Introduction

In today’s digital world, mobile appliсations have beсome an indispensable part of our everyday lives. However, with growing user expeсtations around app performanсe and stability, monitoring and improving mobile app performanсe has beсome сruсial for developers. This is espeсially important for Android apps сonsidering the fragmentation of Android deviсes, Android Automation, and operating system versions.

Automated testing tools can help Android developers tackle these fragmentation issues and monitor app performance through its Android emulator cloud.

Importance of Monitoring Mobile App Performance

Considering user expectations, monitoring app performance has become essential for developers. It helps them identify issues that impact stability and speed to enhance overall user experience.

The key aspects that need monitoring include:

• Load Time: Monitor app launch time and page load times to catch performance bottlenecks. Identify specific user actions that may trigger delays.
• Crash Rate: Track app crash percentages across builds/versions to fix stability issues. Monitor ANR rates as well.
• Network Traffic: Keep tab of network calls made by the app to optimize data/traffic usage and signaling load.
• User Behavior: Track user actions, taps, swipes, rage clicks etc. to fix navigation/UX issues that impact experience.
• Adoption/Retention: Gauge daily/monthly active users, session length, churn rate etc. to identify engagement bottlenecks.

Now, let’s dive into how to monitor and improve performance step-by-step.

Step 1: Monitoring App Performance

You can’t fix what you don’t know is broken. Monitoring means collecting data about your app while it runs on real users’ devices. Here’s what to track and how to do it.

Key Metrics to Monitor

1. App Load Time:
   • How long it takes for the app to start or а screen to appear.
   • Goal: Under 2-3 seconds (users get impatient otherwise).
2. Response Time:
   • How fast the app reacts to taps, swipes, or button clicks.
   • Goal: Less than 1 second for simple actions.
3. Crash Rate:
   • How often the app stops working and closes unexpectedly.
   • Goal: Keep it below 1-2% of sessions.
4. Battery Usage:
   • How much power the app consumes.
   • Goal: Avoid draining the battery too quickly.
5. Network Performance:
   • How fast data loads (e.g., images, videos) over Wi-Fi or mobile data.
   • Goal: Quick downloads, even on slow networks.
6. Memory Usage:
   • How much device memory (RAM) the app uses.
   • Goal: Stay low to avoid slowing the phone.
7. User Retention:
   • How many users keep using the app over time.
   • Goal: High retention means good performance and experience.

Step 2: Understanding the Data

Once you’re collecting data, you need to make sense of it. Here’s what to look for:

Crash Reports

• Example: “App crashes on iPhone 13 when tapping ‘Save’ button.”
• Dig Deeper: Check the error message (e.g., “Null Pointer Exception”) and the device type.

Slow Screens

• Example: “Profile page takes 6 seconds to load.”
• Dig Deeper: Is it the network? Too many images? Bad code?

Battery Drain

• Example: “App uses 20% battery in 30 minutes.”
• Dig Deeper: Is it а background task or heavy graphics?

User Drop-Off

• Example: “50% of users leave after the loading screen.”
• Dig Deeper: Is it too slow or crashing?

Tools like Firebase or Sentry give you dashboards with graphs and details. Spend time here—it’s your roadmap to improvement.

Step 3: Improving Mobile Performance

Now that you know what’s wrong, let’s fix it. Here are practical ways to boost your app’s performance, broken into key areas.

1. Speed Up Load Times

Slow apps lose users. Here’s how to make them faster:

Optimize Images

• Problem: Big images (e.g., 5MB PNGs) slow down loading.
• Fix: Compress them with tools like TinyPNG or use formats like WebP.
• Example: A 5MB image becomes 500KB—10x faster to load.

Lazy Loading

• Problem: Loading everything at once slows the app.
• Fix: Load only what’s on screen (e.g., images below the fold load later).
• Code Example (Android):

imageView.setImageResource(R.drawable.placeholder);

new Thread(() -> loadImageFromNetwork(imageView)).start();

Cache Data

• Problem: Fetching data from the internet every time is slow.
• Fix: Save data locally (e.g., user profile) and refresh only when needed.
• Tool: Use Room (Android) or Core Data (iOS).

Challenges in Android App Performance Monitoring

While performance monitoring is indispensable, Android app testing brings its unique set of challenges that make the task harder for testers:

• Device Fragmentation: With over 24000 unique Android device configurations across various OEMs, OS versions, screen sizes etc., testing on all possible combinations is complex.
• Emulator Limitations: Native emulators lack scale and speed in mimicking real devices. Maintaining multiple emulators is also time-consuming.
• Lab Infrastructure Overheads: Setting up real device labs is expensive, with significant overheads around device procurement/maintenance.
• Outer Loop Feedback: Collecting performance metrics post app release offers delayed feedback. Developers need inner loop feedback to catch issues much earlier.
• Manual Testing Efforts: Validating app performance via manual testing can be slow, repetitive and error-prone.

Thankfully, the LambdaTest Android cloud helps developers overcome these challenges with test automation.
