Android Studio - Android Emulator Wifi Connected With No Internet


Answer :

Stated below are the solutions for Windows and Mac, but similar solutions will work on any OS:

  1. On Windows

    • Open Network and Sharing Center and click on current Connection
    • Click on Properties
    • Double Click on Internet Protocol Version 4 (TCP/IPv4)

    • Set the Preferred and Alternate DNS servers as (Screenshot below) : 

      8.8.8.8 8.8.4.4

  2. On Mac

    • Go to Settings > Network > Advanced... > DNS

    • Delete whatever entries you have there and add these two entries (Screenshot below):

      8.8.8.8 8.8.4.4

      Note: For Mac users, if the entries field is disabled and you're not able to edit it, click on the 'Lock' icon in the bottom area of that window and enter the password to be able to make changes

Restart the emulator, and it should solve:

Edit: This is the fix for a situation when the emulator's wifi has changed the DNS to some non-working DNS. While this works most of the time, there might also be other reasons which may not fix from this solution.


My solution using Mac OSX 10.13

I read about it being caused by LAN card and WiFi being enabled, and some approaches seemed complicated to me, so I simply tried this, and it worked:

  • Disabled WiFi on my laptop.
  • Switched off the emulator.
  • Did a cold boot on the emulator (AVD Manager -> on emulator actions -> Cold Boot Now).
  • After reboot with laptop WiFi disabled the emulator showed proper WiFi connection (emulator still shows AndroidWifi but is connected to my laptop internet. WiFi symbol now look like this: WiFi symbol connected)
  • I then enabled WiFi on my laptop and everything worked.

@TheBaj : I figured the problem with this and fixed it. The problem is when you are connected through the router, the androidwifi in your emulator uses the settings and the sets the DNS to something other than 8.8.8.8 which is the google DNS(I presume this is kinda mandatory setting for the androidwifi to gain internet access). But if i change the DNS in my network settings, the google-services plugin which fetches your dependencies especially the one's getting downloaded from jcenter() will not be downloaded and hence your sync will fail which eventually fails your build.

So the trick is that you have your google DNS(8.8.8.8) configured in your network settings after your default router settings - this part takes care of downloading the dependencies from jcenter() and the sync and build succeeds.

Now launch your emulator with emulator @Nexus_5X_API_27 -dns-server 8.8.8.8 command from the terminal which forces the emulator to use 8.8.8.8 as its DNS and the emulator will have internet.

I am working on a react-native app, so for me android studio is needless and i have configured my bashrc to launch the different emulators as follows,

   function emunex5 {     emulator @Nexus_5X_API_27 -dns-server 8.8.8.8  }    function emunex6 {     emulator @Nexus_6_API_27 -dns-server 8.8.8.8   }    function emupix {     emulator @Pixel_XL_API_27 -dns-server 8.8.8.8    }

So from one terminal i launch the emulator of my choice and then run the build on another terminal which runs my app on the launched emulator and MY FREAKING EMULATOR HAS INTERNET ACCESS. :)

Try this out and i hope this helps.

Thanks, Vikram

Are Regular VACUUM ANALYZE Still Recommended Under 9.1?

Answer : VACUUM is only needed on updated or deleted rows in non-temporary tables. Obviously you're doing lots of INSERTs but it's not obvious from the description that you're also doing lots of UPDATEs or DELETEs. These operations can be tracked with the pg_stat_all_tables view, specifically the n_tup_upd and n_tup_del columns. Also, even more to the point, there is a n_dead_tup column that tells, per table, how much rows need to be vacuumed. (see Monitoring statistics in the doc for functions and views related to statistics gathering). A possible strategy in your case would be to suppress the scheduled VACUUM, keeping an eye on this view and checking on which tables the n_dead_tup is going up significantly. Then apply the aggressive VACUUM to these tables only. This will be a win if there are large tables whose rows never get deleted nor updated and the aggressive VACUUM is really necessary only on smaller tables. But keep running the ANALYZE for the optimiz

Can Feynman Diagrams Be Used To Represent Any Perturbation Theory?

Answer : Diagram machinery works also for perturbation theory in classical statistical mechanics and classical field theories. Generally, various kinds of diagrams constitute a pictorial way of talking about tensor products and their contractions while hiding the multi-linear algebra from the layman. In the simplest case, vertices (or blobs) represent vectors, matrices, tensors; vertices have ingoing and/or outgoing ports; ingoing ports denote (contravariant) ro indices; outgoing ports denote (covariant) co indices; directed arcs between blobs give a pair of equal indices summed over; different base spaces ⇔ \Leftrightarrow ⇔ different arc types; symmetric tensors ⇔ \Leftrightarrow ⇔ undirected diagrams; no labels are needed for internal lines. In many cases, the directed arcs are decorated (as thin, thick, broken,wavy, curly lines), each decoration indicating the presence of a so-called propagator, a function of its label to use as a weight in the sum, which may beco
