I need to display an image in my android application. The problem is I want to get this image from somewhere online. The URL is like:
http://www.mydomain.com/hello world image.png
As you see the image name containing some spaces in it. Every time I execute my code this will show me exception of FileNotFound. and nothing happens.
Following is my code
String imagePathCon = "hello world image.png";
String imagePath = "http://www.mydomain.com/" + imagePathCon;
try {
URL url;
url = new URL(imagePath);
// url = new URL("http://www.azuma-kinba.com/wp-content/uploads/2012/05/Android-Make-Google-Loss-in-2010.png");
InputStream content = (InputStream)url.getContent();
Drawable d = Drawable.createFromStream(content , "src");
im.setImageDrawable(d);
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
I use to replace space with "+" but nothing happens.
This will work.
String imagePathCon = "hello world image.png";
imagePathCon=imagePathCon.replaceAll(" ", "%20");
String imagePath = "http://www.mydomain.com/" + imagePathCon;
You must know http://en.wikipedia.org/wiki/Percent-encoding#Character_data
plese use correct Url for getting image and use below code that would definetly help u...
replace space of URL using...
imagePath=imagePath.replaceAll(" ", "%20");
and now...
HttpGet httpRequest = new HttpGet(new URL(params[0]).toURI());
HttpClient httpClient = new DefaultHttpClient();
HttpResponse response = (HttpResponse) httpClient.execute(httpRequest);
HttpEntity entity = response.getEntity();
BufferedHttpEntity bufHttpEntity = new BufferedHttpEntity(entity);
InputStream is = bufHttpEntity.getContent();
//image_value = new URL("image Url is here");
bm = BitmapFactory.decodeStream(new FlushedInputStream(is));
//imageLoader is object of iamge view
imageLoader.setImageBitmap(bm);
You need to url encode the path, like this:
String imagePathCon = URLEncoder.encode("hello world image.png", "UTF-8");
You can also use an http get request:
The simplest way is to simply call URLEncoder which will automatically replace all charaters in your string to the url encoded format.
HttpParams httpParameters = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParameters, 30000);
HttpConnectionParams.setSoTimeout(httpParameters, 30000);
HttpClient httpclient = new DefaultHttpClient(httpParameters);
HttpGet httpGet = new HttpGet(URLEncoder.encode(url, "UTF-8"));
HttpResponse httpResponse = httpclient.execute(httpGet);
in = httpResponse.getEntity().getContent();
//Bitmap bmp = BitmapFactory.decodeStream(instream);
//create a bitmap or an image from the input stream

I am working on an app that allows the user upload an image by using HttpPost method. I use MultipartEntity and therefore I added the libraries apache-mime4j-0.6.1.jar, httpclient-4.3.1.jar, httpcore-4.3.1.jar and httpmime-4.2.1.jar into my app. My upload code is like below:
public String uploadFile() throws Exception
{
String result = "";
try
{
HttpResponse response = null;
HttpClient httpClient = new DefaultHttpClient();
HttpPost request = new HttpPost(_url);
request.setHeader("Accept", "application/json");
File file=new File(filePath);
String fileName=file.getName();
MultipartEntity imageEntity=new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE,null,Charset.forName("UTF-8"));
imageEntity.addPart("imageName", new StringBody(fileName));
imageEntity.addPart("image", new FileBody(file, "application/octet-stream"));
request.setEntity(imageEntity);
response = httpClient.execute(request);
InputStream dataStream = response.getEntity().getContent();
BufferedReader dataReader = new BufferedReader(new InputStreamReader(dataStream));
String line = "";
while ((line = dataReader.readLine()) != null)
result+=line;
}
catch (Exception e)
{
}
return result;
}
I get response from my server but in my web service code Request.Files has no file. If I change the line:
MultipartEntity imageEntity=new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE,null,Charset.forName("UTF-8"));
to
MultipartEntity imageEntity=new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
app is in process for a long time (about 3-4 minutes) and throws error. This is caused if I add an image. If I send only StringBody without FileBody, I get response from server and Request.Files in my webservice code return file count correctly. How can I fix this problem and upload image correctly? Any suggestion?

Load image from url
(17 answers)
Closed 9 years ago.
With Android Studio I have a code that displays images from a direct URL.
I want that displays all the images from a site (they are item called <enclosure/>) and put that in my Custom ListView. So I get the String of the URLs where is present the image and then show it by the code below but I get nothing. Can you help me?
TextView txtImage = (TextView)rowView.findViewById(R.id.item_image);
txtImage.setText(web.get(position).getEnclosure());
txtImage.setTypeface(myTypeface);
ImageView img = (ImageView) rowView.findViewById(R.id.enclosure);
try {
URL url = new URL(context.getString(R.id.item_image));
HttpGet httpRequest = null;
httpRequest = new HttpGet(url.toURI());
HttpClient httpclient = new DefaultHttpClient();
HttpResponse response = (HttpResponse) httpclient
.execute(httpRequest);
HttpEntity entity = response.getEntity();
BufferedHttpEntity b_entity = new BufferedHttpEntity(entity);
InputStream input = b_entity.getContent();
Bitmap bitmap = BitmapFactory.decodeStream(input);
img.setImageBitmap(bitmap);
} catch (Exception ex) {
}
This is all you need to do:
URL url = new URL("http://image10.bizrate-images.com/resize?sq=60&uid=2216744464");
Bitmap bmp = BitmapFactory.decodeStream(url.openConnection().getInputStream());
imageView.setImageBitmap(bmp);
It's not recommended to do this on the UI thread, as it blocks, but you can do it in an AsyncTask.
I am downloading images from URL, but there are spaces in URL so its skipping thoses URL.
I have gone through several arcticles, which mentioned replace space with %20 or +, both the approach are not working. So what are the alternatives now.
Log.i("CountryFlagThumb", VArray.get(2).replaceAll(" ", "%20"));
http://id8lab.net/WorldNewsApp/flags/United Arab Emirates.png
Thanks
You don't encode the entire URL, only parts of it that come from "unreliable sources".
String data = URLEncoder.encode("United Arab Emirates.png", "utf-8");
String url = "http://id8lab.net/WorldNewsApp/flags/" + data;
You just Encode your url like
String url =Uri.encode("http://id8lab.net/WorldNewsApp/flags/United Arab Emirates.png")
Hope this will help.
To download image from url use the following,
HttpGet httpRequest = new HttpGet(URI.create(path) );
HttpClient httpclient = new DefaultHttpClient();
HttpResponse response = (HttpResponse) httpclient.execute(httpRequest);
HttpEntity entity = response.getEntity();
BufferedHttpEntity bufHttpEntity = new BufferedHttpEntity(entity);
Bitmap bmp = BitmapFactory.decodeStream(bufHttpEntity.getContent());
httpRequest.abort();
I got an error using HttpPost for sending an MMS in Android.
In the Logcat it says:
ERROR/Here(447): ---------Error-----Target host must not be null, or set in parameters.
My sample code:
String url = "myurl";
HttpClient httpClient = new DefaultHttpClient();
try {
httpClient.getParams().setParameter(url, new Integer(90000)); // 90 second
HttpPost post = new HttpPost(url);
File SDCard = Environment.getExternalStorageDirectory();
File file = new File(SDCard, "1.png");
FileEntity entity;
entity = new FileEntity(file,"binary/octet-stream");
entity.setChunked(true);
post.setEntity(entity);
post.addHeader("Header", "UniqueName");
Log.i("MMSHTTP","----post---------------"+post);
HttpResponse response = httpClient.execute(post);
if (response.getStatusLine().getStatusCode() != HttpStatus.SC_OK) {
Log.e("Here",
"--------Error--------Response Status line code:" + response.getStatusLine());
}
else
{
// Here every thing is fine.
}
HttpEntity resEntity = response.getEntity();
if (resEntity == null) {
Log.e("Here","---------Error No Response!!-----");
}
} catch (Exception ex) {
Log.e("Here","---------Error-----"+ex.getMessage());
ex.printStackTrace();
} finally {
httpClient.getConnectionManager().shutdown();
}
How do I fix the error?
The url you're specifying is in your sample code is:
String url = "myurl";
In order for HttpClient to be able to determine the host name, you're going to need to supply a valid url. Something along the lines of:
String url = "http://myurl.com/index";
Note: The 'http://' is important so that the appropriate protocol can be determined.
This guy had the same problem.
I've been looking into this for the last day or two and can not seem to find a solution to my issue. I am trying to post an image to a server using httppost.
I have tried two ways of doing this and both complete the post but with no content i.e. the content length is 0.
The first is as follows:
String url = "MYURL";
HttpClient httpClient = new DefaultHttpClient();
try {
httpClient.getParams().setParameter("http.socket.timeout", new Integer(90000)); // 90 second
HttpPost post = new HttpPost(url);
File SDCardRoot = Environment.getExternalStorageDirectory();
File file = new File(SDCardRoot,"/DCIM/100MSDCF/DSC00004.jpg");
FileEntity entity;
entity = new FileEntity(file,"binary/octet-stream");
entity.setChunked(true);
post.setEntity(entity);
post.addHeader("Header", "UniqueName");
HttpResponse response = httpClient.execute(post);
if (response.getStatusLine().getStatusCode() != HttpStatus.SC_OK) {
Log.e("Here","--------Error--------Response Status line code:"+response.getStatusLine());
}else {
// Here every thing is fine.
}
HttpEntity resEntity = response.getEntity();
if (resEntity == null) {
Log.e("Here","---------Error No Response!!-----");
}
} catch (Exception ex) {
Log.e("Here","---------Error-----"+ex.getMessage());
ex.printStackTrace();
} finally {
httpClient.getConnectionManager().shutdown();
}
and the second is:
String url = "MYURL";
//File SDCardRoot = Environment.getExternalStorageDirectory();
File file = new File(Environment.getExternalStorageDirectory(),"/DCIM/100MSDCF/DSC00004.jpg");
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
InputStreamEntity reqEntity = new InputStreamEntity(new FileInputStream(file), -1);
reqEntity.setContentType("binary/octet-stream");
reqEntity.setChunked(true);
// Send in multiple parts if needed
httppost.setEntity(reqEntity);
HttpResponse response = httpclient.execute(httppost);
Log.d("finishing", "The try catch function");
} catch (Exception e) {
// show error
}*/
As you can see I have hardcoded a path to a specific image, this is to be dynamic when I get it up and running.
Can anyone see what i'm doing wrong? Am I leaving out something? I know I use setChunked and setContenttype - is there a setContent option?
Any help would be grately appreciated.
Thanks,
jr83.
You can use upload your image by sending multipart messages; you might find this discussion useful.
