android - E/AndroidRuntime: FATAL EXCEPTION: main, 导致 Android App Crash
问题描述
我正在运行我的 android 应用程序，当我使用图像 @drawable/image（图像大小为 48kb）时它会崩溃，但是当我使用 @mipmap/ic_launcher 时它会运行。我希望能够在开发时使用我选择的图像。
我已经在这里和其他站点搜索过更简单的错误，但我没有得到可靠的修复。
我该如何解决错误。
这是错误消息

解决方案
如果您清楚地看到您的日志，那么您会发现异常：
引起：android.content.res.Resources$NotFoundException: Resource is not a Drawable (color or path)
这意味着您提供的图像可能位于 ex 的不同 drawble 文件夹中drawable-v24（仅适用于 api>=24，但不适用于 api<24），这就是您的应用无法找到该图像的原因，因此您需要将该图像复制到您的drawable 文件夹，首先你必须打开项目视图结构然后通过：
Project->app->src->main->res-> 这里你会看到不同的drawable文件夹
