How to read local.properties android in java files

I want to add custom fields in local.properties like

debug.username=test123
debug.password=abcd1234

can add .properties files in assets folder and read that easily.

Resources resources = context.getResources();
AssetManager assetManager = resources.getAssets();
Properties properties = null;        
InputStream inputStream = assetManager.open(fileName);
properties = new Properties();
properties.load(inputStream);

But don't want to do this. As i want every team member of our to use local.properties to specify there custom attribute. which is not the part of version control system.

So how to read local.properties placed in the root folder of gradle based android project in java files at runtime?

Here's a variant of the other solutions, stripped down to the essentials:

local.properties:

username=test123
password=abcd1234

build.gradle

android {
    ...
    defaultConfig {
        ...
        Properties properties = new Properties()
        properties.load(project.rootProject.file('local.properties').newDataInputStream())
        buildConfigField "String", "USERNAME", "\"" + properties.getProperty('username') + "\""
        buildConfigField "String", "PASSWORD", "\"" + properties.getProperty('password') + "\""
    }
}

Java:

String userName = BuildConfig.USERNAME;

I know that this is an old question but I recently encountered the same thing and I thought I'd share my solution:

  1. Set the value in your local.properties file.
  2. Read the value in your Gradle build script and set it to a BuildConfig constant.
  3. Access the BuildConfig constant in your Java code.

local.properties

username=myUsername

build.gradle:

def getUsername() {
    Properties properties = new Properties()
    properties.load(project.rootProject.file('local.properties').newDataInputStream())
    return properties.getProperty("username");
}

android {
    defaultConfig {
        buildConfigField "String", "USERNAME", "\""+getUsername()+"\""
    }
}

Example Java class:

package your.package.name;

class MyClass {
    String getUsername() {
        return BuildConfig.USERNAME; // Will return "myUsername"
    }
}

Properties properties = new Properties();
InputStream inputStream = 
this.getClass().getClassLoader().getResourceAsStream("fileName.properties");
properties.load(inputStream);
Username=properties.getProperty("username");      
password=properties.getProperty("password");

More detailed answer is here http://pillsfromtheweb.blogspot.in/2014/09/properties-file-in-android.html

and for asset use this code

        AssetManager assetManager = getAssets();
        InputStream inputStream = null;
        try {
            inputStream = assetManager.open("fileName.properties");
            properties.load(inputStream);
            String Username = properties.getProperty("username");
            String password = properties.getProperty("password");
        }
        catch (IOException e){
            Log.e("message: ",e.toString);
        }
