Improve and measure the speed of your Android App Startup times

The app’s speedy startup time is essential to provide users an enjoyable experience. According to studies, 20% of users are likely to leave an android app when it takes longer than five minutes to load. As an app creator, you should constantly evaluate and improve your app’s initial performance. Here are some ideas on how you can do this.

The time it takes to start your app.

It is the first thing to determine the speed at which your app is running. There are many instruments you can utilize:

Android Studio Profiler

The Android Studio Profiler allows you to determine when to start your application. How to utilize it:

  1. Start your project within Android Studio.
  2. Go to”Profile” and then click the “Profile” tab.
  3. Choose”Methodtracing” as the “Method tracing” profiling mode.
  4. Run your app.
  5. Stop profiling your app when it is fully loaded.
  6. Review the trace. This will reveal the time for each step of the process to start.

The profiler lets you see which techniques consume the most time to start. This allows you to pinpoint areas for optimization.

Third-party tools

There are several third-party tools that you can make use of, like Trepn Profiler AppsFlyer in addition to Appsee. They provide additional metrics beyond the essential startup time, such as CPU utilization and network requests. You can also compare startup times across various devices.


Additionally, you can manually add Log statements during the app’s startup to determine time deltas. Examples:

Copy code

Log.d(“StartupTime,” “App init began”);

//… perform app init

Log.d(“StartupTime”, “App init took ” + (System.currentTimeMillis() – startTime) + “ms”);

Check the Logcat output to determine the time stamps. The drawback is that it manually adds Log calls to every point of significance.

Track user metrics

An alternative is to observe users’ actions during startup, such as “first tap” or “first product view.” By relating this data to the startup duration, it is possible to build models to predict typical times for startups on the ground. Monitoring user metrics can help determine the startup speed under real-world situations.

The ability to reduce the startup time of your application

Once you’ve got a clear picture of the performance of your app’s startup, Here are some suggestions to cut down on the time it takes to start:

Make sure you have a well-designed manifesto.

  • Only declare necessary elements such as Services, Activities, etc. Make sure you remove any unnecessary declarations.
  • Specify the Android:directBootAware attribute to defer the loading of components until needed.
  • Add android:extractNativeLibs=”false” to prevent extracting native libraries if not needed.
  • Use Android: hardware-accelerated to enable hardware acceleration for Activities that need it.

Initialize components lazily

Don’t initialize everything at the time of startup. Only load components when they’re required. Examples:

  • Insist on a lazy initialization of libraries and SDKs in the specific Activity/Fragments that utilize them, rather than starting them at the beginning of each day.
  • Download significant UI elements, such as large videos or images, unconsciously.

Reducing the main thread work

As little as you can in the primary thread during initialization. Start information in lines running behind to prevent obstruction to the UI. Common examples:

  • Database queries and I/O to files
  • Initializing SDKs
  • Inflating layouts

Use AsyncTask, IntentService, Loaders, or RxJava Observables to perform background tasks.

Improve the layout to increase and reduce inflation.

Layout inflation can consume an essential portion of the time to start. Making it easier to manage this can yield enormous benefits.

  • Use ViewStub, the ViewStub class, to fill heavyweight layouts slackly.
  • Create larger layouts and only show them at times when required.
  • Utilize ConstraintLayout for structures that are nested whenever it is
  • You can flatten layouts nested in the arrangements if you are able.
  • Do not design structures that have too many perspectives.

Minimize initialization of apps and activities.

Make sure that your Activity and Application are kept to a minimum. Initial logic to a minimum.

  • Applications created using onCreate() should be used only to create application-wide singletons. Perform other tasks when needed.
  • Transfer Activity Initialization Code away from onCreate() onto the onStart().

Utilize resources efficiently

Video and image resources could make your app bloated. Be sure to load them with care:

  • Convert image resources using tools such as TinyPNG.
  • Reduce large images to smaller sizes as needed.
  • Common image resources are reused across layouts.
  • Use WebP format for smaller images.
  • Video content streaming instead of bundling it as a file.

Additionally, you should move any resources not required during app startup from the main app to the expansion file.

Requests for Profile Network

Unoptimized network requests during startup create loading delays.

  • Install network libraries such as Retrofit/Volley in a lazy fashion to minimize the impact of a startup.
  • Utilize profilers like OkHttp and OkHttp to examine the network calls.
  • Concatenation, caching, and compression of requests to the network.
  • Only download the required data at the initial startup. Do not delay requests that are not critical.

Modify your code

Split your app into logical parts and make sure that they are initialized independently

  • Separate the core functionality from the additional features
  • Separate library and app modules into different Gradle projects
  • Only start the runtime libraries if needed

Test on real devices

Always test the performance of your application on actual devices, particularly those with low or mid-range specs. Many issues, such as performance bottlenecks, aren’t apparent when using emulators. Check both release and debug builds.

Enable Android App Bundles

Utilize Android App Bundles to reduce the size of your app. In addition, the Play Store will download optimized APKs for every device configuration, meaning fewer downloads and installations.

Continuously improve startup speed.

Optimizing startup times for apps isn’t a one-time event. As your app grows, keep:

  • Monitor startup times and monitor the time of startup using profiling tools
  • Set budgets for the performance of the app initialization
  • Include the time of startup within your Continuous Integration benchmarks
  • Include startup optimizations in your release requirements
  • Monitor the startup performance of the user’s devices
  • Keep abreast of the latest software, devices, and compiler enhancements

Optimizing is an essential aspect of the development process, and throughout the release cycle, it is possible to provide a lightning-fast Android app experience.
