The official Facebook for Android SDK is open source, have a look http://github.com/facebook/facebook-android-sdk

I was having the same case and solved the problem by implementing a webview client and webchrome client as shown below. I have done a sample demonstrating the same how to upload photos on your android application. Try these code and it will definitely work for you. You can download a working demo from here

package com.whatsonline.androidphotouploadonfacebook;

import android.app.Activity;
import android.content.ActivityNotFoundException;
import android.content.Intent;
import android.content.res.Configuration;
import android.graphics.Bitmap;
import android.net.Uri;
import android.os.Bundle;
import android.view.ViewGroup;
import android.webkit.ValueCallback;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.LinearLayout;

public class upload extends Activity {

    WebView web;
    private ValueCallback<Uri> mUploadMessage;
    private final static int FILECHOOSER_RESULTCODE=1;
    LinearLayout ln1;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.upload);

        web = new WebView(this);
        web.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.FILL_PARENT));

        ln1=(LinearLayout) findViewById(R.id.ln1);

        WebSettings settings=web.getSettings();
        settings.setJavaScriptEnabled(true);


        web.loadUrl("http://www.facebook.com");
        web.setWebViewClient(new myWebClient());

        web.setWebChromeClient(new WebChromeClient() {
            //The undocumented magic method override
            //Eclipse will swear at you if you try to put @Override here
            // For Android 3.0+
            public void openFileChooser(ValueCallback<Uri> uploadMsg) {

                mUploadMessage = uploadMsg;
                Intent i = new Intent(Intent.ACTION_GET_CONTENT);
                i.addCategory(Intent.CATEGORY_OPENABLE);
                i.setType("image/*");
                upload.this.startActivityForResult(Intent.createChooser(i, "File Chooser"), FILECHOOSER_RESULTCODE);

            }

            // For Android 3.0+
            public void openFileChooser(ValueCallback uploadMsg, String acceptType) {
                mUploadMessage = uploadMsg;
                Intent i = new Intent(Intent.ACTION_GET_CONTENT);
                i.addCategory(Intent.CATEGORY_OPENABLE);
                i.setType("*/*");
                upload.this.startActivityForResult(
                        Intent.createChooser(i, "File Browser"),
                        FILECHOOSER_RESULTCODE);
            }

            //For Android 4.1
            public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType, String capture) {
                mUploadMessage = uploadMsg;
                Intent i = new Intent(Intent.ACTION_GET_CONTENT);
                i.addCategory(Intent.CATEGORY_OPENABLE);
                i.setType("image/*");
                upload.this.startActivityForResult(Intent.createChooser(i, "File Chooser"), upload.FILECHOOSER_RESULTCODE);

            }

          });
        ln1.addView(web);
    }
    public class myWebClient extends WebViewClient
    {
        @Override

        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);

        }

        @Override

        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
        }
    }

    //flipscreen not loading again
    @Override
    public void onConfigurationChanged(Configuration newConfig){
        super.onConfigurationChanged(newConfig);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent intent) {

        if(requestCode==FILECHOOSER_RESULTCODE){
            if (null == mUploadMessage) return;
            Uri result = intent == null || resultCode != RESULT_OK ? null : intent.getData();
            mUploadMessage.onReceiveValue(result);
            mUploadMessage = null;

        }
   }
    }

Besides, add the permissions for internet access, read from external storage and camera capture.
