Today

• Quick start on emulator– And how to run on device

• Structure of the build process and artifacts• Packaging for app store• Troubleshooting / debugging• Support channels and further questions

QUICK START

29.03.14 @AgileArtemhttp://www.codingsubmarine.com

Preparing SDK1. Get Python (project renaming script will need it)2. Install SDK https://sailfishos.org/develop.html3. Run its Updater ( Help -> Start Updater)4. Get HelloWorld Pro from

https://github.com/amarchen/helloworld-pro-sailfish and open it (you need a project for Updating part of SDK)– Configure for all available platforms

5. Rename project into harbour-my-great-app via rename-to-my-project.py

6. Start Mer build machine (can take a couple of clicks)

7. Install more updates via Sailfish OS tab

Starting app on emulator

• Set i486 platform as active

• Deploy as RPM

• Run subproject src

29.03.14

Start emulator and app

29.03.14

Running tests on emulator

• Run /usr/share/tst-harbour-my-great-app/runTestsOnDevice.sh– As README.md says

Connecting device• https://sailfishos.org/develop-firstapp-article.html covers it well

– Works fine on WiFi– Couldn’t make it work via USB

29.03.14

Then run on device• Same as on

emulator• Just don’t

forget to select armv7 platform

29.03.14

Continue in QML

STRUCTURE OF THE BUILD PROCESS

29.03.14 @AgileArtemhttp://www.codingsubmarine.com

Project directories

Building-packaging

29.03.14 @AgileArtemhttp://www.codingsubmarine.com

PACKAGING FOR APP STORE

29.03.14 @AgileArtemhttp://www.codingsubmarine.com

Build RPM package

1. Choose ARMV7 platform

2. *Clean* not to package i486 binaries

3. Deploy RPM

Validate

Submit to harbour

• http://harbour.jolla.com• Icon templates can be found at

https://sailfishos.org/apps_icons.html– As mentioned in README.md

• You’ll need screenshots– Use Screenshot or SailshotMe app on device– Upload to Dropbox via Sailbox app

29.03.14 @AgileArtemhttp://www.codingsubmarine.com

TROUBLESHOOTING DEPLOYMENTS

29.03.14 @AgileArtemhttp://www.codingsubmarine.com

Troubleshooting failed deployments and not runnable apps

• Examine the content of the Mer machine and emulator directories. And device too if you need

• Is covered well at https://sailfishos.org/develop-faq.html

• Mer: ssh -p 2222 -i ~/SailfishOS/vmshare/ssh/private_keys/engine/root root@localhost

• Emulator: ssh -p 2223 -i ~/SailfishOS/vmshare/ssh/private_keys/SailfishOS_Emulator/root root@localhost

• Real device: ssh nemo@192.168.1.38 – Address and password from the Developer Settings on device

29.03.14 @AgileArtemhttp://www.codingsubmarine.com

Debugging

• C++ debugging doesn’t work from IDE• If you comfortable with GDB, it is supposed to

work• Rumors tell that QML debugging does– I failed to get it working

• Use logging• Use automated tests

29.03.14 @AgileArtemhttp://www.codingsubmarine.com

Getting support and further questions

• IRC: #sailfishos on freenode (irc.freenode.net)

• devel-subscribe@lists.sailfishos.org

• This slideset – http://www.codingsubmarine.com/tag/class/@AgileArtem on twitter

Artem needs help

• I want to make a Telegram client, help me understand what the biz model for it could be like– And for a collaboration of several authors?

• Push @JollaHQ to communicate more about business opportunities for small devs

• Contribute to HelloWorld Pro, Log4Qt Demo• Try my apps in Jolla app store and review them
