I want to bulk upload images parallel with Async task. Please suggest how can i use Multipart data to upload images like WhatsApp.
For every file make new instance of AsyncTask and execute it.
Use this:
void startMyTask(AsyncTask asyncTask) {
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)
asyncTask.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, params);
else
asyncTask.execute(params);
}
Alternatively, you can use this library for easy implementation.

I've a requirement to download a file from S3 based on a message content. In other words, the file to download is previously unknown, I've to search and find it at runtime. S3StreamingMessageSource doesn't seem to be a good fit because:
It relies on polling where as I need to wait for the message.
I can't find any way to create a S3StreamingMessageSource dynamically in the middle of a flow. gateway(IntegrationFlow) looks interesting but what I need is a gateway(Function<Message<?>, IntegrationFlow>) that doesn't exist.
Another candidate is S3MessageHandler but it has no support for listing files which I need for finding the desired file.
I can implement my own message handler using AWS API directly, just wondering if I'm missing something, because this doesn't seem like an unusual requirement. After all, not every app just sits there and keeps polling S3 for new files.
There is S3RemoteFileTemplate with the list() function which you can use in the handle(). Then split() result and call S3MessageHandler for each remote file to download.
Although the last one has functionality to download the whole remote dir.
For anyone coming across this question, this is what I did. The trick is to:
Set filters later, not at construction time. Note that there is no addFilters or getFilters method, so filters can only be set once, and can't be added later. #artem-bilan, this is inconvenient.
Call S3StreamingMessageSource.receive manually.
.handle(String.class, (fileName, h) -> {
if (messageSource instanceof S3StreamingMessageSource) {
S3StreamingMessageSource s3StreamingMessageSource = (S3StreamingMessageSource) messageSource;
ChainFileListFilter<S3ObjectSummary> chainFileListFilter = new ChainFileListFilter<>();
chainFileListFilter.addFilters(
new S3SimplePatternFileListFilter("**/*/*.json.gz"),
new S3PersistentAcceptOnceFileListFilter(metadataStore, ""),
new S3FileListFilter(fileName)
);
s3StreamingMessageSource.setFilter(chainFileListFilter);
return s3StreamingMessageSource.receive();
}
log.warn("Expected: {} but got: {}.",
S3StreamingMessageSource.class.getName(), messageSource.getClass().getName());
return messageSource.receive();
}, spec -> spec
.requiresReply(false) // in case all messages got filtered out
)
I'm currently using MvvmCross DownloadCache -- and it's working alright -- especially nice when I just need to drop in an Image URL and it automagically downloads / caches the image and serves up a UIImage.
I was hoping to leverage the code for one other use case -- which is I'd like to grab source images from URL's and cache the files on the local file system, but what I really want for this other use case is the image path on the local file system instead of the UIImage itself.
What would help me most if I could get an example of how I might accomplish that. Is it possible to make that happen in a PCL, or does it need to go into the platform specific code?
Thanks -- that works, but just in case anyone else is following along, I wanted to document how I got the Mvx.Resolve<IMvxFileDownloadCache>() to work. In my setup.cs (in the touch project), I had:
protected override void InitializeLastChance ()
{
Cirrious.MvvmCross.Plugins.DownloadCache.PluginLoader.Instance.EnsureLoaded();
Cirrious.MvvmCross.Plugins.File.PluginLoader.Instance.EnsureLoaded();
Cirrious.MvvmCross.Plugins.Json.PluginLoader.Instance.EnsureLoaded();
...
}
But that wasn't enough, because nothing actually registers IMvxFileDownloadCache inside the DownloadCache plugin (which I was expecting, but it's just not the case).
So then I tried adding this line here:
Mvx.LazyConstructAndRegisterSingleton<IMvxFileDownloadCache, MvxFileDownloadCache>();
But that failed because MvxFileDownloadCache constructor takes a few arguments. So I ended up with this:
protected override void InitializeLastChance ()
{
...
var configuration = MvxDownloadCacheConfiguration.Default;
var fileDownloadCache = new MvxFileDownloadCache(
configuration.CacheName,
configuration.CacheFolderPath,
configuration.MaxFiles,
configuration.MaxFileAge);
Mvx.RegisterSingleton<IMvxFileDownloadCache>(fileDownloadCache);
...
}
And the resolve works okay now.
Question:
I do wonder what happens if two MvxFileDownloadCache objects that are configured in exactly the same way will cause issues by stepping on each other. I could avoid that question by changing the cache name on the one I'm constructing by hand, but I do want it to be a single cache (the assets will be the same).
If you look at the source for the plugin, you'll find https://github.com/MvvmCross/MvvmCross/blob/3.2/Plugins/Cirrious/DownloadCache/Cirrious.MvvmCross.Plugins.DownloadCache/IMvxFileDownloadCache.cs - that will give you a local file path for a cached file:
public interface IMvxFileDownloadCache
{
void RequestLocalFilePath(string httpSource, Action<string> success, Action<Exception> error);
}
You can get hold of a service implementing this interface using Mvx.Resolve<IMvxFileDownloadCache>()
To then convert that into a system-wide file path, try NativePath in https://github.com/MvvmCross/MvvmCross/blob/3.2/Plugins/Cirrious/File/Cirrious.MvvmCross.Plugins.File/IMvxFileStore.cs#L27
I am trying to get videos from youtube in two different ways
a) First using youtube-google-api client library following the guidelines and sample code from here https://developers.google.com/youtube/v3/code_samples/java#search_by_keyword
Nevertheless, since I am implementing in a mavenized project Ihave difficulty in finding the dependency for 'com.google.api.services.samples.youtube.cmdline.Auth" which is required for the following block of code:
try {
youtube = new YouTube.Builder(Auth.HTTP_TRANSPORT, Auth.JSON_FACTORY, new HttpRequestInitializer() {
public void initialize(HttpRequest request) throws IOException {
}
}).setApplicationName("youtube-cmdline-search-sample").build();
b)Second I simply send a GET request to YouTube like this:
https://www.googleapis.com/youtube/v3/search?part=snippet&q=madonna&type=video&key={API_KEY}
but I am able to receive only 5 results, although I've read in several Stackoverflow related questions that I can receive up to 50 videos.This is not feasible even if I set the "max-results" parameter.
Could anyone help me to deal with these issues? Thank you in advance.
In your second way Write maxResults=50 as a parameter instead of max-results=50.
Use YouTube Data Api v3 api explorer to understand parameters very well.

I am using the watcher service and it works great. I need to only watch for files with a certain extension, e.g. .xml. How can I implement this?
Thanks.
It appears that there is no built-in file extension filter (like there is using the old java.io.FileFilter interface). I solved this same issue by adding an "if" statement in my processing code like so:
// Watcher gives key and you get event...
WatchEvent<Path> ev = (WatchEvent<Path>) event;
Path file = dir.resolve(ev.context());
if (isCorrectFileType(file)) {
// Do you processing here.
}
And the simple check:
private boolean isCorrectFileType(Path file) {
return (file.toString().endsWith(".xml"));
}
I have code such that:
[CodedUITest]
public class CodedUITest1
{
[TestMethod]
public void CodedUITestMethod1( )
{
using(var dlg = new MyWinForm( ))
{
dlg.Show();
System.Threading.Thread.Sleep(2000);
this.UIMap.AssertMethod1( );
this.UIMap.RecordedMethod1( );
this.UIMap.AssertMethod2( );
}
}
}
The code was running fine when I manually launched the app(before invoking the test) without the using clause to directly create the control.
I'd like to just use a reference to create an instance of the control and go from there instead of relying on trying to determine a path to the executable and opening it. The app just gets stuck with a ContextSwitchDeadlock.
Is there a way to do coded-Ui tests without doing a process launch? (using the reference and creating the control in the test code) or is there something wrong with the way I'm trying to do it?
It might be possible if you invoke the coded ui test portions (this.UIMap...) on a separate thread. But the way you have it now, they are both on the same thread, so you are going to get deadlocked.
