How to restore fragment states while using bottom navigation view in android?

I am trying to do restoring the fragment view state values(text view,..etc) when back from second fragment in android bottom navigation view.

Here in ProductFragment iam going to add values to text view. When i was coming from ReportFragment the view values are going to be cleared in ProductFragment.

I would consider doing that in two steps:
save fragment instance instead of re-creating a new one every time
private ProductFragment productFragment;
private ReportsFragment reportsFragment;
private BottomNavigationView.OnNavigationItemSelectedListener mOnNavigationItemSelectedListener = new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.nav_home:
if(productFragment == null)
productFragment = new ProductFragment();
loadFragment(productFragment);
break;
case R.id.nav_profile:
if(reportsFragment == null)
reportsFragment = new ReportsFragment();
loadFragment(reportsFragment);
break;
case R.id.nav_logout:
LogOut();
return true;
}
return true;
}
};
referring to this question/answer, you should implement in your fragment both void onSaveInstanceState(final Bundle outState) and void onActivityCreated(Bundle savedInstanceState)
In that way you will surely keep the instance of your fragment instead of creating a new one every time (new MyFragment() will always re-create it). In addition, saving your views state in onSaveInstanceState and restoring it in your onActivityCreate, will allow you to keep your views/values.
I wrote that by hand without a compiler, so it might not be perfect.
let me know if you need further information.
Good luck

I am using this solution and it works for me.

You should see my detailed answer to a similar question. I hope it will solve your problem.

You tried with other real devices? It's same issue?
This type of error happen when VM heap is Low and in that secession you should increase your ADB emulator Heap to the minimum required.
Into your AVD Manager :
Click Edit on your Emulator
"Show Advanced Settings" at the bottom
Go to: "Memory and Storage"
Edit the VM heap value to 512 MB

Adding Class Activity to Navigation Drawer Android

Can you tell me how to add class activity into navigation drawer? I am going to create one app where i need to have more than one classes. all of these classes extends activity.I know how to add fragment into navigation drawer but i dont understand how do i add class activity into navigation drawer.

You can add activity for this code....

viewpager didn't load the first page at the first time, but will load it after swipe to the last page

I am new to Android development and I don't have too much SO coins.
Basically, my project has a main screen activity and it contains 3 tabs, which are MyGiftsFragment, FriendsGiftsFragment and AboutMeFragment. I implemented tablayout and viewpager here. The problem is when I sign in the app, the first page(MyGiftsFragment) is empty, not loading anything(sometimes it loaded.) But when I swiped to the last tab(AboutMeFragment) and come back to the first tab, the content will be loaded. And this only works when I swiped to the last tab.
Due to my limit English, I am not sure if I explain the question clear. If you need any further information, please comment. I've searched the "setUserVisibleHint" and "setOnPageChangeListener(pageChangeListener)", but it seems that they are not what I want. Any advice will be appreciated. Thank you so much.
Here are my MainScreenActivity code.

Please add this line before setting adapter. This will fix the issue
viewPager.setOffscreenPageLimit(3);
Offscreen page limit will decide how many adjacent pages need to be loaded when you see a page. So in your case set it to 3 (all pages).
Then your code will change to,
final ViewPager viewPager = (ViewPager)findViewById(R.id.viewpager);
viewPager.setAdapter(adapter);
viewPager.setOffscreenPageLimit(3); //Add this
viewPager.setCurrentItem(0);
Good luck!

Android Application - Get last fragment for each activity if already loaded

I actually have an aplication with multiple activitys (on for each icon of my toolbar), also I would like to have the possibility to show the last fragment of these activitys from the stack if the user already open it before.
As you can see in my BaseActivity class below (which I extend for all my activitys), I already add fragments to the stack.
This is my class :
public class BaseActivity extends AppCompatActivity {
private final String TAG = "BaseActivity";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_base);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
return false;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
return super.onOptionsItemSelected(item);
}
public void setImageLoaderConfig(Context context) {
DisplayImageOptions defaultOptions = new DisplayImageOptions.Builder()
.cacheInMemory(true).cacheOnDisk(true)
.resetViewBeforeLoading(true)
.build();
ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context)
.defaultDisplayImageOptions(defaultOptions)
.build();
ImageLoader.getInstance().init(config);
}

Thanks in advance for your replys :)

You can get current fragment(last one added) in the FrameLayout using:
Fragment fragment = getSupportFragmentManager().findFragmentById(layoutId); //layoutId is id of FrameLayout
