How To Remove Fatal Exception: Asynctask In Android

10-23 00:41:00.705: E/AndroidRuntime(3622): FATAL EXCEPTION: AsyncTask #1 10-23 00:41:00.705: E/AndroidRuntime(3622): java.lang.RuntimeException: An error occured while executing d

Solution 1:

The reason is you can only consume Content from Entity once.

You did it twice (maybe without you knowing it) in here

Readerreader=newInputStreamReader(response.getEntity().getContent());

and here

response.getEntity().writeTo(out);

I know this is sounds a little weird but actually the writeTo() function will get content from the entity to write to the OutputStream. You can see it in the documentation here

Another workaround you can use is turning it to string and let GSON handle it

@Overrideprotected String doInBackground(String... uri) {
    HttpClienthttpclient=newDefaultHttpClient();
    HttpResponse response;
    StringresponseString=null;
    try {
        response = httpclient.execute(newHttpGet(uri[0]));
        StatusLinestatusLine= response.getStatusLine();
        if(statusLine.getStatusCode() == HttpStatus.SC_OK){
            responseString = EntityUtils.toString(response.getEntity()); // content will be consume only onceGsongson=newGson();
            Holderresponse1= gson.fromJson(responseString, Holder.class);
        } else{
            //Closes the connection.
            response.getEntity().getContent().close();
            thrownewIOException(statusLine.getReasonPhrase());
        }
    } catch (ClientProtocolException e) {
        //TODO Handle problems..\
        progressDialog.hide();
    } catch (IOException e) {
        //TODO Handle problems..
        progressDialog.hide();
    }
    return responseString;
}

I hope my answer can help you!
