if you want import your database file from asset folder than below code can help you

void checkDB() throws Exception {
        try {
            SQLiteDatabase dbe = SQLiteDatabase
                    .openDatabase(
                            "/data/data/com.yourpackagename/databases/yourfile.sqlite",
                            null, 0);
            Log.d("opendb", "EXIST");
            dbe.close();
        } catch (Exception e) {

            AssetManager am = getApplicationContext().getAssets();
            OutputStream os = new FileOutputStream(
                    "/data/data/com.yourpackagename/databases/yourfile.sqlite");
            byte[] b = new byte[100];

            int r;
            InputStream is = am.open("yourfile.sqlite");
            while ((r = is.read(b)) != -1) {
                os.write(b, 0, r);
            }
            Log.i("DATABASE_HELPER", "Copying the database ");
            is.close();
            os.close();
        }
