每周我们打开提示框，分享一些最好的读者提示。本周我们将关注android浏览器的缩放、caffeine power naps以及android设备上的定制引导屏幕。

双击可放大android浏览器

迈克写了他的新发现：

This might be old news for Android veterans but I just discovered this trick: When browsing on the Android web browser you can double tap to immediately zoom in to 100% view on the spot you double tapped. It’s super handy for a quick swoop in on a webpage that has rendered too **all on the mobile screen. Double tap again and it zooms right back out to the original (full screen) size.

你说得对，迈克，虽然这个提示对于Android老手来说可能很老了，但我想可以肯定地说，每个Android用户都有自己的“啊哈！“当他们发现这个小小的妙计时。你通过分享来支付。

浓缩咖啡小憩，让你保持高度警觉

亚历克斯在信中提到了他在繁忙的日程中保持警惕的建议：

OK guys, this isn’t exactly a software hack (more of a wet-ware hack really) but it’s really been helping me out lately so I figured I’d write in. Everybody knows that a little power nap can really help you get through the day but have you tried a caffeine-fueled power nap? It sounded crazy but a guy I work with (who also has a wild schedule like me) swore by it so I tried it. Here’s how it works. You slug back a cup or coffee or a shot of espresso and then immediately take a 20 minute power nap. When you wake up you feel crazy refreshed. At first I was sure I was just imagining the effect but when I Googled it I found research that supports “caffeine napping”.

有时候，软件提示和软件提示一样有用，亚历克斯。我们以前也用过***能量午睡法，效果不错。没有什么能比得上从强力午睡中得到提神和一杯***来帮助你振作的双重打击了。

如何更改android启动屏幕

Elyse在文章中提到了一种在Android**上交换启动屏幕的技术：

I like customizing my Android phone and as much as I liked the Cyanogen splash screen that appeared after I rooted/upgraded my phone I wanted to tweak it. I found this video and guide and followed along and now I’ve got a custom splash screen. This was my first foray into doing any deep customization and it went really **oothly!

定制启动屏幕很有趣；我们的第一个启动屏幕定制是多年前在Windows**上进行的。我们想摆脱恼人的Sprint电视广告/标识，它在每次**重启时都会溅起水花（在早期的Windows mobiles时代，这是经常发生的事情）。感谢您在爱丽舍的来信！
