Hello,
I asked a similar question a few weeks ago regarding the official Facebook Android SDK and posting content to one's wall (http://stackoverflow.com/questions/2953146/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 (http://www.shoutmeloud.com/how-to-acquire-your-facebook-api-key.html)...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.
I hope that helps.
