Question

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自己选择的图像。

我已经在这里和其他站点搜索了更简单的错误，但没有得到可靠的解决方法。

我该如何解决错误。

这是错误消息

Answer 1

如果您清楚地看到日志，则会发现异常：

原因：android.content.res.Resources $ NotFoundException：资源不是Drawable（颜色或路径）

这意味着您提供的图像可能位于ex drawable-v24的不同drawble文件夹中（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可绘制文件夹中，为此，首先必须打开项目视图结构，然后执行以下操作：

Project-> app-> src-> main-> res->在这里，您将看到不同的drawable 文件夹

Answer 2

  <ImageView
    android:layout_width="350dp"
    android:layout_height="300dp"
    android:id="@+id/imageView"
    android:src="@drawable/kenya"
    android:layout_below="@+id/textView"
    android:layout_centerHorizontal="true" />

在此代码块中，请检查肯尼亚在可绘制的文件夹中。因为在stacktrace中，原因是：android.content.res.Resources $ NotFoundException：资源不是可绘制对象（颜色或路径）：TypedValue {t = 0x1 / d = 0x7f060058 a = -1 r = 0x7f060058}

Answer 3

您需要将android:src更改为app:srcCompat。还要看一下这个问题：Android: What is the difference between app:srcCompat=" " and android:src=" "?

E / AndroidRuntime：致命异常：主要，导致Android应用崩溃
