Download SQLite file programmatically

rav :

In my android application i'm using SQLite database. And I need to have an option in the app to download the database file.

Because sometimes I need to view the data there , so the user will download the file and send it to me and i will browse it using SQLite browsers.

Is the doable? if yes how?

   String src = "/data/data/myPackage/databases/Mydb.db";
   String dest = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS).getPath();

copyFileOrDirectory(src , dest);

 public static void copyFileOrDirectory(String srcDir, String dstDir) {

        try {
            File src = new File(srcDir);
            File dst = new File(dstDir, src.getName());

                copyFile(src, dst);

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static void copyFile(File sourceFile, File destFile) throws IOException {
        if (!destFile.getParentFile().exists())
            destFile.getParentFile().mkdirs();

        if (!destFile.exists()) {
            destFile.createNewFile();
        }

        FileChannel source = null;
        FileChannel destination = null;

        try {
            source = new FileInputStream(sourceFile).getChannel();
            destination = new FileOutputStream(destFile).getChannel();
            destination.transferFrom(source, 0, source.size());
        } finally {
            if (source != null) {
                source.close();
            }
            if (destination != null) {
                destination.close();
            }
        }
    }

Nizar :

Usually, the SQLite database is available in the /data/data/your.applications.package/databases/database.db path.

So, you could use that path; however, I suggest that you get the Database Path in the following way:

File dbFile = getDatabasePath("dbname");
String dbPath = dbFile.getPath();

Then, you can copy the database from this folder into the folder that you desire. Copying the database to the Downloads could simulate the "download" of the SQLite database.
