由于提到的文档，启动器图标是48 * 48dp

As the doc mentioned,the launcher icon is 48*48dp.

所以我觉得启动器图标应该是144 * 144px对我的Nexus 5结果但是，我研究我的Nexus 5的截图，我发现这几乎是166 * 163px。结果为什么它比144 * 144px更大？

So I think the launcher icon should be 144 * 144px on my nexus 5. But I research a screenshot of my nexus 5,I find it's almost 166* 163px. Why it's bigger than 144*144px?

（P.S与在绘制-xxhdpi文件夹中的144 * 144px图标的应用程序也显示166在发射* 163px）。

(p.s. an app with a 144*144px icon in the drawable-xxhdpi folder is also shows 166* 163px in the launcher.)

这是我的截图：

推荐答案

按照信息有人在谷歌工作的提供，Nexus 5的发射器采用在未来的DPI斗启动器图标，即在Nexus 5将使用一个DPI斗起来XXHDPI - > XXXHDPI，这使得图标192x192。之所以你的测量值小于192是因为启动器图标的图形是不应该填满整个图像。

Per the info provided by someone working at Google, Nexus 5's launcher uses the launcher icon in the next DPI bucket, i.e. on Nexus 5 it will use one DPI bucket up XXHDPI --> XXXHDPI, which makes the icon 192x192. The reason why your measurement is less than 192 is because the launcher icon graphics is not supposed to fill the whole image.
