This is a small tit-bit I discovered today:
If you want to access your localhost through the Android Emulator - you need to use the IP Address 10.0.2.2 unlike how we do on the web browsers on our desktops where we access the local host as 127.0.0.1 or 'localhost' itself.
This information is useful if for testing purposes you have locally installed a webserver and put a few HTML pages or if you have locally hosted web services - say REST Services that need to be invoked through a URL like this: http://localhost:8080/rest/hello, then, use the above mentioned IP address and you will be able to access your service or webpage through the emulator.
Or you could simple use your own IP address like 192.168.3.233 - whatever yours is. If you do a "ipconfig" in a windows command prompt, you will know what your IP address is. (one of the ways to find it out). However, there is one disadvantage with this method if your IP is allocated to you dynamically on your network. This will keep changing. In such a case, using 10.0.2.2 will be the equivalent of 127.0.0.1 which will not change for the localhost.
Hope this helps.

ReplyDeleteYou've got a nice blog. The above post is something which many of starters would be glad to know. Only thing is, when running on MAC, since it comes with inbuilt local server, knowledge of console is must along with 3rd part mysql editors for convenience. Alternatively, MAMP is also an option.
ReplyDeleteGlad to be here and sure will be back.

ReplyDeleteFirst of all, this is a great blog and I would like to thank you for all the information you've been sharing throught it.
ReplyDeleteNow, for people using Genymotion ( http://www.genymotion.com/ ) as their emulator, it would be worth noting that the IP address to connect to localhost is 10.0.3.2 instead of 10.0.2.2.
Keep up the good work.
