Use complex SVG in android studio - android

I have a SVG file of a map. I can't convert with android studio I have this error : error while parsing svg .
I already convert it into png file but the quality deteriorates.
Or is it possible to convert .SVG to a list of draw functions with canvas.

Your text overlay contains characters that aren't UTF-8, which is typically the default if not specified.
This character is the first culprit â
Put this at the top of your svg document.
<?xml version="1.0" encoding="ISO-8859-1" standalone="no"?>
This may work in Android and it may not, but its a starting point. The first thing I would try to do is cut-up the SVG into smaller pieces and load it in square chunks because is huge. Its better to draw 30 smaller things than 1 big thing because you're suffocating the UI thread if you try to do it all at once.
Also Text in general doesn't seem to be support in the Android Studio importer

When i use .svg file "ERROR #<image> is not supported" in Android Studio

I want to create a Splash screen for my android application for this purpose i create ".svg" file by using three different ".png" images using Adobe XD. bust when i import ".svg" file through vector Asset it only show background of ".svg" image it does not show other images which i used to create this file for splash screen. I also used this http://inloop.github.io/svg2android/ to get proper ".xml" file and past it in drawable folder but still no change. I am attaching images of my error this is where error is shown
when i click on error foe more detail i I found this error
I want to use my app logo for splash screen "Please Help" me an tell me how to use logo on splash screen i just started android development.
Thankyou.
The Android Studio SVG importer only supports a subset of SVG. Remember that it is converting the SVG to a VectorDrawable. So only things that work in a VectorDrawable can be imported from the SVG. Basically that means you must stick to just the vector shapes - rectangles, ellipses, paths etc
See: Which SVG elements are supported by Android studio and which are not?
If your SVG only contains PNG images, then there is no point in using an SVG anyway. Just import your PNGs to your project and use an ImageView to display them.
If you really need to display an SVG. Then use a library that properly supports SVGs. Such as my one: AndroidSVG.

Android Studio does not import all parts of an SVG Vector

I want to import some vector graphics from illustrator for the design of my android studio app. If I export my vector graphics as SVG, this works wonderfully. All parts of my project are successfully exported and the result is satisfactory (image 1). However, when I create this SVG file as a new Vector Asset in Android Studio, one of my blue circles is suddenly missing (see image 2). What can be the reasons why Android studio does not import all parts of my SVG? Or could the reason be a wrong export from illustrator?
Edit: Added Picture 3 to show what happens if I use a online converter instead. The output is even worse.
Any Help is appreciated!

The version of the SVG that is displayed in the converter window is rendered by a built-in SVG renderer in Android Studio. It's a preview of the SVG. It does not necessarily reflect what the output of the converter will be.
So the bug you are seeing is with the built-in SVG renderer.
VectorDrawables don't really support gradient fills. At least the converter doesn't support them. So even if the displayed SVG were perfect, the generated VectorDrawable won't include the gradient circles anyway.
So you have a few alternative approaches:
Change your circles to solid fill and then convert to VectorDrawables.
Like #1, but add gradients by using predefined gradient definitions.
Use an actual SVG rendering library (like AndroidSVG) in your app.
Switch to using a bitmap background (ie PNG)
Draw the background yourself using Canvas methods.
Personally, I would go with #3.
Android Studio doesn't convert complex graphics into vector drawable. It only converts flat icons. You have to use a png here dude !!

Android Studio 3.0 vector drawables and LINT tools:ignore="VectorPath"

After upgrading to 3.0 Android Studio has started to complain about long paths in vector drawables.
The warning says:
Very long vector path (7958 characters), which is bad for performance.
Considering reducing precision, removing minor details or rasterizing
vector. less... (⌘F1) Using long vector paths is bad for performance.
There are several ways to make the pathData shorter: * Using less
precision * Removing some minor details * Using the Android Studio
vector conversion tool * Rasterizing the image (converting to PNG)
The documentation https://developer.android.com/guide/topics/graphics/vector-drawable-resources.html shows us how to use vector drawables in our apps, and recommends it over png's etc.
I have both been using the Android Studio Vector Conversion Tool and this excellent service for converting SVG's to vector drawables:
http://inloop.github.io/svg2android/
Are there other services that does more to reduce vector drawable complexity?
Where can I find guidelines on how 'advanced' my vector drawables can be?
Try optimizing the vector drawable using avocado! It should help reduce the complexity of your paths.
My path was around 1800 and i used svg-path-editor to lower to around 1000. Still showed the warning but quite close to the max 800
I am sure there is a better way to use this tool but i just copied the pathData from android studio xml to the Path box, pressed Round and got the result back to the xml
If your path is more than 2000, consider converting to png (with mdpi, hdpi, xhdpi...)
There's an extra step you can add before using svg2android, which is running it through svgo
An example pipeline that I use looks like (note that instead of the web tool, I'm using svg2vectordrawable)
~$ svgo image.svg --config=config -o image.svg.optimized
~$ s2v "image.svg.optimized image.xml
My config file looks like (you can play around with it to match your needs):
"plugins": [
{
"convertPathData": {
"leadingZero": false,
"floatPrecision": 2
}
}
]
Try to use this tool by decreasing Precision.
This may not be an ideal solution, but Initially I had drawn the vector asset in a single shot as a single object, this resulted in longer <path> problem. I started from scratch again and this time I split my object into many parts i.e. I drew each part of my single object individually and later I grouped them together (I used Inkscape). As a result, when .svg converts to .xml the single <path> tag gets split into multiple shorter <path> tags.

How do I export Android XML vector drawables to another format?

I want to recreate my app for iOS and the icons in Android are XML vectors with the "android:pathData" attribute. How do I convert these to an image that I can place into Xcode and use (preserving transparency)?
I have searched for a solution and found nothing and read the article on the Android Developer site on Vector Asset Studio but found nothing about exporting these drawables to something I can import into Xcode.
I did it by creating an SVG file and copying the value of the pathData attribute of the path element in the XML file and pasting it into the d attribute of the path element in the SVG file. I then converted it to PNG using ImageMagick.
So
<path android:pathData="[Path Data]">
becomes
<path d="[Path Data]">.
Then
convert -background none image.svg image.png
in the command line.
If there is a better way of doing this please post it.
After using the trick Questioner provide, I use a browser to open the svg file, zoom-in to the size as big as possible and take a screenshot. FYI.

Exception raised during rendering: Numbers of source Raster bands and source color space components do not match

I was trying to incorporate a image as a splash page for my android app. This image was created by one of my friends using photoshop. When I try to use this image as a background for my android application it says : "Exception raised during rendering: Numbers of source Raster bands and source color space components do not match" . Is there a way to fix this image non programatically, i.e. using photoshop or any other tools. If not is there any thing which can be done programatically.
This most probably is due to Bit Depth Field may be or any other image related properties because of which Eclipse IDE/ ADT is not able to render the image into ImageView.
The work around i use to convert same image into other format, In my case image was image.jpg which I converted to image.png using the Online Image Editor - Pixlr Editor
Hope this helps!!
