root后的保护级别
AFAIK，似乎没有任何方法可以在不 root 手机的情况下获得 ProtectionLevel=3 的许可。我到处寻找，到处都看到同样的答案：“这是不可能的。”然而，ProxyDroid 可以做到这一点，我在市场上看到的其他一些应用程序也是如此。
但是，这些应用程序需要 root 权限。所以我的问题是，root后我们可以获得这些权限吗？
我正在尝试获得 WRITE_SECURE_SETTING 的许可。但是我总是收到以下错误：
08-05 21:19:04.372: ERROR/DatabaseUtils(1117): java.lang.SecurityException: Permission denial: writing to secure settings requires android.permission.WRITE_SECURE_SETTINGS
AFAIK, there doesn't seem to be any way to get permission for ProtectionLevel=3 without rooting the phone. I have searched high and low, and everywhere I look, I see the same answer: "It can't be done." However, ProxyDroid does it, and so do some other applications that I have seen on the market.
However, these applications ask for root privileges. So my question thus is, can we get these permissions after rooting them?
I am trying to get permission for WRITE_SECURE_SETTING. However I always get the following error:
08-05 21:19:04.372: ERROR/DatabaseUtils(1117): java.lang.SecurityException: Permission denial: writing to secure settings requires android.permission.WRITE_SECURE_SETTINGS
