having issues with sip api support

i am creating sip application. i am testing it on my micromax a26 and it has android 2.3.5 and i am having problems
-->1
when i am executing this code
if(SipManager.isApiSupported(getApplicationContext()))
Toast.makeText(getApplicationContext(), "support", Toast.LENGTH_SHORT).show();
else
Toast.makeText(getApplicationContext(), "not support", Toast.LENGTH_SHORT).show();
i am getting "not support" alert.
in this http://developer.android.com/guide/topics/connectivity/sip.html it says i need You must have a mobile device that is running Android 2.3 or higher.
what i am missing???
-->2
at this line
if(manager == null) {
manager = SipManager.newInstance(this);
}
if (manager == null) {
Toast.makeText(getApplicationContext(), "manager null", Toast.LENGTH_SHORT).show();
return;
}
i am again getting alert "manager null" so i can guess that SipManager.newInstance(this) is retuning null. see this http://developer.android.com/reference/android/net/sip/SipManager.html#newInstance%28android.content.Context%29

Added all permission in AndroidManifast.xml file. Where I am doing wrong? Should i have to use AsyncTask to update location in background?

If its because of NULLPOINTER EXCEPTION then please do add null safety for location object.I had faced similar kind of problem in nexus device.
if(location != null){
latitude = location.getLatitude();
}

First, I would read up on Android activity lifecycle. Personally I think this is the way begin to address the issue -
http://developer.android.com/training/basics/activity-lifecycle/index.html
Another option to investigate -
android:configChanges="orientation|keyboardHidden|screenSize"
how to stop activity recreation on screen orientation?

Try this in your Activity Tag of Manifest file :
<activity android:name=".MyActivity"
android:configChanges="orientation|keyboardHidden"
android:label="#string/app_name">
Here Orientation refers to Configuration changes which you want to handle by your own.
To declare that your activity handles a configuration change, edit the appropriate <activity> element in your manifest file to include the android:configChanges attribute with a value that represents the configuration you want to handle.
Use onSaveInstanceState() and onRestoreInstanceState() if you want to restore your previous state of an activity.
Refer this also

You may try to call setRequestedOrientation() in you activity so the orientation is forced.

Uploading xml file to server using Android Service

onStartCommand intent:
This may be null if the service is being restarted after its process
has gone away, and it had previously returned anything except
START_STICKY_COMPATIBILITY.
http://developer.android.com/reference/android/app/Service.html
So try use:
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
startActivity(intent);
rather than finish();
