android open a .properties file from project

Question

I have a file defined next to the default.properties, AndroidManifest.xml, called my_config.properties. my question is. how do open this file in my class?

if i move it to the class package i can read it using the folowing code:

 Properties configFile = new Properties();
    try {
        configFile.load(MyConstantsClass.class.getResourceAsStream("my_config.properties"));
    } catch (IOException e) {
        e.printStackTrace();
    }

but in this case the file needs to be inside the same package as the class i use this snippet in. how do i read from it when its defined like in the beggining of my question? Thank you.

You can only open files from Android that are included in your APK, the current location of the my_config.properties will not be included in there. I would suggest that the right place for this kind of file would be your "assets" directory and you have to use the correct class to access it.

thanks. but is there any chance that i can define something like this in build time. i don't need those properties in the apk. i just need to compile the app according to a prod/test profile. for example i will have one constant defined true as test and false as prod. i need this because i use a different base url for the production and test server. is there a way this sort of thing can be handled better than using if clauses, manually going over the code before release to make all the changes for production or in a .java class? – DArkO May 17 '11 at 11:33

In that case if you want to know if you are on a production or development environment then you would be better off looking at this question: http://stackoverflow.com/questions/1743683/distinguishing-development-mode-and-release-mode-environment-settings-on-android Otherwise I do not know how you would do what you would want to do on Android. – Robert Massaioli May 17 '11 at 12:32

you able get the value from .properties file the example's below:

    Properties prop = new Properties();
    String propertiesPath = this.getFilesDir().getPath().toString() + "/app.properties";

    try {

        File existFile = new File(propertiesPath);

        if(existFile.isFile())
        {
            FileInputStream inputStream = new FileInputStream(propertiesPath);
            prop.load(inputStream);
            inputStream.close();    
        }   

    } catch (IOException e) {
        System.err.println("Failed to open app.properties file");
        e.printStackTrace();
    }
