Android Sqlite shows no such table

i want to add some image uri's to the Database. my Database table has two columns id and String Uri. The Problem is it shows No such table exist when trying to insert some Uris to Table. Here is my Code of Database Adapter Class.

package com.example.mystorage;

import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.SQLException;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;

public class DBAdapter {
// for customer registration
static final String KEY_ID = "id";
static final String KEY_URI = "uri";


static final String DATABASE_NAME = "IMAGE_DB";

static final String DATABASE_TABLE = "temp_images1";

static final int DATABASE_VERSION = 2;

static final String DATABASE_CREATE = "create table temp_images1 (id integer       autoincrement, "
        + "uri text not null);";

final Context context;
DatabaseHelper DBHelper;
SQLiteDatabase db;

public DBAdapter(Context ctx) {
    this.context = ctx;
    DBHelper = new DatabaseHelper(context);
}

private static class DatabaseHelper extends SQLiteOpenHelper {
    public DatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);

    }

    public void onCreate(SQLiteDatabase db) {
        try {
            db.execSQL(DATABASE_CREATE);
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }

    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion)     {
        db.execSQL("DROP TABLE IF EXISTS temp_images1");
        onCreate(db);
    }

}

public DBAdapter open() throws SQLException {
    db = DBHelper.getWritableDatabase();
    return this;
}

public void close() {
    DBHelper.close();
}



// //////////////////////////////////////for
// customerRegistration////////////////
// customer registration for retrieve data
public Cursor getAllImages() {
    return db.query(DATABASE_TABLE, new String[] {KEY_URI}, null,
            null, null, null, null);
}
public Cursor getContentimage(long id) throws SQLException {
    Cursor c = db.query(true, DATABASE_TABLE,
            new String[] { KEY_ID, KEY_URI },
            KEY_ID + "=" + id, null, null,
            null, null, null);
    if (c != null) {
        c.moveToFirst();
    }
    return c;
}
// customer registration for update data
public boolean updateimages(long id, String uri) {
    ContentValues args = new ContentValues();
    // args.put(KEY_ID,id);
    args.put(KEY_URI, uri);
    return db.update(DATABASE_TABLE, args, KEY_ID + "=" + id, null) > 0;
}

// customer registration for insert data
public long insertImages(String uri) {
    ContentValues args = new ContentValues();
    //args.put(KEY_ID, id);
    args.put(KEY_URI, uri);
    long n = db.insert(DATABASE_TABLE, null, args);
    //db.insertOrThrow(DATABASE_TABLE, null, args);
    return n;
}

// customer registration for remove data
public boolean deleteImages(long id) {
    return db.delete(DATABASE_TABLE, KEY_ID + "=" + id, null) > 0;

}
}

here is My ImageAdapter class where i am calling the insert method. mThumbs is uri Arraylist to Store the Content of Database While Retrieving.

public ImageAdapter(Context c, android.net.Uri uri) {
    mContext = c;
    db= new DBAdapter(mContext);
    try {
    db.open();
    db.insertImages(uri.toString());
    db.close();
    }catch(Exception e){
        e.printStackTrace();
    }
    upadteAllImages();

       notifyDataSetChanged();
}

public ImageAdapter(Context c, ArrayList<Uri> imageUris) {
    mContext = c;
    db= new DBAdapter(mContext);
    try {
    db.open();
    for (int i = 0; i < imageUris.size(); i++){
    db.insertImages(imageUris.get(i).toString());
    }
    db.close();
    }catch(Exception e){
        e.printStackTrace();
    }
    upadteAllImages();

       notifyDataSetChanged();
}

private void upadteAllImages() {
    mTHumbs.clear();

    try{
        db.open();
        Cursor c = db.getAllImages();
        if (c.moveToFirst()) {
            while (c.moveToNext()){
                String uri = c.getString(1);
                mTHumbs.add(Uri.parse(uri));
            }
        }
        //mTHumbs.add((Uri) db.getAllImages());

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