離子閃屏未加載

Question

我已經檢查並仔細檢查了堆棧溢出，以找到關於此問題的答案，但我確實找不到。 我正在使用離子框架構建應用程序，盡管我以前從未遇到過此問題，但由於某些原因，啟動畫面無法正常工作。 我只是得到一個完全白屏，然后在加載初始視圖之前有一個延遲。 這是我到目前為止所采取的步驟。

我通過添加splash.png和icon.png圖像並在終端中使用“ ionic resources”命令生成了離子資源（此方法工作正常，並且生成資產，圖標確實有效）

通常，這足以根據默認的離子框架設置顯示啟動屏幕，但是沒有運氣。

我的配置xml文件如下所示

我仔細檢查過所有指向圖像的路徑是否正確。 我在構建期間沒有收到任何錯誤，在進行仿真時也沒有收到任何錯誤。 我什么都沒顯示。 白屏確實顯示了3秒鍾，所以我很確定應用程序找到相關的啟動圖像會出現問題。

Answer 1

1. 轉到：/usr/local/lib/node_modules/ionic/node_modules/ionic-app-lib/lib/resources.js
2. 將cacheImages屬性更改為false
3. 刪除Android平台
4. 重新添加android平台
5. 再生資源

並在config.xml中確保代碼配置如下：

<icon src="resources/android/icon/drawable-ldpi-icon.png" density="ldpi"/>
<splash src="resources/android/splash/drawable-port-xxxhdpi-screen.png" density="port-xxxhdpi"/>
<preference name="SplashScreen" value="screen"/>

Answer 2

您需要更改<platform>部分，使其文件名為screen.png ，如下所示。 您的screen.png路徑不正確無論何時使用SplashScreen以外的其他任何名稱，都需要更新配置： https : //cordova.apache.org/docs/en/3.1.0/cordova/splashscreen/splashscreen.html #android

<platform name="android">

  <splash src="platform-resources/android/res/drawable-ldpi/screen.png" density="ldpi" />

  <splash src="platform-resources/android/res/drawable-mdpi/screen.png" density="mdpi" />

  <splash src="platform-resources/android/res/drawable-hdpi/screen.png" density="hdpi" />

  <splash src="platform-resources/android/res/drawable-xhdpi/screen.png" density="xhdpi" />

  <splash src="platform-resources/android/res/drawable-xxhdpi/screen.png" density="xxhdpi" />
</platform>
