Problems while importing an image asset

Question

I'm trying to import a PNG image asset to my project. But the image is losing details. It's just retaining the outer background. The image is transformed to a solid asset:

As you can see, the source asset has a white-tick in the center. But, after importing, it just remains as a solid circle with no ticks. Any solutions?

UPDATE: Tried Android asset studio, but with the same result. What am I missing?:

Thanks to Shafayat Mamun, a workaround is figured out. Here's what I did:

1. Go to Android Asset Studio
2. Select Generic Icons (it didn't work for any other option)
3. Upload the image, pick your color and drag down the color scale to 0% using the scale.
4. Download the zip and extract to the main folder of the project.

PS: This, though helped me solve my query, but the question remains intact. Why is android studio not capturing the image details while importing? Same is the case while I select Action bar and tab icons in the Android Asset Studio.
