Null response while saving in the database

Android
1

Below is the code I am using to save in the database

// save object asynchronously
        HashMap user = new HashMap();
        user.put( "username", newUser.getUsername());
        user.put( "userid", newUser.getUserID());
        user.put( "avatar", newUser.getAvatarURL());
        user.put( "deviceID", newUser.getDeviceID());
        user.put( "userType", newUser.getUserType());
        user.put( "email", newUser.getEmailAddress());
        user.put( "followerCount", newUser.getFollowersCount());
        user.put( "followingCount", newUser.getFollowingCount());
        user.put( "likeCount", newUser.getLikesCount());

       // Toast.makeText(LoginActivity.this,"User Values "+user,Toast.LENGTH_LONG).show();


        // save object asynchronously
        Backendless.Data.of( "app_users" ).save( user,  new AsyncCallback<Map>() {
            public void handleResponse( Map response )
            {
                // new Contact instance has been saved
                Toast.makeText(LoginActivity.this,"User Created "+response,Toast.LENGTH_LONG).show();
            }

            public void handleFault( BackendlessFault fault )
            {
                Log.d("Error:",""+fault.toString());
                Toast.makeText(LoginActivity.this,"User Failed to be Created ",Toast.LENGTH_LONG).show();
                // an error has occurred, the error code can be retrieved with fault.getCode()
            }
        });

It runs the handleResponse function after the request is complete but returns a null response and also does not store anything in the database

pls help

it’s strange,

  • do you call Backendless.initApp before that code?
  • please provide what the SDK’s version you use
5

I am calling Backendless.initApp in my main activity as the app starts…SDK group: ‘com.backendless’, name: ‘backendless’, version: ‘5.0.+’

Do i need to call Backendless.initApp in every activity?

6

I just ran your code and don’t see any problems, the new object was created,
so try to debug your code

7

can you help with the same…I mean if you are running the same code what should I debug ?

8

try to put a debug breakpoint at this line
Backendless.Data.of( “app_users” ).save( user, new AsyncCallback() {

9

i did this…but Can not figure out the problem…

10

Please keep trying… we really cannot just start writing code for you.

11

really strange…I even can not read data … I entered a record manually using web console…and using the below code , I am trying to read data.

String whereClause = "userid = "+userID;
                DataQueryBuilder queryBuilder = DataQueryBuilder.create();
                queryBuilder.setWhereClause( whereClause );

                Backendless.Data.of( "app_users" ).find( queryBuilder,
                        new AsyncCallback<List<Map>>(){
                            @Override
                            public void handleResponse( List<Map> foundUser )
                            {
                                Log.d("USer ",""+foundUser);
                                // every loaded object from the "Contact" table is now an individual java.util.Map
                            }
                            @Override
                            public void handleFault( BackendlessFault fault )
                            {
                                Log.d("USer ","Error in Finding user");
                                // an error has occurred, the error code can be retrieved with fault.getCode()
                            }
                        });

Reading and writing both are a issue… @vladimir-upirov @mark-piller

Please attach a simple sample project that reproduces this issue.

Sorry but I have shifted to parse… because of no support from backend less

Best of luck to you with parse
