您好，首先下载 Facebook SDK..

Facebook SDK

然后在Oncreate方法中

//用于认证

public class FacebollAppforPhotoUpload extends Activity {

 //------------------FB-------------------------


Facebook facebook = new Facebook("APP_KEY");
String permissions[] = {""};
 String statusString = "";

 //---------------------------------------------


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
    WindowManager.LayoutParams.FLAG_FULLSCREEN);




    statusString="testing Post For Application Development";


    setContentView(R.layout.main);

     facebook.authorize(this, permissions, new DialogListener() {
        @Override
        public void onComplete(Bundle values) {


        //  updateStatus(values.getString(Facebook.TOKEN));
            uploadphoto(values.getString(Facebook.TOKEN));

            finish();

        }


        @Override
        public void onFacebookError(FacebookError error) {}

        @Override
        public void onError(DialogError e) {}

        @Override
        public void onCancel() {

            finish();

        }
    });

图片上传方式

public void uploadphoto(String accessToken)
{
    byte[] data = null;

    ContentResolver cr = FacebollAppforPhotoUpload.this.getContentResolver();
   // InputStream fis = cr.openInputStream(localSnapshotUri);
    Bitmap bi = BitmapFactory.decodeResource(getResources(), R.drawable.icon);
    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 RequestListener(){

        @Override
        public void onComplete(String response, Object state) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onIOException(IOException e, Object state) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onFileNotFoundException(FileNotFoundException e,
                Object state) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onMalformedURLException(MalformedURLException e,
                Object state) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onFacebookError(FacebookError e, Object state) {
            // TODO Auto-generated method stub

        }},null);
}
