Question

我的真实设备是API（19），我读了一些帖子并从21更改了minkSdkVersion

minSdkVersion 21

到18

minSdkVersion 18

同步项目并运行，但我的项目停止运行。谁知道为什么？（据说对不起，音乐已经停止了）

编辑：这是Logcat所说的，请不要告诉我一些代码只适用于SdkVerson 21 :(

从您的LogCat中找到错误。

android.view.InflateException: Binary XML file line #0: Error inflating class android.widget.ImageView

你可以查看你的图片文件，无论它是Drawable还是Drawable-24

如果它在Drawable-24中，将移动到drawable文件。

可以从Here
