Error loading photo - java

Good morning!
I am new to this forum.
I'm making an app for Android.
I have a photo gallery that I see is within a GridView.
Some photos charging me with no problems, while others give me this error:
ThreadPoolExecutor.runWorker (ThreadPoolExecutor $ Worker)
I also tried to change the format of those photos but nothing.
The photos are all taken from the same site.
I think the problem is in particular images.
This is the vector where there are several url of the photo
public final static String[] images = new String[]{"link1.jpg", "link2.jpg", ...};
I need help because I do not know how to solve this problem.

Convert Android view to PDF of A4 size

I have an android resume building application. I want to generate a PDF of size A4 from my view. Here's how my layout looks like - At the top I have a Top App Bar, and the whole view in encapsulated in drawer. The main part which contains user's details is encapsulated in nestedScrollView, which contains multiple LinearLayout and TextView. In this screenshot below, I have populated it with mock data, but in actuality, I am fetching data from the Firebase Realtime Database and displaying it on the UI.
I tried to understand iTextPdf solution and multiple question of similar type that has been asked here, but I couldn't find something solid. Please help me out, it would be of great help.
Also, please don't close this question by giving a reason that the question doesn't contain any code. It doesn't because I don't have any. I am trying to solve this problem from scratch. I have tried to describe my problem as much as I could.
try this:
create a WebView and copy the text of your edittext in it:
webview.loadData(youredittext.gettext().tostring, "text/html", "UTF-8");
and convert webview to pdf by below function:
private void createWebPrintJob(WebView webView) {
PrintManager printManager = (PrintManager) this
.getSystemService(Context.PRINT_SERVICE);
PrintDocumentAdapter printAdapter =
webView.createPrintDocumentAdapter();
String jobName = getString(R.string.app_name) + " Print Test";
if (printManager != null) {
printManager.print(jobName, printAdapter,
new PrintAttributes.Builder().build());
}
}
after that user can select page size for example A4
There are a lot of libraries that convert layouts to PDF, but let's opt for popular one so we could find answers if we're stuck.
The libraries I listed works like so : They take screenshot of your layout as bitmap image and convert it to pdf.
- 1st solution: iTextPDF https://github.com/itext/itext7 (New Version).
check this detailed tutorial which treates also the case of taking screenshot of a scrollview https://www.codeproject.com/Articles/989236/How-to-Convert-Android-View-to-PDF-2
and this stackoverflow answer https://stackoverflow.com/a/29731275/12802591
- 2nd solution: PdfMyXML library https://github.com/HendrixString/Android-PdfMyXml just follow the steps in the documentation.
They may be other solutions, but these are the popular ones.
Let Me know if it works for you and also if you're stuck. Thank you!

YoutubeThumbnailLoader taking too long to show a thumbnail?

Relevant code:
YouTubeThumbnailView first_video = (YouTubeThumbnailView) findViewById(R.id.main_video);
first_video.initialize(Config.YOUTUBE_API, new YouTubeThumbnailView.OnInitializedListener() {
#Override
public void onInitializationSuccess(YouTubeThumbnailView youTubeThumbnailView, YouTubeThumbnailLoader youTubeThumbnailLoader) {
final String video = getResources().getString(R.string.principal_funcoes);
youTubeThumbnailLoader.setVideo(video);
}
The time it takes for the method 'youTubeThumbnailLoader.setVideo(String s)" to work is absurd.
It takes 30+ seconds for a thumbnail to show up, with full cabled connection (100mbps).
It's definitely impossible for a user to wait more than 2 seconds for the thumbnail to show up, and have a completely blank screen while he waits for that to happen.
What can I do to load the video thumbnail any faster, or at least make YouTubeThumbnailView show a loading image while it fetches the thumbnail?
You can use direct youtube api urls for getting youtube thumbnails and they are way to faster too. here are urls you can try.
Start:-- It is only give you default size thumbnails.
https://ytimg.googleusercontent.com/vi/<insert-youtube-video-id-here>/default.jpg
For the high quality version of the thumbnail use a url similar to this:
https://ytimg.googleusercontent.com/vi/<insert-youtube-video-id-here>/hqdefault.jpg
There is also a medium quality version of the thumbnail, using a url similar to the HQ:
https://ytimg.googleusercontent.com/vi/<insert-youtube-video-id-here>/mqdefault.jpg
For the standard definition version of the thumbnail, use a url similar to this:
https://ytimg.googleusercontent.com/vi/<insert-youtube-video-id-here>/sddefault.jpg
For the maximum resolution version of the thumbnail use a url similar to this:
https://ytimg.googleusercontent.com/vi/<insert-youtube-video-id-here>/maxresdefault.jpg
It helps me to develop youtube application, Hope it also help you.

Facebook4j post picture with caption text

I'm new to Facebook4j and I want to sync my blog with Facebook And Twitter? The main idea is, everytime a new post is publised, a picture is simultaneously posted on social media, with an image and a caption (containing a link).
I've used this snippet for Facebook4, but it does not seem to be working. Picture is posted, but no caption is added to it !!
Media media = new Media(notificationPicture);
photoUpdate = new PhotoUpdate(media);
photoUpdate.setMessage(notificationCaption);
facebook.postPhoto(media);
Could you please tell what's wrong or missing with this snippet ?
Thank you very much.

Most efficient way to load a lot of images from URL Android

I'm making this netflix style app in which images are loaded into different categories. Let's say Dog videos (has 15 images), Cat videos (15 images), etc... All the images are loaded from a URL, it kind of takes a while for all to load. I was wondering if there was anything I could do to speed up the process? Or maybe show an empty container then fill it as the images load (that would be cool).
This is what I have done:
I have multiple async calls in one Activity, (1 async call per category)
JSONTask1 dogTask = new JSONTask1();
JSONTask2 catTask = new JSONTask2();
JSONTask3 pigTask = new JSONTask3();
JSONTask4 horseTask = new JSONTask4();
dogTask.execute("");
catTask.execute("");
pigTask.execute("");
horseTask.execute("");
I have all of those in a row in my actual code. Thanks.
I would use the "proxy pattern". Basically, you need to create a class that contains the minimal informations required for the display. In which, you have a preview image.
When ever you load everything you start by showing the preview content, ie : a loading gif for everypicture with the title of the movie or whatever. and basically the proxy would have a "loadImage" method that would make an ajax call or async call and the photos would load one by one. Plus, to make the loading easier, make sure the photos are not oversized.
You can see Picasso answers , in picasso i suggest you this way :
Picasso.with(getApplicationContext()).load("your url").placeholder(R.drawable.your_place_holder).error(R.drawable.showing_when_error_occured)
.into(imageView, new Callback() {
#Override
public void onSuccess() {
}
#Override
public void onError() {
}
});
Also another suggestion from me : convert your thumb images to base64 format in backend, then firstly retrieve your thumbs and show them. Then start an async task and change images when successfull.
Like whatsapp. In whatsapp you have thumb images they have so low resolution and super fast. When you click image if you have internet connection they load actual thumb images, and click again they load larger image.
Picasso website :http://square.github.io/picasso/
Load them asynchronously with Picasso, you can even show a placeholder image until the real one is loaded

Sharing animated GIF to Twitter makes it static (iOS)

So I'm using LibGDX and RoboVM to convert my Android project to an iOS app. I'm trying to share an animated GIF that the user has just created and saved to their device, here's what I have so far:
public void shareGif(String path)
{
NSData data = new NSData(Gdx.files.absolute(path).readBytes());
NSArray<NSData> nsObjectsToShare = new NSArray<NSData>(data);
ArrayList<String> excludedActivities = new ArrayList<String>();
excludedActivities.add(UIActivityType.Print());
excludedActivities.add(UIActivityType.AddToReadingList());
excludedActivities.add(UIActivityType.PostToVimeo());
excludedActivities.add(UIActivityType.PostToTencentWeibo());
UIActivityViewController share = new UIActivityViewController(nsObjectsToShare, null);
share.setExcludedActivityTypes(excludedActivities);
((IOSApplication)Gdx.app).getUIViewController().presentViewController(share, true, null);
}
Now, this does work. It successfully opens the share window and sends an animated GIF via Mail and Message. Twitter, however, only seems to share a static image (it appears to actually be a JPG when I examine it on my Twitter timeline).
Anyone have any ideas how I can get Twitter to share the ANIMATED version of the GIF? I know I'm not using Objective-C like with typical iOS apps but I'm hoping you can still make out what's going on in the above code.
Was apparently fixed in iOS 8. Just updated my device and it works now. Cool.
