Question

showNotificationWithImage(bitmap)

我收到通知，但图像未显示虽然助手工作正常，但为什么其他人没有得到我在api 23中测试过的图像图标却没有显示，所以任何人都可以得到空白图像

我已经发布了带有导入代码的代码，我在做什么错，这正在影响这个问题

调整毕加索的大小，它将开始正常工作

Picasso.get()
                .load(remoteMessage.getData().get("image"))
                .resize(500,500)
                .centerCrop()
                .memoryPolicy(MemoryPolicy.NO_CACHE)
                .networkPolicy(NetworkPolicy.NO_CACHE)
                .into(target));
