Unable to instantiate fragment could not find Fragment constructor android

I am having this following error. I added constructor on DailyVerseFragment. But still it doesn't work.
I am having this issues for more than one week.
Fatal Exception: java.lang.RuntimeException

The Problem that caused your crash is that you want to instantiate your fragment with a constructor with parameter. but you in android you should create fragment with a non parameter constructor.
so how to solve this problem to pass parameters in to your fragment:
in DailyVerseFragment :
public static DailyVerseFragment newInstance(String myString) {
DailyVerseFragment myFragment = new DailyVerseFragment();
Bundle args = new Bundle();
args.putString("key", myString);
myFragment.setArguments(args);
return myFragment;
}
and in onCreate() function of fragment get it like :
getArguments().getString("key");
and if you want to send Objects you can use putParcable/getParcable.
but my suggestion for you to get toolbar in your fragment is to access it in your fragment like this:
((AppCompatActivity) getActivity()).getSupportActionBar()

java.lang.NullPointerException at firebase.auth.FirebaseUser.getEmail() and says currentUser() returns null

"In my MainActivity , I perform fragment transaction to the profile fragment in my app . In Profile I use FirebaseAuth to get Current User Email Address which then says getEmail() may produce Null Pointer Exception.. But in MainActivity Itself there is a AuthStateListener which should ask the user to sign in if the user is not signed in.. But why it is not happening .. "
"I have read other answers which say NullPointerException on getUid on FirebaseUser is returning Null Pointer exception and those answers didn't help me..."
"
Below I'm Posting my mainActivity and then Profile Fragment
I MARKED THE LINES WITH ARROW'S <-

You can do this with EventBus or Interface. You can follow these steps for EventBus.
Implement EventBus
implementation 'org.greenrobot:eventbus:3.1.1'
EventBustDataEvents.class
public class EventBusDataEvents{
public static class isClick {
boolean isClick;
public isClick(boolean isClick) {
this.isClick = isClick;
}
public boolean getIsClick() {
return isClick;
}
public void setIsClick(boolean isClick) {
this.isClick = isClick;
}
}
}
MainActivity.class
EventBus.getDefault().postSticky(new EventBusDataEvents.isClick(true));
Fragment.class
#Subscribe(sticky = true, threadMode = ThreadMode.MAIN)
public void isClick(EventBusDataEvents.isClick click) {
if (click.isClick()) {
}
}
#Override
public void onStart() {
super.onStart();
try {
EventBus.getDefault().register(this);
} catch (Exception e) {
}
}
#Override
public void onDestroy() {
super.onDestroy();
try {
EventBus.getDefault().unregister(this);
} catch (Exception e) {
}
}
Or Interface
IMainActivity.class // interface class
public interface IMainActivity {
void onClick();}
MainActivity.class
private IMainActivity listener; //This will be described above as a field.
public void setOnEventListener(IMainActivity listener) {
IMainActivity = listener;
}
//buttonClickEvent
listener.OnClick();
Fragment.class
//onCreateView
setOnEventListener(new IMainActivity() {
#Override
public void onClick() {
}
});

I reviewed your code and solved your problem.
There are two things need to discuss.
Your API providing the results according to localisation.If we change first two fields results will remain same and web service is fetching only one item with localisation 'oran'. But if we change localisation from 'oran' to 'alger' web service is displaying 4 results.
Here is the problem in your code.You are not concatenating your results properly in your data string. I have updated your code and now your code of AsyncCaller in announces Activity should be like:
Here is the code
private class AsyncCaller extends AsyncTask<Void, Void, Void>
{
ProgressDialog pdLoading = new ProgressDialog(annonces.this);
#Override
protected void onPreExecute() {
super.onPreExecute();
//this method will be running on UI thread
pdLoading.setMessage("/tChargement des annonces en cours ... ");
pdLoading.show();
}
#SuppressLint("NewApi")
#Override
protected Void doInBackground(Void... params) {
try {
URL url = new URL("https://www.waslup.pw/wp-admin/admin-ajax.php?action=do_ajax&fn=get_posts&count=10&key="+skey+"&cat="+scat+"&loc="+sloc);
HttpURLConnection httpuc = (HttpURLConnection) url.openConnection();
InputStream inputstream = httpuc.getInputStream();
BufferedReader bf = new BufferedReader(new InputStreamReader(inputstream));
StringBuilder total = new StringBuilder();
String line;
while ((line = bf.readLine()) != null) {
total.append(line).append('\n');
}
JSONArray JA = null;
JA = new JSONArray(total.toString());
annonces.Items.removeAll(annonces.Items);
for (int i=0 ; i<JA.length();i++){
JSONObject JO =(JSONObject) JA.get(i);
date =""+ JO.get("date");
loc =""+ JO.get("loc");
cat =""+ JO.get("Cat");
vue =""+ JO.get("vue");
titre =""+ JO.get("title");
id =""+ JO.get("Id");
annonces.Items.add(new annonce_item(id,date,loc,cat,vue,titre));
}
} catch (MalformedURLException e) {
} catch (JSONException e) {
Log.d("js_ex:",e.toString());
} catch (IOException e) {
Log.d("io_ex:",e.toString());
}
return null;
}
#Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
//this method will be running on UI thread
pdLoading.dismiss();
final MyCustomAdapter myadpter = new MyCustomAdapter(Items);
ListView ls = (ListView) findViewById(R.id.listannonce);
ls.setAdapter(myadpter);
ls.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
TextView titre = (TextView) view.findViewById(R.id.titre);
Toast.makeText(getApplicationContext(), titre.getText(), Toast.LENGTH_LONG).show();
myadpter.notifyDataSetChanged();
TextView id2 = (TextView) view.findViewById(R.id.id);
Intent intent = new Intent(getBaseContext(), annonce_details.class);
intent.putExtra("id_from_annonces_activity", id2.getText());
startActivity(intent);
}
});
}
}
In this code i added this part
StringBuilder total = new StringBuilder();
String line;
while ((line = bf.readLine()) != null) {
total.append(line).append('\n');
}
JSONArray JA = null;
JA = new JSONArray(total.toString());

performItemClick on item in Android Navigation Drawer not working

I have a sliding drawer, and in the drawer is a ListView with 4 items. I would like to use performItemClick to programmatically click one of the items in the drawer, but no matter what I try the code seemingly does nothing. When the item is clicked it's supposed to replace the fragment currently in view with another fragment, and change the action bar title. But none of those things happen with I run performItemClick.
Here is the performItemClick, in a BroadcastReceiver which is receiving a Broadcast
private BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
mDrawerList.performItemClick(mDrawerList.getAdapter().getView(1, null, null),1,mDrawerList.getAdapter().getItemId(1));
Log.d("receiver", "Got message + item clicked");
}
};
And here is the code for the actual activity which contains the performItemClick and the drawer itself, along with the drawers fragments (the performItemClick is near the bottom).

What I have done is something like this inside my Expandable listview adapter for Drawer..
View.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
switch (groupPosition)
{
case 0:
switch (childPosition)
{
case 0:
if (groupPosition == 0 && childPosition == 0)
{ some code }
Edit: this switch starts different activity (or change view if fragment) on each respective item click.. in your case their will be fragments..
