Question

App正确运行并创建数据库和表，但是当我尝试保存模型时，我得到了这个例外。但是当应用崩溃时和我relunch the app时，error doesn't happen anymore！和saves and loads models very well！

在Application类上初始化activeandroid：

@Override
public void onCreate() {
    super.onCreate();
    ActiveAndroid.initialize(this);

模特课：

@Table(name = "history_records")
public class HistoryRecord extends Model {

public static final String COST = "cost";
public static final String REMOTE_ID = "remoteId";
public static final String OWNER_ID = "ownerId";
public static final String DURATION = "duration";
public static final String DATE = "date";
public static final String TO_NUMBER = "to_number";
public static final String FROM_NUMBER = "from_number";
public static final String SESSION = "session";
// Stores this record's position in tab
@Column(index = true)
public String tab;

@Column(name = COST)
@Expose
@SerializedName("cost")
public float cost;

@Column(name = REMOTE_ID, index = true)
@Expose
@SerializedName("id")
public String remoteId;

@Column(name = OWNER_ID)
@Expose
@SerializedName("owner_id")
public String ownerId;

@Column(name = SESSION)
@Expose
@SerializedName("session")
public String session;

@Column(name = FROM_NUMBER)
@Expose
@SerializedName("from")
public String from;

@Column(name = TO_NUMBER)
@Expose
@SerializedName("to")
public String to;

@Column(name = DATE)
@Expose
@SerializedName("date")
public String date;


@Column(name = DURATION)
@Expose
@SerializedName("duration")
public int duration;

@Expose
@SerializedName("track")
public List<Track> tracks;

public HistoryRecord() {
    super();
    tracks = new ArrayList<>();
}

public List<Track> getTracks() {
    return getMany(Track.class, "history_record");
}
}

这是我的保存代码：

ActiveAndroid.beginTransaction();
            try {
                for (HistoryRecord hr : records) {
                    hr.tab = tabNumber;
                    hr.save();
                    for (int i = 0, tracksSize = hr.tracks.size(); i < tracksSize; i++) {
                        hr.tracks.get(i).historyRecord = hr;
                        hr.tracks.get(i).data.track = hr.tracks.get(i);
                        hr.tracks.get(i).save();
                        hr.tracks.get(i).data.save();
                    }
                }
                ActiveAndroid.setTransactionSuccessful();
            } catch (Exception e) {

            } finally {
                ActiveAndroid.endTransaction();
            }
