java.io.FileNotFoundException: open failed: ENOENT (No such file or directory

J'ai cr¨¦e une base de donn¨¦es SQLite qui contient deux tableaux :tableaux pour les cat¨¦gories et tableaux pour les images qui contient les adress
//tableau category
private static final String CREATE_BD_CATEGORY="CREATE TABLE "
+ TABLE_CATEGORY + " (" +
COL_ID_CATEGORY + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
COL_CATEGORY_NAME + " TEXT NOT NULL, " +
COL_IMAGE_CATEGORY + " TEXT," +
" FOREIGN KEY ("+COL_IMAGE_CATEGORY+") REFERENCES "+ TABLE_IMAGE +" ("+COL_ID_IMAGE +")); " ;
//tableau image
private static final String CREATE_BD_IMAGE="CREATE TABLE "
+ TABLE_IMAGE + " (" +
COL_ID_IMAGE + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
COL_ADRESS_IMAGE + " TEXT NOT NULL ); " ;
Je veux charger les images stock¨¦s dans la base et l'utilis¨¦ dans un bouton,
donc j'ai cr¨¦e une m¨¦thode pour r¨¦cup¨¦rer l'@ de l'image, mais lorsque je compile, l'emulateur affihe des boutons mais sans image
voici la m¨¦thode :
public String getImage(int id)//afficher une image
{
database = DBHelper.getReadableDatabase(); // open database to perform some operation

Cursor c = database.rawQuery("SELECT " + COL_ADRESS_IMAGE + " FROM "
+ TABLE_IMAGE + " WHERE " + COL_ID_IMAGE +" IN (SELECT " + COL_IMAGE_CATEGORY + " FROM "
+ TABLE_CATEGORY + " WHERE " + COL_ID_CATEGORY + "= '" + id + "')",null );

if(c.moveToFirst())
{ //Edited based on suggestion from SAM
String strCatName = c.getString(c.getColumnIndex(COL_ADRESS_IMAGE ));
c.close();
database.close();
return strCatName;
}
else
{
return "";
}

et au niveau de main activity :
ImageButton b1= new ImageButton(this);
image = db.getImage(i);
b1.setImageURI(Uri.parse(image));

le logcat affiche comme r¨¦sultat :

Be sure to describe which is line 56 of the code, and which values you're passing to any methods in it - that seems to be (at least part of) the problem.

I created a SQLite database which contains two tables: tables for classes and tables for images that contain the adress of image
I want to load images stored in the database and used in a button, i just want to know how can i do it here's the code :
public void putLinearLayout(double number)
{
LinearLayout Linear = (LinearLayout)findViewById(R.id.linearlayout2);
DataBase db = new DataBase(this);
String name;
String image = null;
int mButtonHeight = 70;//hauteur
int mButtonWidth = 120;//longueur
Button im = (Button)findViewById(R.id.button4);
Drawable d = Drawable.createFromPath("res/drawable/pizza.jpg");
im.setBackground(d);

for(int i=1;i<=number;i++)
{
LinearLayout L = new LinearLayout(this);//line 56
//L.setBackgroundColor(Color.WHITE);
LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT); //<--this line , is what you were missing
L.setLayoutParams(params); //<-- and then this

ImageButton b1= new ImageButton(this);
image = db.getImage(i);
b1.setImageURI(Uri.parse(image));
TextView tv = new TextView(this);
tv.setGravity(Gravity.CENTER);
tv.setTextColor(Color.BLUE);
name=db.getCategoryName(i);
tv.setText(name);
L.setOrientation(LinearLayout.VERTICAL);
b1.setMinimumWidth(mButtonWidth);
b1.setMinimumHeight(mButtonHeight);
L.addView(b1);
L.addView(tv);
Linear .addView(L);
}
