I would like to know if it's possible and if so how I can transmit the the raw image data instead of specifying the URL to an image on the web when posting to my Facebook wall?
The working code I currently have results in this:
http://1.bp.blogspot.com/-klSLFEmvHy0/TxpPMIay0xI/AAAAAAAAAKQ/iLZv-QtmThc/s1600/fbpost.JPG (sorry I don't have enough credits to embed pictures so open the URL please :-)
Which is moreorless what I want with the caption, title, links etc. but my ultimate objective is to make the heart-shaped image displayed above be the outputted one that my app generates each time a user decides to post their results to Facebook (the contents are dynamically generated on the image). I don't want to implement uploading some third party server and then sharing that URL.
I've seen around people referring to code like this:
...
byte[] data = null;
Bitmap bi = BitmapFactory.decodeFile(imagePath);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bi.compress(Bitmap.CompressFormat.JPEG, 100, baos);
data = baos.toByteArray();
params.putByteArray(...
but that seems to be for uploading photos directly to an album which isn't what I want either.
My working code so far is:
private void loginAndPostToFacebook() {
mFacebook = new Facebook(FACEBOOK_APP_ID);
mFacebook.authorize(this, new String[] { "publish_stream" }, new DialogListener() {
@Override
public void onComplete(Bundle values) {
postOnWall();
}
@Override
public void onFacebookError(FacebookError error) {
L.t(getString(R.string.error_facebook_error) + ": " + error.getMessage());
}
@Override
public void onError(DialogError e) {
L.t(getString(R.string.error_facebook_error) + ": " + e.getMessage());
}
@Override
public void onCancel() {
}
});
}
public void postOnWall() {
Bundle params = new Bundle();
// Message
params.putString("message", "my msg");
// Name
params.putString("name", "app name");
// Caption
params.putString("caption", "caption");
// Description
params.putString("description", "description");
// Here's where I'd insert my dynamically generated image data...
params.putString("picture", "http://4.bp.blogspot.com/-VaNzm3xMOtk/TxpKzhxpdEI/AAAAAAAAAKI/08Kc5b4HW0Q/s1600/sexometer128x128neutral_icon.png");
// Link
params.putString("link", "http://www.stackoverflow.com");
try {
String response = mFacebook.request("me");
response = mFacebook.request("me/feed", params, "POST");
if (response == null || response.equals("") || response.equals("false")) {
L.t(getString(R.string.error_facebook_error) + ": blank response");
return;
} else if (response.toLowerCase().contains("error")) {
L.t(getString(R.string.error_facebook_error) + ": " + response);
return;
}
} catch(Exception e) {
L.t(getString(R.string.error_facebook_error) + ": " + e.getMessage());
return;
}
L.t(getString(R.string.success_posted_to_facebook));
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (mFacebook != null) {
mFacebook.authorizeCallback(requestCode, resultCode, data);
}
}
