When Webservice is called

Java.net. SocketException: Permission denied (maybe missing INTERNET permission)

Cause:

To access the network, you must configure the following in AndroidManifest. xml:

<Uses-permission android: name = "android. permission. INTERNET"/>

Error Message]

Org. xmlpull. v1.XmlPullParserException: expected: START_TAG {cursor (position: START_TAG <{export targetNamespace = 'HTTP: // taobao'> @ 2: 603 injava. io. InputStreamReader @ 44a3a7b0)

The cause may be one of the following:

1) The Soap version of the Webservice server is 1.0, so the client specifies

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope (SoapEnvelope. VER11 );

Change VER11 to VER10

2) String serviceUrl = "http: // 200.200.200.11: 10000/nqbx/service/InqBxWebService? Wsdl ";

The Url refers to the address of your webservice. Generally, it is ***. wsdl or ***.? The wsdl ends... but it should be noted that the. wsdl or .? Wsdl

In the new Thread, public class HttpThread extends Thread {...}

Add a pop-up form:

New AlertDialog. builder (this ). setTitle ("data loading failed "). setMessage ("Check network connection "). setPositiveButton ("OK", new DialogInterface. onClickListener () {public void onClick (DialogInterface dialoginterface, int I ){}}). show ();

Cause and solution:

// The UI cannot be operated in the thread

Java. lang. RuntimeException: Can't create handler inside thread that has not called logoff. prepare ()

After modification:

New AlertDialog. builder (com. nantsing. infoquery. chuanbo_detail.this ). setTitle ("data loading failed "). setMessage ("Check network connection "). setPositiveButton ("OK", new DialogInterface. onClickListener () {public void onClick (DialogInterface dialoginterface, int I ){}

Error Message]

The constructor AlertDialog. Builder (chuanbo_detail.HttpThread) is undefined

Cause and solution:

You cannot control the UI components beyond the main UI thread. Because you must use various methods to display various prompt messages after the new thread task is completed by sending a message notification task to the UI main thread.

There are multiple communication methods between threads. handler is often used to transmit messages.

As follows:

Construct a message in the thread:

// Construct the Message message = handle. obtainMessage (); Bundle B = new Bundle (); B. putString ("tag", "1"); message. setData (B); handle. sendMessage (message );

In addition, custom messages:

/*** Capture the Message Queue fubin. pan 2011-04-02 */Handler handler = new Handler () {public void handleMessage (Message m) {if (! M. getData (). getString ("tag "). equals ("1 ")){...} else {new AlertDialog. builder (chuanbo_detail.this ). setTitle ("data loading failed "). setMessage ("Check network connection status! "). SetPositiveButton (" OK ", new DialogInterface. OnClickListener () {public void onClick (DialogInterface dialoginterface, int I) {}}). show ();}}};

Android earlier version projects such as 1.5) put in a later version environment such as 2.2) may encounter the above error, the solution is as follows:

1. If you do not modify the android sdk version, use the project clean command to act on a project.

This processing method is only compatible with lower-version projects in the high version, and is not truly upgraded)

2. To modify the android sdk version, follow these steps:

1) modify the SDK

Select the project, build path --> configure build path ---> library to delete the referenced low-version SDK,

Add External JARs, select SDK of later version, OK, and save

2) modify the classpath File

This file may contain this item: <classpathentry kind = "lib" path = "Your specified High Version address"

Change her to <classpathentry kind = "con" path = "com. android. ide. eclipse. adt. ANDROID_FRAMEWORK"/>

3) Modify AndroidManifest. xml

In the AndroidManifest. xml file, add the <uses-sdk android: minSdkVersion = "3"> </uses-sdk>

4) It is important to modify default. properties)

It is useless before the last line of the file.) target = android-3 should be set to target = android-8 and saved.

Let's take a look at your project and the new android 2.2 project structure.

After you edit default. properties, the gen directory is generally automatically created. If no gen directory exists, you can also create it manually.

When installing android sdk:

-= Warning! =-A folder failed to be renamed or moved. on Windows this typically means that a program Is using that Folder (for example Windows Explorer or your anti-virus software .) please momentarily deactivate your anti-virus software. please also close any running programs that may be accessing the directory 'C: \ android-sdk-windows/too! S '. When ready, press YES to try again.

Cause and solution:

1. Copy the tools directory

Is a new directory named tools-copy. In this case, the android-sdk-windows directory contains two directories: tools and tools-copy.

2. run android. bat as an administrator in the tools-copy directory, so that you can update all normally.

3. Run the SDK Manager.exe again. Solve the problem!

Debugging:

[17:46:27-IpsosAutoAndroid] Failed to install IpsosAutoAndroid.apk on device '? ': Timeout

[17:46:27-IpsosAutoAndroid] Launch canceled!

Cause and solution:

When debugging a real machine, if the connection is too long and no response is returned, a timeout occurs.

1. Set the timeout time of ddms in window-prensent...-android. This is the most effective and concise.

2. delete the apk in android to ensure the speed. However, after a try, the real machine seems to be "smart" and there is also a timeout.

3. Cleaning the project (Project-> Clean). If it doesn't work, restart eclipse or android. It is depressing that it can be run for the first time after restart. The second time it starts to slow down, that is, the timeout occurs.

4. Close eclipse and restart it. OK.

Download the corresponding SDK Sources and put it in the \ android-sdk-windows \ sources directory!
