50% of Indian and Indonesia Android smartphone users do not have any access to wifi... ⭐️ For every 6 MB increase to an APK’s size, we see a decrease in the install conversion rate of 1%. Now imagine if you user base is in millions, what would actually happen if your loss is just 1% Reducing APK size on Android is crucial for improving app performance and user experience. Here are some key strategies to achieve this 🎁 𝐔𝐩𝐥𝐨𝐚𝐝 𝐲𝐨𝐮𝐫 𝐚𝐩𝐩 𝐰𝐢𝐭𝐡 𝐀𝐧𝐝𝐫𝐨𝐢𝐝 𝐀𝐩𝐩 𝐁𝐮𝐧𝐝𝐥𝐞𝐬 Generate a bundle, using Android Studio, and upload it to the Play Store, and the rest will be taken care of. Play Store, will only pick the app from the bundle, which is compatible with the phone architecture, and allow the user to download only that much size 🥶 𝐑𝐞𝐬𝐨𝐮𝐫𝐜𝐞 𝐒𝐡𝐫𝐢𝐧𝐤𝐢𝐧𝐠 Libraries that you add to your code might include unused resources. Gradle can automatically remove resources on your behalf if you enable shrinkResources in your app's build.gradle.kts file 📁 𝐔𝐬𝐞 𝐚 𝐥𝐨𝐬𝐬𝐥𝐞𝐬𝐬 𝐜𝐨𝐦𝐩𝐫𝐞𝐬𝐬𝐢𝐨𝐧 𝐟𝐨𝐫𝐦𝐚𝐭 𝐥𝐢𝐤𝐞 𝐖𝐞𝐛𝐏 Instead of using PNG or JPEG files, you can also use the WebP file format for your images. The WebP format provides lossy compression and transparency, like JPG and PNG, and it can provide better compression than either JPEG or PNG. 🛵 𝐔𝐬𝐞 𝐃𝐲𝐧𝐚𝐦𝐢𝐜 𝐅𝐞𝐚𝐭𝐮𝐫𝐞 𝐌𝐨𝐝𝐮𝐥𝐞𝐬 Dynamic feature modules allow you to separate certain features and resources from the base module of your app and include them in your app bundle. Users can download and install these modules later on demand after they’ve already installed the base APK of the app using Dynamic Delivery. For example, if your app has a custom camera feature you can make it a dynamic module and users can download and install the custom camera on demand. Apps like Instagram and Paytm do this for a lot of features 👨🏻🦯➡️ 𝐌𝐢𝐧𝐢𝐦𝐢𝐳𝐞 𝐃𝐞𝐩𝐞𝐧𝐝𝐞𝐧𝐜𝐢𝐞𝐬 Regularly review your app, and check, if the libraries you've declared are actually required or not. If they're not required, remove them, or if there is an update available, keep updating them so that you have the latest and greatest size optimisations available Some interesting articles are included in the comments..

Gemini is now being Integrated on the Developer Docs pages as well 🤖😍 It adds a small shortcut, that can explain a particular code using Gemini, and has a small magic ✨ button ⭐️ It is very similar to a ChatGPT or AI tool integrated in your browser kind of experience Take a look at the image to know more This is taken from : https://lnkd.in/dHUrt6UJ #ai #gemini #google #android #androiddev #ios #swift #java #kotlin #gpay #payments #androidstudio #developer #softwareengineering #softwareengineer #programmer #productivity #flutter #kotlinandroid #javaandroid

WWDC 2024 is here! WWDC: We Wait, for (already) Done Changes (on Android) While there's so much buzz around what's new to Apple platforms.. Do we have any easy way to get through the App Store reviews? 🤣 #wwdc #wwdc2024 #linkedin #apple #googleio #cupertino #ios #ios18 #siri #gemini #ai #socialmedia #instagram #facebook #google #marketing #india #android #androiddev #flutter #swift #objectivec #objc #spm #xcode

Gradle's Configuration 🛠️ Cache 📕, and why you should know about it... What is it? 🤔 The configuration cache is a feature that significantly improves build performance by caching the result of the configuration phase and reusing this for subsequent builds. Using the configuration cache, Gradle can skip the configuration phase entirely when nothing that affects the build configuration, such as build scripts, has changed. Gradle also applies performance improvements to task execution as well. In layman terms, if you run a command, gradle saves a lot of things required for that command, and will reuse them, if the same command is run again How do you use it? 𖧝 You can enable the flags selectively for a command using "--configuration-cache" , or enable it for your project by setting the flag "org.gradle.configuration-cache=true" in the "gradle.properties" file You can also enable the feature preview "Stable Configuration Cache", by using the flag "STABLE_CONFIGURATION_CACHE" which can output meaningful errors Bonus: I tried executing two of the most commonly used tasks in my organisation, and the build times were 2X FASTER 🤯.

Know your Libraries 🤔: Dagger 🗡️ "Just get me the object, man" ⭐️ Dagger is a Library very widely used in Android projects, for facilitating dependency injection, or in layman terms, "Just get me the friggin object, mate?" ⭐️ Dagger comes from DAG ( Direct Acyclic Graph ), commonly used data structure for dealing with dependencies, and used in many Operating Systems as well ⭐️ Dagger 1.X was first developed by Square, who's also the development team behind widely used libraries by Retrofit. Dagger 2 has considerable improvements in performance as it doesn't use Reflection anymore. Detailed comparision can be found here https://lnkd.in/gSqUhrtT ⭐️ Dagger 2 also features Compile Team validation, unlike competitors like Koin. Using Compile Time Validation, you already know the missing dependencies, at compile time, and the price to pay is the build time. Koin has a relatively faster build time, but on compile time validation. So you choose your poison ☠️ Bonus 😍 Getting started with a big complicated project involving dagger? You can actually visualise the DAG ( Direct Acyclic Graph ) generated by Dagger, using Scabbard (https://lnkd.in/gTFx3sXd).

Trying to get a meaningful log out of an error in your Android app? 🤔 Read on... 👨🏼💻 Use a stacktrace 🧶 What is a stacktrace? ℹ️ It is a stack of all methods that were called, before the error happened in your app, and IDEs like Android Studio, can deep link to the actual method sometimes, making it very convenient to know where things went wrong But... Often, people use the "ex.printStackTrace()" function call, to print what went wrong. However, this is an elementary mistake, since this stack trace might be printed in a release app as well, and some evil actors might get a good idea about your app internals ❌ Kotlin provides a better extension function "stackTraceToString()". This is an extension function on the "Throwable" interface. You can easily use it using the good old "Log" class in Android. ✅ Bonus: 🤑 You can strip off unnecessary "Log" calls, using proguard. The rules can be found in this post in the comments!

What's so cool in Kotlin 2.0? 🤯ℹ️ Kotlin 2.0 introduces "Explicit Backing Fields" which can streamline property definition for you. I'm sure you would have seen a private and a public property being defined for a state in a class, just so that it can be easily modified in side the class and not editable outside the class, it's going to super simplified now Haven't updated to Kotlin 2.0 yet? You can use this feature in Kotlin 1.7+ by enabling the experimental K2 compiler using "-Xuse-k2" and "XXLanguage:+ExplicitBackingFields" as the language feature flag. Not recommended though. No IDE support for this version Take a look at the animation to know more.... Follow Gaurav Thakkar for more such interesting insights!

The AutoCloseable interface is now stable in Kotlin 2.0 The below shows how you can create a custom class "XMLWriter" with a function flushAndClose to release all the resources After that, you can create an implementation of the "AutoCloseable" interface and call the "use" function to make sure it releases resource after the last line of code in that block is executed. No more messy close/ release resources call Isn't it interesting? #kotlin #java #android #androidstudio #mobileapps #programming #linkedin #networking #software #softwareengineering #softwareengineer #programmer #kotlinandroid #kotlinmultiplatform #kotlin2
