I ve seen this problem in the emulator as well   In my case  it is caused by launching the emulator  then putting the computer to sleep or changing the network connection  going from work to home  etc   then attempting to use the same emulator again   Closing and re-launching the emulator resolves the problem in this case

Unable to resolve host         No address associated with hostname  I had this issue and I solved it by this way  change   http   hostname abc def ghi name php  to  http   ipaddress abc def ghi name php   http   97 68 XX YY abc def ghi name php  I solved this by this way   you have to give server ip address instead of hostname servername   Please try this and comment your feedback

If you are running the app on an emulator  make sure that it is properly connected to the internet  If it is not  the easiest way of solving it is reopening the emulator or creating a new device

You probably don t have the INTERNET permission  Try adding this to your AndroidManifest xml file  right before  lt  manifest gt     lt uses-permission android name  android permission INTERNET    gt    Note  the above doesn t have to be right before the  lt  manifest gt  tag  but that is a good   correct place to put it   Note  if this answer doesn t help in your case  read the other answers

it seems you are trying to resolve this host   which is invalid   Check for rss URL  Update Following are the possibilities   1 Your browser is configured with proxy  app not  System setProperty  http proxyHost    my proxyhost com    System setProperty  http proxyPort    1234      2 Your browser has access to internet  not app  3 can be an SSL issue if URL is secured

Unable to resolve host         No address associated with hostname   you must have to check below code here on your manifest     lt uses-permission android name  android permission INTERNET    gt    and most important at least for me -  enabled wifi connection or internet connection on your mobile device

Sometimes  although you add  lt uses-permission android name  android permission INTERNET    gt  in the AndroidManifest and you have a WiFi connection  this exception can be thrown  In my case  I have turned off WiFi and then turned it on again  This resolved the error  Weird solution  but sometimes it works

Check permission for INTERNET in mainfest file and check network connectivity

User · Answer

It could be due to below reasons  -   Either you dont have INTERNET permission in manifest file  If so then please use this statement  lt uses-permission android name  android permission INTERNET    gt  Or you are connected to a network but your internet connection is not working  Like you are connected to a Wi-Fi but it doesnt have internet connection or Mobile data on your phone is ON but you dont have data connectivity on your phone     Point  2 is interesting and its not assumption  I have tested the same at my end   Hope this will help you  Summved
