@bodow Thanks for the advice. The following approach works:

sudo su
cp contacts.vcf /home/phablet/anbox-data/data/media/0/contacts.vcf

I resume. The system integration of Anbox seems to be very limited. The apps are shown in the app scope and the apps have hardware access with network and storage. I think, that's it.

It's possible to copy files with adb shell, but this is not for an average consumer.

It seems there is not service or data sharing. I haven't tested notifications, yet.

@bodow Thanks for the clear advice. Unfortunately I'm struggling with accessing the storage for Anbox.

I tried to copy my address-book to the Anbox container:

adb push contacts.vcf /home/phablet/anbox-data/data/media/0/
adb: error: failed to copy 'contacts.vcf' to '/home/phablet/anbox-data/data/media/0/': remote Permission denied
contacts.vcf: 0 files pushed. 142.5 MB/s (720808 bytes in 0.005s)

I also can't access the media directory. I only can list the content of the data directory, but I can't switch to a subordinated directory.

phablet@ubuntu-phablet:~/anbox-data/data$ 

I have a similar problem if I use the file manage on the device. But I also tried an adb push command within the device without success.

phablet@ubuntu-phablet:~/Downloads$ adb push contacts.vcf /data/sdcard/Download
failed to copy 'contacts.vcf' to '/data/sdcard/Download': secure_mkdirs failed: Permission denied

Some idea?

@bhdouglass Thanks. For any reasons. It works now. Maybe my vm had lost the network connection. The job started with a download:

clickable desktop
Using docker container "clickable/ubuntu-sdk:16.04-amd64"
Unable to find image 'clickable/ubuntu-sdk:16.04-amd64' locally
16.04-amd64: Pulling from clickable/ubuntu-sdk

Thanks for your help!!

Unfortunately I need additional help. I have created a simple hello world project with clickable init and a template for a python and QML app.

clickable desktop
Asking for root to start docker
[sudo] password for marc: 
Asking for root to start docker
Command '[b'docker', b'ps']' returned non-zero exit status 1.

I had installed docker with sudo apt-get install docker.io after sudo apt-get install dockerfailed. Maybe docker was not correctly installed or setup. However I can use the docker command:

docker --version
Docker version 18.06.1-ce, build e68fc7a

I know from professional projects, that docker is an own science. Therefore I hoped, that clickable manages the required docker container.

@dobey Maybe the Mirabook, but this requires the full stack implementation of USB-C on the hardware side. I think, they won't support Miracast, yet.

@dobey Thanks for your response. Even if I disconnect the bluetooth keyboard and use the FP2 as a touchpad, the mouse pointer reacts with a signbificant delay. I will re-test the scenario with a Superbook over USB-OTG, that I have ordered, but I'm afraid, that the screen will just be mirrored and not scaled.

@ellypsis Thank your for your helpful post. The problem was probably, that didn't add default at the end of the URL, because I expected, that the synchronisation retrieves the available calendars and contacts. I never add the name of the addressbook or calender in system settings of any OS.

I have tested the updated script successfully. But I had to restart the phone and remove the created database and start the script again. For any reasons.

I tested the convergence use case with an external screen, that is connected with a dongle, that uses Miracast over WiFi. In addition I tested the setup with and without a bluetooth keyboard with touchpad.

I could manage to morror the sceen in a large desktop resulution. Unfortunately the screen ratio of the vidio signal (16:10') didn't match the ratio of the external screen (16:9). The vido signal was cropped.

Further more I realised, that hte mouse respectively touch pad signals are processed with a sginificant delay. So it is allmost impossible to control the external display. I also wasn't able to activate the window mode with the tweak app.

I think, it is not an issue of the hardware. My UBports developer device is Fairpgone 2. I compared the setup with LineageOS on a weak Wileyfox Swift developer device. The external screen with Sentio and LeenaOS are very smooth and the mouse pointer response has no realizable delay.

How can I improve the performace of the convergence use case. Only with the delay, the tested setup is not usable for practice.

Shouild I test a secenrio with a wired connection? Unfortunately the FP2 has USB-B and not the full implemented USB-C to connect an external screen with HDMI. Some recommendations and experiences?

@dobey How can I install a package like clickable in the container? I think the container has its own system environment. I think I have to call the following commands:

adb shell
libertine-container-manager exec -i CONTAINER-IDENTIFIER -c "/bin/bash"

Then i can use the commands for installing clickable:

pip3 install git+https://gitlab.com/clickable/clickable.git

Unforutnately my system logs the following errors after the second command:

groups: cannot find name for group ID 1001
groups: cannot find name for group ID 1002
groups: cannot find name for group ID 1003
groups: cannot find name for group ID 1004
groups: cannot find name for group ID 1005
groups: cannot find name for group ID 1013
groups: cannot find name for group ID 1015
groups: cannot find name for group ID 1021
groups: cannot find name for group ID 2001

groups: cannot find name for group ID 3003
groups: cannot find name for group ID 3004
groups: cannot find name for group ID 9997
groups: cannot find name for group ID 32011

But I get another shell. I think, I'm in the shell of the container:

itot@ubuntu-phablet:/# 

The pip3 command is not known, so I tried the approach for Ubuntu as describedin the documentation (without sudo, because I'm already logged as root. This seem to work.

Now I will try to find an apprproate IDE. Some idea? I'll try to install "qtcreator" after the installation of Atom failed.

@cibersheep Thanks. Very precise and helpful answer! I appreciate the lively UBports community.
