Copy from mobile to compute doesn't work #1606

SunicYosen · 2020-07-20T02:57:29Z

I have searched in existing issues.
I have read the FAQ.

Environment

OS: Ubuntu20.04
scrcpy version: 1.14
installation method: Manual Build with prebuild server
device model: Xiaomi 4 Cancro
Android version: 10

Describe the bug
Copy from mobile to compute doesn't work. I copy texts with long press on mobile device, while nothing copied when I would like to paste to compute with Ctrl+v.

On errors, please provide the output of the console (and adb logcat if relevant).

What should i do?

rom1v · 2020-07-20T07:40:53Z

What is the result of adb shell id?

rom1v · 2020-07-20T07:45:17Z

The ROM is probably modified by the vendor and shell has no rights to read clioboards 😕

SunicYosen · 2020-07-20T08:11:25Z

What is the result of adb shell id?

uid=0(root) gid=0(root) groups=0(root),1004(input),1007(log),1011(adb),1015(sdcard_rw),1028(sdcard_r),3001(net_bt_admin),3002(net_bt),3003(inet),3006(net_bw_stats),3009(readproc),3011(uhid) context=u:r:su:s0

SunicYosen · 2020-07-20T08:12:57Z

shell has no rights to

And is there any ways to make the shell have rights to read clipboard?

SunicYosen · 2020-07-20T08:23:32Z

And after i change the parameters in /system/default.prop

ro.secure=0
ro.adb.secure=0

To:

ro.secure=1
ro.adb.secure=1

The adb shell would not get root by default. And the return info of adb shell id is:

uid=2000(shell) gid=2000(shell) groups=2000(shell),1004(input),1007(log),1011(adb),1015(sdcard_rw),1028(sdcard_r),3001(net_bt_admin),3002(net_bt),3003(inet),3006(net_bw_stats),3009(readproc),3011(uhid) context=u:r:shell:s0

And the copy function works well.

However, the same uid=2000, why the later have the rights to read clipboard?

rom1v · 2020-07-20T08:43:20Z

I guess the package name must match the user id.

Maybe try keep user id 0 and change the package name ("root", null...):

scrcpy/server/src/main/java/com/genymobile/scrcpy/wrappers/ServiceManager.java

Line 12 in 5086e7b

public static final String PACKAGE_NAME = "com.android.shell";

I have no idea to change the package name in code.

After change to

    public static final String PACKAGE_NAME = null;

, no response when copy text on mobile.

And I dont know the name of "com.android.shell" in root model.

Using rooted LineageOS device, I have the same issue:

Meet this problem when testing my implementation, it prints INFO: Device clipboard copied but the clipboard is always empty (len of DEVICE_MSG_TYPE_CLIPBOARD message is 0)

OS: macOS 11.6
scrcpy version: 1.21
installation method: homebrew
device model: Xiaomi Mi 11
Android version: 11

Found this from logcat

I ClipboardServiceI: MIUILOG- Permission Denied when system app read clipboard, caller 2000

This reminded me that MIUI has a privacy protection feature that prevents apps from reading clipboard (In Settings -> Privacy protection -> Protection tab -> Privacy protection lab -> Protect clipboard)

If I turned it off, clipboard synchronization will work.

It doesn't show any notifications when Scrcpy tries to read the clipboard, just returns empty string. Maybe it only handles "real" Android Apps, not sure if it's possible to workaround it.

Ran adb as non-root can fix this issues.

adb unroot
Then run scrcpy
Scrcpy
now you can copy text from phone, get:
INFO: Device clipboard copied

DRSDavidSoft · 2023-10-13T13:54:10Z

@rom1v If the shell has root access, can't it grant the required permissions to itself?
