[Android self-study Note] corresponds to the Icon size in the resource folder

After the application is completed, it is very important to configure an icon. The android ADT provides the android icon set. You can create an icon.

However, I found that it is not very useful when using it, especially when I put the PNG image of the rounded corner, it will add white in the four corners, making it very difficult to see, PS: I am very grateful if anyone knows how to set the background color to transparent.

So I manually zoomed in and out the icons and placed them under different resource files. Here we will record the sizes of Several icons used, and you can view them directly when using them:

LDIP: 36*36

MDIP: 48*48

HDIP: 72*72

Xhdip: 96*96

Ic_launcher-web: 512*512

We recommend that you use a PNG image.

I 've been reading in-app billing in recent days. Currently, there is not much information on the Internet. Write an article after I have finished it.
