Android Emulator Tricks

When performing security (or regular) tests on Android applications, we sometimes need to emulate or fake mobile data or actions; making/receiving calls, sending SMS or setting the exact geo-location are some commands that can be done, using the Emulator Console.  Here are a few tricks that will help you through Android application testing using the emulator:

· First, connect to the emu, using telnet:

telnet localhost 5554

· To change geo-locations:

geo fix <longtitude value> <latitude value>

· To make a phone call to the emulator:

gsm call <callerPhoneNumber>

· To send an sms to the emulator:

sms send <senderePhoneNumber> <textMessage>

· To scale the emulator window:

window scale <value from 0 to 1>

· To take a screenshot:

screencap -p  </path/to/filename.png>

· To create input events (event codes list):

input keyevent  <event_code>


The Monkey is a command-line tool that runs on the emulator instance or on a device. When the Monkey runs, it generates pseudo-random events and sends them to the system.
