java - Problems with one-to-one, one-to-many and multithreading in Android (GreenDAO) -
good day. i'm new in using greendao, problems may seem silly you.
i'm working on project contact server , save responses database through greendao. requests server made through service runs in separate thread. so, problem when put data in database in service well. but, when try them out of database through presenter of activity, fields annotation @toone or @tomany in responsenetermin = null. put logs in end of post, can helps understand problem here of entities:
@entity(active = true) public class responseethermine implements iresponse, serializable { @id(autoincrement = true) private long id; @serializedname("address") @expose private string address; private long workersid; @serializedname("workers") @expose @toone(joinproperty = "workersid") private workersethermine workers; @serializedname("unpaid") @expose private long unpaid; @serializedname("rounds") @expose @tomany(referencedjoinproperty = "responseid") private list<roundethermine> rounds; private long settingsid; @serializedname("settings") @expose @toone(joinproperty = "settingsid") private settingsethermine settings; @serializedname("hashrate") @expose private string hashrate; @serializedname("avghashrate") @expose private double avghashrate; @serializedname("reportedhashrate") @expose private string reportedhashrate; private long minerstatsid; @serializedname("minerstats") @expose @toone(joinproperty = "minerstatsid") private minerstatsethermine minerstats; @serializedname("ethpermin") @expose private double ethpermin; @serializedname("usdpermin") @expose private double usdpermin; @serializedname("btcpermin") @expose private double btcpermin; } @entity(active = true) public class settingsethermine implements serializable{ @id(autoincrement = true) private long id; @serializedname("miner") @expose private string miner; @serializedname("email") @expose private string email; @serializedname("monitor") @expose private long monitor; @serializedname("minpayout") @expose private long minpayout; private final static long serialversionuid = 1164269290012137915l; } @entity(active = true) public class workersethermine implements serializable{ @id(autoincrement = true) private long id; @expose @tomany(referencedjoinproperty = "workersid") private list<workerethermine> workersethermine; private final static long serialversionuid = 2224269290012137915l; } @entity(active = true) public class workerethermine implements itemsrecyclerview, serializable { @id(autoincrement = true) private long id; @serializedname("worker") @expose private string worker; @serializedname("hashrate") @expose private string hashrate; @serializedname("reportedhashrate") @expose private string reportedhashrate; @serializedname("validshares") @expose private long validshares; @serializedname("invalidshares") @expose private long invalidshares; @serializedname("staleshares") @expose private long staleshares; @serializedname("workerlastsubmittime") @expose private long workerlastsubmittime; @serializedname("invalidshareratio") @expose private long invalidshareratio; private long workersid; private final static long serialversionuid = -5303263359818635190l; } the service stores data in database this:
databasehelper databasehelper = databasehelper.getinstance(); for(responseethermine response : lastresponsesethermine) { databasehelper.putresponseetherminetodatabase(response); } and check result of this:
log.d(log_tag, "test. after adding database. list of responses database: "); responseethermine> list = databasehelper.getlastresponsesethermine(); for(responseethermine response : list) response.checkresponse(); as can see it's checking of data of object.
public void checkresponse(){ string log_tag = "my_log " + responseethermine.class.getsimplename(); log.d(log_tag, "id = " + id + ",\n" + "address = " + address + ",\n" + "unpaid = " + unpaid + ",\n" + "settings = " + settings + ",\n" + "hashrate = " + hashrate + ",\n" + "avghashrate = " + avghashrate + ",\n" + "workers = " + workers + ",\n" + "rounds = " + rounds + ",\n" + "minerstats = " + minerstats); } here logs can helps understand problems.
myservice: test. before adding database responses looks like: service d/my_log responseethermine: id = null, address = 8f7ae5c3883f1079a8c3280ef97aabdd5e9a7960, unpaid = 49120026614693020, settings = com.example.denis.miningproject20.models.ethermine.settingsethermine@52e3650, hashrate = 31.9 gh/s, avghashrate = 3.1756177469135803e10, workers = com.example.denis.miningproject20.models.ethermine.workersethermine@b19b049, rounds = [com.example.denis.miningproject20.models.ethermine.roundethermine@f1c7d4e, ... service d/my_log responseethermine: id = null, address = de088812a9c5005b0dc8447b37193c9e8b67a1ff, unpaid = 0, settings = com.example.denis.miningproject20.models.ethermine.settingsethermine@2fd922b, hashrate = 25.6 gh/s, avghashrate = 2.5205229938271606e10, workers = com.example.denis.miningproject20.models.ethermine.workersethermine@c28688, rounds = [com.example.denis.miningproject20.models.ethermine.roundethermine@d00e821, ... then put responses database. , print in logs:
list<responseethermine> list = databasehelper.getlastresponsesethermine(); for(responseethermine response : list) response.checkresponse(); and logs:
service d/my_log: myservice: test. after adding database. list of responses database: service d/my_log responseethermine: id = 12, address = 8f7ae5c3883f1079a8c3280ef97aabdd5e9a7960, unpaid = 49120026614693020, settings = com.example.denis.miningproject20.models.ethermine.settingsethermine@52e3650, hashrate = 31.9 gh/s, avghashrate = 3.1756177469135803e10, workers = com.example.denis.miningproject20.models.ethermine.workersethermine@b19b049, rounds = [com.example.denis.miningproject20.models.ethermine.roundethermine@f1c7d4e,... service d/my_log responseethermine: id = 13, address = de088812a9c5005b0dc8447b37193c9e8b67a1ff, unpaid = 0, settings = com.example.denis.miningproject20.models.ethermine.settingsethermine@2fd922b, hashrate = 25.6 gh/s, avghashrate = 2.5205229938271606e10, workers = com.example.denis.miningproject20.models.ethermine.workersethermine@c28688, rounds = [com.example.denis.miningproject20.models.ethermine.roundethermine@d00e821,... at current stage, checked tables settings table, runs, workers , size 0.
logs:

log.d(log_tag, "this message lastresponsesethermine. number of last responses ethermine: " + databasehelper.getinstance().getlastresponsesethermine().size()); log.d(log_tag, "number of items in table rounds ethermine: " + databasehelper.getinstance().getlistofroundsethermine().size()); log.d(log_tag, "rounds ethermine: " + databasehelper.getinstance().getlastresponsesethermine().get(0).getrounds()); databasehelper.getinstance().getlastresponsesethermine().get(0).checkresponse(); and logs:
