
    finish();
    startActivity(intent);

but i'm getting this error : Unable to find explicit activity class

and i know why i'm getting this (cause specified class is not an activity that is a Fragment ) but my question is how can i move back to that fragment ?

Put below code in your Activity from which you want to move.

btnDone.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
   Intent intent = new Intent(SelectLocation.this,MainActivity.class);
   intent .putExtra("tag",true);
   finish();
   startActivity(intent);
        }
    });

and put below code inside oncreate methodin your activity in which you have attatched all fragments.

public void onCreate(Bundle savedInstanceState){
Bundle extras = getIntent().getExtras();
if(extras!=null && extras.containsKey("flag"))
 boolean flag= extras.getBoolean("flag");
   if(flag){
      currentFragment = getOneFragment();
   }
 }

this will work properly for you .

You cannot start a Fragment with intent. your every fragment will be attached to some activity. Fragments can be replaced or added in activity,

What you can do is : Your fragment F1 is attached to some activity...say A0. So what you can do is like this :

  Intent intent = new Intent(context, A0.class);
intent .putExtra("openF2",true)
    overridePendingTransition(0, 0); 
    intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
    finish(); 
    startActivity(intent);

then, inside your activity A0's onCreate you can check for which fragment to replace:

public void onCreate(Bundle savedInstanceState){
Bundle extras = getIntent().getExtras();
 if(extras!=null && extras.containsKey("openF2"))
  boolean openF2 = extras.getBoolean("openF2");
if(openF2){
  //add or replace fragment F2 in container
 }
}

This is just pseudo code. I hope you will understand it.

Edit: If you want to move back to that previous fragment, you can explicitly call activity's onBackPress() twice to go back to your activity say A0 which contains the fragment. Not a good idea though.
