data not passing when running doInBackground method within for loop

I have some pics to upload to the ftp server and I am using Asynctask for it.The images need to be sent to multiple host so I am using a for loop.The data to be passed is very well being fetched by the constructor but the doInBackground method is not running which was earlier running very well without the for loop and the additional data apart from the String filePathName that I am trying to pass in now in doInBackground.please help me
class uploadTask extends AsyncTask<String, Void, String> {
public uploadTask(String filePathName,String host_2,String user_2,String pass_2)
{
filePath=filePathName;
host_1=host_2;
user_1=user_2;

You're trying to perform a UI command on a background thread (Toast). This is causing your background tasks to fail early. Since your background tasks catch their own errors, they fail silently.
#Override
protected String doInBackground(String... params) {
try {
// you can't Toast on a background thread, this should throw an exception
Toast.makeText(getBaseContext(),"Entered Do in Background Method to upload",Toast.LENGTH_SHORT).show();
...
}catch (Exception e){
// your Toast exception is getting caught silently here
String t="Failure : " + e.getLocalizedMessage();
return t;
}
}
By the way, the try/catch on everything is not a good practice. You end up with a ton of silent failures leaving you scratching your head and asking why things aren't working.

Google Fit Session title not "sticking"

My Referee watch creates a Google Fit Session using the following code:
private void insertFitSession(final Game currentGame, final Period period,
final long periodStartTime, final long periodEndTime) {
//add the detailed Sensor data (using History API) if available
boolean activityWasInserted = false;
if (!RefWatchUtil.isRefWatchFree()) {
//If there are speeds then we will insert an activity
//4.5.09: Unfortunately mFitnessDataSets[] can have leftover data from a period where you did track fitness
//So we had to replace with period-by-period dataSets
activityWasInserted = (period.getFitnessDataSet(SPEED_LISTENER_IDX) != null)
&& !period.getFitnessDataSet(SPEED_LISTENER_IDX).isEmpty();
}
//create a Session in Google Fit for the period that just completed
//(this happens even for Free)
try {
String sessionBaseName = currentGame.getTitle();
if (sessionBaseName.isEmpty()) sessionBaseName = currentGame.getLocation();
if (sessionBaseName.isEmpty()) sessionBaseName = RefWatchUtil.timeMillisToDefaultShortDateTime(currentGame.getStartTimeMillis());
final String sessionName = sessionBaseName + ": " + String.format(getResources().getString(R.string.fitness_period_label), period.getPeriodNum());
final Session.Builder fitnessSessionBuilder = new Session.Builder();
fitnessSessionBuilder
.setName(sessionName)
.setIdentifier(sessionName)
.setDescription(mCurrentGame.getDescription())
.setStartTime(periodStartTime, TimeUnit.MILLISECONDS)
.setEndTime(periodEndTime, TimeUnit.MILLISECONDS);
//If we're Free, then we don't have real fitness session data and just guess at Jogging
// (also if we have no Activity data in Pro)
if (RefWatchUtil.isRefWatchFree() || !activityWasInserted) {
fitnessSessionBuilder.setActivity(FitnessActivities.RUNNING_JOGGING);
}
final Session fitSession = fitnessSessionBuilder.build();
SessionInsertRequest insertRequest = new SessionInsertRequest.Builder()
.setSession(fitSession)
.build();
Fitness.SessionsApi.insertSession(mFitnessApiClient, insertRequest)
.setResultCallback(new ResultCallback<Status>() {
#Override
public void onResult(#NonNull Status status) {
if (status.isSuccess()) {
Log.d(TAG, "Successfully inserted Session " + sessionName);
} else {
Log.d(TAG, "There was a problem inserting the session " + sessionName
+ ": " + status.getStatusCode() + " " + status.getStatusMessage());
}
}
});
} catch (RuntimeException e){
Log.e(TAG, "There was a runtime exception inserting the session: " + e.getLocalizedMessage());
}
}
Note the sessionName defaults to either Title, Location, or Time appended with the current Period. This has been working great.
Recently (last month or so?) the Fit session is correctly inserted (I can track it in the log) but the Name doesn't stick. Instead I get "25 min running" for some, but not all, of them.
Has anybody else experienced this type of override by Fit?

Java InputSream hascode is different each time even when the request is same

I have a query not particular to UniversalImageLoader but because i am trying to use the content stream to load the image i am facing following issue.
I am using input stream "stream://" to be able to use ImageLoader. Everything is working fine except that the hashcode of the input stream for the same request is generated differently and hence forces the imageloader to download the image again from the network instead of the disk.
What should i do to fix it.
PS: I tried to follow the answer from here
The code to get InputStream is (The UtilityMethod is noting just an async task):
public void displayContentImage(final String fileId, final ImageView imageView) {
UtilityMethods.startMyTask(new AsyncTask<Object, Void, InputStream>() {
#Override
protected InputStream doInBackground(Object... params) {
CMServiceGateway cmServiceGateway = new CMServiceGateway();
final InputStream inputStream = cmServiceGateway.GetContentAsStream(fileId);
if (inputStream != null) {
//String imageId = "stream://" + inputStream.hashCode();
//Log.d("ImageId :: 1 ::", "file id : " + fileId + "hashcode: " + imageId);
//String imageId2 = "stream://" + cmServiceGateway.GetContentAsStream(fileId).hashCode();
//Log.d("ImageId :: 2 ::", "file id : " + fileId + "hashcode: " + imageId2);
return inputStream;
}
return null;
}
#Override
protected void onPostExecute(InputStream inputStream) {
if (inputStream != null) {
displayImage(inputStream, imageView);
}
}
});
}

The basic problem of hash code equal like the sample above where you will find that the second log hash code is different than first log hash code even if the inputStream object used is same.
//String imageId = "stream://" + inputStream.hashCode();
//Log.d("ImageId :: 1 ::", "file id : " + fileId + "hashcode: " + imageId);
//String imageId2 = "stream://" + cmServiceGateway.GetContentAsStream(fileId).hashCode();
//Log.d("ImageId :: 2 ::", "file id : " + fileId + "hashcode: " + imageId2);
Although not answering the above question exactly but I am able to resolve this problem by not passing the hashcode to the universal image loader as id. Instead i passed the unique file Id's and it worked well now to display image from memory cache.

SVM model fails to load in Android Application

I have a problem with load() method in SVM module. For example if I run code:
try {
Uri uri = Uri.fromFile(new File("file:///android_asset/SVM_Bills.xml"));
mySvm.load(uri.getPath());
int in = mySvm.get_support_vector_count();
if (in != 0) {
Toast.makeText(context,"done loading : " + uri.getPath(), Toast.LENGTH_SHORT).show();
value = (int)mySvm.predict(matOfDescriptor);
}
else {
Toast.makeText(context,"error while loading : " + uri.getPath(), Toast.LENGTH_SHORT).show();
}
It give me the error toast message (i.e it goes to else part and show the toast message).
Of course SVM was previously trained.
Any help please?

Titanium Android : Facebook dialog image URL not properly formatted

I developing an Android application using Titanium Appcelerator. I had tried to Post text and Image via facebook feed dialog
.. But error while load my local image URL..
var fileimg = Titanium.Filesystem.getFile(backupDir.nativePath, "myimg.jpg");
var fb_data1 = {
description : "Some good text",
picture : fileimg.nativePath,
link : "www.googlee.com",
};
facebook_qfav.dialog("feed", fb_data1, showRequestResult);
function showRequestResult(e) {
var s = '';
if (e.success) {
s = "SUCCESS";
if (e.result) {
s += "; " + e.result;
}
if (e.data) {
s += "; " + e.data;
}
if (!e.result && !e.data) {
s = '"success",but no data from FB.I am guessing you cancelled the dialog.';
}
} else if (e.cancelled) {
s = "CANCELLED";
} else {
s = "FAILED ";
if (e.error) {
s += "; " + e.error;
alert("facebook Share " + s);
}
}
}
ERROR: "Image URL not properly formatted"
File path will be like this: file:///storage/sdcard0/myimg.jpg
But if i pass the remote URL to the picture property , the image is shown in the dialog...
what happens to the local URL..?

I think the only issue is that nativepath has capital P in it. so, its : nativePath
so instead of picture : fileimg.nativepath, It Should be picture : fileimg.nativePath,
Documentation.
Hope it helps.
