原來使用原生開發webview外殼,APK有8Mb啓動是毫秒級的,使用Flutter開發類似功能的,APK至少都18Mb起,啓動會有個黑屏(有的顯示白屏),現在怎樣使用圖片代替黑屏呢?以下幾步,如果對應的文件沒有就添加
1、styles.xml文件
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="LaunchTheme" parent="@android:style/Theme.Black.NoTitleBar">
<!-- Show a splash screen on the activity. Automatically removed when
Flutter draws its first frame -->
<item name="android:windowBackground">@drawable/launch_background</item>
</style>
</resources>
2、launch_background.xml
<?xml version="1.0" encoding="utf-8"?>
<!-- Modify this file to customize your launch splash screen -->
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@android:color/black"/>
<!-- You can insert your own image assets here home6爲圖片名稱-->
<item>
<bitmap
android:src="@mipmap/home6"/>
</item>
</layer-list>
3、AndroidManifest.xml 添加、調整內容
android:theme="@style/LaunchTheme"
<meta-data
android:name="io.flutter.app.android.SplashScreenUntilFirstFrame"
android:value="true" />
