Hey.... Check out new tutorial playlist of instag blog app where we are using firebase multiple services. kzfaq.info/sun/PLhhNsarqV6MTHwd8fttCrP2fRijuQ0dah

Check logcat and let me know the error Or exception

@@codingstuff070 Thanks for replying, E/eglCodecCommon: GoldfishAddressSpaceHostMemoryAllocator: ioctl_ping failed for device_type=5, ret=-1 this is logcat red shows only

Most of u r not able to retrieve data... It is causing mainly because of your model class varibles name. Make sure your model class varibles name must be same as child's or fields name in relatime db.

@سلفي على منهاج النبوة we don't need setters as we are using hashmap nd saving the map data to firebase .... Also we have not created parameterize constructor... Cause we don't need that in this tutorial

It's already done man.... Instag blog app tutorial series is finished with 13 parts. Check complete playlist.

@@codingstuff070 thanks

Then u need to use authentication.... Nd use currentUser.getUid() try to match is with user that u u want show the data

​ @CodingSTUFF if u know the solution, pls do the video or show the code ASAP🙏🏻

Yes we have done this query stuff in Instag blog app tutorial series. Checkout that tutorials

@@codingstuff070 okey but i used the realtime database, is that same code of cloud firestore??

No both codes are different but firestore is better choice than real-time db.

Check logcat what exception Or error it is showing

@@codingstuff070 E/SpannableStringBuilder: SPAN_EXCLUSIVE_EXCLUSIVE spans cannot have a zero length

R u testing on samsung device

@@codingstuff070 I tried it already on the emulator. Still does not show any of it. The data can send to firebase but its does not retrieve back when I press the "View List Button". It only display like "Name", "Surname" and "Email" but not the "blablagmail.com" that I previously send earlier.

Send me screenshot of ur code at instagram @codingstuff070

Ok man i have changed it...

@@codingstuff070 thank you 🙂

Send me ur code at Instagram @codingstuff070

Show me ur code photos on Instagram at @codingstuff070 .... When u add onClickListner on button 2

@@codingstuff070 Sure bro , I actually need your email so that i could send you my docx file with pictures included :)

Use cloud firestore.....

Source code is in the description box... Try to match ur code with it... If Still get error let me know...

While uploading u can use hasmap or Java object while updating u can only update value using hashmap while retrieving u should create model class or u can get specific field values using key.

May be u forgot to initialize Arraylist

When u store the images in firebase add time stamp as well .. Then while Retrieving the data apply query orderBy and pass the "time" There.

Watch this video while uploading kzfaq.info/get/bejne/mrRnd6-btr3Jqpc.html And this while retrieving.. U will get the idea kzfaq.info/get/bejne/g5mEpdeS17ithmQ.html

ok i will check it out. I have one more query that in recycler view how we can add the time like i post something and it comes to recycler view and should show 1 sec ago ... 1 min ago relative to time.. any idea??

By that server timestamp u can evaluate the time. SimpleDateFormat format = new SimpleDateFormat("yyyy.MM.dd G 'at' HH:mm:ss"); Date past = format.parse("2016.02.05 AD at 23:59:30"); Date now = new Date(); long seconds=TimeUnit.MILLISECONDS.toSeconds(now.getTime() - past.getTime()); long minutes=TimeUnit.MILLISECONDS.toMinutes(now.getTime() - past.getTime()); long hours=TimeUnit.MILLISECONDS.toHours(now.getTime() - past.getTime()); long days=TimeUnit.MILLISECONDS.toDays(now.getTime() - past.getTime()); // // System.out.println(TimeUnit.MILLISECONDS.toSeconds(now.getTime() - past.getTime()) + " milliseconds ago"); // System.out.println(TimeUnit.MILLISECONDS.toMinutes(now.getTime() - past.getTime()) + " minutes ago"); // System.out.println(TimeUnit.MILLISECONDS.toHours(now.getTime() - past.getTime()) + " hours ago"); // System.out.println(TimeUnit.MILLISECONDS.toDays(now.getTime() - past.getTime()) + " days ago"); if(seconds

Using for loop u can iterate through

Thank you brother 🙏🙏❤

In which class u got this error

Important Context from android.content.Context

@@codingstuff070 Thank You so much!!

Check logcat nd try to match with source code. Source code is in the description box

Most of u r not able to retrieve data... It is causing mainly because of your model class varibles name. Make sure your model class varibles name must be same as child's or fields name in relatime db.

Wht is error in the logcat

May be u have not inflated item Layout in adapter Or not finded id of wigdets in viewholder class.... If u want source code i can definitely provide u.

@@codingstuff070 i done of my inflated, but it still can't show up the data, yes if u can. Or could u can help me to see??

@@codingstuff070 the code similar like this?? View v = LayoutInflater.from(context).inflate(R.layout.item, parent, false);

Match ur model class variables name with firebase child field values. For ex. If it is Name in firebase then make ur model class variable exactly same as Name
