My client side code is identical to what has been posted by jhoffman

I receiving the same error but only when I am not on a WiFi connection. When I am on a decent WiFi connection the file uploads fine using the php script. The file is written just the response from the server is fail, on the non-wifi connection. Any suggestions?

Sambo · by **Sambo** » Tue May 18, 2010 8:07 am

A follow up on my last post, the uploads are failing when I am connected via the T-Mobile Edge network but uploads successfully while on 3G or a wifi connection. I noticed a few other apps unable to upload as well while on the Edge network so I am thinking this issue has to do with Tmobile Edge and not the code.

Everything works fine except from one thing. In my second php file the variable $_SESSION["facebookUid"] is null. I have tried many things but I can't figure out what the problem is. Does anyone have any idea? Any help would be appreciated! Sorry for my English but they are not very good...

The PHP server-side (again, posted earlier in this thread, and not my work, but these two never appear in one single post saying that they work together):
Code: Select all
<?php // Where the file is going to be placed $target_path = "uploads/"; /* Add the original filename to our target path. Result is "uploads/filename.extension" */ $target_path = $target_path . basename( $_FILES['uploadedfile']['name']); if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) { echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded"; } else{ echo "There was an error uploading the file, please try again!"; } ?>

The two things you need to set up in the Java file are: urlString and existingFileName. Configure these such that they match whatever you name your PHP file, and whatever file you're trying to upload. Keep in mind that (as previously posted) you must manually push said file to your emulator's pseudo-SD Card for this to work. (Or have it on a real physical SD card if testing on a real phone). I hope this clears up any confusion that other readers like myself may have in the future!

I need some help. I have a toggle button on/off, all I want it to do is read on or off on my localhost webpage. I did the internet permission in the manifest and created the button in main.xml, here is my java code, all I want is the webpage to simply read On or Off depending on the button push. I'm begging for help, I read through this forum and tried everything and nothing worked, hence the unused imports... Please help!!!!

Can someone please once more explain how exactly do I get the correct path to files?
I'm using jhoffman's code, but my stuff crashes because it can't find the file. I tried using the file explorer to bring test.png into the phone, I also tried opening a browser and downloading the image from the web.
So I should be having the image in two places. I've tried the following paths:
"test.png" "/sdcard/test.png" "/downloads/test.png" "/sdcard/downloads/test.png" yet none of them works.
The application is also crashing on my phone, but not sure if its for the same reason (no logcat over there)

I'm in a little bit of hurry getting this application to work, so any help is very welcome!

I think i might have figured out the path part, at least the application doesn't crash instantly on my phone anymore after i switched to use this:
String existingFileName = Environment.getExternalStorageDirectory().getAbsolutePath() + "/test2.jpg";

But what the application does is it just opens a black screen with the tesxt Hello World, TestUploader! and nothing else happens. Using a html file to test out my php script works just fine, and my php script is identical to the ones posted here so the problem is client side. I've also added INTERNET permission to the androidmanifest file.

The application still crashes on emulator immediately though for not being able to locate the file.

here's the full code:

All we have to do on server's side is to create the .php file, put it into htdocs on Apache folder and start Apache Server? Also, create an "upload" folder in Apache folder.

Do I miss anything? It won't work (the code that many of you tried and worked)

I tried it with pure java code (in my pc) and it worked.

But when I try to run it in Android phone (HTC Desire) I get the following error:

Code: Select all: 01-05 13:40:34.618: ERROR/Got an IOException:(4721): java.net.SocketException: The operation timed out 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at org.apache.harmony.luni.platform.OSNetworkSystem.connectStreamWithTimeoutSocketImpl(Native Method) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at org.apache.harmony.luni.platform.OSNetworkSystem.connect(OSNetworkSystem.java:115) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at org.apache.harmony.luni.net.PlainSocketImpl.connect(PlainSocketImpl.java:244) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at org.apache.harmony.luni.net.PlainSocketImpl.connect(PlainSocketImpl.java:533) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at java.net.Socket.connect(Socket.java:1055) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at org.apache.harmony.luni.internal.net.www.protocol.http.HttpConnection.<init>(HttpConnection.java:62) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at org.apache.harmony.luni.internal.net.www.protocol.http.HttpConnectionPool.get(HttpConnectionPool.java:88) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnectionImpl.getHTTPConnection(HttpURLConnectionImpl.java:927) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnectionImpl.connect(HttpURLConnectionImpl.java:909) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnectionImpl.getOutputStream(HttpURLConnectionImpl.java:1253) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at net.Upload.Upload.onCreate(Upload.java:55) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1069) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2751) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2803) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at android.app.ActivityThread.access$2300(ActivityThread.java:135) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2136) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at android.os.Handler.dispatchMessage(Handler.java:99) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at android.os.Looper.loop(Looper.java:144) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at android.app.ActivityThread.main(ActivityThread.java:4937) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at java.lang.reflect.Method.invokeNative(Native Method) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at java.lang.reflect.Method.invoke(Method.java:521) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) 01-05 13:40:34.618: ERROR/Got an IOException:(4721): at dalvik.system.NativeStart.main(Native Method)

This line is the problem:

Code: Select all: outputStream = new DataOutputStream( connection.getOutputStream() );

it can't get output stream.

Any ideas? Please, I need some help
