旧答案 这段代码在源代码中

OLD ANSWER This code in the source

boolean isDevelopment =
            ((bp.protectionLevel&PermissionInfo.PROTECTION_FLAG_DEVELOPMENT) != 0);

不检查您的应用程序是否处于开发模式.它检查您请求的权限是否将protectionLevel属性(在清单中设置)设置为development. 而且，您试图获得的许可似乎没有在清单中声明任何可以通过此检查的元素:

doesn't check if your app is in development mode. It checks if the permission you are requesting has the protectionLevel attribute (set in manifest) set to development. And the permission you are trying to get seems not to have any elements declared in the manifest that could pass this check:

if (!isNormal && !isDangerous && !isDevelopment) {
        throw new SecurityException("Permission " + bp.name
                + " is not a changeable permission type");
    }

只是在获得另一许可的情况下偶然发现了这一点.似乎没有办法得到它.

Just stumbled upon this with another permission. Seems there's sadly no way to get it.
