I started working full-time as a Java developer after graduating in 2009. It was around that time that I got to learn about Google developer technologies, especially Android. There weren’t much Android phones yet but I had believed Android will be the future. A few months later (already 2010), I started loooking into the developer documentation and studying about developing Android apps.

In 2011, I bought my first Android phone: a Nexus S and subscribed to a Globe postpaid plan. Nexus devices then do not have a SIM tookit and Globe does not have an app for it. I decided…

App Signing by Google Play has been around since 2017. With App Signing, Google manages your app signing keys and uses it to sign your APKs for distribution. Enrolling your app in App Signing is optional. You might have decided to handle the signing and storage of your keys instead of uploading them to Google Play.

Now, you have changed your mind and want Google to manage your signing keys instead of doing it personally. Or you want to try to reduce your app’s size and simplify the release process with Android App Bundle but you are required to use…

Google launched the Android 11 Beta with pages, videos, and other resources on June 10. They also announced the 11 Weeks of Android. Each week focuses on a specific topic and they will release more content relevant to it. Global developer communities will also host Android 11 Meetups to help developers learn and prepare for the new Android version.

GDG Philippines has invited me to be their speaker for their Android 11 meetup. I’ve done Android talks and workshops with them before. However, this time it is going be online, which will be the first time for me. …

As an Android developer, you’re most likely using Android Studio for development. Installing, updating, and uninstalling, especially you have several variants, is sometimes time consuming and can distract us from coding. I recently learned something which can help make this easier for developers, the Toolbox App.

Toolbox App is a free application from JetBrains that allows you to manage your development tools. It’s like a control panel for IntelliJ and their other IDEs but it can be used too for Android Studio.

Toolbox App with Android Studio

With Toolbox, you can download Android Studio and install side by side stable, beta, and canary versions. …

Today (November 19) 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…

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)…
