鸿蒙5.0无法正常使用aidlux

[Luosury]

在正常授权后且初始化后直接变成终端

而且除了光标没有其他任何东西，如图

[gakuson]

只是没装桌面吧，试一下
sudo aid-pkg -i aid-desktop

[XU13241ae]

请问具体应该怎么操作

[Aid_1664790971649]

执行命令 sudo aid-pkg -i aid-desktop

[XU13241ae]

请问应该怎么执行命令，回车键是换行，esc同样没有反应。

所给出的图片中反馈了你的aidlux没有初始化成功，鸿蒙越往后对Android兼容越差；
请尝试 清了AidLux数据,然后用adb取消了虚进程限制再试下，可根据帖子：https://forum.aidlux.com/t/topic/71958；
（鸿蒙5.0能不能用adb也需要试一下）

[阿加犀官方发布]

详情同上

总结

只想快速解决此问题, 就不用查看后续章节, 只需要执行以下命令:

• root 设备, 用su执行:

su -c "/system/bin/device_config put activity_manager max_phantom_processes 2147483647"
su -c "/system/bin/device_config set_sync_disabled_for_tests persistent"

• 非 root 设备, 用adb执行:

adb shell "/system/bin/device_config put activity_manager max_phantom_processes 2147483647"
adb shell "/system/bin/device_config set_sync_disabled_for_tests persistent"

adb的使用请查看ADB 使用教程

原因

Android 12 via 15755084 和更新 5706277f 增加了一种机制来监视应用程序启动的分支子进程( 以下称虚进程 ),如果发现其运行的数量超过默认的 32 ( 针对所有应用程序启动的分支子进程之和 ),则杀死它们.

如果应用程序或虚进程使用过多的 CPU, 它们也可能被杀死, 以前也是这样的, 但仅限于应用程序进程本身.

HarmonyOS 3 使用的 Android 版本提升到了 12, 所以也引入了此特性.

检查

检查允许运行的最大虚进程

• root``su -c "/system/bin/dumpsys activity settings | grep max_phantom_processes"
• adb``adb shell "/system/bin/dumpsys activity settings | grep max_phantom_processes"

执行结果:

$ adb shell "/system/bin/dumpsys activity settings | grep max_phantom_processes"
  max_phantom_processes=32

检查被监视运行的虚进程

• root``su -c "/system/bin/dumpsys activity processes -a"
• adb``adb shell "/system/bin/dumpsys activity processes -a"

执行结果:

$ adb shell "/system/bin/dumpsys activity processes -a"
...
  All Active App Child Processes:
    proc #0: PhantomProcessRecord {8f40e4b 18733:18405:bash/u0a236}
      user #0 uid=10236 pid=18733 ppid=18405 knownSince=-11m52s638ms killed=false
      lastCpuTime=0 oom adj=-1000 seq=82
    proc #1: PhantomProcessRecord {5472028 19126:18405:bash/u0a236}
      user #0 uid=10236 pid=19126 ppid=18405 knownSince=-11m52s638ms killed=false
      lastCpuTime=0 oom adj=-1000 seq=82
    proc #2: PhantomProcessRecord {2051141 19128:18405:python2/u0a236}
      user #0 uid=10236 pid=19128 ppid=18405 knownSince=-11m52s638ms killed=false
      lastCpuTime=50 timeUsed=+450ms oom adj=-1000 seq=82
    ...
...

如果没有这部分信息, 拔插电源触发一个更新, 然后再查看.

检测被杀死的虚进程

当你检测到虚进程被杀死, 执行adb命令:

adb logcat -d -e '^Killing PhantomProcessRecord'

执行结果:

$ adb logcat -d -e '^Killing PhantomProcessRecord'
--------- beginning of system
03-21 14:59:47.660  1033  1377 I ActivityManager: Killing PhantomProcessRecord {8f40e4b 18733:18405:bash/u0a236}: Trimming phantom processes

...

手动触发杀死虚进程

如果想进行一次测试体验虚进程被杀死的过程, 可按以下流程执行

1. 启动 AidLux, 查看当前运行的进程:

root@localhost:/home# ps -ef

2. 使用adb检查当前被监视运行的虚进程:

$ adb shell "/system/bin/dumpsys activity processes -a"

...

一共有16个虚进程
3. 使用adb确认允许运行的最大虚进程:

$ adb shell "/system/bin/dumpsys activity settings | grep max_phantom_processes"
max_phantom_processes=32

4. 在 AidLux 的 terminal 中运行 30 个sha256sum进程:

root@localhost:/home# for i in $(seq 30); do sha256sum /dev/zero & done
[1] 19196
[2] 19197
[3] 19198
[4] 19199
[5] 19200
[6] 19201
[7] 19202
[8] 19203
[9] 19204
[10] 19205
[11] 19206
[12] 19207
[13] 19208
[14] 19209
[15] 19210
[16] 19211
[17] 19212
[18] 19213
[19] 19214
[20] 19215
[21] 19216
[22] 19217
[23] 19218
[24] 19219
[25] 19220
[26] 19221
[27] 19222
[28] 19223
[29] 19224
[30] 19225

现在就有16+30=46个虚进程
5. 将 AidLux 置于后台, 连接或断开电源, 返回 AidLux 查看, 现在会显示:

root@localhost:/home# [Process completed (signal 9) - press Enter]

6. 再次使用adb检查当前被监视运行的虚进程:

$ adb shell "/system/bin/dumpsys activity processes -a"

杀掉了14个虚进程, 46-32=14 , 验证逻辑正确.

解决

禁用杀死虚进程

根据源代码中的trimPhantomProcessesIfNecessary() for循环, 将max_phantom_processes设置为Integer.MAX_VALUE(2147483647), 以禁止杀死虚进程, 因为if (mService.mConstants.MAX_PHANTOM_PROCESSES < mPhantomProcesses.size())条件将总是失败

• root``su -c "/system/bin/device_config put activity_manager max_phantom_processes 2147483647"
• adb``adb shell "/system/bin/device_config put activity_manager max_phantom_processes 2147483647"

但存在以下 3 种情况可能将该值重置为默认值:

• Android 系统重启
• Android 系统崩溃
• gms 同步更新配置

可以在禁用杀死虚进程之前通过禁止设备配置同步来解决此问题

禁止设备配置同步:

• root``su -c "/system/bin/device_config set_sync_disabled_for_tests persistent"
• adb``adb shell "/system/bin/device_config set_sync_disabled_for_tests persistent"

但该设置存在系统无法从无限重启, 崩溃和错误配置值中恢复的风险!

如果没有gms服务, 我觉得没必要设置, 可以自行测试一下.

另附重新启用设备配置同步和检查设备配置同步状态方法

重新启用设备配置同步:

• root``su -c "/system/bin/device_config set_sync_disabled_for_tests none"
• adb``adb shell "/system/bin/device_config set_sync_disabled_for_tests none"

检查设备配置同步状态:

• root``su -c "/system/bin/device_config is_sync_disabled_for_tests"
• adb``adb shell "/system/bin/device_config is_sync_disabled_for_tests"

禁用杀死虚进程后进行测试, 然后检查被监视运行的虚进程:

$ adb shell "/system/bin/dumpsys activity processes -a"

一共46个虚进程全部存活

Android 12L 或 Android 13

添加设置切换虚进程监视在开发选项的新补丁已经被合并到了Android 12L的AOSP中,使用Android 12L或Android 13的设备可以依据此特性解决此问题.

经验证, 该特性虽然已经被合并, 但是在生产设备中该功能菜单并未显示, 所以只能通过标识符去关闭:

adb shell settings put global settings_enable_monitor_phantom_procs false

其他

• adb
• scrcpy 这里推荐一个开源软件, 其自带 adb 依赖, 提供了显示和控制通过 USB (或通过 TCP/IP) 连接的 Android 设备的功能, 不需要 root, 无侵入性, 秒连.
