        Hydrogen.getInstance()
                .setDebug(BuildConfig.DEBUG)
                .setmDbName("simple.db")
                .setCursorFactory(null)

                .addModel(UserModel.class)
                .create(this);
    }

    @Override
    public void onTerminate() {
        super.onTerminate();
        Hydrogen.getInstance().terminate();
    }
}

```

UserModel user = new UserModel("张三","20");
user.save();
```
