Is it possible to create and remove . properties files from Android by the application itself?

Question

It is possible to create and remove files .properties of Android, by the application itself? Ex: after creating an annotation it creates a file .properties with the name of that note!

Answer 1

Cannot create files from the application. You can however interact with an existing file. To this end you should:

1. Create in your project, at the desired location the file you will use from the application.

2. After the created file, you can use a function like the one shown below to store data in it:

   public void CreatePropertiesFile(Context context) {
   
     Properties prop = new Properties();
     String propertiesPath = context.getFilesDir().getPath().toString() + "/app.properties";
   
     try {
       FileOutputStream out = new FileOutputStream(propertiesPath);
       prop.setProperty("HomeVersion", "0");
       prop.setProperty("DatePlaySquare", "0");
       prop.setProperty("CustomerID", "0");
       prop.setProperty("DeviceToken", "0");
       prop.setProperty("CurrentVersionMobile", "0");
       prop.setProperty("Domain", "Megazy");
       prop.setProperty("DownloadNewVersion","0");
       prop.store(out, null);
       out.close();
     } catch (IOException e) {
       System.err.println("Failed to open app.properties file");
       e.printStackTrace();
     }
   }
   

   You must adapt the function to your needs, but you already have an idea of how you can perform the operation.

On Android, when we talk about saving data, we almost always talk about Data Storage more specifically Shared Preferences. There is a very good tutorial on this subject:
