Android的 - 从设备中完全删除短信和短信作出不可恢复 [英] Android - Delete SMS completely from the device and make SMS non recoverable

问题描述

我想通过我的应用程序删除所有来自移动短信。
目前，我用下面code删除消息。

I want to delete all the sms from the mobile through my application. Currently, I am deleting messages using below code.

    Uri uriSms = Uri.parse("content://sms/");
        Cursor c = getContentResolver().query(uriSms,
            new String[] { "_id", "thread_id", "address","person", "date", "body" }, null, null, null);

        if (c != null && c.moveToFirst()) {
            do {
                long id = c.getLong(0);
                getContentResolver().delete(Uri.parse("content://sms/" + id), null, null);
            } while (c.moveToNext());
        }

我能够从手机删除邮件。

但是，通过使用一些恢复应用程序，它们将被恢复。

But by using some recovery applications, they are restored.

我试图通过删除路径的文件

I tried to remove it completely by deleting the file from path

数据/数据​​/ com.android.providers.telephony /数据库/ mmssms.db

"data/data/com.android.providers.telephony/databases/mmssms.db"

但它给了我以下权限被拒绝的错误。

But it gave me following permission denied error.

12-12 00:37:29.673: W/System.err(9724): java.io.FileNotFoundException: /data/data/com.android.providers.telephony/databases/mmssms.db (Permission denied)

我怎样才能完全删除从我的设备的消息？使用一些安全的删除方法？

How can I completely remove the messages from my device? Using some secure delete method?

推荐答案

您不能删除，除非该设备是植根一个储存在另一个应用程序沙箱（如com.android.providers.telephony）的文件。

you can't remove a file that's stored on another application sandbox (as com.android.providers.telephony) unless the device is rooted.
