On the 19th of September, India saw the tech giant go all ‘desi’ at the Google for India event 2019. Initiated in the year 2015 the event has ever since introduced features that cater to the Indian masses. From bringing support for various Indic languages onto a number of platforms such as Search, Lens and Bolo; to announcing a new artificial intelligence (AI) based lab in India. Google for India event 2019, saw the company announcing new products and initiatives that are designed specifically for the Indian users. 

In addition to this, Google also introduced products and initiatives – such as the Digital Payment Abhiyan and the Vodafone-Idea Phone Line. This would eventually connect more people, especially the ones who are not adept at using technology and live in remote areas that lack internet connectivity.

In this blog, let’s have a brush up on all the updates that Google had announced at it’s Google for India event.

7 key takeaways of Google for India event

Google Research India

At the fifth edition of its annual Google for India event, Google announced that it is setting up a research lab focused on artificial intelligence (AI) and its applications in India. Google’s Bengaluru based AI lab, led by Dr Manish Gupta, will focus on two things. Firstly, on the advancement of Computer Science research in India, where it will focus on Machine Learning, Computer Vision, Languages, Speech, Systems, and other related areas. Secondly, it will focus on applying this research to tackle big problems in areas relating to healthcare, agriculture, and education.

Google Pay goes big

Google announced a new Jobs platform that focuses on entry-level jobs that are not easily discoverable online and are often filled via offline channels and backroom hiring centres. It uses Google’s machine learning-based matching algorithm to recommend the best job; scheduling the interview and communicating with their potential employer. As an added bonus, it also has a free CV builder tool.

Google India also launched a special version of Google Pay, Google Pay Business, for merchants. It would enable hassle-free digital payments for small merchants and storefronts. 

Language decoupling & Interpreter mode in Google Assistant

Now Google Assistant supports a total of nine Indian languages. Being available on all Android, Android Go and KaiOs devices, users will now be able to use a local language simply by saying – “Hey Google, talk to me in Hindi”

Google Assistant will now be able to act as a real-time interpreter between two people who don’t speak the same language. To launch the interpreter mode, all users need to say is – “OK Google, help me speak in Hindi“. This feature will be available on Android and Android Go phones in India in the coming months.

Free public Wi-Fi

“With Google’s ongoing commitment to improving access beyond train stations to villages across India, we have partnered with BSNL to bring fast, reliable and secure public WiFi to villages in Gujarat, Bihar and Maharashtra,” Caesar Sen Gupta, Vice-President, Next Billion Users Initiative and Payments said at the Google for India event while making the announcement.

Taking its Google Station program a step further; Google today announced a partnership with BSNL as a part of which it would provide high-speed public WiFi to villages in Gujarat, Bihar and Maharashtra that are yet to get Wi-Fi connectivity.

Vodafone-Idea Phone Line

Google is partnering with Vodafone-Idea to bring Google Assistant to people in areas with poor internet connectivity. Vodafone users who are still using 2G networks can now call a toll-free number – 000-800-9191-000 – to ask their queries to Google; which would then answer them actively.

Discover gets 7 new languages

Google introduced support for seven different Indian languages in the Discover section of its Google app. This includes — Tamil, Telugu, Bengali, Gujarati, Marathi, Kannada, Malayalam. Support for Oriya, Urdu, Punjabi will be made available in the coming months.

Lens gets smarter and better

Users will be able to translate a road sign or a poster or a menu by taking a photo. They can tap on the translate button and select their prefered language. Using Google Lens users can now tap on a word and launch Search directly to look for the details.

8 Best Ways to Reduce Android App Size

5 minutes, 29 seconds read

With the increase in mobile storage spaces that have gone up to 256 GB, app size is also growing. App size is sure to grow as developers are adding new features, trying to meet customer needs, and also trying to support their apps on various screen sizes. Around 74% of the world uses Android, and 70% of users consider app size before installing them. Moreover, as humans are getting accustomed to instant gratification, they ponder on ways to download apps as they take up storage spaces. Despite the cloud support for photos, videos, and files, android users face issues, such as mobile hanging due to app size. As customer expectations are increasing, android app developers are considering other ways to reduce app size while still incorporating significant additional features and keeping in mind the customer experience.

Below are the 8 best ways to reduce android app size:

1. Use Android App Bundle to Reduce App Size

When generating the release version of your app, you can choose between APK and Android App Bundle.  The second option will make Google play to generate the APK with only those features a specific user need. 

Use Android App Bundle

App Bundle Vs APK

Android App Bundle

  • It is a publishing format that includes compiled code and resources of your app, and delays APK generation and signing to Google Play.
  • With Android App Bundles, the compressed download size restriction is 150 MB. The app bundle cannot be used with APK expansion files.
Android App Bundle
Important: In the second half of 2021, new apps will be required to publish with the Android App Bundle on Google Play. New apps larger than 150 MB must use either Play Feature Delivery or Play Asset Delivery.

How to build android app bundles?

To build app bundles, follow these steps:

  1. Download Android Studio 3.2 or higher—it’s the easiest way to add feature modules and build app bundles.
  2. Add support for Play Feature Delivery by including a base module, organizing code and resources for configuration APKs, and, optionally, adding feature modules.
  3. Build an Android App Bundle using Android Studio. You can also deploy your app to a connected device from an app bundle by modifying your run/debug configuration and selecting the option to deploy APK from app bundle. Keep in mind, using this option results in longer build times when compared to building and deploying only an APK.
  4. If you’re not using the IDE, you can instead build an app bundle from the command line.
  5. Test your Android App Bundle by using it to generate APKs that you deploy to a device.
  6. Enroll into app Play App Signing. Otherwise, you can’t upload your app bundle to the Play Console.
  7. Publish your app bundle to Google Play.

Please note: Android Package Kit – As per developer console, by the mid of 2021, developers won’t be able to upload apk on play store)

  • Android operating system uses APK which is the package file format for distribution and installation of mobile apps, games and middleware. APK is similar to other software packages such as APPX in Microsoft Windows or a Debian package in Debian -based operating systems.
  • Google Play requires that the compressed APK downloaded by the users should not exceed 100 MB.
  • The expansion files for your app are hosted by Google Play which serves them to the device at no cost to you. The expansion files are saved to the device’s shared storage location (the SD card or USB-mountable partition).

2. Use Proguard

Proguard is probably one of the most useful tools to reduce your APK size. It reduces the source code files to a minimum and can reduce the APK file size upto 90%.

  • Use it in all variants whenever using “Proguard”
  • Helps to avoid conflict at the of generate apk or bundle if will use in all the variants.
  • We cannot let ProGuard rename or remove any fields on these data classes, as they have to match the serialized format. It’s a safe bet to add a @Keep annotation on the whole class or a wildcard rule on all your models.

3. Use Android Size Analyzer Plugin

This Android Studio plugin will provide you recommendations to reduce the size of your application.

With the APK Analyzer, you can accomplish the following:

  • View the absolute and relative size of files in the APK, such as the DEX and Android resource files.
  • Understand the composition of DEX files.
  • Quickly view the final versions of files in the APK, such as the AndroidManifest.xml file.
  • Perform a side-by-side comparison of two APKs.

There are three ways to access the APK Analyzer when a project is open:

  • Drag an APK into the Editor window of Android Studio.
  • Switch to the Project perspective in the Project window and then double-click the APK in the default build/output/apks/ directory.
  • Select Build > Analyze APK in the menu bar and then select your APK.

4. Optimize Your App’s Resources

Whether used or not, every resource takes up memory. It is therefore necessary to have only those resources that you need, and to use those in a memory efficient way. In other words, you should consider the resolution of the image before finalizing on it.

5. Optimize Libraries

As large libraries consume huge amounts of space, it is advisable to remove parts of it in case you do not need them and if it is permitted by the license of the library. Proguard can aid you in this process but it is not always able to remove large internal dependencies.

6. Use Vector Graphics Wherever Possible

They are sharp and do not consume much space as they rely on mathematical calculations and not on pixels that need to be saved. However, they cannot be used for photography.

7. Compress Your Images

By using tools such as pngcrush, you can reduce the file size of PNG images. It is advisable to do this images as they still look the same. 

8. Only Support Specific Densities

If only a small portion of users use a specific density, it might be better to let Android scale your other densities for them as it would reduce your APK size.


As mobile storage space is growing, people are installing a large number of apps to meet a wide range of needs. But as app size is increasing, people are continuing to struggle with storage issues. With provisions such as Proguard, one can compress the APK file size and optimize libraries easily. Compressing images and using vector graphs are also useful in reducing app size.
