android - How many levels does Firebase ChildEventListener listen to -

-

my current android application uses firebase store user data.

my data has following "structure" (and/or levels)

my-android-app.firebaseio.com/level0/level1/uuid1/uuid2

data objects stored @ uuid2 resemble this

{    "students":[       {          "name":"amit goenka",          "major":"physics"       },       {          "name":"smita pallod",          "major":"chemistry"       },       {          "name":"rajeev sen",          "major":"mathematics"       }    ] }

i need able detect when child data added, removed or changed etc below (at) uuid2, want set childeventlistener using path

android-app.firebaseio.com/level0/level1

is possible?

during test far have had specify full path of:-

my-android-app.firebaseio.com/level0/level1/uuid1/uuid2

firebase fire child_* event change under level register correct listener. fire child_added/child_removed nodes added/removed directly under level registered. other changes, fire child_changed , possibly child_moved.

your options:

  • flatten tree
  • listen value events
  • listen child_ events , figure out changes

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...
