With new events, improved courses and an expanded mentorship network - Startup Launch is now Google Developers Launchpad. We’re changing our program name to emphasize how you can use our resources as a launch pad to scale and monetize your app business. Read on to learn about our upcoming events and how you can apply to participate.
Launchpad Week, Launchpad’s weeklong in-person bootcamp for early-stage apps, continues to expand, with new 2015 programs planned in Munich, Mexico City, Helsinki, Bogota, and Sydney, to name a few. We’ll also regularly host these events in Tel Aviv, London, Berlin, and Paris.
We kicked off Launchpad Week in Bengaluru, India and Bordeaux, France last month. 32 startups and 80 experts from these communities gathered at Idiom Design Center and Le Node for a week of product, UX, and technology sprints designed to help transform ideas into validated, scalable businesses.
Featured startups from Bengaluru included iReff, an app that helps pre-paid mobile users find the best recharge plan for their specific needs. In Bordeaux, Google Developer Expert David Gageot volunteered as a tech mentor, helping startups “ship early, ship often” through testing and continuous integration.
For later-stage startups, we’re providing some of the best tech experts to help optimize apps for Material Design, Android TV, and Google Cast at two-day Google Developer Summits. At an event in Buenos Aires, Argentina, last week, we had participants such as game developer Etermax, the team behind Trivia Crack. Similar events happened in Kuala Lumpur, Bangkok, and Bengaluru this month, and we’re looking forward to inviting more startups to this program in London, Tokyo, Tel Aviv, and New York in 2015.
In 2014, we helped over 5,000 developers in 170 countries get their ideas off the ground by providing the infrastructure back-end that allows developers to build incredible products. For example, our program delivered software architecture reviews and Google Cloud Platform credits to help entrepreneurs in the program build businesses that scale with them. Check out how Fansino is using Google Cloud Platform to let artists interact with their fans.
We’ve also expanded our product offer for early-stage startups to include AdWords promotional offers for new accounts. Whatever your monetization plan, we’re making it easy to get started with tools like the new In-app Billing API and instruction from the AdMob team.
Starting this month, we’ll offer a virtual curriculum of how Google products can help your startup. We’re kicking things off with new Launchpad Online videos covering Google Analytics - are you observing how your users use your app? How do different promotional channels perform?
The series continues in April 2015 with AdMob products, and will expand with instruction in implementing material design and conducting user research later in the year.
If you can’t wait, we’ve also built courses together with Udacity to take your technical skills to the next level on topics, including Android, Java, Web Fundamentals, and UX.
Apply to Google Developers Launchpad program to take advantage of these offers - g.co/launchpad. Here’s to a great launch!

As a developer, writing your app is important. But even more important is getting it into the hands of users. Ideally millions of users. To that end, you can now learn what it takes to design, validate, prototype, monetize, and market app ideas from the ground up and grow them into a scalable business with the new Tech Entrepreneur Nanodegree.
Designed by Google in partnership with Udacity, the Tech Entrepreneur Nanodegree, takes 4-7 months to complete. We have teamed up with most successful thought leaders in this space to provide students with a unique and battle-tested perspective. You’ll meet Geoffrey Moore, author of “Crossing the Chasm”, Pete Koomen, co-founder of Optimizely; Aaron Harris and Kevin Hale, Partners at Y-Combinator; Nir Eyal, author of the book “Hooked: How to build habit forming products” and co-founder of Product Hunt; Steve Chen, Co-Founder of YouTube, rapid prototyping company InVision and many more.
All of the content that make up this nanodegree is available online for free at udacity.com/google. In addition, Udacity provides paid services, including access to coaches, guidance on your project, help staying on track, career counseling, and a certificate when you complete the nanodegree.
The Tech Entrepreneur offering will consist of the following courses:
Upon completion, students will receive a joint certificate from Udacity and Google. The top graduates will also be invited to an exclusive pitch event, where they will have the opportunity to pitch their final product to venture capitalists at Google.

Google I/O 2015 starts tomorrow, and, like last year, we’ve got an exciting lineup of design-focused content for both developers and designers to experience in-person and online. Just a year ago, we announced material design - a system for cross-platform visual, motion, and interaction design. This year at I/O, we’ll see how material has been adopted and implemented by the community, and our approach on design across our platforms.
At 4PM PDT on Thursday, May 28, join Matias Duarte’s “Material Now” session to recap where we’ve been and get a sneak peek of where we’re going with design at Google. We’ll be recognizing some of the phenomenal material design work from across the community, so definitely tune in if you’re an Android developer or designer. For more details, check Matias’ post on Google+.
The session will be live streamed so you can follow along in real-time even if you’re not at Moscone. Recordings will also be available shortly after on the I/O website.
Add Design Sessions to your I/O schedule
We’ve dedicated an entire section of Moscone West to design-related programming, including one-on-one and group UX reviews with members of the material design team. Appointments will be on a first-come, first-serve basis, but well also have Google designers on hand for more casual questions.
Add Material Design Reviews to your I/O schedule
Google designers and engineers will host several deep-dive, 20 minute tech talks in a breakout area within the Design Sandbox on Level 2. The space has been designed to facilitate conversation and discussion with small audiences, so come prepared with questions! We’ll be covering a range of topics such as cross-platform and responsive design, designing for platforms like Google Cast and Android Auto, and how to adapt material design to your brand. As an added bonus, most Sandbox Talks will take place twice throughout the conference giving you more flexibility to adjust your schedule.
Add Design Sandbox Talks to your I/O schedule
Explore the full Google I/O schedule here.
Be sure to follow +GoogleDesign and @GoogleDesign, where we’ll be posting design-related announcements throughout the conference. You can also follow and join the general conversation about I/O at #io15. See you tomorrow!

To celebrate the holiday season at Fun Propulsion Labs, were trading our sushi mats and baking pans for candy canes and snowballs. Please join us for a special holiday-themed version of Pie Noon and Zooshi! Zooshi and Pie Noon are open source, cross-platform games built from a suite of libraries that eager C++ developers can use to build their own projects.
You can download and run Zooshis Santa mode on Google Play and find the latest open source release on our GitHub page. The holiday version of Pie Noon is available on Google Play as Snowdown in Santa Tracker and on our GitHub page. Happy Holidays!
* Fun Propulsion Labs is a team within Google thats dedicated to advancing gaming on Android and other platforms.

Now we gonna to add android:stretchColumns="0" to the table layout and see what it’s gonna look like:
Column 0 occupied the largest available space.
TableLayout tl=new TableLayout(this);the setColumnStretchable(ColumnIndex, IsStretchable)method parameters are the column index and a Boolean value to indicate it is going to be stretched.
tl.setColumnStretchable(0, true);
TableLayout tl=new TableLayout(this);The setColumnShrinkable(columnIndex, isShrinkable) method parameters are the column index and a Boolean to indicate it si going to be shrinked.
tl.setColumnShrinkable(0, true);
TableLayout tl=new TableLayout(this);The property setColumnCollapsed(columnIndex, isCollapsed) parameters are the column index and a Boolean to indicate that it’s going to be collapsed
tl.setColumnCollapsed(0, true);
