设置安卓启动页报错

• 首先设置安卓启动页

• 在android/app/src/main/AndroidManifest.xml中添加这一行

• 然后找到android/app/src/main/res/drawable/launch_background.xml

<meta-data android:name="io.flutter.embedding.android.SplashScreenDrawable" android:resource="@drawable/launch_background" />

• 添加代码

<!-- You can insert your own image assets here -->
     <item>
    <!-- android:gravity="center" -->
        <bitmap
         android:src="@drawable/splash"/>
    </item> 

• 如果在这里不行就将代码放在同级的另一个drawable-v21文件夹中,然后将图片放在drawable文件夹中

• 结果运行之后发现报错图片太大，在网上压缩图片从2.9MB到400K都还是报错，最后在stackflow上找到解决办法

Move your image in the drawable to mipmap-xxhdpi.Your image is in bitmap format so you should put your image in mipmap folder,then it will work

• 将图片从drawable中移动到mipmap-xxxhdpi中

• 然后更改drawable或者drawable-21文件夹中launch_background.xml的代码为新的地址

<item>
    <bitmap android:src="@mipmap/splash" />
</item>

• 就好啦
