hashes de clave facebook android

Question

Soy nuevo en Android. Estoy buscando cargar foto a facebook por autorización, obteniendo access_token. ¿Como hacer esto? Por favor dame un código de muestra en Java.

Answer 1

La forma más fácil para usted es usar el SDK existente, algo así:
http://github.com/facebook/facebook-android-sdk/
http://code.google.com/p/fbconnect-android/
http://wiki.developers.facebook.com/index.php/User:Android

La forma más flexible es implementar la API usted mismo, aquí están los documentos que le serán útiles:

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
}
}

aquí está el código completo, inténtalo, definitivamente funcionará para ti y también es trabajo para mí

Si desea publicar una foto con una descripción, puede hacer esto:

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);
}

Con éxito he subido las fotos en la pared de Facebook. Utilicé el siguiente código.

En tu actividad principal haz lo siguiente;

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
}
}

Seguramente Este código te ayudará.

Acabo de publicar aquí la forma más sencilla de subir una foto:

Facebook de Android publicar foto

Código:

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);
