图像管理和缩放
我正在开发动态壁纸，我想知道如何管理高质量图像。顺便说一句，我对 Android 开发还很陌生。 我有 2 个问题：
1）我用于创建壁纸的图像是矢量图像（2560w x 1600h，32 位，10mb），非常脆且具有非常高的分辨率。我尝试将它作为壁纸，它看起来非常棒（在我的平板电脑上）。我将它放在 drawable 文件夹中。这会生成一个高维 .apk 文件 (9 Mb)。 拥有这么大的文件放大 apk 尺寸是否可以，还是尽可能减小它是一个好习惯？
2) 从 Engine 类构建我的壁纸时 < strong>我想知道，将上面的图像设置为壁纸后，将其缩放到与屏幕尺寸无关的 XY 位置的最佳做法是什么。
PS：我发现最完美的是当您尝试将图像设置为壁纸时，Android 使用默认系统。在这种情况下系统会做什么？
谢谢:)
I am developing a live wallpaper and I would like to know how to manage high quality images. I am quite new to android development by the way.
I got 2 questions:
1)The image I use for wallpaper creation is a vector image (2560w x 1600h, 32bit, 10mb exactly), very crispy and with really high resolution. I tried it as a wallpaper and it looks just fantastic (on my tablet). I placed it in the drawable folder. This results in a high dimension .apk file (9 Mb). Is it ok to have files this big enlarge apk dimension or it is a good practice to reduce it as much as possible?
2)When building my wallpaper from the Engine class i'd like to know, after setting the above image as a wallpaper, what is the best practice to scale it fitting XY independant of screen sizes.
PS: What i found to be perfect was the default system android use when you attempt to set an image as wallpaper. What does the system do in that case?
Thanks :)

1.）据我所知，没有任何 Android 设备支持大于 1280x760 的分辨率，因此使用比这更大的图像并不是一个好的做法，因为它们会毫无意义地使用大量空间。
2.) DisplayMetrics 类包含与此问题相关的所有内容。
1.)Since no android device supports resoultion bigger than 1280x760 of what I know, it is not a good practice in having images with bigger size than this as they use a lot of space for nothing.
2.)The DisplayMetrics class has everything you need related to this problem.
