ionic生成全尺寸icon和splash

http://www.jianshu.com/p/eda363eb28d3

從新添加platform

--no-resources能夠禁止從新生成icon和splash

ionic cordova platform remove android
ionic cordova platform add android --no-resources

1. icon

提供1024*1024的icon.png圖片, 放到根目錄下的resources目錄下, 執行命令就能生成各個尺寸的圖片了

ionic cordova resources --icon

2. splash

先安裝插件

$ ionic cordova plugin add cordova-plugin-splashscreen

一樣的提供2732*2732的splash.png圖片, 執行命名

ionic cordova resources --splash

注意

必定要是真的png圖片, 改後綴是無效的, 同時添加了對應的platform纔會生成.

修改過splash圖片可能會出現打包錯誤的問題 - Execution failed for task ':mergeDebugResources'.

辦法是在platforms\android\build.gradle中加入下面這段

android {
    aaptOptions.cruncherEnabled = false
    aaptOptions.useNewCruncher = false

默認3秒後隱藏會顯示一個黑屏. 設置加載好以後才隱藏splash

config.xml中加入下面的配置, SplashShowOnlyFirstTime能夠單獨給android添加. 參考: ionic開發之splash screen配置問題

<preference name="SplashScreenDelay" value="3000" />
    <preference name="ShowSplashScreenSpinner" value="false" />
    <preference name="AutoHideSplashScreen" value="false" />
    <preference name="FadeSplashScreen" value="false" />
    <preference name="SplashMaintainAspectRatio" value="false" />
    <preference name="SplashShowOnlyFirstTime" value="true" />

  ionic cordova resources - Automatically create icon and splash screen resources

    Ionic can automatically generate perfectly sized icons and splash screens from source images (.png, .psd, or .ai)
    for your Cordova platforms.

    The source image for icons should ideally be at least 1024×1024px and located at resources/icon.png. The source
    image for splash screens should ideally be at least 2732×2732px and located at resources/splash.png. If you used
    ionic start, there should already be default Ionic resources in the resources/ directory, which you can overwrite.

    You can also generate platform-specific icons and splash screens by placing them in the respective
    resources/<platform>/ directory. For example, to generate an icon for Android, place your image at
    resources/android/icon.png.

    By default, this command will not regenerate resources whose source image has not changed. To disable this
    functionality and always overwrite generated images, use --force.

    For best results, the splash screen's artwork should roughly fit within a square (1200×1200px) at the center of the
    image. You can use https://code.ionicframework.com/resources/splash.psd as a template for your splash screen.

    ionic cordova resources will automatically update your config.xml to reflect the changes in the generated images,
    which Cordova then configures.

    Cordova reference documentation:
    - Icons: https://cordova.apache.org/docs/en/latest/config_ref/images.html
    - Splash Screens: https://cordova.apache.org/docs/en/latest/reference/cordova-plugin-splashscreen/

    This command uses Ionic servers, so we require you to be logged into your free Ionic account. Use ionic login to
    login.

  Usage:

    $ ionic cordova resources [<platform>] [options]

  Inputs:

    platform ................. The platform for which you would like to generate resources (android, ios)

  Options:

    --force, -f .............. Force regeneration of resources
    --icon, -i ............... Generate icon resources
    --splash, -s ............. Generate splash screen resources

  Examples:

    $ ionic cordova resources
    $ ionic cordova resources ios
    $ ionic cordova resources android

歡迎頁圖片規格, 都是.png的圖片
