如何从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应用程序对我的服务器执行一些http请求。但是有时候我正在调试在我的开发机器上运行的新api代码。我希望能够在我的代码中传递一些东西（如环境变量），如果现在我可以使用它作为来自android模拟器的api请求的主机名。 / p>

所以我正在寻找一种方式传递如下：

  API_SERVER = http：//10.0.2.2/myapp/ 
  

在我的代码中，我会使用它不知何故，例如：

  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）; 
  

解决方案

我建议使用 productFlavors 。每种风味都可以包含环境特定设置。我只需要一个名为Environment的类，其中包含我需要的所有 public static final String ，每个产品风格包含此类的不同版本，其值为环境。

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.

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

API_SERVER=http://10.0.2.2/myapp/

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);

解决方案

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.
