UDS might not work on Android10

Open ylz-at opened this issue 3 years ago • 4 comments

I tried to copy-paste the code of the UDS server part and test it on Android 10 (device: Note20 Ultra), and got the error: bind Read-only file system.

        minSdkVersion 29
        targetSdkVersion 30

Could you please try to update the demo and see if it works on API level >=29?

My bad... Yes, it works on Android10

I typed

strncpy(server_addr.sun_path, socket_name, sizeof(server_addr.sun_path) - 1);

as

strncpy(server_addr.sun_path, SOCKER_NAME, sizeof(server_addr.sun_path) - 1);

lol
