Question

我在android中的启动画面前得到一个空白屏幕。我试过解决方案在stackoverflow中给出，但那些正在创建问题。这是我的代码。如果我使用styles.xml主题，那么它说主题是不兼容的 styles.xml

 <?xml version="1.0" encoding="utf-8"?>
  <resources>
  <style name="AppTheme" parent="Theme.AppCompat.Light">
  <item name="android:windowBackground">@drawable/screen</item>
   </style>
 </resources>

AndroidManifest

如果已添加，请在config.xml文件中添加此行，请替换它。

<preference name="SplashMaintainAspectRatio" value="true" />
    <preference name="FadeSplashScreenDuration" value="800" />
    <preference name="SplashShowOnlyFirstTime" value="false" />
    <preference name="SplashScreen" value="screen" />
    <preference name="SplashScreenDelay" value="3000" />
    <preference name="ShowSplashScreenSpinner" value="false" />
