首次安装应用程序时，会议室数据库异常

Question

我开发了一个Android应用并使用了会议室数据库。 U首次安装该应用程序时，该应用程序将崩溃，并且例外情况是

Fatal Exception: android.database.sqlite.SQLiteException
index index_LocationHistoryBean_address already exists (code 1): , while compiling: CREATE INDEX `index_LocationHistoryBean_address` ON `LocationHistoryBean` (`address`)

我的dao文件是

@Entity(indices = {@Index("address") , @Index("title")})
public class LocationHistoryBean extends BaseObservable implements Parcelable {
    @PrimaryKey(autoGenerate = true)
    private int id;
    private String address;

    private double longitude;
    private Date cacheDate;
    private String icon;
    private String title;
    private boolean inTrafficZone;
    private boolean inOddEvenZone;
    private String category;
    private Boolean isHistory = false;

    public LocationHistoryBean() {
    }
