Android Flush DNS

Question

We recently released an android application that pulls information from an external server   Last week we moved from shared hosting to a dedicated server  that went smoothly up until we started getting complaints that users were getting server not found errors   We checked on our android-based phones  Droid  and everything worked fine   The vast majority of users are fine  there seems to be a small percentage of t-mobile users running android o s 1 5  g1  mytouch 3g  that seem to be having trouble   We believe these are all previous users of the application   Anyway  we ve been trying to find a fix  similar to ipconfig  flushdns  but have been unable to do so   Has anyone had experience with something similar to this   Thanks

Perform a hard reboot of your phone  The easiest way to do this is to remove the phone s battery  Wait for at least 30 seconds  then replace the battery  The phone will reboot  and upon completing its restart will have an empty DNS cache   Read more  How to Flush the DNS on an Android Phone   eHow com http   www ehow com how 10021288 flush-dns-android-phone html ixzz1gRJnmiJb

copied from  https   android stackexchange com questions 12962 flush-clear-dns-cache  Addresses are cached for 600 seconds  10 minutes  by default  Failed lookups are cached for 10 seconds  From everything I ve seen  there s nothing built in to flush the cache  This is apparently a reported bug http   code google com p android issues detail id 7904  in Android because of the way it stores DNS cache  Clearing the browser cache doesn t touch the DNS  the  hard reset  clears it

You have a few options    Release an update for your app that uses a different hostname that isn t in anyone s cache  Same thing  but using the IP address of your server Have your users go into settings -  applications -  Network Location -  Clear data    You may want to check that last step because i don t know for a fact that this is the appropriate service  I can t really test that right now   Good luck
