Giving sndcpy.apk PROJECT_MEDIA permission to bypass the prompt to allow screen recording.

[Practicalbutterfly5]

adb shell appops set com.rom1v.sndcpy PROJECT_MEDIA allow can be used to bypass the Start Recording dialog. Another thing I noticed with it was that, I needed to insert a sleep 1 command before the last vlc command so that the MainActivity gets enough time to start.

Can this be implemented?

Wow, great 👍

I implemented it on master: 026326b

Please test 😉

Even if I did not plan to do any other release of sndcpy (it's just a PoC), I'll do an exception for this I think :)

I used android studio to compile the sndcpy apk. However on compiling it with targetSdkVersion 31 and compileSdkVersion 31 the app crashes when MainActivity is launched on android 12. It works fine on android 10. Here is the logcat.
