Continue the android learning journey. Today, we use a small example to get the SD card capacity and the phone ROM capacity. The Code is as follows:
Package com. urovo. sdcardspace; import java. io. file; import android. OS. bundle; import android. OS. environment; import android. OS. statFs; import android. app. acti
