AsyncTask's get() method's behavior changed with different API levels

Question

My app's targetSdkVersion is 11. I need to upgrade it to 14 or upper. Unfortunately my current code heavily depends on codes like this.

int timeout = 5000;  
return new HttpMnagerAsync().execute().get(timeout, TimeUnit.MILLISECONDS);

In targetSdkVersion 11: This code execute the method HttpMnagerAsync()'s doInBackground() immediately and wait for 5 seconds for complete the execution and return the results. If failed to finish in 5 seconds a timeout exception returns. (This is the expectation)

When changed to targetSdkVersion 14: This code waits 5 seconds doing nothing, and it returned timeout exception, and then it hits the HttpMnagerAsync()'s doInBackground() method.

I need to upgrade the targetSdkVersion to 14. any explanation is appreciated to overcode this issue.

Calling get() will not make Asynctask asynchronous, get() waits for the result blocking the ui thread. Remove get() and use execute like for example:

new HttpMnagerAsync().execute();

Then, you can set your timeout in Http client, for example:

try
{     
   HttpGet httpGet = new HttpGet(url);
   HttpParams httpParameters = new BasicHttpParams();

   // Set the timeout in milliseconds until a connection is established.
   // The default value is zero, that means the timeout is not used. 
   int timeoutConnection = 5000;
   HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);

   // Set the default socket timeout (SO_TIMEOUT) 
   // in milliseconds which is the timeout for waiting for data.
   int timeoutSocket = 6000;
   HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);

   DefaultHttpClient httpClient = new DefaultHttpClient(httpParameters);
   HttpResponse response = httpClient.execute(httpGet);
} 
catch (ConnectTimeoutException e) 
{
    //Here Connection TimeOut excepion    
    Toast.makeText(xyz.this, "Your connection timedout", 11000).show();
}
