Question

根据新文物docs，我必须将其API密钥保存在名为newrelic.properties的文件中，并在主类的onCreate上使用它。如何避免两次存储此密钥（newrelic.properties和Constants文件）？如何获取存储在newrelic.properties文件中的api？

使用新的Relic API密钥的地方：

MainActivity onCreate：

NewRelic.withApplicationToken("GENERATED_TOKEN").start(this.getApplication());

在项目名称/应用路径中文件newrelic.properties

com.newrelic.application_token=GENERATED_TOKEN

制作实用程序类AssetsPropertyReader：

public class AssetsPropertyReader {
   private Context context;
   private Properties properties;

   public AssetsPropertyReader(Context context) {
          this.context = context;
          /**
           * Constructs a new Properties object.
           */
          properties = new Properties();
   }

   public Properties getProperties(String FileName) {

          try {
                 /**
                  * getAssets() Return an AssetManager instance for your
                  * application's package. AssetManager Provides access to an
                  * application's raw asset files;
                  */
                 AssetManager assetManager = context.getAssets();
                 /**
                  * Open an asset using ACCESS_STREAMING mode. This
                  */
                 InputStream inputStream = assetManager.open(FileName);
                 /**
                  * Loads properties from the specified InputStream,
                  */
                 properties.load(inputStream);

          } catch (IOException e) {
                 // TODO Auto-generated catch block
                 Log.e("AssetsPropertyReader",e.toString());
          }
          return properties;

   }

}

然后像这样使用它：

AssetsPropertyReader assetsPropertyReader = new AssetsPropertyReader(context);
Properties p = assetsPropertyReader.getProperties("MyStringsFile.properties"); //here 'MyStringsFile.properties' is the name of the file


Toast.makeText(context, p.getProperty("MyBlog"), 1).show(); //'MyBlog' is the key we want value for

我发现的解决方案基于以下主题： access Properties file located in app folder in src file in android

Android - How To Get Flavor's ApplicationId

https://discuss.newrelic.com/t/multiple-flavors/12374/15

1 / app / build.gradle

在android {...}插件之前，添加：

// Check if new relic file exists
Properties props = new Properties()
try {
  props.load(file('newrelic.properties').newDataInputStream())
} catch (Exception ex) {
  throw new GradleException("Missing newrelic.properties file on /app path.")
}

2 / app / build.gradle

 productFlavors {
    production {
      dimension = "datatype"
      buildConfigField "String", "NEW_RELIC_API_KEY", "\"${props.getProperty("com.newrelic.application_token")}\""
    }
}

3 /您的应用中的任何班级。在我的情况下是MainActivity

if(isProductionFlavor()) {
    NewRelic
     .withApplicationToken(BuildConfig.NEW_RELIC_API_KEY)
     .start(this.getApplication())
}

保存和使用新Relic API密钥的正确方法
