字幕翻译：

1

00:00:00,500 –> 00:00:03,050

我们在今年的谷歌 I/O 大会上展示了

We showed you a sneak peek of Android Instant

2

00:00:03,050 –> 00:00:04,920

Android Instant Apps

Apps at Google I/O this year.

3

00:00:04,920 –> 00:00:08,000

我们正致力于在不需要安装的情况下

We’re working to evolve Android apps to be able to run

4

00:00:08,000 –> 00:00:10,350

让 Android 应用能够运行起来

instantly without installation.

5

00:00:10,350 –> 00:00:12,402

我叫 Suresh 是 Google 的一名产品经理

I’m Suresh, a Product Manager at Google,

6

00:00:12,402 –> 00:00:13,860

我想告诉你为什么

and I want to tell you why we’re so

7

00:00:13,860 –> 00:00:18,140

我们对于 Android Instant Apps 的诞生如此激动 同时展示一下它是如何使用的

excited about Android Instant Apps and show you how it works.

8

00:00:18,140 –> 00:00:21,440

像你一样的开发者已经构建好了很棒的 Android 应用

Developers like you have built amazing Android apps.

9

00:00:21,440 –> 00:00:24,920

Android 应用以平滑动画或者其他形式

Android apps unleash the full power of Android devices,

10

00:00:24,920 –> 00:00:27,800

将相机或 GPS 无缝结合起来

seamlessly combining the camera, the GPS,

11

00:00:27,800 –> 00:00:30,080

由此激发了 Android 设备的全部潜能

with smooth animations and more.

12

00:00:30,080 –> 00:00:32,250

但是你告诉我们你希望能够让

But you tell us you wish you could bring users

13

00:00:32,250 –> 00:00:34,150

用户更快的接入你的应用

into your apps more quickly.

14

00:00:34,150 –> 00:00:37,220

通常你仅仅需要点击链接就可以直接登入到一个网页上

With the web, you can tap a link and land on a web page.

15

00:00:37,220 –> 00:00:39,890

这仅仅需要一次点击外加几秒钟

It takes one tap and just a few seconds.

16

00:00:39,890 –> 00:00:41,850

但是如果我没有预先安装应用

But if I don’t have the app installed,

17

00:00:41,850 –> 00:00:43,710

却想在应用中达到同样的效果

getting to the same place in the app

18

00:00:43,710 –> 00:00:46,690

则需要很多次的点击外加几分钟

can take many taps and a few minutes.

19

00:00:46,690 –> 00:00:50,200

我们想要在应用中帮你给更多用户

We want to help you deliver the rich and immersive experiences

20

00:00:50,200 –> 00:00:52,760

提供丰富与沉浸式的体验

in your Android apps to more users.

21

00:00:52,760 –> 00:00:57,400

所以在 Instant Apps 中 我们尝试完全去除掉安装应用时所带来的槽糕用户体验

So at Instant Apps, we try to get rid of install friction completely.

22

00:00:57,400 –> 00:00:59,240

让我给你展示一下它是如何做到的

Let me show you what this looks like.

23

00:00:59,240 –> 00:01:02,510

譬如说我的朋友发给我一个 Buzzfeed Video 上

Let’s say my friend [? Fika’s ?] sent me a link to tasty recipes

24

00:01:02,510 –> 00:01:04,019

食谱的链接

on Buzzfeed Video.

25

00:01:04,019 –> 00:01:06,700

但是我的手机上没有安装 Buzzfeed Video

I don’t have the Buzzfeed Video app on my phone.

26

00:01:06,700 –> 00:01:09,190

当我点击链接后 却能直接跳到

When I tap the link, I am taken directly

27

00:01:09,190 –> 00:01:12,160

应用中的“美食”频道

to the Tasty Channel in the Android app.

28

00:01:12,160 –> 00:01:14,910

我可以看到许多制作不同食谱的视频

I see a stream of videos showing how to make different recipes.

29

00:01:14,910 –> 00:01:17,460

而且视频还是自动播放的

This video even starts playing automatically.

30

00:01:17,460 –> 00:01:19,420

这是一个很酷的应用 不是吗

It’s an awesome Android app, isn’t it?

31

00:01:19,420 –> 00:01:21,760

我甚至自始至终都没有安装过它

And I didn’t even have to install it.

32

00:01:21,760 –> 00:01:26,020

应用能够快速启动是因为它被模块化了

The app opened up so quickly because it’s been split into modules.

33

00:01:26,020 –> 00:01:28,960

只有必须要展示在屏幕上的那部分代码

Only the code necessary to display these screens

34

00:01:28,960 –> 00:01:31,790

才会被下载下来并且立刻运行

was downloaded and run on the fly.

35

00:01:31,790 –> 00:01:34,190

如果我想把 Buzzfeed Video 添加到我的主屏幕上

If I want to add Buzzfeed Video to my home screen,

36

00:01:34,190 –> 00:01:37,650

只需要在这里轻轻一点（下载整个应用）就可以了

it’s simple to install the full app right here.

37

00:01:37,650 –> 00:01:39,670

让我们再看另一个例子

Let’s take a look at another example.

38

00:01:39,670 –> 00:01:42,780

B&H Photo and Video （相机网上商城）有一个非常美观的 Android 应用

B&H Photo and Video has a beautiful Android app,

39

00:01:42,780 –> 00:01:45,020

但是我没有必要把它装在我的手机上

but I don’t necessarily have it on my phone

40

00:01:45,020 –> 00:01:47,180

因为我不可能天天买相机

because I don’t shop for cameras every day.

41

00:01:47,180 –> 00:01:49,950

有了 Instant Apps 这再也不是问题了

With Instant Apps, this is not a problem.

42

00:01:49,950 –> 00:01:54,110

比如说我用 Google 搜索某一款相机并且看到了 B&H 上一个不错的报价

Let’s say I search for a camera and see an offer from B&H that I like.

43

00:01:54,110 –> 00:01:57,350

轻轻一点 应用打开

With one tap, the app opens up, deep linked right

44

00:01:57,350 –> 00:01:59,060

会直接链接到我想要的相机页面

to the camera I want to buy.

45

00:01:59,060 –> 00:02:01,720

从技术上来说 只有通过深层链接到的

Well, technically, it’s deep linked right to the Android

46

00:02:01,720 –> 00:02:04,740

对应产品展示页面的那部分代码

activity that B&H wrote that displays this product,

47

00:02:04,740 –> 00:02:08,340

是需要 Google Play 下载的

and that’s all the code that Google Play needed to download.

48

00:02:08,340 –> 00:02:10,419

我可以向右滑动看到更多的相机介绍

I can swipe right to read more about the camera,

49

00:02:10,419 –> 00:02:12,860

现在我把它放到购物车里

but I’m going to go ahead and add it to my cart.

50

00:02:12,860 –> 00:02:17,180

结账时 Android Pay 会正常运行 仿佛我已经安装过这个应用

At checkout, Android Pay works just like if I had the app installed.

51

00:02:17,180 –> 00:02:21,380

有了 Android Instant Apps 我可以自动登陆并直接付款

With Android Instant Apps, I’m already signed in and ready to pay.

52

00:02:21,380 –> 00:02:24,040

这只需要两次点击 而不是两分钟

It takes two taps, not two minutes.

53

00:02:24,040 –> 00:02:27,520

最后 让我们再来看一个 Instant Apps 如何在现实生活中

Finally, let’s take a look at an example of how Instant Apps can

54

00:02:27,520 –> 00:02:29,910

应用的例子

be useful in the real world.

55

00:02:29,910 –> 00:02:32,470

我走向停车计时器 需要付款

I walk up to a parking meter, and I need to pay.

56

00:02:32,470 –> 00:02:34,690

我手机上并没有停车软件

I don’t have the parking app on my phone.

57

00:02:34,690 –> 00:02:38,590

但通过 NFC 功能 只要我把手机贴近计时器

But what if I could tap my phone on the meter, and with NFC,

58

00:02:38,590 –> 00:02:40,980

就会立刻跳出停车应用的界面

it brings up the parking app immediately.

59

00:02:40,980 –> 00:02:42,960

我只需要选择停车时长

I choose how long I want to park and pay

60

00:02:42,960 –> 00:02:46,250

然后用 Android Pay 付款就可以了 简单方便

with Android Pay– simple and easy.

61

00:02:46,250 –> 00:02:48,950

看 这就是 Android Instant Apps （的特性）

So there you go– Android Instant Apps.

62

00:02:48,950 –> 00:02:51,100

对用户来说 从运行应用

As a user, it is totally seamless,

63

00:02:51,100 –> 00:02:55,300

到登陆 到付款 都是极为方便的

from launching the app, to signing in, to making payments.

64

00:02:55,300 –> 00:02:58,140

现在我们来聊聊如何构建 Android Instant Apps

Now let’s talk about how to build Android Instant Apps.

65

00:02:58,140 –> 00:03:01,360

好消息是现有的应用

The great news is that you can enable this functionality

66

00:03:01,360 –> 00:03:04,230

在升级后就可以支持此功能

by upgrading your existing Android app.

67

00:03:04,230 –> 00:03:06,150

Instant Apps 并非是一个独立的新应用

This is not a new separate app.

68

00:03:06,150 –> 00:03:09,680

你可以继续使用相同的 Android API 源码

You continue using the same Android APIs, the same source

69

00:03:09,680 –> 00:03:13,060

和现有的 Android Studio 项目

code, and your existing Android Studio project.

70

00:03:13,060 –> 00:03:14,520

你只需要不到一天的时间

It can take less than a day of work

71

00:03:14,520 –> 00:03:17,440

具体取决于你的应用是如何架构的

to get set up, depending on how your app is built.

72

00:03:17,440 –> 00:03:21,320

你可以通过模块化你的应用使得它能够接入 Instant Apps

You enable your app to run instantly by modularizing it.

73

00:03:21,320 –> 00:03:23,970

这样 Google Play 就可以只下载必要的部分

This allows Google Play to download only the parts that

74

00:03:23,970 –> 00:03:27,230

从而使用户体验更加的

are needed, on the fly, to make the user experience feel

75

00:03:27,230 –> 00:03:29,050

快速与便捷

fast and snappy.

76

00:03:29,050 –> 00:03:31,430

最重要的是 作为开发者的你

Most importantly, you, as the developer,

77

00:03:31,430 –> 00:03:35,460

可以完全掌握应用的用户体验

are in full control of your app’s user experience.

78

00:03:35,460 –> 00:03:38,440

Instant Apps 能适配到的 Android 版本最老为 Jelly Bean

Instant Apps is compatible with Android versions going

79

00:03:38,440 –> 00:03:42,530

这使得你的应用可以让超过十亿的用户

all the way back to Jelly Bean, making your app a tap away

80

00:03:42,530 –> 00:03:45,040

仅在轻轻一触之间便可使用

for over a billion users.

81

00:03:45,040 –> 00:03:47,010

我们非常激动于 Instant Apps 所带来的无限可能

We’re excited about the opportunities

82

00:03:47,010 –> 00:03:48,670

并愿意

this will open up and want to get

83

00:03:48,670 –> 00:03:51,180

将它交到像你一样的开发者手中

this in the hands of developers like you.

84

00:03:51,180 –> 00:03:54,680

但这毕竟是一个巨大的改变 我们想确保它走在正确的道路上

But this is a big change, and we want to get it right.

85

00:03:54,680 –> 00:03:57,270

我们现在正在和一小部分开发者共同努力

So we’re working with a small set of developers now,

86

00:03:57,270 –> 00:03:59,910

之后将会逐步推广

and we’ll be gradually expanding access.

87

00:03:59,910 –> 00:04:04,010

我们将于明年推出 Instant Apps 使其与用户见面

We’ll be rolling out Instant Apps to users over the next year.

88

00:04:04,010 –> 00:04:06,680

如果你有兴趣升级你的应用接入 Instant Apps

If you are interested in upgrading your app to run
