每当我使用Android Studio的Vector资源创建带有图标的ImageView时,我就会收到错误 app:srcCompat="@drawable/ic_play"

当我改变app:srcCompat时android:src,错误消失但图标看起来像素化.

两者之间的主要区别是什么

app:srcCompat="@drawable/ic_play"

和

android:src="@drawable/ic_play"

我刚从日食迁移到工作室.我跟着一个博客将项目从eclipse导出到了工作室.该应用程序在棒棒糖中运行良好,并在棒棒糖前设备中抛出以下错误.

仅在工作室中获取此错误.不是在日蚀.
