Answer 1

Here is a complete solution for you to use .properties file in your project.

1 Create a file named app.properties in assets folder of your android project

2 edit the file and write with in properties that you want to use for example as

test=success 

And Save file

3 Write this Method with in your Activity Class

  private Properties loadPropties() throws IOException {
  String[] fileList = { "app.properties" };
  Properties prop = new Properties();
  for (int i = fileList.length - 1; i >= 0; i--) {
     String file = fileList[i];
     try {
        InputStream fileStream = getAssets().open(file);
        prop.load(fileStream);
        fileStream.close();
     } catch (FileNotFoundException e) {
        Log.d(TAG, "Ignoring missing property file " + file);
     }
  }
  return prop;
  }

4 With in OnCreate Method write some thing like this

     Properties prop = null; 
     try {
        prop = loadPropties();
     } catch (IOException e) {
        Log.e(TAG, "Exception", e);
     }
     Toast.makeText(getApplicationContext(), "Result " + prop.getProperty("test"),
                    Toast.LENGTH_LONG).show();

5 add necessary imports

Hope this helps :)

Read about Data Storage in Android and more specifically Shared Preferences. For more complete usage of saving user preferences, read about the PreferenceActivity.
