Avoid rewrites in tmp

[lollita]

If I have understood correctly, scrcpy, every time it runs, it writes scrcpy-server.odex and scrcpy-server.vdex in /data/local/tmp.
Do it is possible to avoid all these rewrites, and keep the file by overwriting it if not exist or there is a new one?

See #1722.

Why is it a problem for you?

[lollita]

I think it's unnecessary wear and tear on the memory card if avoidable.
I subscribe #1722.

Maybe make an apk package for the scrcpy-server?

[lollita]

I use
chmod -w /data/local/tmp/oat/arm64/scrcpy-server.*
Until the new version.

If user has concern about this, the best way is to create an apk and install it. However, it may need to do something to make server as apk. In short time, maybe we can remain the server in device and calculate the checksum to ensure the server in device is expected.

For information, I started to work on a new option (probably --install) which would install the server (if the same version is not already installed) instead of pushing it (the same way I do for gnirehtet). As a side effect, this will solve this issue.

The goal is to install a real Android app. This will pave the way to:

• provide an IME (to inject non-ASCII text)
• forward audio (a proper integration of what sndcpy does)
• optionally mirror camera instead of the screen (which requires a user authorization from an app)
• …

I am excited about this, things like #1484 can also be solved by provding apk. For example, we can add a notification or toast directly on phone.

@rom1v how about progress of scrcpy's IME?

[rom1v]

Unfortunately, no. For now, I'm working on #40 to add asynchronous swscale, and I'm doing more refactors (so that in the end I will be able to split the core from the UI).

Also related, as an alternative, maybe #2130 could allow proper text injection (I don't know).

[quyleanh]

Thank you. I hope the IME can be implemented soon.

Please check #3517.

I replaced "scrcpy-server" with a 0 size file.
It seems that it does not write the file but I get "scrcpy-server: 1 file pushed, 0 skipped."
Why?
