whatsapp

Background Similar to issues I've recently had with sharing/opening APK files ( here , here and here ) , I now have an issue of sending an image file (in assets, res/raw or even from a URL) to specific apps: WhatsApp and Viber. I need to be able to share an image file to all apps, especially popular ones such as WhatsApp and Viber. The problem Both WhatsApp and Viber have issues when I try to share the image files on Andorid 7.1.1 . On other apps, and on previous versions of Android, it worked fine. They either show a black screen (no image) or close themselves, on all of the test I've tried.

I need to send an image from my app with a text, I know how to send just an image or just a text, but I don't know how to combine both of them. Just an Image: let image = UIImage(named: "Image") // replace that with your UIImage let filename = "myimage.wai" let documentsPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, false)[0] as! NSString let destinationPath = documentsPath.stringByAppendingString("/" + filename).stringByExpandingTildeInPath UIImagePNGRepresentation(image).writeToFile(destinationPath, atomically: false) let fileUrl = NSURL(fileURLWithPath:

Till now after searching what i know is, in iOS , notifications cannot be handled, once the app is killed , and after that app is launched by tapping app icon. i want to achieve what whatsapp does, i.e. 1) i kill whatsapp from multitasking swipe up. 2) i receive whatsapp 1 new message push notification. 3) then without launching whatsapp(through app icon or through notification) i disconnect mobile data/ wifi or any internet connection. 4) after disconnecting all connections, i launch whatsapp BY LAUNCHING IT FROM APP ICON(and not from notification). 5) then i find that those notification

WhatsApp developers recently improved the image loading in which immediately loading some portion of the image (getting its dimension and some pixels of the images) and then after loading the entire image, replace the placeholder with the full image: My question is, how did they implement it? Do they read the dimension of the image by reading its header (meta-data)? How about the image content? Or do they have two versions of the image at the server-side, a smaller one with low-quality which is loaded first and a bigger one which is the full image? Note that if it's the second approach then

I've spent an hours to find a way to send/share an image (and text if possible) into whatsapp app using react native, I've read this question (in android) and this question (using linking) on android, it is possible to send image and text to whatsapp, but on react native i don't see any way to archieve it, anyone have an idea? For react-native versions greater than 0.56.0 the social share functionality is already implemented in the library, so extra libraries like react-native-share are no longer needed and they could be unmantained. In fact, I was using react-native-share library some months

My findings I am designing a logic to sync contact with my Backend. I gone through some apps that doing same thing in IOS. I will take the example of WhatsApp, I found that When I update any contact in Native Addressbook, it reflect that change into Whatsapp withing a fraction. My Concern I just want to know that how it is syncing in a very faster way. Even a new contact gets synced with its Remote server and get displayed on contact, and with the ability to initiate Whatsapp chat if that number is registered one. Summary of Queries So, in nutshell my queries are, How Whatsapp is syncing the
