android 12以上改变应用最大32进程限制方法
Mac版本：

[Bash shell] 纯文本查看 复制代码

#查看当前系统最大进程数
adb shell dumpsys activity settings | grep max_phantom_processes
如果没改变则为32，只有Android12有效果
 
 
#停用
adb shell device_config set_sync_disabled_for_tests persistent 
#设定最大数是65536
adb shell device_config put activity_manager max_phantom_processes 65536
 
#这时再调用下面的，就变为65536了
adb shell dumpsys activity settings | grep max_phantom_processes

Windows版本：

[Bash shell] 纯文本查看 复制代码

#查看当前系统最大进程数
adb shell dumpsys activity settings | findstr max_phantom_processes
如果没改变则为32，只有Android12有效果
> max_phantom_processes=32

#停用
adb shell device_config set_sync_disabled_for_tests persistent
#设定最大数是65536
adb shell device_config put activity_manager max_phantom_processes 65536

#这时再调用下面的，就变为65536了
adb shell dumpsys activity settings | grep max_phantom_processes
