我在 Android 10 上连接 VPN 并在 logcat 中收到以下消息时遇到问题。这是权限错误。寻找解决方案。还在 Mainfest 中添加了 android:requestLegacyExternalStorage="true" 但对我不起作用。

D/ConnectionStatus：IO Exceptionjava.io.IOException：无法运行程序“/data/user/0/com.casvpnapp/cache/pie_openvpn.x86_64”：error=13，权限被拒绝

我想在我的 Android Studio 项目中导入以下库，这些库位于/system/lib64/ 文件夹中。 我得到以下错误

上线System.loadLibrary("strongswan")

        System.loadLibrary("strongswan");

        if (MainActivity.USE_BYOD)
        {
            System.loadLibrary("tncif");
            System.loadLibrary("tnccs");
            System.loadLibrary("imcv");
        }

        System.loadLibrary("hydra");
        System.loadLibrary("charon");
        System.loadLibrary("ipsec");
        System.loadLibrary("androidbridge"); …
