SVG looks strange on mobile browsers - android

Here's a PNG version of my logo image:
Here's a screenshot of an SVG version of my logo as seen on a PC:
Here's a screenshot of how that same SVG logo looks on an iPhone and an android phone:
What's going on? Why does the mobile version look so blurred and the gradient not work on the pink petal?
Here's the actual SVG code. (For some reason, the font doesn't load in the snippet code but it loads just fine from my website: http://www.cafenocturne.com/testpage/images/svg/CafeLogoFontSVG.svg

How to match Android Gradient Rendering with SVG BoundingBox Units

I am trying to replicate an SVG in Android vector drawable using the LinearGradient class. For bounding box gradient units, I am calculating the endpoints of the gradient line segment by using the following formula:
x1 = graphic_bound.left + graphic_bound.width() * svg_boundingbox_width_percentage
and
y1 = graphic_bound.top + graphic_bound.height() * svg_boundingbox_height_percentage
I am observing that the above works well for cases where graphic_bound.width() == graphic_bound.height()
But the rendering is different from SVG when the graphic bounds are non-square (width is not equal to height).
Any suggestions on what is the error here?
For example, the below SVGs look the same, one uses objectBoundingBox and another uses userSpaceOnUse units. My question is how to convert the objectBoundingBox values to userSpaceOnUse values to have the same visual appearance?

This is how I'm currently doing it:
var byteArray = Encoding.ASCII.GetBytes(svgStoredAsString);
using (var inputStream = new MemoryStream(byteArray))
{
var svg = new SkiaSharp.Extended.Svg.SKSvg();
svg.Load(inputStream);
using (var bitmap = new SKBitmap(100, 100))
using (var canvas = new SKCanvas(bitmap))
{
canvas.Scale(100 / svg.CanvasSize.Width, 100 / svg.CanvasSize.Height);
canvas.DrawPicture(svg.Picture);
canvas.Flush();
canvas.Save();
using (var file = File.OpenWrite(path))
using (var outputStream = new SKManagedWStream(file))
{
bitmap.Encode(outputStream, SKEncodedImageFormat.Png, 100);
}
}
}
((Image)image).Source = ImageSource.FromFile(path);
The svg shows just fine on the browser and even opens on Illustrator:
This is what I'm getting instead when rasterizing with my code:

How to create a vector drawable with inner path transparent?

I am trying to create a favourite icon something like the following icon.
While creating it i need the inner path (the area in blue color)to be transparent in the result.But while giving the transparent color it is showing the color that is filled in the outer path.i.e complete shape in orange color. How i can i make a vector drawable with transparent inner path
My vector drawable is

You have two ways to go:
1) create another vector drawable, which will draw only the outer line, instead of overlapping two hearts
or
2) remove the orange heart and add an orange stroke to the blue heart. Just copy the code below and try it. Be aware: half of the stroke width will go inside the image and half will go outside, so your image will differ a bit (stoke will be closer to the center of the image)

I added the file to ImageView
<ImageView
android:id="#+id/authorization_icon"
android:layout_width="120dp"
android:layout_height="120dp"
android:layout_gravity="center_horizontal"
android:layout_marginTop="#dimen/authorization_icon_margin"
android:layout_marginBottom="#dimen/authorization_icon_margin"
app:srcCompat="#drawable/rocketv"/>
And when I tried to inflate layout
setContentView(R.layout.activity_auth);
I caught the error:
android.view.InflateException: Binary XML file line #0: Error inflating class ImageView
But Android studio defines my picture without any problems. I can see it in activity_auth layout.
Solution 1:
For using VectorDrawable from java or to use it as background (in xml also) you need to intimate AppCompatDelegate to enable compat vector from resource. Below is the code for that.
static
{
AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
}
So define it this way
public class MainActivity extends AppCompatActivity {
static {
AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
}
upper side of OnCreate Method.
Solution 2 :
Whenever you are going to use VectorDrawable from java or to use it as background (in xml also) remember to use AppCompatView instead of normal view, here I have used AppCompatImageView
try like below.
replace app:srcCompat="#drawable/rocketv" with
android:src="#drawable/rocketv"
<ImageView
android:id="#+id/authorization_icon"
android:layout_width="120dp"
android:layout_height="120dp"
android:layout_gravity="center_horizontal"
android:layout_marginTop="#dimen/authorization_icon_margin"
android:layout_marginBottom="#dimen/authorization_icon_margin"
android:src="#drawable/rocketv"/>

SVG to Bitmap to ImageView

In my android app I try to get a Bitmap-Object from a SVG-File and store it in the cache. Then it should be displayed from this bitmap in an ImageView Object. I don't get it working, either the ImageView gets a wrong density, the Picture is too small or too large. May anybody tell me whats wrong with that code? For my purposes I use the AndroidSVG library (link). The Image should has 30dp width and height.
ImageView img = (ImageView)getView().findViewById(R.id.testingImage);
try {
int size = convertDPtoPixels(30);
SVG svg = SVG.getFromResource(mGlob.mContext,R.raw.vectorimage);
svg.setDocumentHeight(size);
svg.setDocumentWidth(size);
PictureDrawable pictureDrawable = new PictureDrawable(svg.renderToPicture());
Bitmap mutableBitmap = Bitmap.createBitmap(30, 30, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(mutableBitmap);
pictureDrawable.setBounds(0,0,size,size);
pictureDrawable.draw(canvas);
img.setImageBitmap(mutableBitmap);
} catch (SVGParseException e) {
e.printStackTrace();
}
Edit 30.3.2015
If I try to create the Bitmap with the Pixel-size like this, I get a too small Image (but it is sharp):
Bitmap mutableBitmap = Bitmap.createBitmap(size, size, Bitmap.Config.ARGB_8888);
Addition Information:
The Blue Color is the background color, from my ImageView. I use it to see where it starts and end, because my SVG has transparent surfaces. The SVG should fill the blue area...

You appear to be rendering the SVG to a 30x30 bitmap then scaling it up to (size x size).
Try changing the bitmap creation to:
Bitmap mutableBitmap = Bitmap.createBitmap(size, size, Bitmap.Config.ARGB_8888);
Update:
The problem is that Inkscape doesn't automatically give it's SVG files a viewBox.
Read this AndroidSVG FAQ question on how to deal with Inkscape files. https://code.google.com/p/androidsvg/wiki/FAQ#Dealing_with_Inkscape_files
You can either follow the advice there (which updates the SVG programmatically at runtime). Or alternatively, alter the SVG by hand. Make the following changes:
width="100%"
height="100%"
viewBox="0 0 30 30"
