Tips for Android beginners

A while ago someone asked on Quora how to learn Android development. The person had knowledge of Java, but none of XML. I suppose the fear of XML came from the fact that is well known that Android uses a lot of XML. I started with a quick clarification on XML syntax and that’s the only required knowledge of XML. The parsing is done automatically by the Android system or the build tools.

GDG Talks #1

Usually every month we have an informal meeting at GDG Campinas, where we gather and discuss whatever comes to mind (most of the time it’s Android, the preferred topic for most of the attendees), but this month we decided to do something different. Organized by Karuan Bertoluci, this month meeting was a series of three talks hosted at Ci&T, which provided the venue and some beverage and food. After Karuan opened the event, I gave the first talk on Android Wear.

Messing MacVim

I published a new version of MacVim on last week Monday and was quite happy with it. It was early morning, I published it at 7:30 AM (UTC-3) and went to work. Of course, being an avid user of Vim, the first thing I did at work was updating my copy of MacVim. Then things went awry. MacVim crashed at launch (of course, it didn’t occur at home). E-mails started popping on my inbox.

MacVim is back on track

It’s no secret I’m a big fan of Vim. Although I can use it in the terminal, I like to have a nice UI to look at and when I’m on a Mac (e.g., at work), I use MacVim. I have no words to thank the amazing job behind both Vim and MacVim and I always wanted to contribute back. I’ve been building MacVim for older versions of Mac since 2012 and since Björn has been busy, I’m maintaining it now.

3.11

Three years ago, on March 11th, a tsunami hit the east coast of Japan killing 19000 people and leaving many others homeless. Still today many of them can’t return to their home due to radiation near Fukushima disaster. Yahoo!Japan had a great initiative, donating 10 yen for each search for “3.11” See the announcement: http://promo.search.yahoo.co.jp/searchfor311/ and the video below:

Happy Birthday, WWW

25 years ago, Sir Tim Berners-Lee created the World Wide Web, read about it on Computer History Museum. Seeing the pictures makes me nostalgic. I used WindowMaker when I started using Linux in 1999 and it’s inspired by NeXTSTEP. Update: Another legendary Tim made a nice post: https://www.tbray.org/ongoing/When/201x/2014/03/11/The-Web-is-25 (that’s Tim Bray, co-creator of XML). Also, celebrate at http://www.webat25.org/

Understanding Android Open Source Project

A while ago someone asked on Quora about some good ways to understand the AOSP. Although I don’t work with Android internals anymore, it was fun looking back into AOSP and finding some sources (no pun intended). Here’s my answer (edited for this blog): Obviously, first go to AOSP site and follow the instructions to download the source. Although outdated, take a look at Android Platform Developer’s Guide (it’s a copy of the old PDK, removed from Android site now).

The Setup

There are a lot of posts about how someone uses their computer to get the job done. One of my favorite sites that compiles a list of posts like that is The Setup. As I like to keep track of what I use, I’m doing my own The Setup-like post to open this blog. Who are you, and what do you do? I’m Douglas Drumond, Android developer at Movile and organizer of GDG Campinas.

My Git Workflow

Proceeding with my sequence of posts about version control systems, I’ll explain my Git workflow. It’s quite simple, after set up, the day to day workflow is as follows: get the latest information from remote server: git pull --ff-only create a new branch and switch to it: git checkout -b branch_name work, work, work, then commit: git commit go back to master: git checkout master check if there’s something new: git pull --ff-only merge my work back into master: git rebase branch_name upload the modifications to server: git push And since I reached the magic number seven, those are the seven steps.
