无法启动活动组件信息java.lang.RuntimeException：

我正在尝试开发一个Android应用程序。具有java.lang.RuntimeException。我已经在描述和XML文件中创建了Java类代码。我已将活动设置为在运行中显示，但显示为不幸的是，App已关闭。这可能是什么问题？

我的XML文件：

Answer 1

将可绘制图像放在错误的文件夹中时，会发生此问题。例如在drawable-v24中，因此它在API <21上崩溃。

检查welcome图像是否存在于可绘制文件夹中，而不包含任何图像（v-24或v-26）

您可以将welcome粘贴到drawable中，而无需使用任何api版本来解决该问题。

右键单击welcome，然后单击“在文件夹中显示”（在Linux中为文件），然后将其复制并转到上一个文件夹并找到drawable并将其粘贴。

Answer 2

logcat上有一条有趣的行

Caused by: android.content.res.Resources$NotFoundException: Resource "com.ntuumadistributors.ntuuma:drawable/welcome" (7f0700b4) is not a Drawable (color or path): TypedValue{t=0x1/d=0x7f0700b4 a=-1 r=0x7f0700b4}

因此@drawable/welcome可能不是可绘制资源，或者根本不存在或类似资源。

如果您确信这不是您的错，请从菜单（File->Invalidate Caches / Restart）中执行使缓存无效并重新启动
