I am trying to get my webview to show a page that is only accesible after i am logged in. but whatever i try i cant get past the login url.
How can i open/show the SEND_VISUM_URL after i login.
this is what i have so far:
String LOGIN_URL = "http://10.35.50.125/BCS/index.php?module=";
String SEND_VISUM_URL = "http://10.35.50.1/BCS/index.php?module=ScanVisa&Action=save";

HttpClient is not supported any more in sdk 23. You have to use URLConnection or downgrade to sdk 22 (compile 'com.android.support:appcompat-v7:22.2.0')
If you need sdk 23, add this to your gradle:
android {
useLibrary 'org.apache.http.legacy'
}
HttpClient won't import in Android Studio
You should think about using a HTTP library, there is a bunch of them on internet, some are really easy to use, optimize and errorless.
For example, Volley (made by Google, I really like this one), okHttp or Picasso (for image).
You should take a look at this.
If you want to send (output), for example with POST or PUT requests you need to use this :-
urlConnection.setDoOutput(true);
In your code :-
public class Login extends AsyncTask<String, Void, String>{
private String loginUrl = "http://...";
private int loginSuccess = 0;
public String getToken(String fromJson) throws JSONException {
JSONObject json = new JSONObject(fromJson);
if(json.has("api_authtoken")) {
loginSuccess = 1;
String appToken = json.getString("api_authtoken");
return appToken;
}
else {
return json.toString();
}
}

I am trying to post a photo from an url to the facebook. So, I have a method that converts the image located in the provided url to a bitmap, after that I want to publish the image to the facebook photos of the user. This is my code:
Method that converts image located in a URL to a Bitmap image:
public Bitmap downloadImage(String url) {
Bitmap bm = null;
try {
URL aURL = new URL(url);
URLConnection conn = aURL.openConnection();
conn.connect();
InputStream is = conn.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
bm = BitmapFactory.decodeStream(bis);
bis.close();
is.close();
} catch (IOException e) {
Log.e("Hub","Error getting the image from server : " + e.getMessage().toString());
}
return bm;
}
This is where I try to post the image in the facebook:
private void postToFacebook(byte[] data) {
Session session = Session.getActiveSession();
if (session != null) {
Bundle postParams = new Bundle();
postParams.putString("caption", "Teste caption");
postParams.putByteArray("picture", data);
Request.Callback callback = new Request.Callback() {
public void onCompleted(Response response) {
JSONObject graphResponse = response.getGraphObject().getInnerJSONObject();
String postId = null;
try {
postId = graphResponse.getString("id");
} catch (JSONException e) {
Log.i("", "JSON error "+ e.getMessage());
}
FacebookRequestError error = response.getError();
if (error != null) {
Toast.makeText(getContext(), error.getErrorMessage(), Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getContext(), postId, Toast.LENGTH_LONG).show();
}
}
};
Request request = new Request(session, "me/photos", postParams, HttpMethod.POST, callback);
RequestAsyncTask task = new RequestAsyncTask(request);
task.execute();
} else {
Toast.makeText(getContext(), "Not logged", Toast.LENGTH_SHORT).show();
}
But at this line: response.getGraphObject(), I am getting the null pointer exception. I've tried to execute in a background thread, like this:
class ConvertImageTask extends AsyncTask<URL, Integer, byte[]> {
AsyncTask<Params,Progress,Result>
#Override
protected void onPreExecute() {
super.onPreExecute(); // do nothing here
}
#Override
protected byte[] doInBackground(URL... params) {
byte[] data;
Bitmap bi = downloadImage(getPhotoUrl());
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bi.compress(Bitmap.CompressFormat.PNG, 100, baos);
data = baos.toByteArray();
return data;
}
#Override
protected void onPostExecute(byte[] result) {
postToFacebook(result);
}
But the error continues.
How can I fix this?
Thank you!
The pages I've gone through show the "picture" parameter is a URL, not data you can upload from your computer.
To upload a photo I am using:
Request request = Request.newUploadPhotoRequest(Session.getActiveSession(),
BitmapFactory.decodeStream(this.getAssets().open("YourFile.png")),
new Request.Callback(){
#Override
public void onCompleted(Response response) {
FacebookRequestError error = response.getError();
if(error != null){
Log.i(this.getClass().getName(),"Error publishing.");
}else{
JSONObject graphResponse = response.getGraphObject().getInnerJSONObject();
String postId = null;
try {
postId = graphResponse.getString("id");
} catch (JSONException e) {
Log.i("Facebook error", "JSON error " + e.getMessage());
}
//Logged in Succesfully!
}
}
});
Bundle params = request.getParameters();
params.putString("name", "The title for the photo.");
request.setParameters(params);
request.executeAsync();
I am passing a png I have in my assets folder, but you can adapt that part to what you need. Looking at your code it should be straight forward.
One assumed using the Tumblr API to upload images would be easy. It isn't. (EDIT It is now, see Edit 2 at the end of this entry)
My app is supposed to upload an image to tumblr. I would prefer doing that from a service but for now I use an activity that closes itself as soon as its done uploading. In OnCreate() the user is authenticated:
consumer = new CommonsHttpOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
// It uses this signature by default
// consumer.setMessageSigner(new HmacSha1MessageSigner());
provider = new CommonsHttpOAuthProvider(REQUEST_TOKEN_URL,ACCESS_TOKEN_URL,AUTH_URL);
String authUrl;
try
{
authUrl = provider.retrieveRequestToken(consumer, CALLBACK_URL);
Log.d(TAG, "Auth url:" + authUrl);
startActivity(new Intent("android.intent.action.VIEW", Uri.parse(authUrl)));
}
This opens a browser activity where the user can add username and passoword and then the app returns to the activity (this is also why I have to use an activity, I don't know how to do this from a service)
Returning from the browser the data is extracted:
Uri uri = context.getIntent().getData();
if (uri != null && uri.toString().startsWith(CALLBACK_URL))
{
Log.d(TAG, "uri!=null");
String verifier = uri.getQueryParameter("oauth_verifier");
Log.d(TAG, "verifier"+verifier);
try
{
provider.setOAuth10a(true);
provider.retrieveAccessToken(consumer, verifier);
Log.d(TAG, "try");
}
catch (Exception e)
{
Log.e(TAG, e.toString());
e.printStackTrace();
}
OAUTH_TOKEN = consumer.getToken();
OAUTH_SECRET = consumer.getTokenSecret();
Most of these two snippets I got from here and they work well.
With these tokens I can now try putting data on tumblr. When I try to add Text this works fine using this method:
private void createText()
{
if(!OAUTH_TOKEN.equals(""))
{
HttpContext context = new BasicHttpContext();
HttpPost request = new HttpPost("http://api.tumblr.com/v2/blog/" + blogname + ".tumblr.com/post");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("type", "text"));
nameValuePairs.add(new BasicNameValuePair("body", "this is just a test"));
try
{
request.setEntity(new UrlEncodedFormEntity(nameValuePairs));
}
catch (UnsupportedEncodingException e1)
{
Log.e(TAG, e1.toString());
e1.printStackTrace();
}
if (consumer == null)
{
consumer = new CommonsHttpOAuthConsumer(OAuthConstants.TUMBR_CONSUMERKEY, OAuthConstants.TUMBR_SECRETKEY);
}
if (OAUTH_TOKEN == null || OAUTH_SECRET == null)
{
Log.e(TAG, "Not logged in error");
}
consumer.setTokenWithSecret(OAUTH_TOKEN, OAUTH_SECRET);
try
{
consumer.sign(request);
}
catch (OAuthMessageSignerException e)

PostToTumblr.this.finish();

As you can see here http://www.tumblr.com/blog/snapnowandroid (at least as of this time) the text "this is just a test" is posted.
However, when I try to post images, it gets strange. Now I have checked around and apparently this is a well known issue with the tumblr API, which has excessively been discussed here and some have solved it in other programming languages (for example here) but I have been unable to repeat those successes.
The method (in its entirety below) has the exact same structure to the above method (that works), the nameValuePairs are just different
The method is given a Bitmap variable called photo:
private void uploadToTumblr(Bitmap photo)
This bitmap is converted into an array:
ByteArrayOutputStream stream = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] bytes = stream.toByteArray();
The nameValuePairs are filled as follows:
nameValuePairs.add(new BasicNameValuePair(URLEncoder.encode("type", enc), URLEncoder.encode("photo", enc)));
nameValuePairs.add(new BasicNameValuePair(URLEncoder.encode("caption", enc), URLEncoder.encode(text, enc)));
nameValuePairs.add(new BasicNameValuePair("data", Base64.encodeToString(bytes, Base64.URL_SAFE)));
The result is a {"meta":{"status":400,"msg":"Bad Request"},"response":{"errors":["Error uploading photo."]}} from the tumblr api.
I have tries encoding the picture differently as discribed in this article but without any changes.
//http://www.coderanch.com/t/526487/java/java/Java-Byte-Hex-String
final char[] hexArray = {'0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F'};
char[] hexChars = new char[bytes.length * 3];
int v;
for ( int j = 0; j < bytes.length; j++ )
{
v = bytes[j] & 0xFF;
hexChars[j * 3] = '%';
hexChars[j * 3 + 1] = hexArray[v >>> 4];
hexChars[j * 3 + 2] = hexArray[v & 0x0F];
}
String s = new String(hexChars);
s = URLEncoder.encode(s, enc);
nameValuePairs.add(new BasicNameValuePair(URLEncoder.encode("data", enc), s));
Here the entire method (without the hex encoding):
private void uploadToTumblr(Bitmap photo)
{
if(!OAUTH_TOKEN.equals(""))
{
ByteArrayOutputStream stream = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] bytes = stream.toByteArray();
String text ="SNAP";
HttpContext context = new BasicHttpContext();
HttpPost request = new HttpPost("http://api.tumblr.com/v2/blog/" + blogname + ".tumblr.com/post");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
String enc = "UTF-8";
try
{
nameValuePairs.add(new BasicNameValuePair(URLEncoder.encode("type", enc), URLEncoder.encode("photo", enc)));
nameValuePairs.add(new BasicNameValuePair(URLEncoder.encode("caption", enc), URLEncoder.encode(text, enc)));
nameValuePairs.add(new BasicNameValuePair("data", Base64.encodeToString(bytes, Base64.URL_SAFE)));
}

Now, while there are several things I am unhappy with (for example that this is done using an activity instead of a service) the big issue here is clearly the problem of uploading images. I am by no means the first to have this problem, so has anyone been able to get this done in java?
Edit 1
Have not made any progress with the problem at hand but created a workaround that might be nice for people who have the same issue. Tumblr offers posting via mail and you can programm android to send emails in the background as shown here. This works very well but you need to ask users to provide their mail account data and the Tumblr-mail Adress to post.
Edit 2
Years have pased and using email is no longer the easy way to do it. With jumblr there is finally a good API for Java that will work on android. OAuth-Authentication is no fun (it never is) but once you get past this, its fantastic.
Now, technically the question of how to do the authentication does not belong here but It's my overly long question, so I'll just paste some code here and if it's not interesting to you just skip it.
This uses a jar called jumblr-0.0.10-jar-with-dependencies.jar

Why don't you use Jumblr the official Java client for Tumblr.
Regards.
You can easily do this using jumblr - Tumblr java client
JumblrClient client = new JumblrClient(Constant.CONSUMER_KEY,Constant.CONSUMER_SECRET);
client.setToken(preferences.getString("token",null), preferences.getString("token_secret", null));
PhotoPost pp = client.newPost(client.user().getBlogs().get(0).getName(),PhotoPost.class);
pp.setCaption(caption);
// pp.setLinkUrl(link);
// pp.setSource(mImage); // String URL
pp.setPhoto(new Photo(imgFile));
pp.save();
This worked for me...
nameValuePairs.add(new BasicNameValuePair(URLEncoder
.encode("type", "UTF-8"),
URLEncoder.encode("photo", "UTF-8")));
Log.e("Tumblr", "Image shareing file path" + filePath);
nameValuePairs.add(new BasicNameValuePair("caption", caption));
nameValuePairs.add(new BasicNameValuePair("source", filePath));`
where filePath is http url.

I have done using following method. you can try this.

HttpPost localHttpPost = new HttpPost("http://api.tumblr.com/v2/blog/" + str1 + ".tumblr.com/post");
try
{
ArrayList localArrayList = new ArrayList();
localArrayList.add(new BasicNameValuePair("type", "photo"));
BasicNameValuePair localBasicNameValuePair = new BasicNameValuePair("caption", paramString);
localArrayList.add(localBasicNameValuePair);
localArrayList.add(new BasicNameValuePair("data",encodedImage));
UrlEncodedFormEntity localUrlEncodedFormEntity = new UrlEncodedFormEntity(localArrayList);
localHttpPost.setEntity(localUrlEncodedFormEntity);
localCommonsHttpOAuthConsumer.sign(localHttpPost);
InputStream localInputStream = localDefaultHttpClient.execute(localHttpPost).getEntity().getContent();
InputStreamReader localInputStreamReader = new InputStreamReader(localInputStream);
BufferedReader localBufferedReader = new BufferedReader(localInputStreamReader);
StringBuilder localStringBuilder = new StringBuilder();
while (true)
{
String str2 = localBufferedReader.readLine();
if (str2 == null)
{
Log.i("DATA post resp", localStringBuilder.toString());
break;

localStringBuilder.append(str2);
}

EDIT : First Upload image to Web Server then get Url and try to Post with uploaded Url or File path. it will work fine sure... :)
I am working with Android http stuff to register/unregister to the server. I have a DELETE request to use HttpDelete. I am getting Http401 'Bad request' error when I try to call it. I cannot why it is happening. Please help me.
Here is my code:
HttpUtils.java
private BasicHttpParams mParams;
private UsernamePasswordCredentials mCredentials = null;
private ResponseHandler mResponseHandler = null;
public void setUserCredentials(String userName, String password) {
this.mCredentials = new UsernamePasswordCredentials(userName, password);
}
public void setResponseHandler(ResponseHandler responseHandler){
this.mResponseHandler = responseHandler;
}
public Result<String> delete(String url){
Result<String> result = new Result<T>();
result.setStatus(Result.FAIL);
try {
DefaultHttpClient httpClient = new DefaultHttpClient(mParams);
httpClient.setParams(mParams);
httpClient.getCredentialsProvider().setCredentials(new AuthScope(null, -1), mCredentials);
HttpResponse response = httpClient.execute(new HttpDelete(url));
result.setResult(mResponseHandler.handleResponse(response));
result.setStatus(Result.SUCCESS);
} catch (IllegalArgumentException e) {
e.printStackTrace();
result.setMessage(e.getMessage());
} catch (ClientProtocolException e) {
e.printStackTrace();
result.setMessage(e.getMessage());
} catch (ConnectTimeoutException e) {
result.setMessage("Connection timed out.");
} catch (IOException e) {
e.printStackTrace();
result.setMessage(e.getMessage());
}
return result;
}
UnregisterTask.java
#Override
protected Void doInBackground(String... urls) {
if (urls==null || urls.length!=1)
return null;
String url = urls[0];
HttpUtils httpUtils = new HttpUtils();
httpUtils.setUserCredentials("userid", "password");
httpUtils.setResponseHandler(new UnrgisterHandler());
httpUtils.delete(url);
Result<String> result = aClient.delete(url);
if (result!=null || result.result != null){
//Do Something
}
}
//UnrgisterActivity.java
public void onUnregisterButtonClick(View view){
UnregisterTask task = new UnregisterTask(this);
task.execute(ServerConfig.getIdmServer() + ServerConfig.DELETE_DEVICE + "myid");
}
Error recevied:
Apache Tomcat/7.0.26 - Error report HTTP Status 400 - type Status reportmessage description The request sent by the client was syntactically incorrect ().Apache Tomcat/7.0.26
Thanks in Advance.
I fixed it by myself but I do not understand clearly why the error happened. I changed my code after searching how to set basic authentication.
public Result<T> delete(String url)
Result<T> result = new Result<T>();
result.setStatus(Status.FAIL);
try {
DefaultHttpClient http = new DefaultHttpClient();
if (this.mCredentials!=null){
CredentialsProvider credProvider = new BasicCredentialsProvider();
credProvider.setCredentials(new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT), this.mCredentials);
http.setCredentialsProvider(credProvider);
}
HttpDelete delete = new HttpDelete(url);
//delete.setEntity(new StringEntity(data, "UTF8"));
delete.addHeader("Content-type", JSON_TYPE);
HttpResponse response = http.execute(delete);
result.setResult(mResponseHandler.handleResponse(response));
result.setStatus(Result.Status.SUCCESS);
} catch (IllegalArgumentException e) {
e.printStackTrace();
result.setMessage(e.getMessage());
} catch (ClientProtocolException e) {
e.printStackTrace();
result.setMessage(e.getMessage());
} catch (ConnectTimeoutException e) {
result.setMessage("Connection timed out.");
} catch (IOException e) {
e.printStackTrace();
result.setMessage(e.getMessage());
}
return result;
}
A bit still confusing. Anyway, now it works charm.
