[Ubuntu Touch] Update to Logviewer

I am pleased to announced that Logviewer is now published in the Ubuntu Touch store.  The app no longer runs unconfined but uses “read_path” pointing to “/var/log/” and “/home/phablet/.cache/”. If you think there is another interested log path let me know and I will try to include it.

Also, one feature that landed by popular request is submitting a selected section of a log to pastebin , thanks to Popey for the image:

[Ubuntu Touch] Logviewer

I have been recently doing some android development for Techfunder, one thing that I have found really useful when testing my app is using CatLog. CatLog allows you to check the app and system logs on the go. This is extremely useful when you have a crash while you are not close to your laptop.

This motivated me to look into writing a similar app for Ubuntu Touch. So here it is: LogViewer!

logslogsettingsunitylog

This app, like CatLog, is for developers and requires unconstrained running. You will need to install it manually:

  • Download click package from launchpad
  • transfer to your device and install:
  1. adb push com.ubuntu.developer.vtuson.logviewer_0.1_armhf.click /home/phablet/
  2. adb shell

  3. su phablet
  4. cd ~
  5. pkcon -p install-local com.ubuntu.developer.vtuson.logviewer_0.2_armhf.click

When you launch the app, you will get a list of .log files in /home/phablet/.cache/upstart/ , if you click on an specific log, it will be displayed in a similar manner to tail -f. You can pause the autoreading, clear the screen and copy to clipboard parts of the logs from the bottom menu.

You can also access other files, change font size of the logs and the size of the text buffered from the settings page.

You can see the code and contribute :) in launchpad:

Developing for Android and Ubuntu – with the same phone

We announced today a new solution to dual boot Android and Ubuntu on the same device. Over the last few weeks I have recently blogged about a Contacts import app for Ubuntu and  Techfunder, an Android app for crowd funding projects. What I didn’t mention before is that I have been developing and testing both in the same device!

I have been dog-fooding and developing a small part of our dual boot solution for a couple weeks now.  During that time, I’ve not only been able to boot between Android and Ubuntu as a user, but also as an application developer.

Dual boot brings no compromise to the SDK experience of either operating system.  I run Ubuntu SDK with QTCreator and Android’s ADT (eclipse-based) on my 12.04 LTS laptop.  And while the SDK for Android is more mature and fully featured, I still find Ubuntu (an particularly QML) much faster to prototype apps.

Dual boot is also about making the application developers life easier and cheaper.  Having to buy extra devices for testing new apps can be a put you off. You can now develop for Ubuntu by jusr re-using your Android device.. without having to disrupt your android projects!  For example,  yesterday I was working on applications on both sides, and I was easily booting back and forward and collecting logs in each side.

I hope to see more integration in between both development environments, I think it will be particularly neat to have something like  Android Monitor tool (aka DDMS) working for both OSs.

Btw, I have just released version 2.0 of Techfunder! Including home screen widgets, search and more categories. Don’t forget to check it out:

[Ubuntu QML] Importing Google Contacts

I have a lot of contacts in my phone… I am sure you will have more, but syncing over 500 contacts to Ubuntu phone using the command line for Syncevolution gets tedious.

So I wrote a little QML app to do the trick for you. Unfortunately, to run a system command the application has to run unconfined, so I have not yet submitted it to the store.

But if you want to install it yourself it is pretty simple:

  1. Download this file
  2. push the downloaded file to your phone, like so: adb push com.ubuntu.developer.vtuson.contactsimporter_0.9_armhf.click /home/phablet
  3. then run this to install it: adb shell “sudo -u phablet pkcon -p install-local  /home/phablet/com.ubuntu.developer.vtuson.contactsimporter_0.9_armhf.click”

You should be good to use it now, the app looks like this: (and if you want to check out the code is here)

Ubuntu Touch: Building and testing a QML extension

Hi,

I found myself trying to build a QML Ubuntu Touch app project that includes a qml c++ extension and I found that I some how stumble a bit along the way. So, here are some of my notes on how I got it done. Hope that helps.

Creating the project.

Using QtCreator, create a new project and select – QML Extension Library + Tabbed Touch.  I found that it was easier to change the QML side of things than start with an extension and then add the whole project structure.

Build and Run your project locally

In QtCreator click on projects.  In Build, I set up the build path as my project root path. In run,  the executable is “/usr/bin/qmlscene” (make sure there is no spaces trailing) and then Arguments is set to “-I  ../backend/modules $@ yourapp.qml”, with a working directory of “projectroot/app”

Now if you try to run your project it should build it locally and run your app. After that you are on a roll.

Build on target device

Click Ctrl+f11 should install the platform developer tools in your device. However, I how found that this lately does not work.

Instead from the terminal:

first we will need to make the image in your device writeable:
adb shell touch /userdata/.writable_image  --> and reboot the phone.
then:
cd /usr/share/qtcreator/ubuntu/scripts
adb devices
./device_developertools_install <device_id>

Now you are ready to build, so back to QtCreator:

Build>Ubuntu>Build Application on Device

This should build the application with only some test problems, but the main binaries would be created. To package your app you will need to get

/home/phablet/dev_tmp/<yourapp>/backend/modules/lib<yourlib>.so

Creating a click package

create a manifest standard manifest file. Manifest.json

{
"description": "your text",
"framework": "ubuntu-sdk-13.10",
"hooks": {
"yourappname": {
"apparmor": "yourappname.json",
"desktop": "yourappname.desktop"
}
},
"maintainer": "your name<yourname@yourmail.com>",
"name": "com.ubuntu.developer.yourname.yourappname",
"title": "yourappname",
"version": "0.1",
"architecture": "armhf"
}

You will also need a yourapp.desktop file:

[Desktop Entry]
Name=yourappname
Comment=description
Exec=qmlscene -I plugin $@ yourapp.qml
Icon=icon.png
Terminal=false
Type=Application
X-Ubuntu-Touch=true

Note that Exec= has a -I plugin part to it. This is very important, will see later.

Now yourapp.json file that contains your confinement profile:

{
"policy_groups": [
"networking"
],
"policy_version": 1
}

Now time to setup a folder with all this stuff, not that the plugin folder is going to contain your lib which your are importing with -I option on the desktop file:
myproject>
-./click/
--icon.png
--manifest.json
--yourapp.json
--yourapp.desktop
--./plugin/
---./yourlib/
----lib(yourlibname).so
----qmldir

Now you are ready to build from your project root folder:
click build ./click

This should create a .click file in your project folder.

Installing in your device

adb pull your.click /home/phablet/
adb shell
su phablet
cd ~
pkcon -p install-local your.click

This should be enough, but sometimes I find that you need to restart unity:
pkill unity8 (you might need sudo)

Introducing Techfunder for Kickstarter and Indiegogo

Since I lead the Ubuntu Edge campaign, I have been trying to keep up with other crowd funding projects.  I am mainly interested on technology and gadgets, and I have found it hard to navigate Kickstarter, but also to have to keep hoping between Kickstarter and Indiegogo to see what is going on.  Specially since now, seems like interesting projects are evently split between them.  You might share my friction on this… so I give you Techfunder:

Get it on Google Play

Techfunder is an Android app that provides an easy way to browse crowd funding projects launched across the main industry websites. Techfunder gathers Technology and Design projects from Kickstarter and Indiegogo.

Using Techfunder side navigation you can easily switch between:

  •  Popular
  •  New this week
  •  Staff Picks
  •  Design – Popular

Then you can browse as many projects on a compact scrollable list. Just click on the project you are interested to expand into a full screen view.From there you can tell the world about it using the share button. 

If you want to contribute or found out more about it, click on the “browse” button and Techfunder will launch the project page in your web browser. When you are finished, just press the Android back button to return to Techfunder.

I am currently planning to add a favourites/watchlist functionality and looking into a way to select additional crowd sourcing platform. I hope you enjoy it!
