I want to send the data to Dadabase.here below I enclose my remaining codes.so please check and clear my problem.please

Private HttpResponseDoresponse(Stringwr.) {

HttpClientHttpClient= New Defaulthttpclient(Gethttpparams());

HttpResponseResponse= Null;

Try {
Switch (TaskType) {

CasePost_task:
HttpPostHttpPost= New HttpPost(wr.);
ADD parameters
HttpPost.Setentity(New Urlencodedformentity(Params));
Response=HttpClient.Execute(HttpPost);

Break;
CaseGet_task:
HttpGetHttpGet= New HttpGet(wr.);
Response=HttpClient.Execute(HttpGet);
Break;
 }
} Catch (ExceptionE) {

Log.E(TAG,E.Getlocalizedmessage(),E);

}

ReturnResponse;
}







Private StringInputstreamtostring(InputStream Is) {

StringLine= "";
StringBuilderTotal= New StringBuilder();

Wrap a bufferedreader around the InputStream
BufferedReaderRd= New BufferedReader(New InputStreamReader(Is));

Try {
Read response until the end
While ((Line=Rd.ReadLine()) != Null) {
Total.Append(Line);
}
} Catch (IOExceptionE) { 
                 log e (tag, E getlocalizedmessage (),  E);              } 
 
         & nbsp   //Return full String 
             return Total.         } 
         

I get NullPointerException in the line below,

result = inputStreamToString(response.getEntity().getContent());.

I don't understand about entity and content.anyone can help me??

Workaround 1:

Your HTTP response has not been completed entity . That's why it's getEntity() returned null .

The JavaDoc of GetEntity () indicates that a null value can be returned. Therefore, you should always check the.

For example, instead of:

result = inputStreamToString(response.getEntity().getContent());

You can do this:

Final HttpentityEntity=Response.GetEntity();
If (Entity== Null) {
Log.w (tag,  "the response has no entity."  
 
     // note:this method would return "" in the case, so we mu The St check for so in OnPostExecute ().  
 
     //do whatever are necessary here ...  
 } else  { 
     result = inputstreamtostring  (entity. Getcontent 
 }            /span>               

I get an HTTP response, but response.getentity (). GetContent () displays a null pointer exception
