Two ways to upload photo to Facebook

Graph and REST

1. Use Graph
/ALBUM_ID/photos
This way needs album id to upload a photo within a album.


Bundle params = new Bundle();
Uri uri = (from somewhere)
byte[] data = null;

InputStream is = mContext.getContentResolver().openInputStream(uri);
data = new byte[is.available()];
is.read(data);

if (data != null) {
    params.putString("message", "test");
    params.putByteArray("source", data);
    String response = Facebook.request(ALBUM_ID/photos, params, "POST");
}


2. Use REST
photos.upload
This doesn't need a album id, instead it creates a album with your application name if there doesn't exist one.


Bundle params = new Bundle();
Uri uri = (from somewhere)
byte[] data = null;

InputStream is = mContext.getContentResolver().openInputStream(uri);
data = new byte[is.available()];
is.read(data);

if (data != null) {
    params.putString("method", "photos.upload");
    params.putByteArray("picture", data);
    String response = Facebook.request(null, params, "POST");
}

    }
    else {

Instant Upload on Google+

I am using Google+, its a complete socail environment.

I love the circles (just imagine t a movie "Litte Fockers" , Robert always says the "circle")

Now you can choose who can be in your circle!

As title I am talking the Instant Upload.

It will observe your pictures taken by camera and upload it if you ckeck the option in settings.

You can also choose upload via mobile network or wifi for each photos and videos.

Be noticed, it upload to instant album only.

Before this, HTC Sense (like Chacha & Salsa) has this function named "Auto Backup" and much well design.

Now HTC Sense supports two two Services as Facebook and Flickr.

Each service you can select a default album you want to upload.

Besides Instant Upload and only upload via Wifi, HTC Sense supports "Scheduler Upload".

You could set a daily scheduler to upload your photos on time.

This allows you upload photos when you are sleeping while the phone is charged.

It will not influence your internet speed, phone performance, and don't worry about battery dead.

If you have any suggestions on Auto Backup, please give me some feedback.

I'll improve it.

Thanks.
