Code:
代码：
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
这是整个代码试试看它肯定对你有用，对我也有用

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
对您来说最简单的方法是使用现有的 SDK，类似于：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:
http://developers.facebook.com/docs/
更灵活的方法是自己实现 API，这里是有用的文档：http:

我成功地将照片上传到了 facebook 墙上，我使用了以下代码。
In your Main Activity do the following;
在您的主要活动中执行以下操作；
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.
当然这段代码会帮助你。

If you want to publish a photo with a description you can do this :
如果您想发布带有描述的照片，您可以这样做：
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);
}
