我正在使用这个DataBaseHelper.class,我被困在onUpgrade()方法上.我不知道如何弄清楚数据库的版本号是什么.我可以将版本设置为1,我第一次发布它,当我发布更新时,我只需将版本设置为2 (myDataBase.setVersion(2);).但只要应用程序正在运行,它就只有2.下一次它将被启动它再次是1.同样的事情发生了private static int DATABASE_VERSION.我正在考虑将版本号存储在一个额外的表中,但在我看来,这似乎不是最佳实践.

那么如何确保版本号在升级后增加并且保留它(分配给private static int DATABASE_VERSION或的值myDataBase.getVersion();)？

DataBaseHelper类:

public class DataBaseHelper extends SQLiteOpenHelper {

    //The Android's default system path of your application database.
    private static String DB_PATH = "/data/data/com.mydatabase.db/databases/";

    private static String DB_NAME = "database.sl3";

    private SQLiteDatabase myDataBase;

    private final Context myContext;


    // Do you need this?
    private static int DATABASE_VERSION = 2;
    // or is this correct:
    // private static int DATABASE_VERSION = myDataBase.getVersion();
