I am creating an app and use Ratio.xml as database. I added this file manually in external storage in a folder and my app is working.

I want to include this file in my apk package and install this file in any of the folder in the device and not in external storage . I added this file in asset folder but it is read only, I can't modify and save in this file. Please tell me where to put this file in my project and create package.

I would keep the "original" version of your Ratio.xml in the asset folder, and on start-up of the app I would copy it to the Internal Storage by reading the contents of Ratio.xml and writing it to a new file using Context.openFileOutput. Obviously only overwrite the copy if it's not already there.

Calling Context.openFileOutput will return a FileOutputStream so using that it's pretty much standard Java to read and write the file. The file will be private to you application. I think using the Internal Storage[^] is the best solution here, but there are other ways[^] for you to achieve the same, but in different ways.

Hope this helps,

Store is as an Asset in the project.
And I don't think it cab be added as a writable file to the storage during setup, that's something you'd have to implement yourself and have your application do on startup.
See[^], it's for an SQLite database, but the principle is the same.
