Why show error OutOfMemoryError with android 2.3

Question

I use the ksoap2 to get data from server (My data about 6MB) My code:

                   SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                    SoapEnvelope.VER11);
            // envelope.dotNet=true;
            envelope.setOutputSoapObject(request);
            HttpTransportSE androidhttpTranport = new HttpTransportSE(URL,
                    ContantSystem.TimeOut);
            androidhttpTranport.call(SOAP_ACTIONS, envelope);

            Object responseBody = null;
            try {
                responseBody = envelope.getResponse();
            } catch (SoapFault e2) {
                // TODO Auto-generated catch block

            }

When i synchronization data, my app show exception:

Affter I set android:largeHeap="true" If i run my app on android 4.0.3, my app runs ok. But I run my app on android 2.3, my app die and show exception : java.lang.OutOfMemoryError Why? How does disentanglement this problem? Thanks.

Without code, we can't know why this happened. But in general, memory management in Android is a real pain... See http://stackoverflow.com/q/9986385/544198 — PearsonArtPhoto, Nov 20 '12 at 10:46

What kind of data is this ?

Maybe you or the library is reading the data in a single block, that may not be a good idea, try reading it in small buffers, then store it in a file cache.

You can use ActivityManager.getMemoryClass() and ActivityManager.getLargeMemoryClass() to make sure that more memory has been assigned. Give that a try.

I can't call int lag=activityManager.getLargeMemoryClass(); in android 2.3. It is error: Call requires API level 11 (current min is 9): android.app.ActivityManager#getLargeMemoryClass. Why? Do you know? android:largeHeap="true" not active in android 2.3? – mum Nov 20 '12 at 11:25
