画布：试图绘制太大120422400 字节位图

如何解决画布：试图绘制太大120422400 字节位图

您好，我正在尝试将图像从我的应用程序上传到 Firebase，但是当从图库中选择图像但未在图像视图中显示并且该应用程序崩溃后

错误画布：试图绘制过大（120422400 字节）的位图。

只有少数图像具有非常高的分辨率

我曾尝试将硬件加速设为 false，但对我不起作用

还有任何关于如何最小化上传到数据库最大图像分辨率的解决方案应该是 4k

如果您想查看适配器类的代码，请告诉我我会 更新我的问题

这是我的代码

解决方法

这意味着您的图像太大而无法在画布上绘制。

解决方案： 使用任何在线工具（例如 Tiny PNG

）压缩您的图像
