1. Sometimes we find that when we set the font size, there is no response, because when the font size in the stylesheet is 12px, the font in the Chinese Chrome browser is still 12px. In this case, we can use HTML {- WebKit – text size- adjust:none; }

2. However – WebKit text size adjust on the body will cause page scaling failure (I don’t know why)

3. Body inherits the style defined in HTML

4. So, give the body WebKit text size- adjust:none That’s it

Comparison between weex and react native

Write on the front

At present, the mainstream applications are generally divided into three categories: native app, web app and hybrid app

Application of three main streams

Native app features:

Good performance

Perfect user experience

High development cost, unable to cross platform

Difficult to upgrade (AUDIT), high maintenance cost

web app features:

Low development cost, fast update, easy version upgrade, automatic upgrade

Cross platform, write once, run anywhere

Unable to call system level API

Temporary entrance, low user retention

Poor performance, poor experience, limited design

Compared with native app, web app experience is limited by the above five factors: network environment, rendering performance, platform characteristics, browser and system limitations.

hybrid app features:

The compromise between native app and web app retains the advantages of native app and web app.

But the performance is poor. Low efficiency of page rendering, drawing interface in WebView, realizing animation, resource consumption are relatively large, limited by technology, network speed and other factors

Snip20161028_ 3.png

In order to solve the above problems, a set of high-efficiency, high-performance cross platform solutions has become a hot topic, there are the following to compare the weex and react native

Basic concepts

weex

Introduction:
weex is an open-source UI framework for building mobile cross platform by Alibaba and June 2016

Features:

1. Lightweight: lightweight, simple syntax, easy to use

2. Extensible: extensible, rich built-in components, extensible API

3. High performance: high performance

Core concept:

Write Once Run Everywhere

Based on JS development framework:

Weex based on vue.js

React Native

Introduction:

Facebook launched an open source cross platform UI framework at the F8 developer conference in March 2015

Core concept: Lean once, write anywhere

Based on JS development framework:

React native based on react

Knowledge development: vue.js And react

Vue:

It is a library to build a data-driven web interface. Vue.js The goal of view component is to realize data binding and view component composition through API as simple as possible

React:

The development of front-end interface based on HTML is becoming more and more complex. Its essential problem can be attributed to how to efficiently reflect the dynamic data from the server or user input to the complex user interface. The react framework from Facebook is a solution to this problem. According to the official website, its starting point is to develop large-scale applications with constantly changing data. Compared with the traditional front-end development, react opens up a quite alternative way to realize the high-efficiency and high-performance development of the front-end interface.

Vue.js Similarities and differences between real and real:

The difference between Vue and react

Similarities and differences between weex and react native

Similarities:

They all adopt web development mode and JS development mode

can debug JS code directly in Chrome;

Both support cross platform development

Can achieve hot reload, while updating the code to see the effect

Differences:

JS engine

What is JS engine

Learning costs

1. Environment configuration:

Reactnative needs to install and configure many dependent tools according to the documents, which is relatively troublesome. Weex can be used after installing cli

2. Vue vs react: the above comparison has been done

There is a certain cost in learning and using react template JSX. Vue is more close to the common way of web development. The template is ordinary HTML, the data binding uses mustache style, and the style uses CSS directly

Community support

Weex’s open source is relatively late, the relevant information on the Internet is relatively small, and the community scale is relatively small

React native community is more active, and there are more projects and materials to refer to

A picture: from rendering time, memory usage, CPU usage, frame rate (GPU can refresh several times per second, high frame rate can get smoother and more realistic animation. The more frames per second (FPS), the smoother the action will be displayed. )

The author of aroma has updated aroma (the latest version is 2.0), so if you use the latest version to do ROM, you may not be able to install the system smoothly! The current solution is to use the signature tool specially customized by the author. There is also the definition and explanation of the interface configuration file (aroma config) command being sorted out (updated from time to time)

when using the new version, you must sign the aroma config and updater script, otherwise, I don’t know the consequences (if you really don’t know this, please test it by yourself)
it’s online signature
with link address:
http://www.amarullz.com/signer/

1、
the starting principle of Arama install
the difference between Arama and general flash packages is that there are more
Arama configupdate binary installers and a resource directory of Arama
the starting process of Arama is as follows:
first, recover will extract update binary from zip firmware package In this step, the same is true for the ordinary firmware package. Next, the ordinary firmware package will directly run update script, which is what we often call the brush script. Unlike it, the brush package of aroma will then parse Arama config (Arama config is a UI configuration file) loads the UI and various commands, and then the dominant power is given to the user. After completing a series of choices, Arama will run update binary install, and then parse and run the commands in update script, and the whole process of machine brushing ends

2、 Aroma install syntax and commands

Let me give you an example to explain the analysis

#The number is an annotation

selectbox(

“Select theme”, # title

“Lease select Install theme that you want to use in this installation test”:

“@ personalize”, # the icon must be referenced with the @ symbol, otherwise it may be wrong, and the icon must be stored in the Arama/icon Folder

Otherwise, there will be mistakes

” theme.prop “, # the selected data will be saved in this path/TMP/aroma/ theme.prop But notice that theme.prop This document is temporary.

#———————————[ SelectboxWithout Group ]———————————-#

#Title | subtitle | initial value#

#——————+———————————————————–+—————#

“Generic”, “Unthemed AROMAInstaller”, 1, #– selected.0 = 1

“MIUI Theme”, “MIUI Theme by mickey-r &amarullz”, 0, #– selected.0 = 2

“ICS Theme”, “Ice Cream Sandwitch by DemonWav& amarullz”, 0, #– selected.0 = 3

“MIUI 4 Theme”, “MIUI 4/ICS Theme by amarullz &Lennox”, 0, #– selected.0 = 4

“Sense Theme”, “HTC Sense Theme by amarullz”, 0 #– selected.0 = 5

#——–[initial value = 0: not selected, 1: selected, 2: checked, 3: invisible]———#

);

The beginning of the command must be in such a format

selectbox(

);

There must be this symbol between each command line

Separate two different commands. When you encounter a text title, you need to use “title” to represent the text

selectbox(

“Theme”,

“sub Theme”

);

This is the format of the selection box

You have to pay attention when writing, otherwise it’s hard to find the wrong one

The first double quotation mark is the title

The second double quotation mark is the subtitle

The third number 1 means that generic is selected by default.

“MIUI Theme”,”MIUI Theme by mickey-r & amarullz”, 0,

“ICS Theme”, “Ice Cream Sandwitch by DemonWav &amarullz”,0,

Here are some common commands for you:

1 loading of the first static screen

splash(

#2000 refers to time. 2000 milliseconds equals 2 seconds

2000,

#Picture reference aroma/ sample.png

“sample”

2 dynamic picture

anisplash(

#Number of consecutive plays

4,

#It is said that the dynamic picture is actually composed of continuous playing pictures

Aroma/splash/a [1.. 6]. Png

“splash/a1”, 500,

“splash/a2”, 30,

“splash/a3”, 30,

“splash/a4”, 30,

“splash/a5”, 30,

“splash/a6”, 30

);

3 agree selection box

agreebox(

#Title

“Terms and Conditions”,

#Subheading

“lease read carefully The AROMAInstaller Terms and Conditions Below.”,

#Icon

“@license”,

#Read from & lt; aroma resource dir & gt/ license.txt )

resread(” license.txt “),

#–Check box text

“I Agree with this Terms andConditions…”,

#–If you don’t check “agree”, it will pop up

“lease check the agreement…”

);

4 menu box

menubox(

“<~ menu.install&gt ;”, “<~ menu.installer&gt ;”, “@apps”, ” azlx.prop “, “<~ install.mr&gt ;”, “<~ install.js .1&>”, “@install”, “<~ install.zdy&gt ;”, “<~ install.js .2&>”, “@apps”, “<~ install.qt&gt You must remember that the last sentence does not need to add this symbol, otherwise there will be grammatical errors);

3、 Chinese culture in aroma install

the hidden content of this post

the Chinese culture of Arama is implemented by stamping a file named. Lang. I will introduce how to use it:

This is the setting in. Lang

See the command in the picture?In fact, the Chinese culture of aroma is very simple. First, set the command in the. Lang file, such as the command in the first line of the figure menu.install= Installation type

Then the settings in aroma config are

“<~ menu.install&gt ;”

This is the setting in aroma config

Arama, please look in the kit
