Answer 1

Please use below code for store images into sqlite database, it will solve your problem.

MySQLActivity.java:-

public class MySQLActivity extends Activity implements OnClickListener
{
    protected static TextView textView;
    protected static ImageView bmImage;
    protected Button start;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        bmImage = (ImageView)findViewById(R.id.imageView1);
        textView = (TextView) findViewById(R.id.textView1);

        start = (Button) findViewById(R.id.button1);
        start.setOnClickListener(this); 

        DownloadFile();
    }

    public void onClick(View v) 
    {
        SQLiteDatabase myDb;       
        String MySQL;
        int icount;
        byte[] byteImage1 = null;
        byte[] byteImage2 = null;
        MySQL="create table emp1(_id INTEGER primary key autoincrement, fio TEXT not null, picture BLOB);";
        myDb = openOrCreateDatabase("/sdcard/Nick/MyWeatherDB.db", Context.MODE_PRIVATE, null);

        String s=myDb.getPath();
        textView.append("\r\n" + s+"\r\n");       
        myDb.execSQL("delete from emp1");
        ContentValues newValues = new ContentValues();
        newValues.put("fio", "Иванов Петр Сергеевич");

        /////////// insert picture to blob field ///////////////////// 
        try
        {
            FileInputStream instream = new FileInputStream("/sdcard/Dipak/Keshariya.png"); 
            BufferedInputStream bif = new BufferedInputStream(instream); 
            byteImage1 = new byte[bif.available()]; 
            bif.read(byteImage1); 
            textView.append("\r\n" + byteImage1.length+"\r\n"); 
            newValues.put("picture", byteImage1); 

            long ret = myDb.insert("emp1", null, newValues); 
            if(ret<0) textView.append("\r\n!!! Error add blob filed!!!\r\n");
        } catch (IOException e) {
            textView.append("\r\n!!! Error: " + e+"!!!\r\n");   
        }

        ////////////Read data ////////////////////////////  
        Cursor cur = myDb.query("emp1",null, null, null, null, null, null);
        cur.moveToFirst();
        while (cur.isAfterLast() == false)
        {
            textView.append("\r\n" + cur.getString(1)+"\r\n");
            cur.moveToNext();
        }

        ///////Read data from blob field////////////////////
        cur.moveToFirst();
        byteImage2=cur.getBlob(cur.getColumnIndex("picture"));
        bmImage.setImageBitmap(BitmapFactory.decodeByteArray(byteImage2, 0, byteImage2.length));
        textView.append("\r\n" + byteImage2.length+"\r\n"); 

        //////////////////////////    
        cur.close();
        myDb.close();
  }

  public void DownloadFile() 
  {   
      Bitmap bitmap1 = null;                    
      bitmap1 = BitmapFactory.decodeFile("/sdcard/Dipak/Dipak.jpg"); //weather.png");
      bmImage.setImageBitmap(bitmap1);
  }
}

Answer 2

i would suggest to avoid saving images to database , not only on android .

this makes sense since it will slow down anything that is related to the database . also , the cursor won't be able to cache the results in order to move between the rows of the tables.

instead , put a filename to point to a path on your app's storage . you could also add where it's stored (internal/external storage) .

Answer 3

First make field in sqlite as blob datatype

than get byte and store in databse image.getBytes();

or if you have bitmap than convert into byte array

and store into database

 public static byte[] getBitmapAsByteArray(Bitmap bitmap, boolean type) {
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
    if (type) {
        bitmap.compress(CompressFormat.PNG, 0, outputStream);
    } else {
        bitmap.compress(CompressFormat.JPEG, 0, outputStream);
    }
    return outputStream.toByteArray();
}
