如何将我的j2me应用程序的权限设置为“始终允许"在S40设备上? [英] How to set permissions of my j2me app to "Always allowed" on S40 devices?

问题描述

我在j2me中创建了一个应用程序，可以在诺基亚N8，C7和其他高端设备上正常运行.现在，我试图将同一个应用程序移植到低端设备S40设备(例如诺基亚5130)上播放音乐.每次我的应用程序运行时，它都会询问:您是否希望该应用程序读取用户数据?".即使在应用程序访问->数据访问->读取用户数据中，也只有两个选项处于活动状态-

I have created an app in j2me, which runs fine with Nokia N8, C7 and other high-end devices. Now i am trying to port the same app to low-end devices S40 devices such as nokia 5130 express music. Every time my app runs, it asks, "Do you want the app to read user data?". Even in the application access -> Data access -> Read user data, only two options are active-

1. Ask every time and
2. Not allowed

和其他两个选项

3. Ask first time only and
4. Always allowed

始终处于非活动状态. 我该怎么做才能使这些选项生效?

are always inactive. What shall i do to make these options active?

推荐答案

即使您要对应用程序进行签名，也不能保证始终允许"正常运行，因为存在4个安全域:

Even if you will sign your app it doesn't guarantee that "Always allowed" will work, since there are 4 security domains:

1. 第三方保护域(不受信任的第三方)
2. 已标识的第三方保护域(受信任的第三方)
3. 操作员保护域
4. 制造商保护域

如果您不是像Verizon这样的运营商，也不是像诺基亚这样的制造商，那么您的最大域名是2nd，您可以查看并比较您可以使用此域名对S40进行的操作-

If you're not operator like Verizon or manufacturer like Nokia, your maximum domain is 2nd and you can see and compare what you can do with this domain for S40 - look here

切换到Android或iPhone :) J2ME是过时的技术，请不要浪费时间.

Switch to Android or iPhone :) J2ME is outdated technology, don't waste your time.
