当我使用 Android Oreo 或更高版本的手机时，不会出现此错误。 但是，当我在具有 3GB RAM 的 Android Marshmallow 中尝试此应用程序时，会弹出此错误。

我在谷歌查找时尝试过的事情是：

1) 新增 com.android.support:design:28.0.0

2) 新增 android:largeHeap="true"

3) 将我所有的可绘制项目复制到 drawable-v24 文件夹中

上述方法没有给出任何积极的结果。

Answer 1

看来您的可绘制资源太大以至于没有足够的 memory 来加载它。

首先，如果它不是那么高分辨率，我建议您为每个屏幕像素密度提供不同的图像。 查看此（支持不同的像素密度）以获取更多信息。

其次，如果您无论如何都想加载高分辨率图像，则应考虑不将其完全加载到 memory。 查看此（有效加载大位图）以获取有关有效加载大图像的更多信息。
