Title: Android: Setting network latency Tags: android|android-networking

You can create network latency on either the emulator via telnet. Telnetting to port 5554 on localhost will give you access to the first emulator connected. (http://developer.android.com/tools/devices/emulator.html#console see there for more information)

Then type 'network status' to see what's currently set. 'network delay [num]' allows you to set it by a predefined about. 'newwork delay gprs' allows you to set the delay to the range gprs would give you.

 $ telnet localhost 5554
 Trying 127.0.0.1...
 Connected to localhost. Escape character is '^]'.
