There is one thing where developers have to face challenges and that is screen size. As we know android devices have multiple screen sizes and shapes. So, they have to take care of rigid dimensions in your layout for a particular screen size, and orientation. It seems that the app you are working on supports multiple screen sizes. So, the layout should support most screens that help a wider audience use your Android application. 

Techniques to avoid hurdles to optimize screen size & resolution: 

• Utilize view dimensions for dynamic layout resizing.
• Incorporate bitmaps for responsive scaling alongside views.
• Construct a versatile and adaptable user interface (UI).
• Create alternative layouts to enhance flexibility.
• Incorporate small-width qualifiers for diverse screen sizes.
• Modularize fragments by integrating UI components.
• Optimize for HDPI and MDPI resolutions.

Offline Model Optimization

Resolve bad network connectivity, and display available data to fetch required information to enhance Android app performance. Further, using optimal offline mode is best to improve the Android application performance. It is also significant to resolve issues of prolonged data retrieval with the help of caching. You can also enhance the accumulative performance of your Android app, and its user experience using data synchronization through a web server.  Use custom privacy settings to protect sensitive data. In addition, you can prevent usability issues, like complex credentials requests through authentication tokens to get effortless communication for application modules. 

Memory Usage Enhancement

You know Android provides RAM for multitasking. It could become possible that constraints come way through system limitations and background applications. It may lead to resource redundancy. Apart from these limitations, you can enhance your Android app performance and use of memory by fixing issues that are as follows:

Prevent Memory Leaks

Memory leaks come with many tough challenges. Keeping references to inactive activities in your code leads to the retention of their layouts and views in the device’s memory. The non-crucial data usage is easy to fix by releasing unused activity references, and without using pixel retention. 

Things to do about memory leaks: 

• Avoid static references to prevent memory retention.
• Unregister listeners and events when no longer needed.
• Use event bus mechanisms for efficient event handling.
• Opt for static inner classes over non-static for reduced memory impact.
• Conduct comprehensive code quality and standard reviews.
• Emphasize the effectiveness of code reviews in preventing activity leaks based on personal experience.
• Craft memory-efficient code by optimizing resource usage.
• Acquire a deep understanding of your architecture before coding.
• Print logs on callbacks for effective debugging and analysis.
• Employ tools like LeakCanary, MAT, and Eclipse Analyzer for memory profiling.
• Minimize reliance on external libraries to reduce resource overhead.
