Télécharger une photo sur Facebook avec Facebook Android SDK dans Android

Je suis nouveau sur Android. Je suis à la recherche de charger la photo à facebook par l'autorisation, l'obtention de access_token. Comment faire cela? Veuillez me donner un exemple de code en Java.

    Vient de poster ici le moyen le plus simple de télécharger une photo:

    android facebook publier la 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
}
}

    voici le code entier de l'essayer, il va sûrement travailler pour vous et c'est un travail pour moi aussi

    La façon la plus simple pour vous est d'utiliser le SDK, quelque chose comme:

    http://github.com/facebook/facebook-android-sdk/

    http://code.google.com/p/fbconnect-android/

    http://wiki.developers.facebook.com/index.php/User:Android

    La plus souple consiste à mettre en œuvre l'API vous-même, voici les documents qui vous seront utiles:

    http://developers.facebook.com/docs/

  4. 3

    Si vous voulez publier une photo avec une description, vous pouvez le faire :

    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);
}

    Avec succès, j'ai téléchargé les photos sur facebook mur
    J'ai utilisé le code suivant.

    Dans votre Activité Principale procédez de la manière suivante;

    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
}
}

    Sûrement Ce code va vous aider.
