Creating Svg images reduces the effort of putting different resolution drawable (png's).

Steps to Create Svg images.

1. Right Click on drawable folder,Select New ,Select Vector Image. (view attachment vector_asset.png).
2. Choose the material icon / local svg(view attachment vector_asset2.png ) .
3. Name your resource file (view attachment vector_asset.3png).
4. Click next and Finish.

You will find new xml file in your drawable (ic_aspect_ratio_24dp in my case).

Add the generated xml to your source or background.

 <ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/imgThum"
    android:src="@drawable/ic_aspect_ratio_24dp"
    android:layout_below="@+id/btn_camera"
    />

It will supports all the resolution .
