Question

最近随着Android 7.0.0加速，设备随之而来，我的应用程序开始抛出异常而没有特别的原因。问题是我不知道可能是什么问题 - 我所知道的是，它只发生在三星设备上的Nougat及其绘制一些ImageViews。像Admob或Universal-Image-Loader这样的库可以这样做吗？

无论如何这里是完整的例外 - 希望some1可以帮助我...

Answer 1

您可以检查一下位图在被绘制之前是否被回收了吗？

Answer 2

使用大位图作为TextView的背景时出现此错误。简单地减少Drawable主文件夹中位图的大小就解决了这个问题。我想通过将不同分辨率的位图放在多个Drawable文件夹中可以更优雅地解决这个问题
