重新添加platform

--no-resources可以禁止重新生成icon和splash

ionic cordova platform remove android

ionic cordova platform add android --no-resources

1. icon

提供1024*1024的icon.png图片, 放到根目录下的resources目录下, 执行命令就能生成各个尺寸的图片了

ionic cordova resources --icon

2. splash

先安装插件

$ ionic cordova plugin add cordova-plugin-splashscreen

同样的提供2732*2732的splash.png图片, 执行命名

ionic cordova resources --splash

注意

一定要是真的png图片, 改后缀是无效的, 同时添加了对应的platform才会生成.

修改过splash图片可能会出现打包错误的问题 - Execution failed for task ':mergeDebugResources'.

办法是在platforms\android\build.gradle中加入下面这段

android {

    aaptOptions.cruncherEnabled = false

    aaptOptions.useNewCruncher = false

默认3秒后隐藏会显示一个黑屏. 设置加载好之后才隐藏splash

config.xml中加入下面的配置, SplashShowOnlyFirstTime可以单独给android添加. 参考: ionic开发之splash screen配置问题

    <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" />

λ ionic cordova resources --help

? The Ionic CLI has an update available (3.18.0 => 3.19.0)! Would you like to install it? No

Not automatically updating your CLI.

  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
