Fix permission denial error after Android upgrade

Fixed by 5b51396.

Here is a binary with the fix to replace in scrcpy 3.3.3:

scrcpy-server _{SHA-256: f4387c2eccebf17dc8e40bf9e6ec61705dfce5356a32f93d8568d1a97599d11}

I tried patching build 3.3.3, but it didn't fix the error. Not sure if I did something wrong, or if I need to build from the latest commit. But it was easiest for me to patch, and build from 3.3.3. It also seems like a small change that should fix it.

prebuilt_server : /var/tmp/portage/app-mobilephone/scrcpy-3.3.3/distdir/scrcpy-server-v3.3.3

You're only rebuilding the client, where as the change is in the server.

I'm sorry, but I don't understand what I'm failing to do. I get there's client, and server. I see there two separate binaries. But when I build scrcpy through portage, or the install_release.sh a scrcpy-server bin doesn't get built. I tried manually putting the scrcpy-server into /usr/bin also, but it didn't change anything. I apologize for my lack of understanding.

I figured it out. Sorry for the waste of time. I didn't realize I needed to replace the scrcpy-server apk that's installed at /usr/share/scrcpy. Thank you for your help.

Fixed in scrcpy 3.3.4.
