Google Developer Group Philippines

Today is the tenth anniversary of GDG Philippines. Google Developer Group (GDG) Philippines is a group of enthusiastic Filipino developers interested to collaborate and learn more about new technologies. It is the second oldest GDG in the world. Happy 10th year GDGPH!

I was one of the community managers of GDG Philippines. It started as me being a regular attendee during the early days of GDG. Around 2009, I became one of its managers. We plan and organize events for students and developers in Metro Manila and nearby cities. To make these happen, we coordinate with sponsors, speakers, and suppliers for our community events. We also conduct talks and workshops about Google developer technologies on conferences and schools whose students invite us. I usually do talks and workshops about Android development. I have also facilitated Android Fundamentals and Android Basics Study Jams. I was also one of those who handled the blog and social media accounts of the group.

Some of my contributions to GDG Philippines include developing apps which I did while learning about Google developer technologies. The GDG Philippines Android App, which was one of the first GDG Android apps published on Google Play, was one of my first Android apps I have made. My first Google Chrome Extension, the GDG Philippines Chrome Extension, was the first GDG Chrome Extension IIRC. While learning about developing apps for Google Assistant, I have developed a Google Assistant App for GDGPH too. I also created applications for event registrations and check-in, as well as a raffle app based on the list of attendees.

I've been in GDG Philippines for quite a long time that it has been my second family. Our goal is to help developers become better developers. It have made me a better developer and a better person. There's also a sense of accomplishment when you were able to share your knowledge to the attendees and inspired them to learn more and use it to develop their own apps. In most schools that we've been too, Android is not yet a part of the curriculum so it's great we were able to let them know the what, why, how, and more. I also get to learn some more while teaching others.

Through GDG, I have been able to expand my network and meet other managers from tech groups in the Philippines and fellow GDG community managers from Southeast Asia and other regions. I also had the opportunity to meet and learn from Googlers and experts. We were able to travel to different cities in the Philippines (especially the ones where there aren't much tech events) to share about Google developer technologies through talks and workshops. I have been able to attend Google I/O where I learned a lot which we shared back to the community through the I/O Extended Roadshow.

It is truly a great experience to be a part of GDG Philippines. If you still haven't joined a GDG Philippines event, join us now! Learn more about the group and our events at and follow our social media accounts.

You and Me

Last year, I started working on an Android App for Celine. I was only able to finish it this year though. The app is named You and Me and it is the app for you and your special someone. You can use the app to check your photos (and soon more!) with your significant other.

I published it under Closed Alpha Testing on Google Play Store because there's still more to be done for it to be useful to other couples. I'll continue working on it and release it soon.

Tigcal Utilities

Earlier this year, my mother switched to a smartphone. The transition to getting used to a smartphone took a while. She was having issues opening the Quick Settings to access the Flashlight and checking Battery status. As an Android developer, I decided to create simple apps to solve these problems. I have also planned to develop an app for the electric bill-splitting which they normally do manually.

The result of this initiative is what I call Tigcal Utilities. Instead of making three apps, I made an app that has three functions. This includes the following utility apps: Battery, Bill Calculator, and Flashlight.

The Battery app opens the Battery Usage Settings while Flashlight app allows the user to turn on and off the flashlight. Flashlight uses Camera2.

Bill Calculator is an app that allows users to split the electric bill based on total kWH used.

I decided to publish it on Google Play Store so any future update will automatically be downloaded to the phone (if it has internet connection). As it is a special app, I published it on closed Alpha Testing. If you want to try Tigcal Utilities (and provide feedback), let me know so I can add you as a tester.

Developing Apps for Google Assistant

Google Assistant is your own personal Google. It's one Assistant that's ready to help you get things done, no matter where you are or what device you're using. With it, you can have a natural conversation and ask questions, take actions and do more.

Developers can create applications for Google Assistant by creating Actions on Google. Actions on Google is the platform that allows developers to build for the Google Assistant on Google Home, Android phones, iPhones, and wherever the Assistant will be available. Developing apps for the Assistant is free (no need to register for a developer account) and easy. The apps you will built will be available to every devices where there is Google Assistant. Users don't need to download anything to try your apps.

To develop for Actions on Google, you would need to create a project in the Actions on Google Developer Console. You can use Actions SDK or conversational platforms like, which wraps the Actions SDK into an easy-to-use user interface. Using is free; it also allows you to develop apps not just for Actions on Google. You can create apps without coding but you can also use webhooks to add more functionality.

I have started developing apps for Google Assistant: Budget Penny and GDG Philippines. Budget Penny is your budget assistant that's ready to help in managing your finances. Simply tell her your monthly budget and update her of your expenses as often as you like. Moreover, you can ask her how much is your remaining balance or whether you still have budget. Learn more about Budget Penny here.

I have also made a Google Assistant app for the Google Developer Group (GDG) Philippines community. You can ask it about the upcoming events and more information about GDG Philippines. I have used and webhooks using Firebase, Cloud Functions, and NodeJS for these apps. I'll continue working on these apps and build new ones soon.

If you want to create your own Google Assistant Apps and learn more about Actions on Google, you can check out the documentation at and join the Actions on Google Developers Community at

Budget Pinoy

Sweldong Pinoy is now five! We have been developing a new app called Budget Pinoy. I'm reposting below the announcement blog post which was originally published in the Sweldong Pinoy Blog.

Need help in budgetting your salary? Want to find out what your asking rate is depending on your projected expenses and budget? We have developed an app that can help you!

Budget Pinoy is a tool for Filipinos in computing gross and net pay based on user's budget.

Users can input their target savings and projected expenses in the Budget Tab. They can also use the expenses tab to check expenses.

The recommendation tab will show the asking rate that the user needs to be able to earn enough for the target budget. It will also show the net pay and deductions, computed using Sweldong Pinoy, based on the asking rate.

We're also working with different financial institutions to give you relevant tips to help you in your finances, based on your budget. This will be coming soon in a future update.

Try Budget Pinoy at and let us know how we can improve the app to help you more in your budgetting needs.

7-Eleven Run 2017

For the third straight year, I joined 7-Eleven's run for the year, the 7-Eleven Run 2017.

Photo from

I ran again in the 16k category. Runtastic says I ran 16.04 km in 2:14:44. The official results are 02:15:29 (Gun Time) and 02:14:09 (Chip Time).

While this year's run was better than last year, my comments from 2016 are still the same comments I have for this run.

2016 in Numbers

At the end of each year or at the start of the new year, I have traditionally published year-ender blog posts to look back on the past twelve months of my life. As I reflect on how 2016 has been for me, I was reminded that not much happened this year. There were some gains but there were more losses. It would be hard for me to enumerate the top things that happened or to summarize the highlights for the year so I would just list down some of the relevant numbers.

3 runs (two 16k runs and a 10k run)
1 Chrome Extension (Android Gradle Extension)

0 new Android Apps published (though I'm stil working on at least two apps)
2 Android Study Jams facilitated in 2 Schools
1 Android App Development Competition Judged (STI App and Running 2016)
8 Android Workshops
9 Android Talks

1 local event attended (PWA Roadshow Manila)
1 international event attended (Google I/O 2016)
4 new local places (Palawan, Bohol, Dipolog, Dapitan) visited for the first time
5: Fifth US State (Washington) when we visited Seattle

I am praying 2017 will be a lot better than 2016. I'll do my best to do more stuff and accomplish more.
