Smartphones are more powerful then ever, with processors rivaling old laptops. So let’s try to use them like a laptop to develop web-applications on the go. This repository is a demo to show you how to do use run and develop a CAP Java Spring Boot application on your smartphone with SapMachine and how to run VSCode locally to develop and modify it. This, of course, works only on Android phones, as they are a Linux at their core.
This demo consists of a modified cap-sflight sample application (original) that can be built directly on device and a VSCode plugin to simplify running the demo.
This demo is a highly experimental prototype, used only for show-casing the ability of modern technology.
For this demo, you need an Android phone with the Termux app installed.
The setup for this demo does neither require root on your smartphone, nor the use of the developer mode.
Launch the Termux app and set up an emulated Ubuntu environment:
pkg install proot-distro
proot-distro install ubuntu
proot-distro login ubuntuClone this repository in the Ubuntu shell:
apt update
apt install git wget
git clone https://github.com/SAP-samples/demo-cap-in-the-pocket
cd demo-cap-in-the-pocketInstall SapMachine and VSCode either by running the ./install.sh script or by running:
# Install SapMachine
wget -qO- https://dist.sapmachine.io/debian/sapmachine.key | tee /etc/apt/trusted.gpg.d/sapmachine.asc > /dev/null
echo "deb https://dist.sapmachine.io/debian/$(dpkg --print-architecture)/ ./" | tee /etc/apt/sources.list.d/sapmachine.list > /dev/null
apt update -y
apt install -y sapmachine-21-jdk
# Install VSCode
wget 'https://code.visualstudio.com/sha/download?build=stable&os=linux-deb-arm64' -O code.deb
apt install -y ./code.deb
# Install the missing packages
apt -y --fix-broken install
rm code.deb
# Install the VSCode plugin
wget https://github.com/parttimenerd/cap-in-the-pocket-extension/releases/download/snapshot/cap-in-the-pocket-0.0.1.vsix .
code --install-extension cap-in-the-pocket-0.0.1.vsix --no-sandbox --user-data-dir ~For more background information, visit mostlynerdless.de.
Now you can now run VSCode at port 8080 either by running ./vscode.sh script or by running:
nohup code serve-web --port 8080 --without-connection-token &And access it in the browser at localhost:8080.
Use the VSCode plugin to build and run the CAP SFlight application.
