I've looked all over the internet and can't seem to find what i'm looking for...

I'm just trying to find a site with some examples on how to use the OFFICIAL facebook android SDK http://github.com/facebook/facebook-android-sdk

To be specific i'd like to see some examples on notification use and simple photo upload. But i'll take anything to help get a feel for using the SDK.

If anyone knows of any examples please share thank you so much!

I asked a similar question a few weeks ago regarding the official Facebook Android SDK and posting content to one's wall (Android/Java -- Post simple text to Facebook wall?). That should help you get a feel for what it's like to post text to one's wall. I should point out though that you need to first create a Fackbook app and apply for an API key from Fackbook.com (https://kunukd.com/)...if it asks about the platform of the app you intent to create, choose mobile.

You can modify the code in the Stack Overflow link I posted (above) to post photos too. At present though, according to the official git page for the Facebook Android SDK (under "Known Issues"):

3.Binary API parameters (such as uploading pictures) is not yet supported -- coming soon...

So, while you can post a photo to your wall if you have the URL of the image file (the file must already be on the Internet), you can't use this SDK to send binary/byte data of the photo from the Android device (yet... as of 07/24/10). At least, that's what I gather from the statement above.

Replace the following lines of the sample code I posted in the other Stack Overflow post (link above):

Bundle parameters = new Bundle();
parameters.putString("message", "this is a test");// the message to post to the wall
facebookClient.dialog(this, "stream.publish", parameters, this);// "stream.publish" is an API call

with this

Bundle parameters = new Bundle();
parameters.putString("message", "Test Photo");
parameters.putString("attachment", "{\"name\":\"My Test Image\","
+"\"href\":\""+"http://www.google.com"+"\","
+"\"media\":[{\"type\":\"image\",\"src\":\""+"http://www.google.com/logos/mucha10-hp.jpg"+"\",\"href\":\""+"http://www.google.com"+"\"}]"
+"}");
facebookClient.dialog(this, "stream.publish", parameters, this);

and you should be able to post photos to your wall (as well as text and links).

For more help on structuring the "attachment" string, go here: http://www.mobisoftinfotech.com/blog/android/845/.

Other than that, consider using a third-party package or wait for the official SDK to be updated if you need to post photos to an album directly from the device.

You can do it this way:

byte[] data = null;
try {
    ContentResolver cr = mainActivity.getContentResolver();
    InputStream fis = cr.openInputStream(localSnapshotUri);
    Bitmap bi = BitmapFactory.decodeStream(fis);
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    bi.compress(Bitmap.CompressFormat.JPEG, 100, baos);
    data = baos.toByteArray();              
} catch (FileNotFoundException e) {
    e.printStackTrace();
}     

Bundle params = new Bundle(); 
params.putString("method", "photos.upload");          
params.putByteArray("picture", data);

AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
mAsyncRunner.request(null, params, "POST", new SampleUploadListener());

Parameters used here are:

• localSnapshotUri which points to some image in you /sdcard/.. or wherever it is :)
• mainActivity that is app main activity
• SampleUploadListener an implemetation of AsyncFacebookRunner.RequestListener interface

Have a nice programming!

Just posted here the simple way to upload a photo:

android facebook publish photo

Code:

byte[] data = null;

Bitmap bi = BitmapFactory.decodeFile(photoToPost);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bi.compress(Bitmap.CompressFormat.JPEG, 100, baos);
data = baos.toByteArray();

Bundle params = new Bundle();
params.putString("method", "photos.upload");
params.putByteArray("picture", data);

AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
mAsyncRunner.request(null, params, "POST", new SampleUploadListener(), null);

By far the easiest and working example of posting to user's wall without the dialog once logged on, and using the new Facebook SDK, is: http://www.integratingstuff.com/2010/10/14/integrating-facebook-into-an-android-application/

By the way, posting images is done with:

parameters.putString("picture", "http://www.google.com/logos/mucha10-hp.jpg");
