ImageView img1;
    img1 = (ImageView) findViewById (R.id.img1);

        URL newurl = new URL("http://10.0.2.2:80/Gallardo/Practice/files/images/donut.jpg");
        Bitmap mIcon_val = BitmapFactory.decodeStream(newurl.openConnection() .getInputStream());
        img1.setImageBitmap(mIcon_val);

I get image from url but I want to store it to my drawable, how?

Everything in the apk will be read only. So you can't write to drawable.

you have to use "blob" to store image.

ex: to store a image in to db

public void insertImg(int id , Bitmap img ) {   


    byte[] data = getBitmapAsByteArray(img); // this is a function

    insertStatement_logo.bindLong(1, id);       
    insertStatement_logo.bindBlob(2, data);

    insertStatement_logo.executeInsert();
    insertStatement_logo.clearBindings() ;

}

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

to retrieve a image from db

public Bitmap getImage(int i){

    String qu = "select img  from table where feedid=" + i ;
    Cursor cur = db.rawQuery(qu, null);

    if (cur.moveToFirst()){
        byte[] imgByte = cur.getBlob(0);
        cur.close();
        return BitmapFactory.decodeByteArray(imgByte, 0, imgByte.length);
    }
    if (cur != null && !cur.isClosed()) {
        cur.close();
    }       

    return null ;
}

You can also check this saving image to database

You can construct Drawable by using this constructor:

Drawable drawable = new BitmapDrawable(getResources(), mIcon_val);

You can set it to the ImageView like so: 

img1.setImageDrawable(drawable);

Its not possible to place image in drawable folder while running the apk.. Saving an image to SDcard is possible..
