I have an old Samung phone to be used as a toy. After restoring back to factory image and power on, I was stuck at the activate service screen. Unfortunately, the four corner magic touch did not work.

The javax.xml.crypto and javax.xml.crypto.dsig packages are not available in Android (as of version 2.3). Therefore, standard Java API does not work. But you can use the Apache Santuario library to do that. Here are the steps: Download the xml security source distribution (curently version 1.4.4). Build with ant. Create your own library jar (only the apache classes, no javax):
jar -cf xmlsec-1.4.4.jar -C build/classes orgCopy xmlsec-1.4.4.jar to the libs directory of your Android project. Here's the Java code:
import java.io.*; import javax.xml.parsers.*; ...

There's no difference between a Java HTTP client and a Java HTTPS client. Ignore JavaWorld Java Tip 96 , it's way too old. The following code gets an HTTP page as well as an HTTPS page.
import java.io.*; import java.net.*; pub...There's one catch . If you are using the code on a test server with a self-signed certificate, it fails. In that case, I would suggest that you download the certificate from the server and import it to your keystore as a trusted key. You may also need to add a subject alternative name to the certificate if the host name does not match the certificate. You may also choose to use a custom TrustManager and HostnameVerifier to ignore the certificate verification errors.

Parsing XML in Java is really simple:
import java.io.*; import javax.xml.parsers.Docu...The parser implementation details are hidden behind the JAXP API. In case you want to know which parser implementation is used, this is what the JavaDoc for DocumentBuilderFactory.newInstance says: Use the javax.xml.parsers.DocumentBuilderFactory system property. Use the properties file " lib/jaxp.properties " in the JRE directory. This configuration file is in standard java.util.Properties format and contains the fully qualified name of the implementation class with the key being the system property defined above. The jaxp.properties file is read only once by the JAXP implementation and it's values are then cached for future use. If the file does not exist when the first attempt is made to read from it, no further attempts are made to...
