android - 将 minSdkVersion(21) 更改为 (18) < 设备的 API (19) 但项目停止运行

Question

我的真实设备是 API(19)，我阅读了一些帖子并将 minkSdkVersion 从 21 更改

minSdkVersion 21

到 18

minSdkVersion 18 

同步项目并运行但我的项目停止运行。有人知道为什么吗？ (说对不起，音乐已停止)

编辑:这是 Logcat 所说的，请不要告诉我某些代码仅适用于 SdkVerson 21 :(

Answer 1

从您的 LogCat，发现错误。

android.view.InflateException:二进制 XML 文件第 0 行:错误膨胀类 android.widget.ImageView

你可以检查你的图像文件是在 Drawable 还是 Drawable-24

如果它在 Drawable-24 中，移动它到 drawable 文件中。
