Fragment showing Old Data - android-fragments

Question

I am new to android programming. I am implementing functionality to scan particular Inventory Item and search for the barcode if it already exists in an ArrayList. If it exists then I am replacing the current Scan fragment with the InvnetoryFound Fragment in which I have option to update quantity and completely remove item from ArrayList.
The issue I am facing is, after removing Inventory when I scan again for different Inventory barcode, upon successful scan, it is showing InventoryFound Fragment with old data that was removed from ArrayList. Below is my code:
Test ArrayList Code:
public static String[] inve = new String[5];
public static ArrayList<String[]> inventory_list = new ArrayList<String[]>();
inve[0] = "INV45879";
inve[1] = "Bridge Support Pipe";
inve[2] = "Pre-insulated pipe supports provide both support and insulation in hot and cold piping applications.Pre-insulated pipe supports provide both support and insulation in hot and cold piping applications.";
inve[3] = "0885370720679";
inve[4] = "2";
inventory_list.add(inve);
inve = new String[5];
inve[0] = "INV45880";
inve[1] = "Cement";
inve[2] = "Pre-insulated pipe supports provide both support and insulation in hot and cold piping applications";
inve[3] = "9771234567003";
inve[4] = "8";
inventory_list.add(inve);
If scan is successful it calls below function to replace fragment:
private static void showFragment(Fragment fragment, String back_option) {
try {
// start transition
FragmentTransaction ft = activity.getFragmentManager().beginTransaction();
//if fragment Inventory is found then pass data to fragment
if(back_option.equals("inventoryFound")){
//sends found inventory list data to fragment
String[] inv_data = inventory_list.get(inventory_index);
Bundle bundle = new Bundle();
bundle.putStringArray("inventory_data",inv_data);
bundle.putInt("inventory_index",inventory_index);
inventoryFoundFragment.setArguments(bundle);
back_option = "null";
// replace fragment
if (!back_option.equals("null")) // with back option
ft.replace(R.id.frag_content, fragment).addToBackStack(back_option);
else // no back option
ft.replace(R.id.frag_content, fragment);
// commit
ft.commit();
}
catch(Exception e){
out("PROBLEM SHOWING FRAGMENT!!!"+e.getMessage());
}
}
InventoryFound fragment populates data and works fine. Below is the code when I click on Remove populated Inventory:
public void removeInventory(){
Shared.inventory_list.remove(inventory_index);
Toast.makeText(mContext,"Inventory "+inventory_index+" Removed Successfully!", Toast.LENGTH_SHORT).show();
FragmentTransaction ft = getActivity().getFragmentManager().beginTransaction();
ft.remove(this);
ft.replace(R.id.frag_content, new ScanFragment());
ft.commit();
}
It is removing successfully but when I scan it again e.g. for barcode "0885370720679" it shows the previous data on InventoryFound fragment. I have debugged it in Logcat (Log.d) and I am able to see correct data but it is not displaying in fragment.
any suggestions or guidance will be appreciated.

I found the solution for this problem.
When Fragment is in foreground, it calls onResume() method. In this method I call user-defined function which re-sets the data for Fragment fields. I don't know if it's a correct to way to fix this issue but it's working for me now!
