离子应用程序启动画面未显示

Question

我一直在尝试使用这种配置为我的Ionic App添加一个启动画面,图标确实可以正常工作但splashscreen不起作用.它显示一个空白屏幕,甚至不是cordova默认屏幕splashscreen.

Answer 1

1. 首先尝试读取您的插件:

   $ ionic plugin remove cordova-plugin-splashscreen
   $ ionic plugin add cordova-plugin-splashscreen
   

2. 然后编辑文件夹中的splash图像resources.
3. $ ionic resources --splash在CLI中运行
4. 重建$ ionic build android并运行您的应用

检查Ionic文档 - 图标和启动屏幕图像生成

如果这不起作用,您应该删除并读取遇到问题的平台.

$ cordova platform remove android (or ios)
$ cordova platform add android (or ios)

Answer 2

这是你的答案!!

如果您使用的是Cordova 6.4.0(cordova -v在终端中点击以查看版本),您将面临此问题(构建后不会生成图标和启动画面)

要解决此问题,您有两种选择:

1. 在config.xml 中将单词密度更改为限定符.例如.放

<icon src="resources\android\icon\drawable-ldpi-icon.png" qualifier="ldpi"/>代替<icon src="resources\android\icon\drawable-ldpi-icon.png" density="ldpi"/>.建立项目.将工作.

2. 只需按下npm install -g cordova@6.3.1您的终端即可安装cordova版本6.3.1 .删除然后添加平台,进一步构建它.奇迹般有效!!.

问候!!:p

Answer 3

删除后添加cordova

   $ cordova platform remove android (or ios)
   $ cordova platform add android (or ios)

您将获得一个/res包含图标和启动画面的文件夹.复制内容/res并粘贴platfomrs/android/res,这将取代标准图标和启动画面.

然后构建您的应用程序,您将获得自定义图像.

我使用离子标签模板,没有变化.

Answer 4

我的启动画面也没有出现（Ionic 3）。我发现此链接非常有帮助。中的这些条目config.xml对我有用：

<preference name="SplashMaintainAspectRatio" value="true"/>
<preference name="SplashScreen" value="screen"/>
<preference name="SplashScreenDelay" value="30000"/>
<preference name="AutoHideSplashScreen" value="false"/>
<preference name="SplashShowOnlyFirstTime" value="false"/>
<preference name="FadeSplashScreen" value="false"/>
