I am having a bitmap in my Activity and I tried to convert this into a String like below

Bitmap bitmap = getIntent().getParcelableExtra("data");

  strpostimageurl=   BitMapToString(bitmap) ;

//method to convert bitmap to String

  public String BitMapToString(Bitmap bitmap){
     ByteArrayOutputStream baos=new  ByteArrayOutputStream();
     bitmap.compress(Bitmap.CompressFormat.PNG,100, baos);
     byte [] b=baos.toByteArray();
     String temp=Base64.encodeToString(b, Base64.DEFAULT);
     return temp;

}

And I am sending this String to Facebook Graph api Like below

String res=  

UrltoValue.getValuefromUrl("https://graph.facebook.com/"+Login.facebookid+"/feed?access_token="+accesstoken+"&method="+"post"+"&message="+"hi"+"&picture="+strpostimageurl);

But I am getting illegal Character response

I want to use Graph api because I have to post on wall of multiple friends – user1871951 Dec 06 '12 at 09:46
you can only share image with image url by graph api. Graph api will not support to Base64 string images. – Pratik Sharma Dec 06 '12 at 09:49
Can I convert Bitmap to image url – user1871951 Dec 06 '12 at 09:50
you can upload that bitmap to some server and get image url from your server. – Pratik Sharma Dec 06 '12 at 09:54
You can use service like Amazon s3 to upload images and get live url for your image. – Pratik Sharma Dec 06 '12 at 09:55
Is there any other option for me – user1871951 Dec 06 '12 at 10:02
with graph api most probably no. – Pratik Sharma Dec 06 '12 at 10:07
can I use Sdcard path to send as a url – user1871951 Dec 06 '12 at 10:12
local urls are not allowed with Graph Api. try with facebook sdk it will solve your problem. – Pratik Sharma Dec 06 '12 at 10:16
As I said in my previous post,I need to send the post to multiple friends by using their facebookids – user1871951 Dec 06 '12 at 10:29
you can do that by use of friend id with facebook sdk. You can loop through your friend list and access each of friend id to post picture on his/her wall. – Pratik Sharma Dec 06 '12 at 10:36
I really have no idea on facebook sdk,can you please provide me some code to do this – user1871951 Dec 06 '12 at 10:44
