Android Emulator vs Real Device

by

I am aware of these limitations:

  1. Pre-installed software. Real device can have preinstalled a lot more applications than emulator.
  2. You cannot use “capture” photo/video functions in emulator.

According to emulator documentation, its limitations are:

The functional limitations of the emulator include:

  • No support for placing or receiving actual phone calls. You can
    simulate phone calls (placed and received) through the emulator
    console, however.

  • No support for USB connections

  • No support for device-attached headphones
  • No support for determining network connected state
  • No support for determining battery charge level and AC charging state
  • No support for determining SD card insert/eject
  • No support for Bluetooth

IMO you can use emulator to simplify UI development, to view UI on “device screen”, to be sure that app layout is ok, app can be run, you can test some special cases by simulating gps position, network speed or messaging etc. But testing on real device is a must.
