Version
1.0.14

Apk Downloads
You can download the latest package on the download section at My Tracks project home.

Source Code
First Create your own clone

Create a clone of the mytracks repository hosted at Google Code.

A repository clone is a server-side copy of a project’s repository and can be created by anyone that wants to contribute to a project. For more information, see the Mercurial FAQ.

Then use the Command-line access:

Get a local copy of the mytracks repository with this command:
hg clone https://mytracks.googlecode.com/hg/ mytracks

Version control Overview

My Tracks uses Mercurial, a distributed version control system. What this means is that, even though this page hosts a central repository, there can be many clone repositories with changes of their own, and then some of those can be merged back into the main repository.

The model we’ve chosen for developing My Tracks is the following:

1. Each developer creates an google code hosting clone of the main mytracks repository. This clone is hosted on Google servers.
2. The developer then makes a local clone of his code hosting clone, which is then at his local machine.
3. The developer writes new code into his local clone and commits it locally
4. When a change is ready to be integrated back into the main repository, that change is pushed from the developer’s local clone to his code hosting clone
5. He then requests a code review by opening a new issue under “Issues” above, saying which clone has the code to be reviewed, what it’s supposed to do, and what are the relevant changesets
6. The code will be reviewed on the user’s clone – if any further changes are suggested, the process repeats from (3)
7. Once the change is approved, a member of the My Tracks team will merge it back into the main repository

Even though this may sound complicated, this process makes code reviews easy and allows a lot of people to work on changes in parallel.

Keynote Day 2 Android Demo from Google I/O 2010 (Full Length)

This is the full length Android Demo video(Youtube) from keynote day 2 at Google I/O, a cute android video where you can learn all of the details about Android 2.2 with funny from Vic Gundotra, Google vice president of developer platforms.

If you can see this, then you might need a Flash Player upgrade or you need to install Flash Player if it's missing. Get Flash Player from Adobe.

According offical android developers blog, the following five areas about android 2.2 are highlighted in particular:

Performance & speed: The new Dalvik JIT compiler in Android 2.2 delivers between a 2-5X performance improvement in CPU-bound code vs. Android 2.1 according to various benchmarks.

New enterprise capabilities: We’ve added Exchange capabilities such as account auto-discovery and calendar sync. Device policy management APIs allow developers to write applications that can control security features of the device such as the remote wipe, minimum password, lockscreen timeout etc.

Faster, more powerful browser: We have brought the V8 JavaScript engine to the Android browser as part of 2.2. This has resulted in a 2-3X improvement in JavaScript performance vs. 2.1.

Rich set of new APIs and services: New data backup APIs enable apps to participate in data backup and restore, allowing an application’s last data to be restored when installed on a new or a reset device. Apps can utilize Android Cloud to Device Messaging to enable mobile alert, send to phone, and two-way push sync functionality. Developers can now declare whether their app should be installed on internal memory or an SD card. They can also let the system automatically determine the install location. On the native side, a new API now gives access to Skia bitmaps.

Additions to Android Market: Android Market provides Android Application Error Reports, a new bug reporting feature, giving developers access to crash and freeze reports from users. Developers will be able to access these reports via their account on the Android Market publisher website.

Google Android in Linux Foundation Collaboration Summit

As open source smartphone platform, Google Android’s kernel code was removed from the 2.6.33 Linux code base by the Linux Kernel community in last December has been widely discussed. Now the 4th Annual Linux Foundation Collaboration Summit is holding in San Francisco, and Google has apparently broached the topic of bringing Android back to the Linux kernel.

Google open source programs manager Chris DiBona told that Google will hire two Android coders to work with kernel.org according ZDNet’s Paula Rooney and acknowledged that Google needs to do a “better job” of contributing Android patches back to the Linux kernel.

Developers from Google’s Android team are due to meet the Linux kernel devs in the Linux Foundation Collaboration Summit and Linux Foundation executive director Jim Zemlin said: “I think they can hopefully work it out… the purpose of this event is to table those conversations.”

The reintegration would not be too hard because Google has deliberately stuck very close to the main Linux kernel with Android, but DiBona noted that it would be a “multi-year” process at the same time.

About Linux Foundation Collaboration Summit
The Linux Foundation Collaboration Summit is an exclusive, invitation-only summit gathering core kernel developers, distribution maintainers, ISVs, end users, system vendors and other community organizations for plenary sessions and workgroup meetings to meet face-to-face to tackle and solve the most pressing issues facing Linux today

This acquisition shows that Google thinking highly of the visual search engine.

“Google has already shown that it’s serious about investing in this space with Google Goggles, and for the Plink team the opportunity to take our algorithms to Google-scale was just too exciting to pass up”, said by Plink founder in their blog. “We’re looking forward to helping the Goggles team build a visual search engine that works not just for paintings or book covers, but for everything you see around you.” So we have a reason to believe a better “Plink Art” App will be available in the near future.

About Plink
Plink makes visual search engines that let you find out more about something just by taking a photo of it.

About Plink Art
