I am moving my android application from asmack-android library to Smack 4.1.4. I have some PacketExtensions in the asmack version of Smack, which uses PacketExtension and Pa
Finally figured it out.... Here is the solution for it...
import org.jivesoftware.smack.packet.DefaultExtensionElement;
public class IM_FileSharing_Extension extends DefaultExtensionElement implements
IM_Commons_Extension_FileSharing {
private String fileUrl;
private String fileType;
private String base64preview;
private String fileId;
private String fileSize;
public IM_FileSharing_Extension(String fileUrl, String fileType,
String base64preview, String fileId, String fileSize) {
super(FILE_TAG, XMLNS);
this.fileUrl = fileUrl;
this.fileType = fileType;
this.base64preview = base64preview;
this.fileId = fileId;
this.fileSize = fileSize;
}
@Override
public String toXML() {
StringBuilder sb = new StringBuilder("<" + FILE_TAG + " xmlns=\""
+ XMLNS + "\" ");
sb.append(FILE_URL + "=\"" + fileUrl + "\" ");
sb.append(FILE_ID + "=\"" + fileId + "\" ");
sb.append(FILE_TYPE + "=\"" + fileType + "\" ");
sb.append(FILE_SIZE + "=\"" + fileSize + "\">");
sb.append("<" + FILE_PREVIEW_TAG + ">" + base64preview + ""
+ FILE_PREVIEW_TAG + ">");
sb.append("" + FILE_TAG + ">");
return sb.toString();
}
public String getFileUrl() {
return fileUrl;
}
public void setFileUrl(String fileUrl) {
this.fileUrl = fileUrl;
}
public String getBase64preview() {
return base64preview;
}
public void setBase64preview(String base64preview) {
this.base64preview = base64preview;
}
public String getFileId() {
return fileId;
}
public void setFileId(String fileId) {
this.fileId = fileId;
}
public String getFileType() {
return fileType;
}
public void setFileType(String fileType) {
this.fileType = fileType;
}
public String getFileSize() {
return fileSize;
}
public void setFileSize(String fileSize) {
this.fileSize = fileSize;
}
}
Provider for the above extension is as follows...
import java.io.IOException;
import org.jivesoftware.smack.SmackException;
import org.jivesoftware.smack.provider.ExtensionElementProvider;
import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlPullParserException;
import android.util.Log;
public class IM_FileSharingExtension_Provider extends
ExtensionElementProvider implements
IM_Commons_Extension_FileSharing {
static final String TAG = "file_extension";
@Override
public IM_FileSharing_Extension parse(XmlPullParser parser, int initialDepth)
throws XmlPullParserException, IOException, SmackException {
IM_FileSharing_Extension fileExtension = null;
boolean stop = false;
String n = null;
int evtType;
String fileUrl = null;
String fileType = null;
String fileId = null;
String fileSize = null;
while (!stop) {
evtType = parser.getEventType();
n = parser.getName();
Log.d(TAG, "n:" + n + " evt:" + evtType);
switch (evtType) {
case XmlPullParser.START_TAG:
if (FILE_TAG.equals(n)) {
fileUrl = parser.getAttributeValue("", FILE_URL);
fileType = parser.getAttributeValue("", FILE_TYPE);
fileId = parser.getAttributeValue("", FILE_ID);
fileSize = parser.getAttributeValue("", FILE_SIZE);
evtType = parser.next();
}
if (FILE_PREVIEW_TAG.equals(parser.getName())) {
String basePreview = parser.nextText();
fileExtension = new IM_FileSharing_Extension(fileUrl,
fileType, basePreview, fileId, fileSize);
}
evtType = parser.next();
break;
case XmlPullParser.END_TAG:
if (parser.getName().equals(FILE_TAG)) {
return fileExtension;
}
evtType = parser.next();
}
}
return null;
}
}
And should be added in Provider manager as following....
ProviderManager.addExtensionProvider(
IM_Commons_Extension_FileSharing.FILE_TAG,
IM_Commons_Extension_FileSharing.XMLNS,
new IM_FileSharingExtension_Provider());
