I'm new to the Android Vector Drawables which was introduced in the API level 21. I'd like to know that how can I convert my existing project icons which are in the PNG format, into the SVG file (Vector Drawables)?
If you are using default Android icons, you can right click on the "drawables" folder in your project and go to: New > Vector Asset. Here you can search all the android icons and add the vector assets (in whatever size) to your project.
If you are using custom icons, you can usually export them as svg's from your editing software. If not, you can google for icon to svg/vector drawable converters.
You can use the vector drawables the same way you would any normal drawable.

I have button design which created using Adobe XD. I want to use this design in my android button. How can do this. I can get this design as an .png or .svg. I don't want the background to deteriorate.
It depend how the design looks like in Adobe XD.
If your problem is decision how to use resource from XD as background so it will not "deteriorate", you have two options:
PNG: Download resource as .png and add in different sizes to adequate res folders. Documentation about resources on Android. Check part about resouces depending on Screen pixel density
SVG: Download resource as .svg and convert it to .xml in Android Studio to use as Vector Drawable. Then use it as a background of button. Vector Drawable will scale to the different resolutions without quality decrease.
Why I can't add an .svg file with effects such as drop shadows, blurs, and color matrix as a drawable resource in Android Studio?
Because Android's drawables are not SVG. You can create xml drawables fron SVGs. The format of Android's vector drawablea is similar to SVG, but it is not the same.
If you want all the effects you mentioned, you'll probably have to create bitmap images in various resolutions in a graphics program that fully supports SVG and use those bitmap images (PNG for instance) for your app, putting them in the correct drawables folders.
By default, Android creates the mipmap directories for the icons. But, the support for Vector images is provided starting with Android Support Library 23.2. Vectors are recommended for small resolution images(less than 200dpx200dp recommendation) and keeps the App size down.
So, why can't we use(or why is it not recommended) vector images for App icon instead by default?
You can change default icon and use your own app icon. By creating vector icon.
Right click on resources and create a new vector image from there.
Are there online tools to convert png file to vector drawable files (xml in Android)?
I have few pngs that I was using for icons & various places in my app.
So, now I want to convert them to xmls. Is it possible to do so?
Ok, so you can convert PNG to Android vector drawable following these steps
Step 1:
Convert PNG to SVG (Scalable Vector Graphics)
https://www.autotracer.org/
Or you can use any online converter of your choice
Step 2:
Use the generated SVG in step 1 and convert it to Android vector drawable using this link
http://inloop.github.io/svg2android/
http://a-student.github.io/SvgToVectorDrawableConverter.Web/
Alternatively you can also use Android studio to generate Vector drawables from SVG generated in Step 1.
Inside Android studio, right click on your drawable folder
New > Vector Asset
This will open up the Android studio Vector asset generator.
Select a local SVG file (the one you generated online)

I made simple menu icons which look the way I want them to look when in Illustrator, but when I place them in my app they look pixelated and bad.
Here is it in my app (as you can see, the text is not pixelated):
This is how it looks in Illustrator (I cut the icons and pasted them next to the other two, that's why the background is in different color):
I made the icons on 72x72 px canvas and exported them as .png file.
I am using Android Studio to make my app, and use simple
android:background="#drawable/back_button" to set the image/icon for the ImageButton.
I never try Illustrator to put icons, but I am directly download icons from flaticon that provides any type of file and size too
Two way to get different canvas file in android studio.
Android Studio-> File-> Image Asset or Vector Asset
upload your file and set as you need
Icon Generator
From this you can get directly res folder with different canvas image.
Mostly I prefere first.
Thanks
these icons as shown in fig. have a background color assigned by you in illustrator, no matter these are exported as png format or jpg!
First go back to illustrator and try to make background of images transparent as you assigned greyish color, tell me if it works. That's great you are making icons for yourself. Good work.
I think when you save the file please try to save it (SVG) format & then place it.
