This blog is the Chinese translation of Google doc Core app quality;
Android users expect high-quality apps. App quality directly influences the long-term success of your app—in terms of installs, user rating and reviews, engagement, and user retention.
Android用户期待高质量的应用。应用的质量直接影响到您的应用是否能取得长期成功，包括安装，用户评分和评价，用户参与度与用户留存率。
This page helps you assess the core aspects of quality in your app, through a compact set of quality criteria and associated tests. All Android apps should meet these criteria.
通过一套简明的质量标准和相关测试，这个页面可以帮助你评估应用质量最核心的方面，所有的Android应用都应该符合这些标准。
Before publishing your apps, test them against these criteria to ensure that they function well on many devices, meets Android standards for navigation and design, and are prepared for promotional opportunities in the Google Play store. Your testing will go well beyond what's described here—the purpose of this document is to specify the essential quality characteristics all apps should display, so that you can cover them in your test plans.
发布应用之前，用过这些标准来测试您的应用，以确保应用功能可以正常运行在多个设备上，确保应用符合Android导航和设计标准，同时为在谷歌Play商店推广做好准备。您的测试范围大可以超过这里的内容，因为本文档的目的是所有应用都应该具备的基本质量特征，因此您可以在测试计划中包括这些内容。
If you're creating apps for other Android devices, such as tablets or TV, there are additional quality guidelines you should consider.
如果您在为平板电报或者电视等其他Android设备开发应用，您需要考虑另外一份质量指南。
Visual design and user interaction
视觉设计和用户交互
These criteria ensure that your app provides standard Android visual design and interaction patterns where appropriate, for a consistent and intuitive user experience.
这些标准可以确保您的应用程序提供了标准的Android视觉设计和适当的交互模式，以实现始终如一的直观用户体验。
| Area | ID | Description | Tests |
|---|---|---|---|
| Standard design | UX-B1 | The app follows Android Design guidelines and uses common UI patterns and icons: 1. The app does not redefine the expected function of a system icon (such as the Back button). 2. The app does not replace a system icon with a completely different icon if it triggers the standard UI behavior. 3. If the app provides a customized version of a standard system icon, the icon strongly resembles the system icon and triggers the standard system behavior. 4. The app does not redefine or misuse Android UI patterns, such that icons or behaviors could be misleading or confusing to users. |

Notifications are persistent only if related to ongoing events (such as music playback or a phone call). 3. Notifications do not contain advertising or content unrelated to the core function of the app, unless the user has opted in. |
CR-11 |
| UX-S2 | The app uses notifications only to: 1. Indicate a change in context relating to the user personally (such as an incoming message), or 2. Expose information/controls relating to an ongoing event (such as music playback or a phone call). |
CR-11 |
| 领域 | ID | 描述 | 测试 |

Functionality
These criteria ensure that your app provides the expected functional behavior, with the appropriate level of permissions.
这些标准确保您的应用以合适的权限等级提供了用户期待的功能行为。
| Area | ID | Description | Tests |
|---|---|---|---|
| Permissions | FN-P1 | The app requests only the absolute minimum permissions that it needs to support core functionality. | SC-4 |
| FN-P2 | The app does not request permissions to access sensitive data (such as Contacts or the System Log) or services that can cost the user money (such as the Dialer or SMS), unless related to a core capability of the app. | SC-4 | |
| Install location | FN-L1 | The app functions normally when installed on SD card (if supported by app). Supporting installation to SD card is recommended for most large apps (10MB+). See the App Install Location developer guide for information about which types of apps should support installation to SD card. |
SD-1 |
| Audio | FN-A1 | Audio does not play when the screen is off, unless this is a core feature (for example, the app is a music player). | CR-7 |
| FN-A2 | Audio does not play behind the lock screen, unless this is a core feature. | CR-8 | |
| FN-A3 | Audio does not play on the home screen or over another app, unless this is a core feature. | CR-1, CR-2 | |
| FN-A4 | Audio resumes when the app returns to the foreground, or indicates to the user that playback is in a paused state. | CR-1, CR-8 | |
| UI and Graphics | FN-U1 | The app supports both landscape and portrait orientations (if possible). Orientations expose largely the same features and actions and preserve functional parity. Minor changes in content or views are acceptable. |
CR-5 |
| FN-U2 | The app uses the whole screen in both orientations and does not letterbox to account for orientation changes.Minor letterboxing to compensate for small variations in screen geometry is acceptable. | CR-5 | |
| FN-U3 | The app correctly handles rapid transitions between display orientations without rendering problems. | CR-5 | |
| User/app state | FN-S1 | The app should not leave any services running when the app is in the background, unless related to a core capability of the app. For example, the app should not leave services running to maintain a network connection for notifications, to maintain a Bluetooth connection, or to keep the GPS powered-on. |
CR-6 |
| FN-S2 | The app correctly preserves and restores user or app state. The app preserves user or app state when leaving the foreground and prevents accidental data loss due to back-navigation and other state changes. When returning to the foreground, the app must restore the preserved state and any significant stateful transaction that was pending, such as changes to editable fields, game progress, menus, videos, and other sections of the app or game. 1. When the app is resumed from the Recents app switcher, the app returns the user to the exact state in which it was last used. 2. When the app is resumed after the device wakes from sleep (locked) state, the app returns the user to the exact state in which it was last used. 3. When the app is relaunched from Home or All Apps, the app restores the app state as closely as possible to the previous state. 4. On Back keypresses, the app gives the user the option of saving any app or user state that would otherwise be lost on back-navigation. |

Setting up a test environment
To assess the quality of your app, you need to set up a suitable hardware or emulator environment for testing.
为了评估应用的质量，您需要搭建一套硬件或者模拟器环境用来测试。
The ideal test environment would include a small number of actual hardware devices that represent key form factors and hardware/software combinations currently available to consumers. It's not necessary to test on every device that's on the market — rather, you should focus on a small number of representative devices, even using one or two devices per form factor.
form factor ==> 机型
理想的测试环境包括少量的真机，这些真机代表着消费者可用的主要机型和软硬件组合。您不必测试市面上的所有设备，而是关注在最优代表性的少量设备上，甚至每个机型只用一到两台设备。
If you are not able to obtain actual hardware devices for testing, you should set up emulated devices (AVDs) to represent the most common form factors and hardware/software combinations.
如果您没有办法获得真机来测试，您需要搭建模拟器的测试环境来代表大多数的机型和软硬件组合。
To go beyond basic testing, you can add more devices, more form factors, or new hardware/software combinations to your test environment. You can also increase the number or complexity of tests and quality criteria.
如果想要比基础的测试更加深入一点，您需要在测试环境中添加更多的设备、更多的机型或者新的软硬件组合。您也可以增加复杂测试和高质量规则的数量。

| 安全 | SC-1 | 查看外部存储空间中存储的所有数据。 |
| SC-2 | 查看加载外部数据是如何被处理的。 | |
| SC-3 | 查看所有定义在Android清单文件中的内容提供者都被设置为合适的安全等级 | |
| SC-4 | 在清单文件中，在运行时，以及设备的设置中(设置>应用信息)，查看应用请求的权限。 | |
| SC-5 | 查看清单文件中所有应用组件是否设置为可导出。所有的组件都要严格地设置为导出属性 | |
| SC-6 | 查看应用的网络安全配置，确保配置失败时不执行Lint检查。 | |
| SC-7 | 对于每一个WebView，导航到一个需要JavaScript的页面。 | |
| SC-8 | 对于每一个WebView，尝试导航到不受控制的站点和内容。 | |
| SC-9 | 声明禁止明文传输的网络安全配置，然后运行应用。 | |
| SC-10 | 运行应用程序，执行所有的核心功能。同时观察设备的日志，确保用户的个人信息不应该被记录。 | |
| Google Play | GP-1 | 登陆Google Play开发者控制台，查看开发者信息，应用描述信息，屏幕截图，置顶大图以及用户反馈。 |
| GP-2 | 下载您的置顶大图和屏幕截图，缩放它们来匹配到您适配的所有设备和机型。 | |

Testing with StrictMode
使用严格模式测试
For performance testing, we recommend enabling [StrictMode](https://developer.android.com/reference/android/os/StrictMode.html) in your app and using it to catch operations on the main thread and other threads that could affect performance, network accesses, file reads/writes, and so on.
对于性能测试，我们推荐应用开启严格模式，用户捕获主线程和其他线程中产生的影响性能，网络访问，文件读写等的操作。
You can set up a monitoring policy per thread using [StrictMode.ThreadPolicy.Builder](https://developer.android.com/reference/android/os/StrictMode.ThreadPolicy.Builder.html) and enable all supported monitoring in the ThreadPolicy using [detectAll()](https://developer.android.com/reference/android/os/StrictMode.ThreadPolicy.Builder.html#detectAll()).
您可以使用StrictMode.ThreadPolicy.Builder在每一个线程都设置监控政策，也可以使用detactAll()方法在ThreadPolicy中开始所有支持的监控。
Make sure to enable visual notification of policy violations for the ThreadPolicy using [penaltyFlashScreen()](https://developer.android.com/reference/android/os/StrictMode.ThreadPolicy.Builder.html#penaltyFlashScreen()).
请确保用penaltyFlashScreen ()在开启方法在ThreadPolicy中开启了违反政策的视觉通知。
