Android - Copy files from assets to /data/data folder

Question

I need to use some files in my app. They are kept in asset folder. I saw discussions on SO, where the files are being copied from asset folder, to /data/data/<package_name> on the internal storage, and then being used. I get the code, but what I do not get is, what is the need to copy the assets to internal storage?

Answer 1

public final String path = "/data/data/com.aliserver.shop/databases/";
public final String Name = "store_db";

public void _copydatabase() throws IOException {

        OutputStream myOutput = new FileOutputStream(path + Name);
        byte[] buffer = new byte[1024];
        int length;
        InputStream myInput = MyContext.getAssets().open("store_db");
        while ((length = myInput.read(buffer)) > 0) {
            myOutput.write(buffer, 0, length);
        }
        myInput.close();
        myOutput.flush();
        myOutput.close();

    }
