Android SplashScreen API在Android≤9设备上崩溃问题求助

• 应用闪屏迁移至新SplashScreen API后，Android 13设备运行正常，但Android 9模拟器启动即崩溃。
• 核心崩溃错误：

Caused by: java.lang.IllegalArgumentException: R is not a valid verb. Failure occurred at position 2 of path: STRING_TOO_LARGE

• 替换为简单SVG图标后模拟器可正常运行，但无法获取路径更短的目标SVG Logo，寻求Android 9及以下设备的解决办法。

1. 拆分并优化SVG路径 #

Android 9及以下的VectorDrawable对单条路径长度有解析限制，可通过SVG编辑工具（如Figma、Inkscape）处理：

• 打开目标SVG，定位到报错的长路径
• 将单条长路径拆分为多条独立子路径
• 删除冗余路径指令（如重复的闭合指令、过度精确的小数点），保留核心路径信息

2. 分版本提供图标资源 #

针对不同系统版本提供对应格式的图标，绕过旧系统的SVG解析问题：

• 在res/drawable-v28/目录下保留原SVG图标，供Android 10及以上设备使用
• 在res/drawable/目录下放置对应分辨率的PNG格式图标，适配Android 9及以下设备
• 确保SplashScreen配置中引用的drawable资源会自动适配资源目录

3. 升级兼容库优化解析 #

更新androidx相关依赖，利用VectorDrawableCompat的兼容解析逻辑：

• 在项目的build.gradle（Module级别）中更新依赖版本：

implementation 'androidx.appcompat:appcompat:1.6.1'
implementation 'androidx.core:core-ktx:1.12.0'

• 若直接在布局中引用图标，使用app:srcCompat替代android:src属性

4. 压缩SVG文件 #

使用SVGO等工具压缩SVG，减少路径长度和冗余代码：

• 运行压缩命令（需提前安装SVGO）：

svgo input.svg -o output.svg

• 压缩后验证图标视觉效果无变化，再替换原资源
