Get Started with Python

If you’re a programmer, surely you’ve heard about Python. A general-purpose programming language, Python can be used for just about anything, from web development to artificial intelligence and many others. It is also an interpreted, dynamic and high level language that is designed to read like the English language, allowing you to integrate systems more effectively and deliver code faster compared with other coding languages. On the other hand, if you’re completely new to the world of programming, Python is created in a way that beginners could easily understand and lets newbies learn how to code without having to worry much about the confusing and tedious details.

Tips to Improve Android App Performance for Developers

Nobody wants to use a slow-running app.

Nowadays, great performance and responsiveness are crucial to the success of mobile apps. You may have created an app that is novel and could be a solution to a certain problem, but if it lags or uses a lot of the device’s memory, your app will most probably be uninstalled.

To avoid that, here are some tips to improve the performance of your app and give your users a smooth and awesome experience:

Tip 1. Avoid Application Not Responding (ANR)

ANR is one of the most dreaded bugs an Android app can have. It makes the app slow, sluggish, and frozen. It impacts UX and your app usability. To lessen ANRs in your apps, make sure long running tasks are not contained in the UI thread. Tasks like downloading and API calls should be implemented inside AsyncTask, IntentService, or Threads. Furthermore, progress dialogs can also be displayed to enhance UX.

Tip 2. Hardware/software Fragmentation

Hardware/software fragmentation is the discrepancy between different android OSes and devices which are currently in the market. This makes it hard to write a code that can encompass several criteria. A workaround for this problem is checking the lowest and most used Android OS and make sure your code works on it. You can also use Android Support Library to implement newer features on older OS. Google has also been known to address this problem using their next release, the Android N.

Tip 3. Consider running the Android Lint tool on your project

The Android Lint Tool offers insights on optimization improvements and could help you find anything in your code that could possibly be a bug.

To run the lint tool, open your project and simply select Analyze > Inspect Code.

Tip 4. Optimize App Speed

Avoid the creation of unnecessary objects in your code to reduce the work of the garbage collector. Frequent garbage collection will affect the device’s memory thus, making the app slower. When using lists, which are staple on many Android apps, use View Holder Pattern or Recycler View. These optimize the list view by reusing list item views, making the list scrolling buttery smooth.

Tip 5. Track down Memory Issues

Use MAT(Memory Analyzer Tool) to track memory usage and reduce leaks which cause the app to crash.
