How to put multiple assets in a data event for Android Development

I am trying to make an app that sends files from my Android Watch to my Android Phone.
The problem I have is that if I record and save multiple files and send all of them at the same time, I do not get all the files back on the phone side. I only receive one file.
The code for sending the file is as follows. This code is implemented on the Watch side.:
public void sendData(View v){
String fname = "_Activity.bin";
int FileCounterCopy = FileCounter;
if(mGoogleApiClient.isConnected()){
for (int i = 0; i < FileCounterCopy ; i++){
String FileName = String.valueOf(i) + fname;
File dataFile = new File(Environment.getExternalStorageDirectory(), FileName);
Log.i("Path", Environment.getExternalStorageDirectory().toString());
Log.i("file", dataFile.toString());
Asset dataAsset = createAssetfromBin(dataFile);
sensorData = PutDataMapRequest.create(SENSOR_DATA_PATH);
sensorData.getDataMap().putAsset("File", dataAsset);
PutDataRequest request = sensorData.asPutDataRequest();
Wearable.DataApi.putDataItem(mGoogleApiClient, request).setResultCallback(new ResultCallback<DataApi.DataItemResult>() {
#Override
public void onResult(DataApi.DataItemResult dataItemResult) {
Log.e("SENDING IMAGE WAS SUCCESSFUL: ", String.valueOf(dataItemResult.getStatus().isSuccess()));
}
});
boolean deleted = dataFile.delete();
Log.i("Deleted", String.valueOf(deleted));
FileCounter--;
}
mTextView.setText(String.valueOf(FileCounter));
Return();
}
else {
Log.d("Not", "Connecteddddddddd");
}
}
The code for receiving the files is as follows and is implemented on the phone side.
#Override
public void onDataChanged(DataEventBuffer dataEvents) {
Counter++;
final List<DataEvent> events = FreezableUtils.freezeIterable(dataEvents);
dataEvents.close();
Log.e("List Size: ", String.valueOf(events.size()));
for (DataEvent event : events) {
if (event.getType() == DataEvent.TYPE_CHANGED) {
Log.v("Data is changed", "========================");
String path = event.getDataItem().getUri().getPath();
if (SENSOR_DATA_PATH.equals(path)) {
DataMapItem dataMapItem = DataMapItem.fromDataItem(event.getDataItem());
fileAsset = dataMapItem.getDataMap().getAsset("File");
myRunnable = createRunnable();
if (checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED)
new Thread(myRunnable).start();
}
}
}
status.setText("Received" + " File_"+ String.valueOf(Counter) );
}
Right before the for loop, I check the size of the event and it only shows a size of 1, no matter how many files I save.
I am stuck on how to implement this (tbh I used code from youtube video/online resources so I am not 100% sure on how some of the api works).
Thanks in advance!

You're putting all of the files at the same path, with nothing to differentiate them - so each one you put in overwrites the previous ones. The Data API works much like a filesystem in this regard.
In your sendData method, you need code something like this:
sensorData = PutDataMapRequest.create(SENSOR_DATA_PATH + '/' + dataFile.toString());
And then in onDataChanged, either only check the path prefix...
if (path.startsWith(SENSOR_DATA_PATH)) {
...or, preferably, put the value of SENSOR_DATA_PATH in your manifest declaration as an android:pathPrefix element in the intent-filter of your data receiver. You can then remove the path check from your Java code completely. Docs for that are here: https://developers.google.com/android/reference/com/google/android/gms/wearable/WearableListenerService
One other thing: it's good practice to clear stuff like these files out of the Data API when you're done using them, so that they're not taking up space there.

Open Office 1.1.4 Export to PDF with background images using java

I have a problem that needs solving where we use OpenOffice 1.1.4 templated reports and programmatically export them to PDF.
The team who create the templates have recently changed the header image and some images in a table to background images (before they were just inserted) since this change the current program is not creating the PDFs with the images. We can export from OpenOffice manually and the images are included. Can anyone help with a change I may need to make to get these background images included please?
The current code:
private void print(XInterface xComponent,
PrintRequestDTO printReq, File sourceFile,
Vector<String> pages) throws java.lang.Exception {
String pageRange;
// XXX create the PDF via OOo export facility
com.sun.star.frame.XStorable pdfCreator = (com.sun.star.frame.XStorable) UnoRuntime
.queryInterface(
com.sun.star.frame.XStorable.class,
xComponent);
PropertyValue[] outputOpts = new PropertyValue[2];
outputOpts[0] = new PropertyValue();
outputOpts[0].Name = "CompressionMode";
outputOpts[0].Value = "1"; // XXX Change this perhaps?
outputOpts[1] = new PropertyValue();
outputOpts[1].Name = "PageRange";
if (printReq.getPageRange() == null) {
pageRange = "1-";
}
else {
if (printReq.getPageRange().length() > 0) {
pageRange = printReq.getPageRange();
}
else {
pageRange = "1-";
}
}
log.debug("Print Instruction - page range = "
+ pageRange);
PropertyValue[] filterOpts = new PropertyValue[3];
filterOpts[0] = new PropertyValue();
filterOpts[0].Name = "FilterName";
filterOpts[0].Value = "writer_pdf_Export"; // MS Word 97
filterOpts[1] = new PropertyValue();
filterOpts[1].Name = "Overwrite";
filterOpts[1].Value = new Boolean(true);
filterOpts[2] = new PropertyValue();
filterOpts[2].Name = "FilterData";
filterOpts[2].Value = outputOpts;
if (pages.size() == 0) { // ie no forced page breaks
// set page range
outputOpts[1].Value = pageRange;
filterOpts[2] = new PropertyValue();
filterOpts[2].Name = "FilterData";
filterOpts[2].Value = outputOpts;
File outputFile = new File(
sourceFile.getParent(),
printReq.getOutputFileName()
+ ".pdf");
StringBuffer sPDFUrl = new StringBuffer(
"file:///");
sPDFUrl.append(outputFile.getCanonicalPath()
.replace('\\', '/'));
log.debug("PDF file = " + sPDFUrl.toString());
if (pdfCreator != null) {
sleep();
pdfCreator.storeToURL(sPDFUrl.toString(),
filterOpts);
}
}
else if (pages.size() > 1) {
throw new PrintDocumentException(
"Only one forced split catered for currently");
}
else { // a forced split exists.
log.debug("Page break found in "
+ (String) pages.firstElement());
String[] newPageRanges = calculatePageRanges(
(String) pages.firstElement(), pageRange);
int rangeCount = newPageRanges.length;
for (int i = 0; i < rangeCount; i++) {
outputOpts[1].Value = newPageRanges[i];
log.debug("page range = " + newPageRanges[i]);
filterOpts[2] = new PropertyValue();
filterOpts[2].Name = "FilterData";
filterOpts[2].Value = outputOpts;
String fileExtension = (i == 0 && rangeCount > 1) ? "__Summary.pdf"
: ".pdf";
File outputFile = new File(
sourceFile.getParent(),
printReq.getOutputFileName()
+ fileExtension);
StringBuffer sPDFUrl = new StringBuffer(
"file:///");
sPDFUrl.append(outputFile.getCanonicalPath()
.replace('\\', '/'));
log.debug("PDF file = " + sPDFUrl.toString());
if (pdfCreator != null) {
log.debug("about to create the PDF file");
sleep();
pdfCreator.storeToURL(
sPDFUrl.toString(), filterOpts);
log.debug("done");
}
}
}
}
Thanks in advance.

Glad that suggestion of making the document visible helped. Since it has ALSO fixed the problem you have a timing/threading issue. I suspect you'll find that another dodgy option of doing a sleep before executing the save to PDF will also allow the images to appear. Neither of these solutions is good.
Most likley best fix is to upgrade to a newer version of Open Office (the API calls you have should still work). Another option would be to try to call the API to ask the document to refresh itself.

After finding the correct property I was able to open the file with the hidden property set to false, this meant when the file was exported to PDF it included the background images. Its a shame I could not find another solultion that kept the file hidden but at least its working.

Jacob Export Outlook Contact Pictures (Java, Jacob)

Good Morning,
I’am using Jacob 1.17 o read all my Outlook Contact Pictures and save them to an File. The Procedure works pretty fine for the first 199 Contatcs. After that the Dispatch.call fails and terminates with the following Exception:
Exception in thread "main" com.jacob.com.ComFailException: Invoke of: SaveAsFile
Source: Microsoft Outlook
Description: Cannot save the attachment. Cannot create file: ContactPicture.jpg.
Right-click the folder you want to create the file in, and then click Properties on
the shortcut menu to check your permissions for the folder.

at outlookStuff.ManageContactsOutlook.tmpTest(ManageContactsOutlook.java:217)
at mainPackage.Main.main(Main.java:32)
I’m really not sure way. I tested a different set of Contacts – same Error. Set all Objects to null to make shore that the Garbage Collector is involved but it doesn’t help.
The piece of Code which makes the trouble:
public void tmpTest(int intOutlookFolder, String strWorkingDir) {
Dispatch dipNamespace = this.axc.getProperty("Session").toDispatch();
Dispatch dipContactsFolder = Dispatch.call(dipNamespace, "GetDefaultFolder", (Object) new Integer(intOutlookFolder)).toDispatch();
Dispatch dipContactItems = Dispatch.get(dipContactsFolder, "items").toDispatch();
#SuppressWarnings("deprecation")
int count = Dispatch.call(dipContactItems, "Count").toInt();
for (int i=1; i<=count; i++) {
Dispatch dipContact;
dipContact = Dispatch.call(dipContactItems, "Item", new Integer(i)).toDispatch();
String strEntryID = Dispatch.get(dipContact, "EntryID").toString().trim();
//For Testing
Status.printStatusToConsole("Outlook Contact "+strEntryID+" loaded");
byte[] byteContactPicture = null;
String strPathToTmpPicture = null;
Dispatch dipAttachments = Dispatch.get(dipContact, "Attachments").toDispatch();
#SuppressWarnings("deprecation")
int countAttachements = Dispatch.call((Dispatch) dipAttachments, "Count").toInt();
for (int j=1; j<=countAttachements; j++) {
Dispatch currentAttachement;
currentAttachement = Dispatch.call(dipAttachments, "Item", new Integer(j)).toDispatch();
if (Dispatch.get(currentAttachement, "FileName").toString().equals("ContactPicture.jpg")) {
strPathToTmpPicture = strWorkingDir+strEntryID+".jpg";
//The Crashing Part
Dispatch.call(currentAttachement, "SaveAsFile", strPathToTmpPicture);
File tmpFile = new File(strPathToTmpPicture);
if (tmpFile.exists()) {
try {
byteContactPicture = org.apache.commons.io.FileUtils.readFileToByteArray(tmpFile);
} catch (IOException e) {
e.printStackTrace();
}
}
currentAttachement = null;
tmpFile = null;
}
currentAttachement = null;
}
dipAttachments = null;
}
dipContactItems = null;
dipContactsFolder = null;
dipNamespace = null;
}
May someone has an idea?
Thanks

Get the full path of a file at change set

I am searching for a .txt file that is located at change set.
Then I need to create locally over my pc the full path directory of this file.
For example if there a file called"test.txt" that it's located at:
Project1-->Folder1-->Folder2-->test.txt
Till now I have managed to search for this file.
Now I need to fetch the full directory and create similar one over my pc:
Result at my pc:
Folder1-->Folder2-->test.txt
That's what I did to search for the file within a changeset and retrieve it:
public IFileItem getTextFileFile(IChangeSet changeSet, ITeamRepository repository) throws TeamRepositoryException{
IVersionableManager vm = SCMPlatform.getWorkspaceManager(repository).versionableManager();
List changes = changeSet.changes();
IFileItem toReturn = null;
for(int i=0;i<changes.size();i++) {="" <br=""> Change change = (Change) changes.get(i);
IVersionableHandle after = change.afterState();
if( after != null && after instanceof IFileItemHandle) {
IFileItem fileItem = (IFileItem) vm.fetchCompleteState(after, null);
if(fileItem.getName().contains(".txt")) {
toReturn = fileItem;
break;
} else {
continue;
}
}
}
if(toReturn == null){
throw new TeamRepositoryException("Could not find the file");
}
return toReturn;
}
I use RTC:4
Win:XP
Thanks in advance.

I have the following IConfiguration that I fetched by the following:
IWorkspaceManager workspaceManager = SCMPlatform.getWorkspaceManager(repository);
IWorkspaceSearchCriteria wsSearchCriteria = WorkspaceSearchCriteria.FACTORY.newInstance();
wsSearchCriteria.setKind(IWorkspaceSearchCriteria.STREAMS);
wsSearchCriteria.setPartialOwnerNameIgnoreCase(projectAreaName);
List <iworkspacehandle> workspaceHandles = workspaceManager.findWorkspaces(wsSearchCriteria, Integer.MAX_VALUE, Application.getMonitor());　
IWorkspaceConnection workspaceConnection = workspaceManager.getWorkspaceConnection(workspaceHandles.get(0),Application.getMonitor());
IComponentHandle component = changeSet.getComponent();
IConfiguration configuration = workspaceConnection.configuration(component);
List lst = new ArrayList<string>();
lst=configuration.locateAncestors(lst,Application.getMonitor());
=========================================
Now to get the full path of the file item ,I made the following method I got from :
https://jazz.net/forum/questions/94927/how-do-i-find-moved-from-location-for-a-movedreparented-item-using-rtc-4-java-api
=========================================
private String getFullPath(List ancestor, ITeamRepository repository)
throws TeamRepositoryException {
String directoryPath = "";
for (Object ancestorObj : ancestor) {
IAncestorReport ancestorImpl = (IAncestorReport) ancestorObj;
for (Object nameItemPairObj : ancestorImpl.getNameItemPairs()) {
NameItemPairImpl nameItemPair = (NameItemPairImpl) nameItemPairObj;
Object item = SCMPlatform.getWorkspaceManager(repository)
.versionableManager()
.fetchCompleteState(nameItemPair.getItem(), null);
String pathName = "";
if (item instanceof IFolder) {
pathName = ((IFolder) item).getName();
}
else if (item instanceof IFileItem) {
pathName = ((IFileItem) item).getName();
}
if (!pathName.equals(""))
directoryPath = directoryPath + "\\" + pathName;
}
}
return directoryPath;
}
=========================================

Fastest/shortest way to the root folders?

I'm using Google Drive SDK v2 on Android to get the list of root folders. Currently I see these required steps - which seem to load forever. Is there no faster way?
I tried to use the search with the q= parameter but I don't get it to work (FileList vs. Files.List) - different API levels?
FileList files = drive.files().list().setQ("'root' in parents and mimeType='application/vnd.google-apps.folder' and trashed=false");
This is what I do currently:
About about = drive.about().get().execute();
if (about != null) {
ChildList childList = drive.children().list(about.getRootFolderId()).execute();
if (childList != null) {
List<ChildReference> listChildReference = childList.getItems();
for (ChildReference childReference : listChildReference) {
File file = drive.files().get(childReference.getId()).execute();
if (file != null) {
String fileExtension = file.getFileExtension();
String mimeType = file.getMimeType();
if (mimeType != null
&& mimeType.equals("application/vnd.google-apps.folder")
&& (fileExtension == null || fileExtension.equals(""))) {
Log.d(this.getClass().getName(), file.getTitle());
}
}
}
}
}
What's the fastest for an Android app?
Thanks in advance.

My personal opinion is avoid the Drive SDK and call the REST API directly. It's a fairly simple API, and the way the documentation is structured, you are forced to understand it anyway in order to use the SDK. You have the benefit that if something doesn't work, you can directly compare your app with what's happening on the wire and resolve any problems.

Found it:
#Override
protected ArrayList<File> doInBackground(final Void... voids) {
ArrayList<File> result = new ArrayList<File>();
Files.List request = null;
boolean ok = true;
do {
try {
request = drive
.files()
.list()
.setMaxResults(200)
.setQ("'root' in parents and mimeType='application/vnd.google-apps.folder' and trashed=false");
FileList files = request.execute();
result.addAll(files.getItems());
request.setPageToken(files.getNextPageToken());
} catch (IOException exception) {
ok = false;
}
} while (ok && request.getPageToken() != null && request.getPageToken().length() > 0);
return result;
}
