Question

I'm new to Android. I'm searching for load photo to facebook by authorization, getting access_token. How to do this? Please give me a sample code in Java.

Answer 1

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);

facebook.authorize(FbdemoActivity.this, new String[]{ "user_photos,publish_checkins,publish_actions,publish_stream"},new DialogListener() {
                    @Override
                    public void onComplete(Bundle values) {



                    }

                    @Override
                    public void onFacebookError(FacebookError error) {
                    }

                    @Override
                    public void onError(DialogError e) {
                    }

                    @Override
                    public void onCancel() {
                    }
                });


public void postImageonWall() {

           byte[] data = null;

             Bitmap bi = BitmapFactory.decodeFile("/sdcard/viewitems.png");
             ByteArrayOutputStream baos = new ByteArrayOutputStream();
             bi.compress(Bitmap.CompressFormat.JPEG, 100, baos);
             data = baos.toByteArray();


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

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


    }


public class SampleUploadListener extends BaseRequestListener {

    public void onComplete(final String response, final Object state) {
        try {
            // process the response here: (executed in background thread)
            Log.d("Facebook-Example", "Response: " + response.toString());
            JSONObject json = Util.parseJson(response);
            final String src = json.getString("src");

            // then post the processed result back to the UI thread
            // if we do not do this, an runtime exception will be generated
            // e.g. "CalledFromWrongThreadException: Only the original
            // thread that created a view hierarchy can touch its views."

        } catch (JSONException e) {
            Log.w("Facebook-Example", "JSON Error in response");
        } catch (FacebookError e) {
            Log.w("Facebook-Example", "Facebook Error: " + e.getMessage());
        }
    }

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

    }
}

here is the whole code try it it will definately work for you and it is work for me also

The easiest way for you is to use the existing SDK, something like that:
http://github.com/facebook/facebook-android-sdk/
http://code.google.com/p/fbconnect-android/
http://wiki.developers.facebook.com/index.php/User:Android

The more flexible way is to implement the API yourself, here are the docs that will be useful:

If you want to publish a photo with a description you can do this :

public void publishPhoto(byte[] imgData, string message) {

AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner (facebook);

Bundle parameters = new Bundle ();
parameters.putString (Facebook.TOKEN, facebook.getAccessToken());
parameters.putString ("message", message);
parameters.putByteArray ("source", imgData);

mAsyncRunner.Request ("me/photos", parameters, "POST", new RequestListener (), null);
}

Successfully i have uploaded the photos on facebook wall I used the following code.

In your Main Activity do the following;

btn1.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            authenticatedFacebook.authorize(Facebooktest2Activity.this, new String[]{ "user_photos,publish_checkins,publish_actions,publish_stream"},new DialogListener() {
                    @Override
                    public void onComplete(Bundle values) {
                        postImage();
                        Toast.makeText(getApplicationContext(), "Image Posted on Facebook.", Toast.LENGTH_SHORT).show();


                    }

                    @Override
                    public void onFacebookError(FacebookError error) {
                    }

                    @Override
                    public void onError(DialogError e) {
                    }

                    @Override
                    public void onCancel() {
                    }

    });


        }
});






}

public void postImage(){
     byte[] data = null;               

        Bitmap bi = BitmapFactory.decodeFile("/sdcard/img.jpg");
        //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(Facebook.TOKEN, authenticatedFacebook.getAccessToken());              
        params.putString("method", "photos.upload");              
        params.putByteArray("picture", data);               
        AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(authenticatedFacebook);              
        mAsyncRunner.request(null, params, "POST", new SampleUploadListener(), null);   

}


public class SampleUploadListener extends BaseKeyListener implements RequestListener {

    public void onComplete(final String response, final Object state) {
        try {
            // process the response here: (executed in background thread)
            Log.d("Facebook-Example", "Response: " + response.toString());
            JSONObject json = Util.parseJson(response);
            final String src = json.getString("src");

            // then post the processed result back to the UI thread
            // if we do not do this, an runtime exception will be generated
            // e.g. "CalledFromWrongThreadException: Only the original
            // thread that created a view hierarchy can touch its views."

        } catch (JSONException e) {
            Log.w("Facebook-Example", "JSON Error in response");
        } catch (FacebookError e) {
            Log.w("Facebook-Example", "Facebook Error: " + e.getMessage());
        }
    }

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

    }

    public Bitmap getInputType(Bitmap img) {
        // TODO Auto-generated method stub
        return img;
    }

    @Override
    public int getInputType() {
        // TODO Auto-generated method stub
        return 0;
    }

    @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

    }
}

Surely This code will help you.
