Performance optimization is the only way for Android programmers to advance. Whether it is during the project development process or during the interview, we will encounter questions about performance optimization.
Performance optimization is a focus but also a difficulty. Many Android learners and developers will face many troubles and unsolvable problems in performance optimization.
Let's take a look at the knowledge points included in Android performance optimization?
360° all-round performance tuning
Program performance optimization:
OOM problem analysis, ANR problem analysis, Crash monitoring scheme, startup speed and execution efficiency optimization project combat, layout detection and optimization, memory optimization, power consumption optimization, network transmission and data storage optimization, APK size optimization, screen adaptation
Development efficiency optimization:
Distributed version control system Git, automated build system Gradle
Frequently Asked Questions about Performance Optimization
Memory problem:
- Memory consumption: memory consumption and memory leaks will affect the performance of the whole machine;
- OOM problem: OOM will affect the stability of the product;
- The memory occupied by the program cannot be released after switching to the background: a large amount of memory occupied indicates that the remaining memory space for other applications is small;
Power consumption problem : hot (power consumption);
Fluency problems : slow startup, page display takes a long time to load in circles, page switching freezes, black and white screen;
In response to the above series of performance problems, Google officially provides a variety of tools to solve various problems in a targeted manner:
Memory problem:
Provides Android Studio's static code detection function, Android Monitor; third-party memory leak analysis tools Leakcanary, MAT;
Power Consumption Issues:
Provides GPU rendering mode, battery-historian, Android Monitor;
Fluency issues:
Provides Android Studio's static code detection function, Android Monitor, HierarchyViewer, StrictMode, transition drawing detection tools, TraceView, etc.;
Summary of performance optimization
Theoretical aspects:
There are many knowledge points involved in Android performance optimization. In addition to common solutions, the underlying principles are also worthy of our in-depth discussion. Here I share with you a 722-page ultra-comprehensive performance optimization knowledge manual: "360-degree omni-directional performance tuning" to help you better learn Android performance optimization.
- Design thinking and code quality optimization
- Program performance optimization
- Development efficiency optimization
- APP performance optimization practice
Android performance optimization - actual combat analysis:
In addition to the theoretical aspect, what is more important is the actual combat of the project. At the same time, I will share with you a practical case of Android performance optimization from various major manufacturers (Tencent, iQiyi, ByteDance, Baidu, JD.com, Alipay...).
