I ahve added the following code bUt an error on insert ie insert is undefined

 Bitmap photo = ((BitmapDrawable)v.getDrawable()).getBitmap();
    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    photo.compress(Bitmap.CompressFormat.PNG, 100, bos);
    byte[] bArray = bos.toByteArray();
    Databasehandler db =new Databasehandler(this);    
    ContentValues values = new ContentValues();         
    values.put("image", bArray);            
    db.insert("image" , null, values);

Answer 1

Get bitmap of the image view using:

Bitmap photo = ((BitmapDrawable)image.getDrawable()).getBitmap();

Create byte array of the bitmap:

ByteArrayOutputStream bos = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.PNG, 100, bos);
byte[] bArray = bos.toByteArray();

Then you can save data in table using following way.

db = YourDBHelper.getInstance(ctx).getWritableDatabase();    
ContentValues values = new ContentValues();         
values.put("image", bArray);            
db.insert(TABLE_NAME , null, values);

Answer 2

SQLITE data base cannot be used to store Image files directly. However the options you have are following:

1. Save the image that you received to SD card. May be create a separate folder in which you will store all the images. Then Create a column imagePath in your table structure and save the path of the image to this column.

   Rendering: Here you will fetch the corresponding path from the DB, check if the file Exists at that path(might have been deleted by the user), and if found, get Stream from the file write it to a bitmap and associate it to the required container.

2. Convert the bitmap received to a BASE64 String. Store this as String to the Data Base.

   Rendering: Here you will have to convert the BASE64 back to Bitmap and associate it to the required container.

Answer 3

Save it on sdcard and path of sdcard on sqlite database

   Bitmap bitmap = ((BitmapDrawable)image.getDrawable()).getBitmap();
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap2.compress(Bitmap.CompressFormat.JPEG, 100,stream);
    File file = new File(path);
    FileOutputStream fOut = new FileOutputStream(file);

    bitmap2.compress(Bitmap.CompressFormat.JPEG, 100, fOut);
    fOut.flush();
    fOut.close();
