How to chunk the file.</p> <p>I tried like this way: </p> <pre><code>private static String DB_PATH = "/data/data/com.android.xont.controller/databases/"; private static String DB_NAME = ""; private SQLiteDatabase ventura; private final Context myContext; // private SQLiteDatabase myDataBase=null; private DataBaseHelper myDbHelper; public DataBaseHelper(Context context, String DB_NAME) { super(context, DB_NAME, null, 1); this.myContext = context; this.DB_NAME = DB_NAME; } /** * Creates a empty database on the system and rewrites it with your own * database. **/ public void createDataBase() throws IOException { boolean dbExist = checkDataBase(); File Path = myContext.getDir("Data", 0); File DBFile = new File(Path, "DEMOUserVentura_HEMA.db"); if (dbExist) { } else { this.getReadableDatabase().close(); //this.getReadableDatabase().getPath(); //System.out.println( " ===== " + this.getReadableDatabase().getPath()); try { copyDataBase(); } catch (IOException e) { throw new Error(e); } } } private boolean checkDataBase() { SQLiteDatabase checkDB = null; try { String myPath = DB_PATH + DB_NAME; checkDB = SQLiteDatabase.openDatabase(myPath, null,SQLiteDatabase.OPEN_READONLY); } catch (SQLiteException e) { // database does't exist yet. } if (checkDB != null) { checkDB.close(); } return checkDB != null ? true : false; } private void copyDataBase() throws IOException { //AssetManager am = myContext.getAssets(); //String outFileName = DB_PATH + DB_NAME; // OutputStream os = new FileOutputStream(outFileName); //outFileName.createNewFile(); // byte []b = new byte[1024]; //int i, r; //String []Files = am.list(""); // Arrays.sort(Files); //for(i=1;i&lt;10;i++) //{ // String fn = String.format("%d.db", i); //if(Arrays.binarySearch(Files, fn) &lt; 0) // break; //InputStream is = am.open(fn); // while((r = is.read(b)) != -1) //os.write(b, 0, r); //is.close(); // } // os.close(); // Open your local db as the input stream InputStream myInput = myContext.getAssets().open(DB_NAME); // Path to the just created empty db String outFileName = DB_PATH + DB_NAME; // Open the empty db as the output stream OutputStream myOutput = new FileOutputStream(outFileName); // transfer bytes from the inputfile to the outputfile byte[] buffer = new byte[1024]; int length; while ((length = myInput.read(buffer)) &gt; 0) { myOutput.write(buffer, 0, length); } // Close the streams myOutput.flush(); myOutput.close(); myInput.close(); } public void openDataBase() throws SQLException { // Open the database String myPath = DB_PATH + DB_NAME; ventura = SQLiteDatabase.openDatabase(myPath, null, SQLiteDatabase.OPEN_READONLY); } @Override public synchronized void close() { if (ventura != null) ventura.close(); super.close(); } </code></pre> <p>Please provide some solution to this.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
