Question

I created one app for database which contains a student table and 3 fields in it, but I don’t know how to add the file in the app to the sqlite database.

database helper:

  public class DatabaseHelper extends SQLiteOpenHelper {

  public static final String DATA_BASE="Mydatabase.db";
public static final String TABLE_NAME="Student";
public static final int DATABASE_VERSION =1;

public DatabaseHelper(Context context) {
 super(context, DATA_BASE, null, DATABASE_VERSION);
}

@Override
public void onCreate(SQLiteDatabase db) {

db.execSQL("CREATE TABLE " + TABLE_NAME + 
 "(Name TEXT, AGE NUMERIC, ADDRESS TEXT)"); }

@Override
public void onUpgrade(SQLiteDatabase db,
        int oldVersion, int newVersion) {

}
}

main activity:

public class DatabaseHelper extends SQLiteOpenHelper {

public static final String DATA_BASE="Mydatabase.db";
public static final String TABLE_NAME="Student";
public static final int DATABASE_VERSION =1;

public DatabaseHelper(Context context) {
 super(context, DATA_BASE, null, DATABASE_VERSION);
}

@Override
public void onCreate(SQLiteDatabase db) {

db.execSQL("CREATE TABLE " + TABLE_NAME + 
 "(Name TEXT, AGE NUMERIC, ADDRESS TEXT)"); }

@Override
public void onUpgrade(SQLiteDatabase db,
        int oldVersion, int newVersion) {

}
}

display activity:

  public class DisplayActivity extends Activity {

private ArrayList<String> arrayList = 
                    new ArrayList<String>();

private SQLiteDatabase Mydatabase;
ListView listView;
EditText enter;
@Override
public void onCreate(Bundle b) {
    super.onCreate(b);
    setContentView(R.layout.display);
    listView=(ListView)findViewById(R.id.listView);

    //OpenAndQueryDatabase

    try {
    DatabaseHelper db = new DatabaseHelper(this);
        //Open the database
        Mydatabase = db.getWritableDatabase();
        Cursor c = Mydatabase.rawQuery(
                "SELECT * FROM Student", null);

        if (c != null ) {
            if  (c.moveToFirst()) {
                do {
                    String Name = c.getString(
                            c.getColumnIndex("Name"));
                    int age = c.getInt(
                            c.getColumnIndex("AGE"));
                    String address = c.getString(
                            c.getColumnIndex("ADDRESS"));
                arrayList.add("Name    : " + Name +"\n"+ 
                               "Age        : " +age +"\n"+
                               "Address : " + address+"\n");
                }while (c.moveToNext());
            } 
        }           
        } catch (SQLiteException se ) { } 
        finally {
        if (Mydatabase != null) 
            Mydatabase.close();
    }


    //displayResultList

  listView.setAdapter(new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_1, 
                                    arrayList));
}
}

You can find your answer here. Just create a file inside a place in SD Card.

data/ folder is protected by the OS, just rooted devices can see it.

What you need is inside the answer of the link: open the file inside your SDCARD with new File(“/sdcard/myFolder/myFile.sqlite”).

File databaseLocation = new File("/sdcard/myFolder/myFile.sqlite" ); 
SQLiteDatabase db = SQLiteDatabase.openOrCreateDatabase(databaseLocation , null);
