我正在使用ionic构建一个基于WordPress博客的应用程序。我添加了启动屏幕并在我的设备上打开了它，但它不起作用。我从反构建文件夹中取出了apk文件，但是当我在机器上运行它时，没有显示任何内容。是不是关闭了对档案?xml格式的设置是否正确?

我不知道您是用什么方法生成启动画面的。我用过ionic CLI
通过使用此方法，您可以从源图像自动生成启动屏幕，以创建每个平台所需的每种尺寸。没有必要将每个调整大小和裁剪的图像复制到每个平台的资源目录中。
保存splash.png, splash.psd或splash。. ai文件在Cordova项目根目录下的资源目录下。源图像的最小尺寸应为2208x2208 px。此外，当方向首选项配置设置为横向或纵向模式时，则只生成必要的图像。
$ ionic resources --splash
