json - Get data from firebase realtime database in android -

-



i trying data firebase realtime database in android. have created json data file , imported json file in firebase database. data file looks :

{     "data": [         {         "name" : "one",         "age" : "ten"         },{         "name" : "two",         "age" : "twenty"         }     ] }

i have created pojo class. how can json objects array? i've searched while can't understand reference & child here.

i recommend changing firebase structure following:

  • replace [] {} firebase recommends using practice
  • add specific unique id every user(or item) have in data node.

take example:

enter image description here

as can see in picture every user has specific id. firebase provides every user unique id can string userid= user.getuid();.

you can create unique ids aswell , them using string key = database.child("users").push().getkey(); (not advised used user ids)

if wish read data structured recommend reading this.

also read this.
