如何在 Android Studio 的运行/调试配置中将参数传递给 Java 代码 [英] How to pass a parameter to the Java code in run/debug configuration from Android Studio

问题描述

我的 android 应用程序向我的服务器发出一些 http 请求.但是，有时我正在调试在我的开发机器上运行的新 api 代码.我希望能够传递一些东西(比如一个环境变量)，所以在我的代码中，如果它存在，我将能够使用它作为来自 android 模拟器的 api 请求的主机名.

My android app does some http requests to my server. However sometimes I am debugging the new api code that runs on my development machine. I would like to be able to pass something (like an environment variable) so in my code, if it's present I would be able to use that as the hostname for the api requests from the android emulator.

所以我正在寻找一种方法来传递类似的东西:

So I'm looking for a way to pass something like:

API_SERVER=http://10.0.2.2/myapp/

在我的代码中我会以某种方式使用它，例如:

and in my code I would use it somehow, for example:

final static String API_SERVER_REAL = "http://example.com/";
final String apiServerOverride = System.getenv("API_SERVER");
final String API_SERVER = (null != apiServerOverride && !apiServerOverride.isEmpty() ? apiServerOverride : API_SERVER_REAL);

推荐答案

我建议使用 productFlavors.每种风格都可以包含特定于环境的设置.我只是有一个名为Environment"的类，它包含我需要的所有 public static final String 并且每个产品风格都包含此类的不同版本，并为环境设置了值.

I suggest using productFlavors. Each flavor can contain environment specific settings. I simply have a class called 'Environment' which contains all the public static final Strings that I need and each product flavor includes an different version of this class with the values set for the environment.
