super optimize app

Examples of small programs, super-loaded instances, and small program instances Preface Before you start developing the application number, take a look at the official "mini-programs" tutorial! (The following content is from the official "applet" Development Guide) This document will take you step by step to create a small program, and you can experience the actual effect of the small program on your phone. The homepage of this applet displays the wel

Maybe there's an app that can provide everything you need, what you don't need, or what you can imagine. But how many apps can really not only satisfy the needs but also provide a good user experience? I believe many apps don't have that kind of power. There are some apps that are so poorly designed that it's hard for users to do things. There are also apps that hang up when the user does something. There are also some

However, loading embedded (embedded) dylib files takes time, so try to merge multiple inline dylib into one to load, or use static archive. It is not recommended to us

Top 10 tips to optimize Android App Performance No matter whether the hammer or eggplant mobile phone keeps popping up, the mobile phone market share of the Android system is still the largest, so the number of apps developed based on Android is also very large. So how can we develop a higher-performance Android App? I believe it is a headache for software deve

1This is a simple analysis of the common memory leaks caused by Activity, in fact, there are many memory leaks, but the rationale is the same. Because of space reasons, here do not introduce too much, and then gradually analyze and learn.Although the memory of mobile phones is getting bigger and larger, memory leaks will not cause OOM as previously due to too little memory. However, excessive memory leaks can still cause memory overflow and affect the user experience, so it is importan

the side of the scrolling edge of the picture may have some impact, so you can scroll when the ImageView do not perform setimage operation, scrolling stopped when the picture is loaded, As the Nsrunloop is in Uitrackingrunloopmode mode when scrolling, you can use the following method to put the settings picture in Nsdefaultrunloopmode mode: UIImage *downloadedimage = ...; [self. Avatarimageview performselector:@selector(setimage:) withobject:downloadedimage afterdelay:0

it is empty, because the memory space of the Bitmap object is loaded, partly Java, and partly C (because the BITMAP allocation is called by JNI, Android's bitmap is implemented using the Skia graphics library, Skia is implemented in C). This recycle () function is the memory release for part C.(2) When constructing adapter, the cached Convertview is not used. Workaround: Construct the adapter in a static holdview manner.This is where memory jitter and memory leaks are discovered, positioned and

, The new request goes to the search interface. This time it is possible that the last request is returned, and the first request is returned, resulting in the result of the first search.How to solve this problem: You can use the SWITCHMAP operator to solve.See how the SWITCHMAP operator is interpreted by the official website:Returnsa NewObservable byApplyinga function that's supply to each item emitted by the source Observable that returns an Observable, and ThenEmitting the ItemsEm
