You can call "am" with "unchroot" command:

export BOOTCLASSPATH=...
unchoot am

BOOTCLASSPATH from Android env.

This does not fit?

Example for notifications from source:

unchroot am broadcast -a ru.meefik.linuxdeploy.BROADCAST_ACTION --user 0 --es "info" "Hello World!"
unchroot am broadcast -a ru.meefik.linuxdeploy.BROADCAST_ACTION --user 0 --es "alert" "Hello World!"
unchroot am broadcast -a ru.meefik.linuxdeploy.BROADCAST_ACTION --user 0 --esn "hide"

Hi meefik!
What's the size of Ubuntu 18.04 Linux deploy?
Is it possible to download it externally?
And if I use sdcard than how much storage it'll take my memory card is 16GB and 8 GB free and it'll corrupt or delete all files on my memory card when setup ?
Or make my memory card slow?

What's the size of Ubuntu 18.04 Linux deploy?

Base system ~ 200 MB.

Can I download it externally?

You can deploy it from official repository by "deploy" command or Install from app. Or use repository in LD app.

And if I use sdcard than how much storage it'll take my memory card is 16GB and 8 GB free and it'll corrupt or delete all files on my memory card when setup ?

Use installation type - "file". LD store all container data in one IMG file and other files on sdcard will not be changed.

Is it possible to run a Windows x86 application on it through wine?
And after extraction what's the size?
You haven't answered!
That this'll make my sdcard slow of read/write speed?
Which one you consider to install on my Phone storage 64GB and 55GB free and sdcard 8GB ?
This's not going to harm my read/write speed?
Sorry , newbie here want to run x86 app through wine in LD!

Is it possible to run a Windows x86 application on it through wine?

Yes, but only on x86 device. Or on ARM with architecture emulation (binfmt_misc support is required).

And after extraction what's the size?

Base system Ubuntu ~ 300-500 MB after install.

That this'll make my sdcard slow of read/write speed?
This's not going to harm my read/write speed?

No, but depends on the applications you are running in LD.

How to get support for binfmt_misc ?
I ahve Redmi Note 4 Mido 4/64GB

How to get support for binfmt_misc ?

Check support in App: Menu -> Status -> Support binfmt_misc
From CLI: linuxdeploy status -> Support binfmt_misc
From shell: test -d /proc/sys/fs/binfmt_misc && echo yes || echo no

If your Linux kernel is not support binfmt_misc, then you can be build custom kernel or kernel module for your device. Unfortunately, you need to have the kernel sources for your device.

Meefik dude!

Here kernel sources and config I'm currently on!
Can you describe what to do now?
https://github.com/Adesh15/android_kernel_xiaomi_msm8953/blob/treble/arch/arm64/configs/mido_defconfig

You must be enable CONFIG_BINFMT_MISC as module in the config:

CONFIG_BINFMT_MISC=m

And build the module by the guide.

@meefik I'm going to run ida pro in LD how much space it's going to take?
And direct link to 18.04 LTS image please
