in Android Studio, Best Practices

The Ultimate Checklist For Developers on the Android Studio IDE

The moments just before the app launch are magical. You are thrilled at the possibilities and mortified by the future at the same time. “What will I do if there are a million downloads within the first hour?!”, “What if nobody wants my app ever?” – questions like these keep swimming and turning in your mind, keeping you restless. If you’re in 30the pre-launch fever right now, hold your horses! 

Now is a good time to review the important steps that you need to consider before you launch your app. Here’s a small but useful checklist on the Android Studio IDE that we can recommend.

The Ultimate Checklist For Developers on the Android Studio IDE


#1 Version compatibility check

Run your app through different emulator versions one last time. It’s possible that while you tested everything a few days ago, some recent changes are completely breaking the app on a new device. While the approach of firing up emulators one by one and testing things manually is fine, to begin with, consider using something like Genymotion if you can invest some money.

#2 Code security

Make one last check through your static analyzer to see that the code is all fine and no gaping security holes exist. You can use something like for this.

#3 Optimize your layouts

As an app grows more complex, so does the UI. You’d be surprised to know how much badly structured UIs and nested components can slow down your app. Make sure you run it by a layout optimization tool to ensure the UI is lean and efficient. It’s quite easy to do so in the Android Studio IDE.

#4 Optimize network use

Does your app need to be using the Internet all the time? Most likely not. As such, now is a good time to check how often your app uses the Internet and drains the user’s battery. If you find your app acting greedily, figure out a quick lazy-use plan and change it.


#5 Windowing changes

One small aspect of Android security best practices is not to show the title of the app. You can set this using the –

this.requestWindowFeature(Window.FEATURE_NO_TITLE) function.

Also, it’s better to let the app run in full-screen mode always; this can be achieved by using the –

this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN) property.

#6 Reduce app size

As you keep adding functionality to your app, library dependencies increase and before you know it, several JAR files you don’t need become part of your app. Automated dependency management is great, but does bloat the app quite a bit. If possible, at this step you should get off Gradle and pick only the JARs that you need.

#7 Optimize images

If your app is image-heavy (and even if it’s not) you should consider optimizing the images before you launch. There are several tools like PNGCrush, OptiPNG, etc., that can scale down the images.

If the pre-launch process were to be summed up in one word, we’d say “optimize”. Optimize for everything: speed, memory, UI, UX, marketing, rating, ads, everything. Have a successful launch!
