24. Shell

24.1. Android Debugging Bridge - Shell

You can access your Android emulator also via the console. Open a shell, switch to your "android-sdk" installation directory into the folder "tools". Start the shell via the following command "adb shell".

    
adb shell

   

You can also copy a file from and to your device via the following commands.

    
// Assume the gesture file exists on your Android device
adb pull /sdcard/gestures ~/test
// Now copy it back
adb push ~/test/gesture /sdcard/gestures2 
   

This will connect you to your device and give you Linux command line access to the underlying file system, e.g. ls, rm, mkdir, etc. The application data is stored in the directory "/data/data/package_of_your_app".
If you have several devices running you can issue commands to one individual device.

    
# Lists all devices
adb devices
#Result
List of devices attached
emulator-5554 attached
emulator-5555 attached
# Issue a command to a specific device
adb -s emulator-5554 shell

   

24.2. Uninstall an application via adb

You can uninstall an android application via the shell. Switch the data/app directory (cd /data/app) and simply delete your android application.
You can also uninstall an app via adb with the package name.

    
adb uninstall <packagename>
   

24.3. Emulator Console via telnet

Alternatively to adb you can also use telnet to connect to the device. This allows you to simulate certain things, e.g. incoming call, change the network "stability", set your current geocodes, etc. Use "telnet localhost 5554" to connect to your simulated device. To exit the console session, use the command "quit" or "exit".
For example to change the power settings of your phone, to receive an sms and to get an incoming call make the following.

    
# connects to device
telnet localhost 5554
# set the power level
power status full
power status charging
# make a call to the device
gsm call 012041293123
# send a sms to the device
sms send 12345 Will be home soon
# set the geo location
geo fix 48 51
