StickerView | Imitation Weibo sticker effect

i want to put sticker view completely inside the image view( it should not go out of image boundary)

image view is uploaded by user so it cannot be a fixed size.I can do adjustments on sticker size if needed current sticker size (540x670)

In my app i'm executing two for loops however those for loops need to scheduled in a order here is the use case:

There are two for loops : 1- ImageStickerslist 2-TextStickerslist

What i want to do is after imagestickerslist if properly finised only then textstickerslist will be executed.

Here imagesticker list consists of url path which is used to load images from glide however if those images are of high resolution it eventually makes the thread continue even if the image is not yet loaded from url. To solve this tried adding blocking calls to glide on ready and full method but it won't prove to be of any help. I'm very confused how blocking calls work any help into this will be really appreciated.

Here's my code where for loops are executed:

In our app, we have a canvas. The canvas could contain Stickers, Images, Texts, etc. We have a protocol CanvasItem that implement the common properties between these items:

In my app users are able to create images and then use them as stickers in iMessages.

My problem is that I can't display created images that are stored in the Documents Directory.

My issue is very similar to this question - SO Question but in my case the solution stated there didn't help.

Here's my code for fetching images:

give Exception:

I have these lines of code in which if I stop on the X to delete an image I delete it. The problem is that if I have one or more of the same type of image, removing one of them, it also erases all the other identical ones. I think my problem is in calling the "forEach". What should I use?

While if the images are different, I delete correctly the single "sticker".

It irritates me because I have to see yellow line in my code each time I open class.

I have also added @SuppressLint("ClickableViewAccessibility") above onTouch.

My MultiTouchListener class :

I am using wuapnjie/StickerView library in my app and one of the function getCurrentSticker in StickerView class is returning null object reference when I called the method in onCreate method, but working perfectly when called from any onClick method. Any of your expertise will be very helpful. Thanks.

When I try to run the code in separate thread within runOnUiThread sometimes it is working and sometimes not. How come some code would work sometime and not the other time. I am very confused. Below is the piece of code which works in onClick method and not in onCreate method.

When I call addStickerNow in below code from onCreate, it returns null value. In onClick method it is returning actual value.

I am getting some issues related to APNG file, APNG file animation working perfect if i put APNG files in resource bundle , But when i have download same APNG file from assets server and saving APNG file into resource directory and then load using MSSticker like this way. after loading it showing only first frame.if anyone wanna try to check APNG file please have a look to this.
