【Using English】41 - Core App Quality of Android

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。

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。

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。
