For those saying that the answer of  kuester2000 does not work  please be aware that HTTP requests  first try to find the host IP with a DNS request and then makes the actual HTTP request to the server  so you may also need to set a timeout for the DNS request    If your code worked without the timeout for the DNS request it s because you are able to reach a DNS server or you are hitting the Android DNS cache  By the way you can clear this cache by restarting the device   This code extends the original answer to include a manual DNS lookup with a custom timeout     Our objective String sURL    http   www google com    int DNSTimeout   1000  int HTTPTimeout   2000     Get the IP of the Host URL url  null  try        url   ResolveHostIP sURL DNSTimeout     catch  MalformedURLException e        Log d  INFO  e getMessage        if url  null         the DNS lookup timed out or failed       Build the request parameters HttpParams params   new BasicHttpParams    HttpConnectionParams setConnectionTimeout params  HTTPTimeout   HttpConnectionParams setSoTimeout params  HTTPTimeout    DefaultHttpClient client   new DefaultHttpClient params    HttpResponse httpResponse  String text  try         Execute the request  here it blocks the execution until finished or a timeout      httpResponse   client execute new HttpGet url toString        catch  IOException e          If you hit this probably the connection timed out     Log d  INFO  e getMessage          If you get here everything went OK so check response code  body or whatever   Used method     Run the DNS lookup manually to be able to time it out  public static URL ResolveHostIP  String sURL  int timeout  throws MalformedURLException       URL url  new URL sURL         Resolve the host IP on a new thread     DNSResolver dnsRes   new DNSResolver url getHost         Thread t   new Thread dnsRes       t start          Join the thread for some time     try           t join timeout         catch  InterruptedException e            Log d  DEBUG    DNS lookup interrupted            return null               get the IP of the host     InetAddress inetAddr   dnsRes get        if inetAddr  null            Log d  DEBUG    DNS timed out             return null               rebuild the URL with the IP and return it     Log d  DEBUG    DNS solved         return new URL url getProtocol   inetAddr getHostAddress   url getPort   url getFile            This class is from this blog post  Go and check the remarks if you will use it   public static class DNSResolver implements Runnable       private String domain      private InetAddress inetAddr       public DNSResolver String domain            this domain   domain             public void run             try               InetAddress addr   InetAddress getByName domain               set addr             catch  UnknownHostException e                         public synchronized void set InetAddress inetAddr            this inetAddr   inetAddr            public synchronized InetAddress get             return inetAddr

An option is to use the OkHttp client  from Square   Add the library dependency  In the build gradle  include this line   compile  com squareup okhttp okhttp x x x    Where x x x is the desired library version   Set the client   For example  if you want to set a timeout of 60 seconds  do this way   final OkHttpClient okHttpClient   new OkHttpClient    okHttpClient setReadTimeout 60  TimeUnit SECONDS   okHttpClient setConnectTimeout 60  TimeUnit SECONDS       ps  If your minSdkVersion is greater than 8  you can use TimeUnit MINUTES  So  you can simply use   okHttpClient setReadTimeout 1  TimeUnit MINUTES   okHttpClient setConnectTimeout 1  TimeUnit MINUTES     For more details about the units  see TimeUnit
