Android - Tumblr Access Token via OAuth

I am trying to allow Android users to post to their Tumblr blogs using my app. I am able to launch Tumblr, enter my username and password, and log in, however the problem is the Access Token I receive appears to be invalid (I get a 401 - Unauthorized when I use it with any of Tumblr's API calls).
Below is the code I am using. I am able to authenticate with Twitter, but Tumblr is giving me difficulties. If anyone has any ideas, suggestions, or improvements, they would be much appreciated. Thanks!

As it turns out, the Access Token and Access Token Secret returned were valid. The problem was that I was not signing the request with the Access Token Secret.

leaked a window ProgressDialog Android Dropbox

I am trying to upload a file to dropbox via AsyncTask and I am gett the window leaked error:
05-16 16:05:53.523: E/WindowManager(4528): Activity com.example.wecharades.ShowVideo has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView#2be59ea8 that was originally added here
I looked here and understand it is because my activity is exited and the progressdialog is still there. I can't understand why my activity gets exited. it is just a screen with a button to press to upload the file. I am using almost an identical code to download a file from dropbox and it works perfect.
Any suggestions?
thanks in advance!

Try this, in your constructor you dont get the context like this:
dContext=context.getApplicationContext();
but try passing the activity from which you start your asynctask
UploadFile upFile = new UploadFile( ActivityName.this, mDBApi, path);
so in your constructor you have now only:
dContext=context;

call super.onPostExexute(result) after uDialog.dismiss();
#Override
protected void onPostExecute(Boolean result) {
uDialog.dismiss();
Log.d("TAG","UDialog Should be dismissed");
super.onPostExecute(result);
}
EDIT:
ok, I think you should call this code
if(v.getId() == R.id.NoButton){
File file = new File(path);
boolean deleted = false;
deleted = file.delete();
Log.d("TAG", Boolean.toString(deleted));
Intent intent = new Intent(ShowVideo.this, CaptureVideo.class);
startActivity(intent);
}
in the onPostExecute trigger, because it's executed without waiting the AsyncTask to finish. This means you will have to pass the value of the v.getId() so you can achive the same functionality.

Twitter not getting the access token and access token secret Android

I'm implementing twitter tweet message in my Android app. I'm able to implement Twitter log in but I guess I'm not able to save the access token after logging in, because when I tweet a message it doesn't appear to my twitter wall.

Android: Can't post tweet using OAuth and twitter

I am trying to send tweets to twitter via my android app. The libraries I'm using are signpost core, signpost commonshttp, and jtwitter. My code in my main activity is as follows:
public class MainActivity extends Activity implements View.OnClickListener {
static final String TAG = "TweetExample";
private Twitter twitter;
SharedPreferences prefs;
private EditText textStatus;
private static final String CONSUMER_KEY = "my key";
private static final String CONSUMER_SECRET = "my secret";
private static String ACCESS_KEY = null;
private static String ACCESS_SECRET = null;
private static final String REQUEST_URL = "http://twitter.com/oauth/request_token";
private static final String ACCESS_TOKEN_URL = "http://twitter.com/oauth/access_token";
private static final String AUTH_URL = "http://twitter.com/oauth/authorize";
private static final String CALLBACK_URL = "TweetExample://twitt";
private static CommonsHttpOAuthConsumer consumer = new CommonsHttpOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
private static CommonsHttpOAuthProvider provider = new CommonsHttpOAuthProvider
(REQUEST_URL, ACCESS_TOKEN_URL, AUTH_URL);
//Called when the activity is first created.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Retrieve the shared preferences
prefs = getSharedPreferences(USER_PREFERENCES,
Context.MODE_PRIVATE);
// Find views by id
ImageView buttonUpdate = (ImageView) findViewById(R.id.ImageView_Update);
textStatus = (EditText) findViewById(R.id.textStatus);
ImageView btnLogin = (ImageView) findViewById(R.id.ImageView_Twit);
// Add listener
buttonUpdate.setOnClickListener(this);
btnLogin.setOnClickListener(this);
// Initialize preferences
prefs = PreferenceManager.getDefaultSharedPreferences(this);
prefs.registerOnSharedPreferenceChangeListener(new OnSharedPreferenceChangeListener() {
public void onSharedPreferenceChanged(SharedPreferences arg0, String arg1) {
twitter = null;
}
});
}
public void onClick(View v) {
switch(v.getId()){
case R.id.ImageView_Update:
String status = textStatus.getText().toString();
String message = "Status set to: " + status;
Log.d(TAG, message);
// Ignore empty updates
if (status.length() == 0)
return;
// Connect to twitter.com and update your status
try {
Log.d(TAG, "1");
twitter.setStatus(status);
Log.d(TAG, "2");
} catch (TwitterException e) {
Log.e(TAG, "Twitter exception: " + e);
}
Toast.makeText(this, message, Toast.LENGTH_LONG).show();
break;
case R.id.ImageView_Twit:
try {
String authURL = provider.retrieveRequestToken(consumer, CALLBACK_URL);

Log.d(TAG, verifier);
try {
provider.retrieveAccessToken(consumer, verifier);

I know the callback url is right. Could it be that I authenticate using signpost and try to tweet using jtwitter? Right now, I can sign into twitter to authorize the app and get redirected back to my app, but when I type something in to try to post to twitter it gets as far as twitter.setStatus(status);
Any help would be greatly appreciated.

Possibly I'm being blind, or you forgot to include some code, but it looks like the Twitter object is never constructed. So you'd get a NullPointerException when you come to use it.
Somewhere you want code along the lines of:
OAuthSignpostClient oauthClient = new OAuthSignpostClient(app_token, app_secret, user_access_token, user_secret);
Twitter twitter = new Twitter(null, oauthClient);

Twitter OAuth with Android - Still getting a 401 but no glue where the mistake is located

I'm experiencing some problems regarding Twitter OAuth within an android activity. I read a lot of tutorials and example code, but I'm still not able to receive the access token.
Everytime I try to authorize I'm getting this OAuthNotAuthorizedException:
oauth.signpost.exception.OAuthNotAuthorizedException: Authorization failed (server replied with a 401). This can happen if the consumer key was not correct or the signatures did not match.
I googled a lot and it felt like I read thousands of solutions, but none of them worked out for me. Hope you can help me with this one (and I'm not bothering your with the same old newbie question! ;) )
Here is my complete activity code:

The exception is thrown in the onResume()-Method. I marked the exact line. I really hope anyone can help me here. If you need further information just scream!
Thanks!

I finally managed to get the OAuth running. Unless I don't know the exact error. I guess it was some issue with the consumer.
Here is my running code:
onCreate:

pref = Preferences.getPreferences(this);
consumer = new CommonsHttpOAuthConsumer(Key.TW_CONSUMER_KEY,
Key.TW_CONSUMER_SECRET);
provider = new CommonsHttpOAuthProvider(Key.TW_REQUEST_TOKEN_URL,
Key.TW_ACCESS_TOKEN_URL, Key.TW_AUTHORIZE_URL);
provider.setOAuth10a(true);
[...]
if (getIntent().getData() == null) {
checkForSavedLogin();
}
}
onResume:
protected void onResume() {
super.onResume();
Uri uri = getIntent().getData();
if (uri != null
&& Key.TW_CALLBACK_URI.getScheme().equals(uri.getScheme())) {
String token = pref.getString(Key.TW_REQUEST_TOKEN, null);
String secret = pref.getString(Key.TW_REQUEST_SECRET, null);
try {
if (!(token == null || secret == null)) {
consumer.setTokenWithSecret(token, secret);
}
String otoken = uri.getQueryParameter(OAuth.OAUTH_TOKEN);
String verifier = uri.getQueryParameter(OAuth.OAUTH_VERIFIER);
Assert.assertEquals(otoken, consumer.getToken());
provider.retrieveAccessToken(consumer, verifier);
token = consumer.getToken();
secret = consumer.getTokenSecret();
saveAuthInformation(token, secret);
// Delete request information
saveRequestInformation(null, null);
if (!(token == null || secret == null)) {
Log.d(TAG, "Twitter login found!");
consumer.setTokenWithSecret(token, secret);
twitter = new TwitterFactory().getInstance();
twitter.setOAuthConsumer(Key.TW_CONSUMER_KEY,
Key.TW_CONSUMER_SECRET);
twitter.setOAuthAccessToken(new AccessToken(token, secret));
}
} catch (Exception e) {
Log.d(TAG, "Couldn't receive token" + e.getMessage());
e.printStackTrace();

¿Are you using
mHttpOauthprovider = new DefaultOAuthProvider("https://api.twitter.com/oauth/request_token",
"https://api.twitter.com/oauth/access_token",
"https://api.twitter.com/oauth/authorize");
with HTTPS protocol?
