Splash Screen for Android in React Native - react-native

I've followed this.
https://android.jlelse.eu/change-splash-screen-in-react-native-android-app-d3f99ac1ebd1#.5k7trorbf
But this is just creating a specific size for all dimensions. What should i do for other dimensions? I've already generated all the dimensions images and have put them in drawable-xxxx folders. But still specific dimension for all dimensions.

I've got success by using <nine-patch> instead of <layer-list> and the images with .9. We've to generate splash from online generators which generate images to be compatible to nine patch. This will stretch the image according to dimensions.

How to disable anti-aliasing in the image using the Panalleum library

I have images loading with some issue. I am using Panalleum library to load the images.
If I zoom out and see the same image, there you would see some small dots creating lines. This is related to Anti-Aliasing.
How can I fix this blurriness or lines on the image?

Custom MapIcon image wrong size in UWP app

I've got a UWP app with a map view. For some of my MapIcons, I need to set a custom image. Others use the default image. My custom image is approximately the same size as the default image. Additionally, I generated different sizes for different screen scales, and named them accordingly (for example, MyIcon.scale-200.png, etc).
I tested this by running the app on my computer, a Surface Pro, and setting the scaling to different values in the Settings app. It seems to work. As I choose larger scales, I get larger custom MapIcons, and the custom icon is similar in size to the default icon.
However, my customers report that it is not working correctly when I distribute my app. They are sending me screen shots that show the custom MapIcon either much larger, or noticeably smaller than the default one. I can't reproduce or explain these results.
What could cause this?

Image size changing from Expo to App Store

When running my application in Expo all images look fine and lovely, it's just when I deploy to the app store suddenly my images are huge.
I made sure that I follow Expo's standard on image spec as written here;
https://docs.expo.io/versions/latest/react-native/images/
Even weirder is the images look fine on iPhone X but the size is off on iPhone 7 (but on that same iPhone 7 in Expo everything looks ok). So just wondering if anyone has experienced any issues going from Expo to App Store with images and if they did how did they solve them?
Note: I am yet to deploy to Google play so haven't been able to see the effects there yet.
All input greatly appreciated
Just try to use WIDTH and HEIGHT from Dimensions
And then set width to your image by multiplication of WIDTH on some coefficient.

Image sizes for android and iOS in react-native

While making iOS Apps, we generally used to supply #x,#2x,#3x images. And based on my knowledge in case of android, there was some approx six different sizes
I have started working on react-native and came across the image issue.
My Question are: Do I need to provide images with all different sizes (i.e. approx 6-7 image sets by combining iOS and android) Or only 1 image and rest will be taken care internally? Will it look blurred on higher resolution phones?
Thanks.
You still need to provide multiple images. According to the Images documentation, if you are using an image named check.png, you also have to include check#2x.png and check#3x.png.
Quoting:
The packager will bundle and serve the image corresponding to device's
screen density. For example, check#2x.png, will be used on an iPhone
7, whilecheck#3x.png will be used on an iPhone 7 Plus or a Nexus 5. If
there is no image matching the screen density, the closest best option
will be selected.

Custom icons on google map not drawing correctly

I'm having problems with google maps, drawing icons was working fine few weeks ago in my project. At some time the icons are very frequently drawing in partly and I don't know what is causing it. It is both happening on my development machine and production server and on all machines.
I'm only using two different icons so I know the bitmap images are not corrupt.
Here below are two sample images.
You'll get more help if you post your outputted JSON. Your gmaps JSON must not have quotes around width or height, like so: "picture":"/assets/dayhome.png","width":32,"height":37,"lat":53.5402,"lng":-113.628
Another fix is to include optimized:false which disables the html5 canvas (the squares that are cutting off the markers).
My much more detailed analysis here: Canvas Tiles Cut Off Custom Markers
Set optimized:false in your Marker options.
If optimized is true (the default), then your marker images are incorporated into the tiles. Unfortunately where markers cross tile boundaries, they are not also used on the adjacent tile, so appear to be truncated at the edge of the tile. Using optimized:false forces the icons to be placed on the map as separate DOM objects.
