通过命令行启动无数据的Android仿真器

Question

I'm trying to figure out how to launch an emulator with no data connection or airplane mode, either one will work. Im testing my application against data loss, however I need this to be atomized. Therefore I'm trying either to launch the emulator with no data via command line, or write bash script to launch emulator, turn data off, then run Unit Test.

RESOLVED - Per Recommendations

#! /usr/bin/expect

set timeout 10
spawn telnet localhost 5554
expect "OK"
send "gsm data off\n"
send "quit\n"

Answer 1

The quick and dirty way to do it could be to make an app that starts at boot and turns data off, then run the emulator and install the app. This does have potential for inconsistency however.

The other thing you can do to leave just the emulator without a network is to telnet into the emulator and turn data off. To automate it, I made a simple (and crude) example using a batch file and vbscript to feed telnet the commands since my work machine is running Windows.

The batch file:

@echo off
emulator -avd YOURAVDNAMEHERE
timeout /t 10
telnet_turn_data_off.vbs

telnet_turn_data_off.vbs :

set oShell=CreateObject("WScript.Shell")

oShell.Run "telnet localhost 5554", 9
WScript.sleep 500

oShell.Sendkeys "gsm data off{ENTER}"
WScript.sleep 500

oShell.Sendkeys "gsm voice off{ENTER}"
WScript.sleep 500

oShell.Sendkeys "quit{ENTER}"
WScript.sleep 500

oShell.Sendkeys "quit{ENTER}"
WScript.sleep 500

If running on Linux or Mac OS, expect should be able to script telnet (as seen by the edit to the question).

It is also worth noting that on older emulators (eg 2.2), turning data off might not do anything . My above example was tested with a 4.2 emulator and it appeared to cut off data properly.

Answer 2

I typically use physical hardware for testing instead of emulators, but if you can't find an option to enable airplane mode you could simply disconnect your computer from the internet before launching the emulator. No internet for your computer = no internet for your emulator.

Use This Following steps..

Go to Eclipse

Window->show view->other->android->Devices now select your running emulator and Again

Go to,

Window->show view->other->android->Emulator Control Now in that..set Data to Unregister from Home

From Device and Emulator

In Device or Emulator Go to,

Setting -> Wireless & networks -> Airplane Mode -> ok
