thankyou

[Don Ho]

What does logcat say?

[Peter Johnson]

And please post the code you are using to do the upload.

[Andrew Moko]

We need to view your code.

The java program doing the upload uses a set of libraries/ apis which OBVIOUSLY don't work in android.

Alternatively, fire-up another file upload app (with startActivity) and receive the response in your logic..

[Ben Alex Barreto]

There are several things that could be causing that. Can we see your code? Make sure you set the right permissions in the manifest, such as internet access for example.

[Suzzane Pinto]

thankyou for the reply,

i am using andriod 2.1,i have posted my code here
jar i have used is:(org.apache.commons.net_2.0.0.v200905272248.jar)
i have also given the internet permission in manifest file.
please see through the code and help because iam unsuccessful to do this since long

Is this problem only in emulator??

[Tim Moores]

Caused by: java.lang.ClassNotFoundException: myapp.test.AndriodTestActivity

Does your app have such a class? The code you posted doesn't.

[Don Ho]

Could you also post your AndroidManifest.xml?

[Suzzane Pinto]

dat log cat i posted was different.sory for wrong post..
please see the code and tell me what could be wrong.is this problem of version or emulator?

What problem? Is there an exception? If so, post the logcat output. If there's no exception, tell us what the code does right now, and how that differs from what you expected it to do.

i want to send the image i select from the sdcard to the ftp server i mentioned.
the problem is the image is not uploaded to the server.
i am running on android version 4.0.3


please suggest

[Swastik Dey]

Look at the error log, it says could not connect to host 67.15.35.194.

[Suzzane Pinto]

can you tell what might be the reason..??
is something wrong in the coding?

iam unable to resolve for a while now

[Tim Moores]

It's a network problem. Can you ping that host from the device?

[Swastik Dey]

As Tim has said it's a network issue, and port 8080 is typically a http port. Try to connect using the default ftp port.

[Suzzane Pinto]

how to ping on a virtual device?

[Suzzane Pinto]

i changed the port to 21 now still it is not working..

[Swastik Dey]

Does the error log say same?

I hope the password you quoted earlier is a dummy password; if no you ought to go back and change the post.
Please don’t post long lines in code tags; I have had to edit your stack traces so they are legible without too much left and right scrolling.

There are any number of Ping apps in the Android Market; some of them are bound to be available as .apk files from their developers in case you don't have access to the Android Market.

[Suzzane Pinto]

unable to get the exception in the logcat?

[Swastik Dey]

print a stack trace, this might give a better explanation of the cause

catch(Exception e) {  
        
         Log.d(TAG, "Error: could not connect to host " + host );  
         e.printStackTrace();
       }

So which object is null?

[Suzzane Pinto]

m not getting it.....

[Andrew Moko]

at com.myapp.test.ProgressInputStream.sendLong(ProgressInputStream.java:76)

[Andrew Moko]

I don't see the Handler progressHandler in the MainActivity class being initialized. Learn to read and follow through the error stack messages.

now i am able to uplaod images from emulator,but while i run in my mobile device the image is not uploaded...
i recognized that the problem is in getting the absolute path of image before uploading....can you tell me hw to get the image from relative path???

[Tim Moores]

This should help: http://developer.android.com/guide/topics/data/data-storage.html#filesExternal

[Suzzane Pinto]

my problem is he app is running fine on virtual device but not in the actual device.
what might be the problem???
when i run from my avd it takes image from the sdcard n then send to server. but in mobile it allows to select from its sdcard and when selected it doesnt upload


any idea why is it so??

[Swastik Dey]

Does the device has a proper network connectivity?

[Tim Moores]

At which step of the code does the execution start to differ on the real device?

[Suzzane Pinto]

nw it is running from device also i just used following code

public static String getLastBitFromUrl(final String url){
	    // return url.replaceFirst("[^?]*/(.*?)(?:\\?.*)","$1);" <-- incorrect
	    return url.replaceFirst(".*/([^/?]+).*", "$1");
	}

  boolean result = ftpClient.storeFile(getLastBitFromUrl(
              	        var), progressInput);
 

now i observed that...images from mobile are loaded incompltly(half image)...whereas from avd upto image sized upto 7b where loaded successfully
is size a problem or something else?

[Suzzane Pinto]

can anyone reply to my post...
will adding progress bar solve my problem of loading incomplete img.....
what can be done??

[Tim Moores]

A progress bar is just for providing user feedback; it has no bearing on the actual operation.

What about the question I asked earlier?

[Suzzane Pinto]

Actually i observed later that both from the avd and the mobile images greater than 7kb are not getting uploaded...
i need some solution over that..

[Suzzane Pinto]

will creating a diff thread solve my problem?? may be the UI thread is not taking load....
please correct if i am wrong and do suggest something

[Tim Moores]

Lengthy operations should definitely not be run in the UI thread. That's what AsyncTask is for: http://developer.android.com/resources/articles/painless-threading.html, http://mobileorchard.com/android-app-developmentthreading-part-2-async-tasks/
